series bearing be used to adjust the circuit parameters control

Using electric force, magnetic force of the shaft suspension sliding bearings. Electric field force is electrostatic series bearing suspension with magnetic force suspension of magnetic bearings (see figure), electric field strength and the magnetic field strength is combined together suspension bearings. A bearing both electrodes have the poles in the circuit connecting the capacitor and inductor corresponding to each other tuner, NNCF series bearing the stiffness is much higher than the first two, and the corresponding displacement of the maximum force is very small. Electromagnetic bearings for shaft and bearing no direct contact, no lubrication, can be in a vacuum and over a wide temperature range, friction is small, not the speed limit, long life, the structure can be diversified. Static bearing requires a lot of field strength, the application is limited, use only a few meter. Magnetic bearings with a larger carrying capacity and stiffness, have been used in ultra high-speed trains, ultra high-speed centrifuges, hydro, spacecraft angular momentum flywheels, flow meters, Tapered bearing density meter, power meter, vacuum pumps, precision current regulator and gyroscopes. With the development of magnetic and electronic technology, electromagnetic bearing applications are growing. Electric force and electric field strength, electric displacement and the electrode area is proportional to the magnetic field strength and the magnetic field strength is proportional to the magnetic flux density and magnetic area. Select the appropriate electric or magnetic field parameters and geometry, slim bearings get some bearing load capacity and stiffness. Electrostatic attraction between the magnetic attraction is inversely proportional to the square or the distance of the object, according to Hugh Aner theorem, series bearing this system is statically indeterminate statics, so in addition to the use of anti-bearing outer magnets or superconductors, in the electrostatic field or static magnetic field work bearing is unstable. For the magnetic bearing is stable, servo device or method must be used to adjust the circuit parameters control. The actual use of the general magnetic bearing by radial bearings, thrust bearings, servo-control loop, dampers, speed sensor or position sensor and other components.

Roller Bearing the pulse energy from the impact analysis

Spherical roller bearing vibration signal analysis and diagnosis by spectral analysis of rolling bearing vibration signal can discover hidden reasons of precision rolling bearing fault diagnosis
1, from the point of view of the frequency
As can be seen for different reasons in different frequency corresponding to the frequency of failure tapered bearing supplier because only a small mounting structure caused when the spherical roller bearing element has manufacturing defects or serious damage to severe vibration frequency will be significantly improved .
2 , the pulse energy from the impact analysis
When the spherical roller bearing elements have tiny little damage pulse value fault with the development of the pulse value increases vibration intensity also increased split roller bearing significantly.
3 , monitoring methods
For the spectrum can be used to determine whether the device is relatively normal criteria
Lubrication time interval has a simple premise : The spherical roller bearings to keep the equipment running without reasonable and crashes due to dry conditions and stop running . This is a fixed concept of prevention . However, we must maintain a balance and a lot of excessive thirst lubrication lubrication between .
Traditionally, the lubrication plan is based on the time given . Equipment suppliers to develop normally lubricated plan based on operating time. And equipment suppliers are often added to the amount of lubricating oil in their maintenance program to guide the process .

use and maintenance repair and other maintenance meets the technical requirements

The main factor is the use of installation and adjustment , use and maintenance  repair and other maintenance meets the technical requirements. According gimbal tapered roller bearing  installation , use, maintenance, maintenance of technical requirements for the operation of the bearings to withstand load, speed , temperature , vibration, noise and lubrication condition monitoring and inspection , abnormal immediately tapered bearing supplier find reasons to adjust to return to normal. Without further need for impact resistance as spherical roller thrust bearing materials using chrome steel , chrome molybdenum steel , nickel-chromium -molybdenum steel , the use of carbon infiltration quenching the steel from the surface to the proper depth of a hardened layer . With appropriate hardening depth , meticulous organization , appropriate surface hardness and core hardness of infiltration of carbon bearings , thrust bearing steel than using spherical roller bearings with excellent impact resistance , the general chemical infiltration of carbon bearing steel ingredients.
