Problems solved by technology

The use of bearings is very common. In order to fix the bearings on the inner surface of the installation and prevent the bearings from coming out from both sides, some complicated positioning structures are often designed on both sides of the installation, which makes the structure of the product complicated and inconvenient. Installation, while the balls in the bearings are severely worn due to friction

Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, a bearing axial fixing device includes a bearing 1 , a mounting body 2 , an upper mounting hole 3 , a loading and unloading hole 4 , a sleeve 5 , a spring 6 , and a lower mounting hole 7 . The outer surface of the bearing 1 is provided with a lower installation hole 7; the inner surface of the installation body 2 is provided with an upper installation hole 3; the installation body 2 is set on the outer surface of the bearing 1. The sleeve 5 has a cylindrical structure and is sleeved on one end of the spring 6 . The spring 6 is a cylindrical spring, which matches the inner hole of the sleeve 5 . The axial height of the sleeve 5 is 1-2 mm smaller than the length of the lower mounting hole 7 . The length of the spring 6 in a natural state is 3-5 mm larger than the length of the lower mounting hole 7 .

Abstract

The invention relates to a bearing axial fixing device. The fixing device comprises a bearing, a mounting body, an upper mounting hole, a loading / unloading hole, a sleeve, a spring and a lower mounting hole; the lower mounting hole is formed in the outer surface of the bearing; the upper mounting hole is formed in the inner surface of the mounting body; the mounting body coats the outer surface of the bearing; the sleeve is a cylindrical structure, and coats one end of the spring; the spring is a cylindrical spring, and is matched with an inner hole of the sleeve; the loading / unloading hole is formed in the corresponding position of the outer surface of the mounting body, and is communicated with the upper mounting hole; the axial height of the sleeve is smaller than the length of the lower mounting hole by 1-2 mm; and the length of the spring in the natural state is longer than the length of the lower mounting hole by 3-5 mm. The fixing device is designed by technicians according to problems generated in actual use of the bearing, is simple in structure and convenient for use, can be widely applied to bearings with different types, and solves the problem of axial movement of traditional bearings during working.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, in particular to a bearing axial fixing device. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The use of bearings is very common. In order to fix the bearings on the inner surface of the installation and prevent the bearings from coming out from both sides, some complicated positioning structures are often designed on both sides of the installation, which makes the structure of the product complicated and inconvenient. At the same time, the balls in the bearings are severely worn due to friction. Contents of the invention [0003] The object of the present invention is to provide a bearing fixing device with simple structure, which can reduce axial movement and will not fall out during u...
