Improve the practical method of fitting accuracy

In order to improve the bearing with precision the actual installation, you must not make use of the Tapered bearing deformation measurement methods and measuring tools, bearings and cylindrical bore size of the mating surfaces of the actual precision measurement can be measured on the inner and outer diameters All items to be measured, and the measured data to make a comprehensive analysis of this as far and precision worthy of shaft and housing bore Stainless steel slewing bearing mounting portion size. In actual measurements made ??with the respective shaft and housing bore size and geometry should be the same with the measuring bearing temperature conditions.

To ensure the effect of a higher actual mating shaft and the bearing bore to match the surface, the roughness should be as small as possible.

In making these measurements, should be cylindrical and the bearing bore, the housing bore and the shaft, and a corresponding surface of the chamfered sides near the assembly, respectively, showing the maximum deviation to make the direction of two marks, so that in actual assembly, the mating alignment of both the maximum deviation of the same position, so that after assembly, the two sides can be partially offset by the deviation.

Directional signs made ??two aims can compensate for deviations into account, even if both sides supporting each rotation accuracy improved, but also between the two bearing seat hole and both ends of the journal concentricity error partially eliminated. Surface hardening on the mating surfaces to implement measures, such as sandblasting, with a diameter slightly larger than the precision plunger plug holes, once inside, there is help to improve the fitting accuracy.

How to prolong the service life of bearings?

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 bearings 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 Stainless steel slewing bearing 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.

Bearing meaning

ID Code: Under normal circumstances bearing diameter bearing inner code (the basic code of the last two digits) × 5 = internal diameter (mm), Example: 6204 bearing diameter is 04 × 5 = 20mm.
Common special cases:
(I) When the bearing diameter less than 20mm
Bearing diameter size (mm) 10 12 15 17
Corresponding inner code is 00010203
(Ii) When the bearing diameter less than 10mm, the direct use of the basic code of the last one represents the bearing bore size; Example: Bearing 608Z, with a basic code '608 'as the last one eight inner diameter, the inner diameter of the bearing 608Z 8mm. An inner diameter of 627 so 7mm, 634 an inner diameter of 4mm.
(Iii) the bearing bore is not a multiple of 5 is equal to or greater than 500mm, diameter code with a slash '/' character. Another situation: There are some old code needle Stainless steel slewing bearing  iameter code directly using the '/' character. These types of situations '/' behind several values ​​for the bearing bore size. Example below:
Bearing 619/1.5 62/22 60/5003519/11207943/25
Diameter size (mm) 1.5 22 500 1120 25
These are some of the common representation bearing bore, some of the international code of the company are not all the same; should to the actual situation. Specifically to refer to a variety of materials and samples of each manufacturer.
Size code: for expressing the same diameter but the diameter and width of the bearing, see Fig.
Diameter Code ↑
↑

Width Code
OD Series Code: special light (0,1), light (2), middle (3), weight (4)
Width series code: normal width to "0", usually not marked. But for tapered roller bearings (Class 7) and self-aligning roller bearings (3 classes) and other types can not omit the "0"
6010 is slim series, used in light load, high speed; 6210 series is a lightweight, light load speed most reasonable, is the application of the most extensive type; 6310 is the heavy series; 6410 series is re-used for heavy low. Medium and heavy duty most widely used, such as various types of mechanical transmission components, small motors, conveyor lines, motorcycles, etc. Almost all the machinery and equipment used in both types.
Type code: should be remembered that the commonly used bearing code: 3,5,6,7, N 5, corresponding to the old code 7,8,0,6,2 classes. .
Tolerance class code table:
Radial bearings and angular contact ball bearings are divided into five below (High → Low)
New level code P2 P4 P5 P6 P0
Old level code B C D E G
Tapered roller bearings are divided into four below (High → Low)
New level code P4 P5 P6x P0
Old level code C D Ex G (E)
Thrust ball bearings are divided into four below (High → Low)

SKF executives of leading enterprises of Chinese fans

Recently, in 2010 during the International Wind Energy Conference, SKF global renewable energy sector, Mr. Stefan Karlsson responsible person to accept an interview with reporters and fans on Chinese enterprises into the development status, and published a point of view.

      Here is SKF's exclusive distributor in China reported, according to officials Stefan Karlsson SKF introduced similar Sinovel, Goldwind and other Chinese domestic wind turbine equipment leading enterprises, has reached more advanced international level of manufacturing wind turbines. Currently there are about 80 local Chinese wind power generators around the manufacturer, SKF have partnerships with most of them.

      Mr Stefan Karlsson SKF executives of leading enterprises of Chinese fans, said: "Although China has reached international advanced level leading wind turbine, wind turbines have several years of operating experience, to go through the test of time in the long run, fans of quality problems is the relationship between the nature of the final cost of the problem. domestic wind turbine manufacturer in the measure of costs have a feature often easier to consider only wind turbine manufacturing costs, but it ignores some important aspects, that is, wind power machine throughout its life cycle subsequent running costs in the Chinese market, SKF's main competitors or those who have international background of the imported bearings manufacturers for the domestic wind turbine manufacturers, they are more willing to choose some meet international quality standards. "

      SKF already has five technology platforms (bearings and units, seals, lubrication systems, mechatronics and services) of the product, this time, SKF Group to bring its quiet operation of wind turbine bearing, separable high bearing cylindrical roller Stainless steel slewing bearing and WindLub centralized automatic lubrication system unveiled three new new State Fair.

Destroyed 26 tons of counterfeit bearings Schaeffler

Accompanied by a loud noise, excavator clamp arm to all types and sizes of rolling into the waste punch. Bearing in punch was cut into pieces or severely damaged and become unusable. Too large to fit into scrap punch, the diameter of which exceeds 1 meter large Stainless steel slewing bearing were destroyed through the torch. All of these bearings are confiscated in raids with INA and FAG brand logo counterfeit products. The purpose of this action is to make these backing bearings can no longer be used.In 2007 the first public display of destruction operations, about 40 tons of counterfeit bearings Schaeffler company is located in Schweinfurt be destroyed, but there are many other global destruction of counterfeit goods operations. In that action after this there are about 26 tons, valued at over one million euros of counterfeit bearings in Schweinfurt INTERSEROH Franken Rohstoff limited liability company's office premises were destroyed. A large proportion of counterfeit products come from the European raids bearing distributors, such as Italy and the UK dealers. But there are some fake bearings from Germany. "The phenomenon of counterfeit brands and products not only confined to the Chinese and South-Eastern Europe, it also occurs in our doorstep." Schaeffler Global Brand Protection team leader Ingrid Bichelmeir-B hn said. "German and European markets are not just flooded with counterfeit luxury goods or consumer goods, industrial safety-related counterfeit products, such as bearings, is also increasing."This operation scrapped spindle bearings, spherical roller bearings, ball bearings and needle roller bearings just confiscated counterfeit products in part Most of the countries under the supervision of local authorities have been dealt with.Schaeffler has been traced on a global scale and distribution of counterfeit bearings, and may in some cases litigation. Not only under civil law to stop order or damage or destruction of counterfeit products turned over claims threat, but also under criminal law with fines and imprisonment if necessary, the threat of prosecution. Economic losses caused by counterfeit products is difficult to measure. In addition to the loss of revenue due to low-quality merchandise and caused damage to the company's image, bearing the investigation, confiscation and proper disposal will lead to high costs.
Not only is the production of branded products and conduct complex research, development and quality assurance of the company has been lost, the installation of counterfeit parts companies and their customers will suffer. Switzerland, a recent case once again proved that when the bearing as a safety-related parts used in machinery and equipment, its failure would cause significant losses. As a customer complaint a Swiss company, making the machine repaired installed a cylindrical roller bearing fake events became clear. Despite regular maintenance, the machine is still in just six months after the occurrence of the thermal operation. Although the client to discover an exception, but still resulted in about 17,000 euros maintenance fee that exceeds many times the value of the bearing.

The use of cross roller bearing characteristics

1, with excellent rotational accuracy
Crossed roller Stainless steel slewing bearing internal structure of the roller at 90 ° to each other are arranged perpendicular to the cross, with spacing between the roller cage or spacers to prevent tilting cargo roller mill roller between the police, effectively preventing the rotation torque increase.
2, the operation simplifies installation
Is divided into two parts of outer or inner ring, rollers and loading the holder after being fixed together, so that the installation operation is very simple.
3, bear large axial and radial loads
Because roller at 90 ° to the V-shaped groove raceway via a spacer retainer is arranged perpendicular to each other, this design makes cross roller bearings can withstand greater radial load, axial load and moment load and all the direction of the load.
4, significant savings in installation space
Cross roller bearing outer ring size is minimal miniaturization, especially thin structure is close to the limit of small size, and high rigidity.
 Roller bearing is cylindrical, conical or drum-shaped roller for rolling element bearing. Roller bearings are mainly radial cylindrical roller, double row spherical roller, tapered roller and thrust roller and structure type.
 In recent years, we use CAD, PDM and other product design aids and ERP, CRM and other management systems, and continuously improve the quality and efficiency of our work, engineering and technical personnel working days in half to provide users a preliminary design solution that can at any time user to solve various problems; while sales engineers fastest we can within one hour of the global user inquire the price of conventional products to make accurate reply. We always keep this efficient work efficiency, meet or exceed the expectations of users, for users worldwide to provide comprehensive, systematic and efficient service.

Rolling classification introduced

A. Press the bearing structure type classification
(1) can bear the load bearing according to the direction or different nominal contact angle, divided into:
A) radial bearings ---- mainly used to bear radial load bearing, its nominal contact angle from 0 to 45. At different nominal contact angle, is divided into: radial contact bearings ---- nominal contact angle of 0 radial bearings: Radial angular contact bearings ---- nominal contact angle greater than 0-45 of radial bearings.
2) ---- thrust bearing is mainly used for axial load bearing, its nominal contact angle greater than 45-90. Press the nominal contact angle is divided into different: axial contact Slewing bearing ---- nominal contact angle of 90 thrust bearings: Axial angular contact bearings ---- nominal contact angle greater than 45 but less than 90 of the thrust bearing.
(2) The rolling bearing according to the types, divided into:
1) Ball Bearing ---- the ball rolling:
2) Roller Bearing ---- rolling as rollers. Roller Bearing press roller types are divided into: cylindrical roller bearings ---- rolling body is cylindrical roller bearings, cylindrical roller length to diameter ratio of less than or equal to 3; needle bearing ---- rolling body is a needle roller bearings, needle length to diameter ratio greater than 3, but the diameter is less than or equal to 5mm; tapered roller bearings ---- rolling body is tapered roller bearings; aligning roller bearings eleven rolling body is spherical roller bearings.
(3) whether the bearing aligning their work, divided into:
A) aligning bearing ---- raceway is spherical in shape, able to adapt to two raceways angular misalignment between the axis line and angular movement of the bearing.
2) Non-aligning bearing (rigid bearing) ---- can impedance raceway of the bearing axis line angle offset.
(4) rolling bearing according to the number of columns, divided into:
1) having a single bearing ---- rolling bearing.
2) ---- double row Stainless steel slewing bearing with two rows of rolling elements bearings.
3) multi-row bearings ---- with more than two rolling element bearings, such as three, four bearings.
(5) bearing their parts can detach, divided into:
1) Bearing ---- separable bearings with separable components;
2) non-separable bearings ---- bearings in the final package, the ring can not be separated any free bearings.
(6) bearing their structural shapes (eg with or without filling slot, with or without inner and outer rings and rings shape, wall structure, even without the cage, etc.) can also be divided into a variety of structural types.
B. By rolling bearing according to their size diameter size classification, divided into:
(1) miniature bearings ---- nominal diameter size range of 26mm below the bearings.
(2) small bearings ---- nominal diameter size range of 28-55mm bearings.
(3) small bearings ---- nominal diameter size range of 60-115mm bearings.
(4) the large bearing ---- nominal diameter size range of 120-190mm bearings.
(5) large bearing ---- nominal diameter size range of 200-430mm bearings.
(6) large bearings ---- nominal diameter size range of 440mm or more bearings.
