Abstract
The utility model discloses a steering gear bearing. The steering gear bearing is characterized in that a steel ball (3) is mounted on a retainer (4) and is clamped between a channel of an inner ring (1) and a channel of an outer ring (2); an inner ring step (11) is formed on the inner ring (1); an outer ring step (21) is formed on the outer ring (2); a dustproof slot (211) is formed in the outer ring step (21); a dustproof cover (5) and a lip seal (6) are fixed; a hook-shaped clamping part (51) is formed on the left end of the dustproof cover (5) and is clamped in the dustproof slot (211); a lip (61) of the lip seal (6) props against a vertical plane (111) of the inner ring step (11). According to the steering gear bearing, the inside of the bearing is hermetically protected by the dustproof cover, the lip seal, the inner ring step and the outer ring step, so that the service life of the steering gear bearing is prolonged.
Description
Technical field:
The utility model relates to technical field of bearings, more specifically to a kind of automobile steering device bearing.
Background technique:
Automobile steering device is used frequent, so the bearing on automobile steering device also and then uses frequently, this just requires automobile steering device bearing to have better sealability, thereby guarantees that direction converter bearing has better working life.Existing automobile steering device bearing is generally continued to use Production of bearing technology during fabrication, the lip of lip envelope is pressed on the inwall of automobile steering device bearing inner race, and the inner ring of automobile steering device bearing was not done any processing, this just makes direction converter bearing can not have higher working life.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art; and provide a kind of direction converter bearing; it forms step on the inner ring of bearing and outer ring; allow lip resist on step surface; the inside of its bearing is subject to the multi-sealed protection of dust cover and lip envelope and inner ring step and outer ring step, thus the working life of having improved direction converter bearing.
Technology solution of the present utility model is as follows:
A direction converter bearing, comprises inner ring, outer ring, steel ball and retainer, and steel ball is arranged on retainer, steel ball is clamped between inner ring and outer ring raceway groove separately, on inner ring, moulding inner ring step forms outer ring step on outer ring, on the step of outer ring, forms dustproof groove;
Dust cover and lip envelope are fixed together, and the left end of dust cover forms hook-shaped fastening part, and hook-shaped fastening part is fastened in dustproof groove, and the lip of lip envelope resists on the vertical plane of inner ring step.
Described dust cover is stainless steel dust cover, and lip envelope is rubber lip envelope, and two parts up and down of retainer by closing-up together.
The beneficial effects of the utility model are:
It forms step on the inner ring of bearing and outer ring, allows lip resist on step surface, and the inside of its bearing is subject to the multi-sealed protection of dust cover and lip envelope and inner ring step and outer ring step, thus the working life of having improved direction converter bearing.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
In figure: 1, inner ring; 11, inner ring step; 111, vertical plane; 2, outer ring; 21, outer ring step; 211, dustproof groove; 3, steel ball; 4, retainer; 5, dust cover; 51, hook-shaped fastening part; 6, lip envelope; 61, lip; 7, rivet.
Embodiment:
Embodiment: as shown in Figure 1, a kind of direction converter bearing, comprise inner ring 1, outer ring 2, steel ball 3 and retainer 4, steel ball 3 is arranged on retainer 4, steel ball 3 is clamped between inner ring 1 and outer ring 3 raceway groove separately, on inner ring 1, moulding inner ring step 11 forms outer ring step 21 on outer ring 2, forms dustproof groove 211 on outer ring step 21;
Dust cover 5 is fixed together with lip envelope 6, and the left end of dust cover 5 forms hook-shaped fastening part 51, and hook-shaped fastening part 51 is fastened in dustproof groove 211, and the lip 61 of lip envelope 6 resists on the vertical plane 111 of inner ring step 11.
Described dust cover 5 is stainless steel dust cover, and lip envelope 6 is rubber lip envelope, and two parts up and down of retainer 4 rivet together by rivet 7.
