Bearing (Bearing) It is a kind of important spare part in contemporary mechanical equipment. Its main function is to support the mechanical solid of revolution, reduces the coefficient of friction (friction coefficient) in its rate process ,And guarantee it turns precision (accuracy) round .

Rub the difference of properties according to the movement component, the bearing can be divided into an antifriction bearing and big class of the sliding bearing two. Among them antifriction bearings have been already canonicalization, seriation, but compare with sliding bearing its radial size, vibration and noise are relatively great, great too of the price.
The antifriction bearing is generally made up of outer lane, inner circle, rolling element and part of retainer four, it is made up of outer lane, inner circle, rolling element, retainer, sealing, major possession of lubricating oil six that it is said that rigorous. To put it briefly, so long as can be defined as the antifriction bearing when possessing outer lane, inner circle, rolling element. According to the shape of the rolling element, the antifriction bearing is divided into ball bearing and roller bearing two big class.

Pay attention to the main point
Guarantee from using the angle the bearing should pay attention to the following several points to work reliably:
1,Improve lubricated quality, control the pressure, temperature and flowrate of the engine oil, strengthen the engine oil to filtrate.
2,It accords with specified fuel and lubricating oil to adopt.
3,Control the temperature state of the diesel generator set, it is all unfavorable to work in with overheated supercooling cases. Leng Tian, the diesel engine should be preheated first before start, and rotated the crankshaft by hand to make the engine oil enter and grit the surface.
4,The bearing, journal surface condition and geometric shape should get the assurance strictly.
5,The bearing clearance should be appropriate, the generating set over assaults, too lubricate badly small, may burn tiles.

The ball bearing of major groove is the most general kind of type in antifriction bearing. The ball bearing of major groove of the basic model has an outer lane, an inner circle, a series of steel balls and a series of retainers that are constructed. The ball bearing type coaxiality of major groove is 6.

The major groove ball bearing is used mainly for bearing the pure radial load, can also bear radial load and axial load at the same time. When it only bears the pure radial load, the contact angle is zero. When ball bearing has the greater radial backlash in the major groove, namely have characteristic that angles are exposed to the bearing, can bear the greater axial load. The coefficient of friction of the ball bearing of major groove is very small, the terminal rotational speed is very high too, especially under the high-speed operation working condition very large in axial load, the major groove ball bearing has superiority even more than the thrust ball bearing.
