Sectional Shape Structure Of Spherical Roller Bearing

wallpapers Robot Tech 2021-01-15
Spherical roller bearings are bearings with drum-shaped rollers assembled between the inner ring with two raceways and the outer ring with spherical raceways.
 
Spherical roller bearings are divided into two different structures: symmetrical spherical rollers and asymmetrical spherical rollers according to the cross-sectional shape of the rollers. Asymmetrical spherical roller bearings are early products, currently mainly for main engine maintenance services, new designs Symmetrical spherical roller bearings are rarely used in the main engine. The internal structure has undergone a comprehensive improvement design and parameter optimization. Compared with the early production of spherical roller bearings, it can withstand greater axial load. This kind of bearing operation The temperature is lower, so it can meet the requirements of higher speed.

 
According to whether the inner ring has ribs and the cage used, it can be divided into two types: C type and CA type. The characteristics of C type bearings are that the inner ring has no ribs and the use of steel plate stamping cages. The characteristics of CA type Terry bearings In order to improve the lubrication of the bearing, a spherical roller bearing with an annular oil groove and three oil holes in the outer ring can be provided to the user. The bearing is rear-mounted. Code /W33 said.
 
According to user requirements, spherical roller bearings with inner ring oil holes can also be supplied. In order to facilitate customers to install, unload and replace bearings, spherical roller bearings with a taper inner hole can also be provided, and the taper hole taper is 1:12 , The post code is K to indicate that, in order to meet the requirements of special users, bearings with an inner hole taper of 1:30 can also be provided. The post code is K30. Bearings with an inner hole taper can be directly mounted on the taper with a lock nut On the journal, the bearing can also be installed on the cylindrical journal by means of an adapter sleeve or a withdrawal sleeve.
