Double-row tapered roller bearing capable of bearing non-balance loads

Abstract

The invention relates to the technical field of bearing machining, in particular to a double-row tapered roller bearing capable of bearing non-balance loads. The bearing is of a non-symmetric structure, design parameters of the row A and the row B of the bearing are different, the number of the A row of rollers is larger than the number of the B row of rollers, the length of the A row of rollers is larger than that of the B row of rollers, and the diameter of the A row of rollers is smaller than that of the B row of rollers. The bearing contact stress and bearing rigidity of the A row can be obviously improved, when the bearing bears eccentric loads and overturning moment generated by the non-balance load effect, the bearing can effectively reduce the bearing stress concentration condition, and the service life of the bearing is prolonged. The bearing centre of the bearing is not the centre of the bearing, and therefore the bearing can bear certain eccentric loads and overturning moment, the stress concentrated condition of the bearing is reduced, and the service life of the bearing is prolonged.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a double-row tapered roller bearing capable of bearing unbalanced loads. Background technique [0002] The traditional double-row tapered roller bearing is designed with a symmetrical structure. The load-bearing center of the bearing is at the center of the bearing. When the load-bearing position of the bearing is at the center of the bearing, the bearing is loaded evenly. Under the action of a certain overturning moment, partial load occurs, and the internal load of the bearing will cause stress concentration, resulting in early fatigue of the bearing. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a double-row tapered roller bearing that can bear unbalanced loads. [0004] In order to realize the above-mentioned purpose of the invention, the present invention adopts the following...
