It is important to analysis the tapered bearing force?

3,288 Published by Apr 22,2022

tapered bearings are suitable for bearing radial loads, unidirectional axial loads and combined radial and axial loads. The axial load capacity of the tapered bearing depends on the contact angle α, that is, the angle of the outer ring raceway. The larger the contact angle α, the greater the axial load capacity. Generally, tapered roller bearings are not allowed to have angular error, but the surface of the roller and raceway can be allowed to have an angular error of 2' to 4' after special design. Single row tapered bearing can withstand axial loads in one direction.

And can limit the axial displacement of the shaft relative to the bearing seat in one direction. Even under the action of pure radial load, additional axial component force will be generated inside the tapered bearing. At this time, an equal amount of reverse force is required to balance it. Usually two single-row tapered roller bearings of the same structure are used in the two supports face to face or back to back. In order to ensure the good running state of the bearing, the tapered bearing, like other ball and roller bearings, must apply a certain amount of minimum load. , especially for high speed, high acceleration, or work under conditions with frequent changes in load direction.

Because, under these working conditions, the inertial force of the rollers and cages and the friction in the lubricant will adversely affect the rolling and rotation accuracy of the bearing, and there may be sliding between the rollers and the raceway that is harmful to the bearing. sports. The minimum load Fmin required for a tapered roller bearing can be estimated by the following formula: Fmin = 0.02C, where C - basic dynamic load rating, a larger load may be required for start-up at low temperature or in the case of high lubricant viscosity minimum load. Often, the weight of the bearing support itself, plus the load on the bearing, exceeds the minimum required load. If the minimum load has not been reached, this type of bearing must be subjected to additional radial load, such as axial preload on the bearing to meet the minimum load requirements.

In the use of each product, we are most concerned about the core value of such products and the various factors that affect this core value. For tapered bearing, its use efficiency is greatly affected by its force. Therefore, it is very important for the force analysis of tapered roller bearings.
