FAG Bearings, if there is no wrong choice, the proper use of words, to a flat needle bearing service life before a long period of time on the other hand, there is an accident of early injury, unable to withstand the use of early damage, as the early cause of the damage, enough to consider the use of lubrication, and thus, foreign invasion, the error of the bearing assembly and shaft deflection, shaft and bearing box is not enough and so can be said that these reasons overlap each other more.
A Comparative Study of restrictions in the use of various mechanical design life and a variety of durable bearings, also decided that the FAG bearing size. Tend to think in select FAG bearings, flat needle bearing, grease life in aging, the fatigue life of the grease, abrasion resistance, low noise, adequate study.
When the the O'clock of the FAG bearings ferrule slewing load, such as the use of clearance fit to install, the then the in the of the ferrule in the the in the the rotating the process of of of the plane needle roller bearing of the the co-ordination surface will be peristalsis the phenomenon of occurred, easy to produce to Fretting Wear, and at this time tie in with the surface will appear the burns , cracks and other damage. Therefore, the bearing journal or bore of the ferrule and mechanical components of the rotary load with interference fit.
Bearing parts of the machinery, flat needle bearing in the radial, axial and weeks to the three directions (tangential) fixed positioning of different requirements. Under normal circumstances, the FAG bearing axial fixed axial closed or partly radial tight fit to achieve the institutional support the free side bearings in the axial direction to be fixed in the axial direction to compensate for the body system installation or thermal expansion and contraction the changes in of the the size of the in the the the process of.
1.Bearing accuracy is high, stable and reliable.
2.operate under high temperature, cryogenic and vacuum environments.
3.Complex structure, the requirements of harsh conditions, magnetic interference on the environment, but no other forms of pollution.
4.Friction is small, low power consumption, to achieve ultra-high-speed operation.
5 DC incentive bearings can only be active type (active).
6. The bearings can only support of the permanent magnet-type yes passive type (passive type), while the passive type bearings impossible to Du on the the in the 3 the direction of stable, at least there are the a direction should be adopted the active type.
7.Repulsion type magnetic bearings, magnetic low utilization rate, the structure is more complex suction type, it seldom used.
8 pure electro-magnet-type bearings can only be larger than 5 degrees of freedom control bearings, size, quality and power consumption.
