Embodiment 1

[0035] This embodiment provides a bearing assembly, such as figure 2 As shown, it includes: a bearing chamber 1 with a housing chamber 11 inside; two sets of bearings 2 relatively fixed at both ends of the housing chamber 11; two groups of elastic members 3 respectively arranged on the inner side of the bearing 2 , the accommodating cavity 11 is provided with a raised portion 4 at least at a position corresponding to the inner end surface of the bearing 2, and the elastic member 3 is arranged between the raised portion 4 and the inner surface of the bearing 2 .

[0036] In this example, if figure 2 As shown, the two groups of bearings 2 located on the left and right sides are respectively arranged at the left and right ends of the accommodation cavity 11 , and the outer end surfaces of the bearings 2 and the outer end surfaces of the bearing chamber 1 are flush with each other. In this embodiment, the bearing 2 is tensioned and arranged on the inner wall of the bearing cha...

Embodiment 2

[0048] This embodiment is made on the basis of Embodiment 1. In this embodiment, another adjustment method of the preload of the elastic member 3 is provided. In this embodiment, the bearings 2 corresponding to one group The length of the protruding portion 4 is greater than the length of the protruding portion 4 corresponding to another set of the bearings 2 .

[0049] Specifically, as Figure 4 and Figure 5 As shown, the length of the raised portion 4 on the left side is longer than the length of the raised portion 4 on the right side. By limiting the length of the raised portion 4, the support force that the inner side of the bearing 2 can bear can be adjusted. . Generally speaking, when the length of the protruding part 4 is longer, its supporting force on the elastic member 3 is greater, and at this time, the pre-tightening force that the elastic member 3 itself can provide is also greater. By controlling the length of the protruding portion 4, it is possible to well ...

Abstract

The invention provides a bearing assembly. The bearing assembly comprises a bearing chamber, two groups of bearings and two groups of elastic pieces, wherein an accommodating cavity is formed inside the bearing chamber; the two groups of bearings are oppositely fixed at the two ends of the accommodating cavity; the two groups of elastic pieces are respectively arranged in positions of the inner side surfaces of the bearings; a protruding part is arranged in the position, at least corresponding to the inner end surface of each bearing, of the accommodating cavity; and the elastic pieces are arranged between the protruding parts and the inner side surfaces of the bears. According to the bearing assembly, through the cooperation of the elastic pieces and the protruding parts, and by adjusting the magnitude of the elastic force of the elastic pieces pre se, when one group of bearings in the two groups bear strong force, the bearing capacity of the bearings in the position can be increased by increasing the elastic force of the elastic piece corresponding to the position of the bearings; the service life of the bearing in the corresponding position can be prolonged; and noise caused by uneven stress of the two groups of bearings can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing assembly. Background technique [0002] The bearing assembly is widely used in various transmission structures, and the frictional force on the rotating shaft during the rotation process can be effectively reduced by arranging the bearing assembly. [0003] Bearing assemblies include single bearing assemblies and double (multiple) bearing assemblies, for traditional double bearing assemblies, such as figure 1 As shown, the two bearings are not connected by any parts, that is, there is no preload between the two bearings. [0004] For the dual-bearing assembly provided in the prior art, when the two bearings are subjected to different loads during operation, if the two bearing assemblies are subjected to the same preload, it is easy to cause the bearing with a larger load to fail and affect the overall bearing. life, increased noise. Contents of the invention [00...
