Tapered roller bearings are suitable for bearing radial load, unidirectional axial load and combined radial and axial load. The axial load capacity of tapered roller bearings depends on the contact angle α, Outer race raceway angle, contact angle α The larger the, the greater the axial load capacity. Generally, tapered roller bearings are not allowed to have angle error, but the surface of rollers and raceways can have angle error of 2 ′~ 4 ′ after special design. Single row tapered roller bearing single row tapered roller bearing can bear axial load in one direction.
It can limit the axial displacement of the shaft in one direction relative to the bearing seat. Even under pure radial load, additional axial force will be generated in tapered roller bearing. At this time, an equal amount of reverse force is needed to balance it. Generally, two single row tapered roller bearings with the same structure are installed face-to-face or back-to-back in two supports. In order to ensure good operation of the bearings, tapered roller bearings, like other ball bearings and roller bearings, must apply a certain amount of minimum load, especially for high speed, high acceleration, or under the condition of frequent changes in load direction.
Because of these working conditions, the inertia force of the roller and cage and the friction in the lubricant will have an adverse impact on the rolling and rotation accuracy of the bearing, and there may be harmful sliding movement between the roller and the raceway. The minimum load Fmin required by tapered roller bearing can be estimated by the following formula: Fmin = 0.02c, where C – Basic rated dynamic load. Larger minimum load may be required when starting at low temperature or when the lubricant viscosity is very high. Usually, the weight of the bearing support itself plus the load borne by the bearing has exceeded the minimum load required. If the minimum load has not been reached, additional radial load must be applied to such bearings, such as axial preload, to meet the minimum load requirements.
In the use of each product, we are most concerned about the core value of this kind of product and various factors affecting this core value. For tapered roller bearing, its service efficiency is deeply affected by its stress. Therefore, the bearing force analysis of tapered roller shaft is very important, which is not only the knowledge that users should master, but also a new way for businesses to promote this kind of products.
