Introduction: double row bearing structure characteristics - bearing knowledge in tandem type

'The ball roller bearing of the invention is based on the idea of a genius, it is a new kind of roller and a new method of assembling combination. All do not bear the load of the traditional rolling ball part of the 'ball' has been removed. This means that on both sides of the ball diameter is removed by 15%. The result is known as the ball roller, a flat on both sides of the ball, narrow 30% than the real ball. This significantly saves valuable space. In addition, this kind of special 'thin' shape of roller and the development of special assembly method, can increase the number of roller, to about 90% of the fill the space. In the same space more rolling body can achieve higher rated load, so as to realize a longer service life of products. It also provides a new opportunity to decrease the size of the product and assembly. Double cage design can realize the best two raceway independent adjustment, and an exact match with application. It's guaranteed to the smallest bearing size and lower friction for maximum load support. Rolling bearing in motion due to the resistance bearing wear and failure, grease, Oil) And the different methods of lubrication, to reduce the bearing friction and wear effect is different. Therefore lubrication technology has become an important part of bearing technology research. Someone put grease ( Oil) The fifth part is referred to as 'bearing' ( Other for inner ring and outer ring, rolling element and cage) 。 Hinder the rolling bearing rotating friction resistance by the rolling friction, sliding friction and lubricant. When the roller rolling on the rolling rolling friction occurs; Sliding friction in the cage of rolling element and cage guide surface guard guide surface and roller bearing in the roller end face and ring on the rim. The lubricant friction is the responsibility of the lubricant in the contact of internal friction and lubricant of mixing and extrusion. A set of bearing friction is always rolling friction, sliding friction and lubricant friction resistance is the sum of the impedance bearing movement. Research different grease lubrication technology's mission is to develop, Oil) Least resistance and lubrication method, make its bearing, life expectancy. Of common conditions of bearing grease ( Oil) , foreign advanced industrial countries has completely passed on technology and production, has formed a series of varieties and batch production capacity, the current main trend is the study of improve the performance of some special cases, grease, such as working on improving the space with the vacuum stability of the fluorinated ether grease, climbing move and viscosity-temperature properties, etc. ; And as low fat, although has a good effect in application, but its lubrication mechanism has not been able to have very good theory in this paper. Such as, research in the high temperature ( 200 ~ 4000 degrees) Using gas lubricant, etc.
