How to prolong the service life of bearings?

Scrool Published :2013-3-31 16:49:24 Read: 96 【Font: Big Middle Small】
Theoretically centrifugal pump service life of rolling bearings NSK 20,000 to 80,000 hours, however, the actual life depends on many factors - NSK Bearings premature failure will lead to consideration of the high equipment downtime, and sometimes even lead more serious consequences. NKE (Austria) company NSK Bearings expert provides some simple but practical NSK Bearings performance optimization techniques.
     Satisfactory life begins NSK Bearings NSK Bearings correct choice. From the outset, NSK bearings for different applications through designers select the right NSK Bearings NSK Bearings to extend equipment life and performance. This process should consider many factors, such as load, hardness, NSK bearings life prediction, operating environment and so on.
     Correct storage
     In principle, all NSK Taper bearing prior to installation should be kept in their original packaging. They need to stay in a clean, moisture free, relatively constant temperature in the environment. Rolling NSK Bearings should stay away from dust, water and corrosive chemicals. Shaking and vibration may forever destroy the mechanical properties of NSK bearings, so the handling and storage process must avoid vibration.
     Basically, all levels of NSK bearings have to be saved, because some heavier NSK Bearings long vertically, it may be deformed due to its own weight.
     Pre-coated with grease (or sealed) NSK bearings need to be careful, because the oil after a long period of storage after the density change. NSK bearings so that when the first time, there will be a certain degree of rotation noise. Thus, the NSK bearings aside time should be controlled according to the FIFO principle.

China is expected to become SKF (SKF) largest market

 Recently, we passed SKF China CEO Ai Lan Germany learned, SKF new factory in China, this investment amounted to more than 600 million yuan, previously, SKF SKF Bearing Factory in Dalian has invested manufacturing plants, including large bearing plant investment of 1.5 billion yuan altogether, why SKF frequent large investment in China shot pen it. SKF bearings distributor in China, according to insiders regard, China is expected to become Sweden's SKF (SKF) Group's largest market. Currently, SKF's sales in China still behind the United States and Germany, why China is expected to become SKF (SKF) largest market? SKF distributor in China market analysis in the following three aspects.
1.SKF growth in China is mainly reflected in the business are: the automotive sector, including cars, trucks, and construction machinery. The second is the industrial market, OEM, the product sold to our customers, these products include trains, machine tools and new energy products; addition, the service, which is to do some more upgrading is to provide customers with service, maintenance, repairs.
     2. SKF Group's 2010 financial report: economic crisis caused by the Swedish SKF Taper bearing Group's sales and profits decline, but in 2010 there are still significant growth, reaching over 90 billion U.S., of which China sales of 7.3 billion yuan. SKF China Ltd in recent years maintained a growth rate of 30%, its sales have accounted for 12% of the Group's share of the growth rate at 30%.
     3 China and SKF (SKF) development opportunities: China is the world's largest economies in the world, we rarely see the other economies to have such a rapid development.

the selection to the right.

Lubricated Taper bearing fatigue life of rolling bearing and friction, wear, temperature, vibration, etc. have a major impact, there is no normal lubrication, INA bearings will not work. Analysis INA bearing damage causes that about 40% of all damage and lubrication INA bearings related to poor so good INA Bearing INA Bearing lubrication is to reduce friction and wear of effective measures. Additionally, INA bearing lubrication also heat, rust, sealing, ease shock effect. lubricant can not be guaranteed expired, the selection to the right. harvester INA bearing lubrication oil lubrication and grease lubrication points are two large oil-lubricated gearbox models choose to use GL-5 80W90 gear oil; grease lubrication generally with molybdenum disulfide lithium grease , lubricated by twisting the lower unit must continuously variable Mobil XHP222 or better grease lubrication, the importance of the bearing grease lubrication can be imagined, is to install the SKF bearing is the same, it's best to use good quality greased, do not use those lower inferior greased, so give us a bearing caused no small problem, if the SKF Bearings get damaged, and that loss is not the slightest bit.
Also: Bearing burns faults and solutions, the so-called burn injuries occur INA Bearing state is: INA bearings raceway wheel, roller and cage sharp fever in the rotation until discoloration, softening, deposition and breakage. SKF Bearing burns caused mainly due to poor lubrication INA Bearing, may not be using regular lubricant or lubricant too much, too little, is not correct. Secondly may be too large loads (preload is too large). Speed ??is too large. Clearance is too small. Water or other foreign matter intrusion. If neither of the above is then that axis, INA precision backing bearings box is bad, shaft deflection.
See here, I think everyone wants to know the solution right, first of all, to study the lubricant and lubrication method, the election of INA bearing lubricant, its dosage, but also to correct the INA bearing selection. Research to tie, INA bearing clearance and preload, and improved sealing device. Check the shaft and bearing housing INA precision. Of course we have here is an example of INA bearings, SKF bearings in fact is the same, the same will be such a failure occurs, the solution is the same.

Bearing lubrication methods and the advantages and disadvantages
1, the purpose of lubrication
Lubrication of rolling bearings are designed to reduce internal friction and wear of the bearing to prevent burning stick, its lubricating effect is as follows:
1) to reduce friction and wear
Constituting the bearing rings, rolling elements and cage of each contact portion to prevent the metal contacts, reducing friction and wear.
2) fatigue life

Computer fan bearing mute

You for your computer fan products sold well and worry about it? Your computer fan noise at work is the result of poor sales of the big reasons you? Guoping bearing three decades of production services, to provide you with the absolute highest quality mute ball!
State calm tone ball inexpensive to make your fan noise conditions at zero cost of production is low, is your good choice.
Due to the general computer fan noise is large, in a certain extent, affected the user's work and life, so they demand more and more fans, the general noise of the fan is difficult to meet the user's requirements. In addition to the computer fan blade cutting the air turbulence noise is generated, the bearing friction is brought about by the mechanical noise of the big decision factor. So, in order to reduce mechanical friction noise, Guoping bearing Electrical Company based on the principle of rolling friction rolling bearings is largely quiet fan reduces mechanical friction, avoiding noise. It is a precision miniature ball bearings, using chromium bearing steel, bearing materials containing chromium only enhance the wear resistance of the material, but also enhances the bearing strength. Precision ball Precision bearing can withstand axial load. Guoping bearing mechanical and electrical companies bearing the rated speed of <10000rpm/min, maximum speed <30000rpm/min, meet a considerable extent when the computer is turned on and the high temperature required fan speed. And it is worth mentioning that the mechanical and electrical companies Guoping bearing bearing decibel value very low, only ≤ 23dbm, when users are playing games or watching TV, or for the busy work, so a little bit of db They did not disturb the mood, not the kind of disgusting to hear whining sound. Indeed affect the whole body, the fan in this little part of the bearing is your fan product quality is good or bad a determining factor, if there are problems, the entire fan may have been replaced, but this time we will be lost longer a bearing money, but a fan, or even a user confidence in the products.
 Guoping bearing fan electromechanical company's computer containing seven ball bearings, Taper bearing diameter was only just 2mm, diameter 5mm, and its height is 2.5mm, in such a small size contains seven balls, our low-friction bearings self-evident. And we all know, the more the number of ball bearings ability to resist the pressure the higher the quality of the best naturally. We bearings cage is A3HG2, more advanced types of lipid LY121, grease quantity 2.5 ~ 4.5 (mg), has good lubrication. Radial clearance is used in standard grade (3 ~ 8μ), to meet the basic requirements. Perhaps these For you, too abstract, you want to know the quality of this bearing is good, that is, the so-called quality of life, that such a product installed on your fan, the user can use for how long. Then you can be assured that our bearing life> 100,000 hours, one hundred thousand hours is a concept, which means that if you use your computer for up to ten hours one day, then you can also use at least 10,000 days, which is 30 years

How to look at a quality KOYO bearings

KOYO bearing surface contact fatigue failure modes, abrasive wear, adhesive wear and corrosive wear, they always occur in KOYO bearing surface and a surface layer, the surface layer is obviously the quality of the work KOYO the reliability and service life of the bearing vital.
   KOYO bearing surface quality studies include: surface topography analysis; surface material and surface modification layer analysis; surface stress state analysis; surface state of wear and corrosion state analysis and so on.
   Due to cold, heat processing conditions and other factors lubricating medium, KOYO bearing surface microstructure, physical, chemical and mechanical properties and their hearts are often very different from the Ministry. KOYO bearing surface microstructure, physical, chemical and mechanical properties of the surface layer changes called surface modification layer. If the surface is altered layer caused by the grinding process is called grinding surface metamorphic layer. KOYO bearing surface KOYO bearing metamorphic layer surface quality analysis is the main component analysis, of course, KOYO bearing failure analysis is one important part.
   A first look at the use of bearing steel material, Japan KOYO bearings is their own professional steelworks produced, both in terms of hardness and precision than fake KOYO bearings.
2 marking equipment with high inputs, in order to establish a brand image, prevent product counterfeiting, KOYO bearings manufacturers use a laser marking machine, hoping to establish a corporate image, with international standards at the same time, with the high input to control the products are fake, however, Since using a computer controlled laser marking machine, marking the font, size and other advantages of easy editing, not only can effectively prevent counterfeiting, but to increase the difficulty of counterfeiters.
Three observation. With the naked eye rolling KOYO bearings, inner and outer raceway spalling should be no traces and severe wear, and was an arc-shaped groove; all rolling surface should be no spots, cracks and peeling phenomenon; cage should not be loose, no damage, not worn out, but the big gap with the rolling elements.
4 hand method. Normal KOYO Taper bearing inner and outer races and rolling gap of 0.005 to 0.010 mm. Have used a stage for rolling KOYO bearings, inner ring with your fingers axial shaking, there should be no obvious clattering.
5 Turn the Act. With one hand holding KOYO bearing inner race, the other hand turning outer race, KOYO bearings should be flexible rotation, and should not feel the radial shaking.
6 Of course, the price depends on the price is much lower than normal if there might be a fake recommended not to buy, after all, really, after all, you pay for the high cost of imports so expensive.

Deep groove ball bearings

Deep groove ball Taper bearing imported bearings are mainly used for pure radial load, but also to support radial load and axial load. When the only pure radial load, the contact angle is zero. When the deep groove ball bearings with a larger radial clearance, the performance with angular contact bearings can bear large axial load. Deep groove ball bearing friction coefficient is small, limit speed is also high, especially in very high speed axial loading conditions, deep groove ball bearings Thrust ball bearings are more advantages. Deep groove ball bearings are the most representative of rolling bearings, widely used.
Deep groove ball bearings in the structure of each ring has a cross-section of the equatorial circumference of the ball one-third of the continuous groove type raceway. Deep groove ball bearings are mainly used to bear radial load, but also bear certain axial load. When the bearing radial clearance increases, with the nature of angular contact ball bearings, can withstand both directions alternating axial load. With the same size compared to other types of bearings, such bearings friction, high limiting speed, high precision, user selection is the preferred bearing type. Deep groove ball bearing structure is simple, easy to use, is the largest production volume, most widely used of a class of bearings.
For high speed or high speed operation, and very durable, without regular maintenance. This kind of bearing friction, high limiting speed, simple structure, low cost, easy to achieve high manufacturing precision. Size range and diverse, used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries, the machinery industry, the most widely used class of bearings. Main radial load, but also can withstand a certain amount of axial load deep groove ball bearings can be used for transmission, instrumentation, electrical, household appliances, internal combustion engines, transport vehicles, agricultural machinery, construction machinery, engineering machinery, etc.
Select a larger radial clearance axial Slewing bearing capacity increases, pure radial force, the contact angle is zero. Axial force, the contact angle is greater than zero. Commonly used stamping Ribbon Cage, machined solid cage, sometimes with nylon frame.
Deep groove ball bearings mounted on the shaft, the axial bearing clearance range, shell limit the axis or axial displacement in both directions, it can be in the bi-axial positioning. In addition, the class also have some bearing self-aligning capability, when compared to shell-hole tilt 2 'to 10', still work, but have a certain influence on bearing life. Deep groove ball bearing cage mostly steel stamping Ribbon Cage, a large multi-use vehicles bearing metal solid cage

LYTBZ can also supply the pressure plate.

Thrust tapered roller Taper bearing structure, performance characteristics
Since thrust tapered roller bearings rolling body is tapered roller, rolling in the structure of the bus and the raceway washers are bus lines intersect at a point in the axis of the bearing, which can form pure rolling rolling surface, speed limit higher thrust cylindrical roller bearings.
Thrust tapered roller bearings can withstand a one-way axial load. Thrust tapered roller bearing type code 90000.
Since thrust tapered roller bearing production is less, the plant has produced models are mostly nonstandard dimensions, while the standard dimensions of the series, varieties produce less, and therefore these bearings is currently no national standards promulgated dimensionsScrew-down bearings - Thrust Tapered Roller Bearings
Third, this type of thrust tapered roller bearings must be able to withstand enormous axial load, and allows the threaded shaft angular displacement relative to the support. Therefore, these bearings usually full roller type, with large diameter and long rollers. In order to withstand the roll offset in the bearing housing on the bearing not adversely affect the performance of this bearing has a spherical seat. The seat can be a shaft or backing bearings seat box seat.
In the spherical shaft seat and the corresponding concave spherical threaded shaft or pressure roller between the baffle set above a spherical seat of the bearing axis, will produce the necessary right of offset. LYTBZ can also supply the pressure plate.
Spherical bearing box seat when the offset from the bearing housing on the seat between the baffle and the pressure roller groups to bear. This bearing pressure plate is usually supplied with the same bearing.
LYTBZ produce a variety of designs screw bearings; This bearing is customized to meet the special requirements of a particular application

Contact ball slewing bearing failure of the three criteria

 Contact ball slewing bearing well-known sales, quality, quality are the highest in the world, has its professional production line, through a rigorous factory testing procedure, sold around the world, for the world to support industrial development. Contact ball slewing bearing quality to win market acceptance of its most important basis, then to determine from what contact ball slewing bearing quality it?
The selection of a tapered bearing  manufacturer is not qualified bearing failure is a factor that must be considered, in the usual contact ball slewing bearing failure detection is mainly based on a lot of material, data analysis, failure environment, forging process, identify turning supporting contact ball bearing failure of the main factors, and to get rid facilitate contact ball bearing slewing continuous optimization, service life, and performance improved. Prolonged contact ball slewing bearing service period, to avoid the occurrence of unexpected early bearing failure. Installation conditions are the primary factors that one of the factors, slewing ring contact ball bearing is often caused by improper installation package contact ball slewing bearing between the various parts of the stress state changes, contact ball slewing ring bearings in the unusual state operation and early failure. According contact ball slewing bearing installation, use, maintenance, maintenance of the technical requirements for operation of the bearings to bear the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal immediately find out the reasons, adjusted to normal.
Second bearing industrial design reasonable and perfect a world-class, strong quality assurance of its service life. Contact ball slewing bearing forging go through rigorous forging, bearing heat, turning, grinding and bearing equipment such as a road rigorous process, a variety of manufacturing processes will affect the bearing life. Which affect the finished slewing contact ball bearings imported bearings quality, are in contact with the ball slewing bearing failures are directly related. As technology continues to progress detect contact ball slewing bearing surface inspection found that the metamorphic layer grinding process is the fish contact ball slewing bearing surface quality of a close relationship.
3rd contact ball slewing bearings used in the manufacture of metal lottery, once the impact of bearing failure is a major factor, now with the metallurgical technology continues to progress, raw materials extraction has been very good to improve the material quality has greatly improved, and now The raw material quality factors in bearing failure which has been significantly decreased, at this stage the problem still exists.

In the following cases

Slewing tapered bearing fault repair method
Construction Machinery slewing material porosity due or mezzanine, swim raceway hardened layer hardness, depth manufacturing quality problems such as uneven or

Some external reasons, resulting in hardened raceway spalling or broken tooth ring gear, equipment will not work.
For raceway delamination, we must first make the right judgments. Delamination occurs, generally the external hard to see. According to our experience,

In the following cases, indicating that there is delamination raceway: Host load rotates, the raceway has "slightly - slightly" abnormal sound, rotation speed

Uneven or an azimuth slowed significantly and accompanied by a slight vibration; rotary current motor temperature is too high or too large; Rotary

Motor and hydraulic coupling or coupling pushed up bad habits such as keyways.
Delamination occurs, it must be repaired. Otherwise delamination area will be expanded to the entire slewing bearing scrap.
Repair method is: first slewing roller or ball inside out, so that separation of inner and outer rings; reuse gasoline to clean raceway

Clean; Then grinder (wheel) Microsoft Corporation needle carefully peel layer surrounding area has been hardened cracks generated

Layer rubbed off, the bottom layer will peel polished; raceway required for welding and cutting torch at the preheated by using carbon steel welding rod (electrode before

Be dried and used as baking), to make the solder layer just above the raceway surface 1-2mm; deeper if delamination or larger, should be divided

Layer fragmentation welding, do not make the base material caused by high temperature deformation; This avoids rapid cooling weld cracking, immediately after welding

Insulation measures taken so that he gradually cooled. After cooling grinder grind welding layer, making it slightly above the raceway surface, oil stone

Metallographic grinding or welding layer gradually emery cloth table it with the normal surface raceway highly consistent with the corresponding original curvature model testing,

Until the qualifying date; clean with gasoline raceway and roller (ball) coated with grease, integrally assembled to complete.
Facilitation by the above method of tower cranes and other equipment slewing ring raceway, after long-term use is working properly.
Swing ring gear teeth broken reason may be that the tooth base material quality cast segment (if trachoma, sandwich and other defects, the teeth

Round bending effect significantly weakened); process of using tooth contact inserts of hard objects such as stones or reinforced, so that local bending tooth

Stress increases fracture.
Repair method is a local repair welding or tipped, local welding method is: first damaged parts of the residual matrix crack

Rubbed with a hand wheel, gasoline (oil) clean; welding torch used in this part of the warm-up, when it reaches a certain temperature, the use of

Carbon steel welding rod damaged areas in the teeth of the toothed push welding prototype, making it higher than the party Tooth 1-2mm; send experienced

Machine repair fitter, in accordance with toothed model testing, until tooth compliance requirement.
When the rotary ring gear of an entire tooth is damaged, cut along the tooth root, tooth root and then file into a certain shape. Again in the same

Waste storage ring gear cut a tooth, processed into the appropriate shape with the base material, into the slot, with the tooth template snaps into place.

In order to ensure the consistency of pitch, and added with double wire clamp after tightening the teeth surrounded by low-carbon steel welding. Finally, rasp and other working

Shuhei with the welds to ensure stability augmentation to tooth contact.

angle greater carrying capacity. These bearings are separable bearings

Tapered roller bearings use
Tapered roller Taper bearing mainly bear radial diameter and axial joint load. Load bearing capacity depends on the outer ring raceway angle, angle greater carrying capacity. These bearings are separable bearings, rolling bearing according to the number of rows into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance to be adjusted during installation the user; double row and four row tapered roller bearing clearance in the factory according to user requirements is given, not to be user adjusted. Tapered roller bearings have tapered inner and outer ring raceway, Tapered Roller arranged in between. All conical surface projection lines are the same point on the bearing axis together. This design makes tapered roller bearings particularly suitable for combined (radial and axial) loads. Most of the axial load bearing capacity is determined by the contact angle α; α angle increases, the higher the axial load capacity. Angle size calculation factor e; e larger the contact angle the greater the bearing axial load greater applicability. Tapered roller bearings are usually separated type, namely the belt roller and cage assembly of inner components can be composed with tapered conical outer inner (outer) installed separately. Tapered roller bearings are widely used in automotive, mill, mining, metallurgy, plastics machinery and other industries
