Embodiment Construction

[0054] It can be seen from the background art that under the action of axial force, the service life of the bearing will be greatly affected.

[0055] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a bearing assembly.

[0056] As shown in the figure, the bearing assembly includes bearing housing 11, roller bearing 12 and bearing outer ring 121 of rotating shaft 13 installed in bearing housing 11, rotating shaft 13 is inserted into bearing inner ring 123, bearing inner ring 123 and bearing outer ring Rolling elements 122 are arranged between 121 .

[0057] For the convenience of description, the bearing inner ring 123 follows the direction of the rotating shaft 13 below figure 1 Take the middle left movement, that is, the movement in the direction of the arrow A in the figure as an example, to explain the working process.

[0058] During the working process, under the action of axial force, the bearing inner ring 123 moves axially with the rotat...

Abstract

Embodiments of the invention provide a bearing assembly and a roller bearing thereof. The roller bearing comprises a fixed bearing ring comprises a first fixed bearing ring portion and a second fixedbearing ring portion which are arranged coaxially, and a rotating bearing ring coaxially arranged with the fixed bearing ring, wherein the first fixed bearing ring portion and the second fixed bearingring portion are same in radial dimension; an axial gap is formed between the first fixed bearing ring portion and the second fixed bearing ring portion; the axial gap is greater than or equal to half of the axial backlash of the roller bearing; and the rotating bearing ring is mounted inside or outside the fixed bearing ring in a sleeved or sleeving mode. According to the bearing assembly and the roller bearing thereof which are provided by the embodiments of the invention, the influence on the service life of the bearing under the action of axial force can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of mechanical equipment, in particular to a bearing assembly and a roller bearing thereof. Background technique [0002] Bearing is a commonly used structure between rotating parts to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. [0003] Roller bearing is a kind of bearing commonly used at present, including bearing outer ring, bearing inner ring, cage and rolling body, rolling body is located between bearing inner ring and bearing outer ring, cage, bearing inner ring and bearing outer ring are common Determine the position of the rolling element. When connecting the bearing with other components, the outer ring of the bearing is installed in the bearing seat, and the inner ring of the bearing is connected with the shaft. [0004] Under normal working conditions, the bearing mainly bears radial force and its own...
