Bearing assembly and tapered roller bearing

Abstract

The invention provides a bearing assembly and a tapered roller bearing. The tapered roller bearing comprises at least two ranks of tapered rollers, inner circles of the bearing and separating parts, wherein the inner circles of the bearing comprise resisting edge parts and roller path parts; the resisting edge parts are fixed to the first end surfaces of the roller path parts; the separating rings are arranged between adjacent inner circles of the bearings and are in contact with the second end surfaces of the roller path parts; and the tapered rollers are positioned on the outer circumferential surfaces of the roller path parts and are positioned between the resisting edge parts and the separating rings. According to the tapered roller bearing provided in the embodiment, the separating rings and the inner circles of the bearings are two independent parts, so that the tapered roller bearing is convenient to mount and dismount without outer mounting tools, and as a result, abrasion of complex mounting tools to a holding frame in the mounting process can be avoided; in addition, the holding frame is not damaged during dismounting, so that the service life of the holding frame is prolonged, and the cost is saved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of machinery, in particular to a bearing assembly and a tapered roller bearing. Background technique [0002] There are many types of rolling bearings to meet the performance requirements of different application scenarios. Among them, tapered roller bearings are widely used in the fields of freight cars, locomotives and subways, and are mainly used in scenarios that need to bear combined axial and radial loads at the same time . [0003] The small end rib of the bearing inner ring of the double row tapered roller bearing makes it difficult to install the rolling element cage assembly on the inner ring of the bearing, so installation tools must be used. However, the installation tool is likely to cause the cage to be damaged during use. out of shape. Moreover, when the tapered roller bearing is repaired, it is difficult to remove the cage from the inner ring of the bearing. The ca...

Problems solved by technology

[0003] The small end rib of the bearing inner ring of the double row tapered roller bearing makes it difficult to install the rolling element cage assembly on the inner ring of the bearing, so installation tools must be used. However, the installation tool is likely to cause the cage to be damaged during use. out of shape

Moreover, when the tapered roller bearing is repaired, it is difficult to remove the cage from the inner ring of the bearing. The cage must be cut off to take out the inner ring of the bearing, but the cut cage cannot be used any more. Maintenance costs of tapered roller bearings
