The purpose of tapered roller bearings
Tapered roller bearings mainly bear radial and axial combined loads. Bearing capacity depends on the raceway angle of the outer race, the greater the angle, the greater the load capacity. This kind of bearing belongs to separate type bearing. According to the number of rolling elements in the bearing, it can be divided into single row, double row and four row tapered roller bearings. The clearance of single row tapered roller bearings needs to be adjusted by the user during installation. The clearance of double row and four row tapered roller bearings has been given according to the user's requirement when the product is out of the factory, and need not be adjusted by the user.
Tapered roller bearings have a conical inner ring and an outer race raceway, and tapered rollers are arranged between them. The projection lines of all conical surfaces are gathered at the same point of the bearing axis. This design makes tapered roller bearings particularly suitable for compound (radial and axial) loads. The axial load capacity of bearings is mostly determined by the contact angle alpha. The larger the angle alpha, the higher the axial load capacity. The angle is expressed by the calculation coefficient E. The greater the e value, the greater the contact angle, the greater the applicability of bearing to bear the axial load.
Tapered roller bearings are usually separated, which means the conical inner ring assembly composed of the inner ring with roller and cage assembly can be installed separately from the conical outer ring (outer ring).
