Stress Analysis of Tapered Roller Bearings

Tapered roller bearings for radial load, axial load and radial and axial joint load. Tapered roller bearing axial load capacity depends on the contact angle α, that is, the outer ring raceway angle, the greater the contact angle α, the greater the axial load capacity. Tapered roller bearings are generally not allowed angle error, but the roller and the raceway surface after special design allows a 2 'to 4' angle error. Single row tapered roller bearings single row tapered roller bearings can withstand a direction of axial load.

And to restrict the bearing axis relative to a direction of the axial displacement. Even in a pure radial load is applied, tapered roller bearings inside will produce additional axial force component, this time, a need to have an equal amount of force to reverse with the balance. Usually in two single row tapered roller bearing in two identical structures bearing face to face or back to back relative safety in order to ensure good operating condition bearing, tapered roller bearings with other ball bearings and roller bearings, must exert a certain amount of minimum load, particularly the work of the high-speed, high acceleration, or frequent changes in the direction of load conditions.
