Abstract
The invention discloses an improvement structure of a bearing end cover, which comprises an end cover body, wherein a step hole in which a bearing is embedded is formed in the end cover body, and a positioning structure for positioning the bearing axially is arranged in the step hole; the positioning structure comprises a step arranged in the step hole, a groove formed on the inner ring wall of the step hole radially and a check ring for a shaft, which is arranged in the groove; one side wall of a bearing outer ring butts against the end face of the step; and the side wall of the check ring for the shaft butts against the other side wall of the bearing outer ring. The improvement structure has a simple structure and is convenient to install, the bearing is assembled in the end cover and is positioned by the check ring for the shaft, so that the problem of axial running of the bearing is solved directly, axial abrasion between the bearing and the end cover is prevented, the service life of the bearing and the end cover is prolonged, and the safety is improved.
Description
Technical field
The present invention relates to bearing (ball) cover, particularly a kind of bearing (ball) cover improves structure.
Background technique
Usually, bearing is through after the axially locating of bearing (ball) cover, and after the long-term rotation of rotating shaft, bearing has bigger axial float, can accelerate the rate of wear of bearing and end cap like this, influences working life, seriously causes security incident.
Summary of the invention
Problem to be solved by this invention just provides a kind of simple and reasonable bearing (ball) cover and improves structure, changes the mounting point of bearing, makes the axially locating of bearing more stable, has weakened axial float, prolongs the working life of bearing and end cap, improves Security.
In order to solve the problems of the technologies described above, the present invention adopts following technological scheme: a kind of bearing (ball) cover improves structure, comprise the end cap body, it is characterized in that: in the end cap body, be provided with the shoulder hole of setting-in bearing, in shoulder hole, be provided with the position structure of axially locating bearing.
Further, described position structure comprises the step that is located in the shoulder hole, radially be located at groove and the shaft block ring that is located in the groove on the shoulder hole internal ring wall, a sidewall of outer race is against on the end face of step, and the sidewall of shaft block ring is against on another sidewall of outer race.
Further, described shoulder hole and end cap body coaxial line.
After adopting technique scheme, the present invention has following advantage: bearing is assemblied in the end cap, behind the shaft block ring location, directly solved the axial float of bearing, avoid the axial wearing and tearing between bearing and the end cap, prolong the working life of bearing and end cap, improve Security.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of an embodiment of the present invention.
Embodiment
The structural representation of an embodiment of the present invention as shown in Figure 1, a kind of bearing (ball) cover improves structure, comprise end cap body 1, in the end cap body, be provided with the shoulder hole 2 of setting-in bearing 3, in shoulder hole, be provided with the position structure of axially locating bearing, described position structure comprises the step 21 that is located in the shoulder hole, radially be located at groove 22 and the shaft block ring 4 that is located in the groove on the shoulder hole internal ring wall, a sidewall of outer race is against on the end face of step, and the sidewall of shaft block ring is against on another sidewall of outer race.
Because the end cap body has with casing required precision is arranged, and therefore shoulder hole and end cap body is coaxially set, and guarantees the assembly precision of bearing and axle, reduce the mutual wearing and tearing when operation of bearing and bearing (ball) cover when assembling.
The present invention is simple in structure, easy for installation, and bearing is assemblied in the end cap, behind the shaft block ring location, has directly solved the axial float of bearing, avoids the axial wearing and tearing between bearing and the end cap, prolongs the working life of bearing and end cap, improves Security.
Except that above preferred embodiment, the present invention also has other mode of execution, and those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
Claims (3)
