Abstract
The utility model discloses an improved-structure bearing end cap, which comprises an end cap body.The end cap body is equipped with a stepped hole for inserting a bearing.The stepped hole is equipped with a positioning structure for the axial positioning of the bearing.The positioning structure comprises steps arranged in the stepped hole, a groove radially arranged at the inner wall of the stepped hole and a axial back-up ring arranged in the groove.One sidewall of the outer ring of the bearing abuts against the end face of the steps and the sidewall of the axial back-up ring abuts against the other sidewall of the outer ring of the bearing.The utility model is simple in structure and easy in installation.According to the technical solution of the present utility model, the bearing assembled in the end cap is arranged at certain positions by the axial back-up ring and is prevented from axial float.The axial wearing between the bearing and the end cap is avoided and the service life thereof is prolonged, thereby improving the operational security.
Description
Technical field
The utility model relates to bearing (ball) cover, and 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.
The model utility content
Problem to be solved in the utility model just provides a kind of simple and reasonable bearing (ball) cover and improves structure, change the mounting point of bearing, make the axially locating of bearing more stable, weakened axial float, prolong the working life of bearing and end cap, improve Security.
In order to solve the problems of the technologies described above, the utility model 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 utlity model 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 utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a kind of embodiment's of the utility model a structural representation.
Embodiment
A kind of embodiment's of the utility model structural representation 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 utility model 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 utility model also has other mode of execution, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
Claims (3)
