The bearing capacity of a tapered roller shaft, such as the direction and position, and the change, can be explained by the general force at work
Because of these working conditions, roller and cage and inertia force the lubricant friction will of rolling bearing, the rotation accuracy of adverse effects, between the roller and the raceway may produce sliding movement on the bearing harmful.The minimum load Fmin for tapered roller bearings can be estimated by the following formula:Fmin = 0.02CTypeC - Basic rated dynamic load, KNStarting at low temperature or the lubricant viscosity is very high, the minimum load may need more. Typically, bearing the weight plus bearing load, has exceeded the minimum load required. If you have not yet reached the minimum load, the bearing must be subjected to additional radial load. As for the bearing applied axial preload, to meet the minimum load requirements
The axial load of single row tapered roller bearings can withstand axial displacement in one direction. And relative bearing can limit shaft in one direction. Even in the pure radial load, internal tapered roller bearings will produce additional axial force, at this time, there is a need to reverse force equal to and usually in equilibrium. Two supported by single row tapered roller bearing two of the same face to face or back to back relative securityIn order to ensure the bearing to obtain good operation state, with the other ball bearings and roller bearings, tapered roller bearings, must exert a certain amount of minimum load, especially for high speed and high acceleration, or frequent changes in the direction of load conditions.
Tapered roller bearings for radial load, axial load and radial and axial loads. The axial load capacity of tapered roller bearings depends on the contact angle, the outer ring raceway angle, the contact angle increases, the axial load capacity is greater.Generally, tapered roller bearings do not allow angular errors, but the roller and raceway surfaces are specially designed to allow for an angle error of 2 'to 4'.
