Abstract

The utility model relates to a bearing with a self-locking retainer ring. The bearing with the self-locking retainer ring comprises inner rings, an outer ring and a rolling body, wherein the rolling body is embedded in a rolling passage formed between the inner rings and the outer ring. The bearing with the self-locking retainer ring is characterized in that the retainer ring for limiting the rolling body is installed on the end surfaces of one sides of the inner rings, the retainer ring is clamped on the end surfaces of the inner rings through an inclined stopping opening structure, and is in clearance fit with the inner rings. The bearing with the self-locking retainer ring has the advantages that because the retainer ring is matched with the end surfaces of the inner rings through inclined stopping openings, a locking piece is formed on the connection positions of two inner rings and the retainer due to the adoption of a high point of an inclined plane and a lower point of the inclined point, and the retainer ring is fixed. However, because the retainer ring is in clearance fit with the inner rings, the retainer ring can rotate on the inner rings to a certain degree, and ball-assembling notches can be conveniently adjusted.

Description

A kind of bearing with the self-locking back-up ring

Technical field

The utility model relates to a kind of bearing, particularly a kind of bearing with the self-locking back-up ring.

Background technique

Bearing is a kind of very important component in contemporary machinery.Its major function is the supported mechanical solid of rotation, the mechanical load friction factor in order to reduction equipment in transmission process.Press the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two classes.In rolling bearing, back-up ring just is equivalent to the rib of an activity, being used for keeping off roller uses, traditional mounting type of pressing adopts flat fixing structure, it adopts the mode of interference fit to be locked on the end face of bearing inner race, its processed complex, and cost is high, and easily cause the endoporus deformation of inner ring, affect product quality.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of processing, the easy for installation and on-deformable bearing with the self-locking back-up ring of inner ring.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of bearing with the self-locking back-up ring, comprise inner ring, outer ring, rolling element, the raceway that forms between inner ring and outer ring is embedded with rolling element, its innovative point is: a side end face of described inner ring is equipped with the back-up ring spacing to rolling element, described back-up ring is fastened on the end face of inner ring by oblique fixing structure, and back-up ring coordinates with the inner ring gap.

Further, the oblique fixing structure of described back-up ring and inner ring joint is: described inner ring end face is processed into the inverted cone-shaped boss, and back-up ring is for being fastened on the structure on the inverted cone-shaped boss.

The utility model has the advantage of: the end face of back-up ring and inner ring utilizes the height on inclined-plane in two inner rings and back-up ring joint formation hold depth by oblique fixing structure Spielpassung, realizes the fixing of back-up ring; And back-up ring coordinates with the inner ring gap, and certain rotation can occur on inner ring back-up ring, adjusts filling slot convenient.

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

As shown in Figure 1, comprise inner ring 1, outer ring 3, rolling element 2 and back-up ring 4.

Be provided with the groove that arranges along circumferentially on the internal surface of the outer surface of inner ring 1 and outer ring 3, behind the outer suit of inner ring 1 outer ring 3, the groove looping raceway of inner ring 1 and outer ring 3, this raceway is embedded with rolling element 2, and this rolling element 2 can be cylindrical roller or spin.

One side end face of inner ring 1 is equipped with the back-up ring 4 spacing to rolling element 2, back-up ring 4 fastens by oblique fixing structure and is arranged on the end face of inner ring 1, this back-up ring 4 with the oblique fixing structure of inner ring 1 joint is: inner ring 1 end face is processed into the inverted cone-shaped boss, back-up ring 4 is for being fastened on the structure on the inverted cone-shaped boss, and back-up ring 4 coordinates with inner ring 1 gap, makes back-up ring 4 to rotate on the inverted cone-shaped boss of inner ring 1.

Claims

1. bearing with the self-locking back-up ring, comprise inner ring, outer ring, rolling element, the raceway that forms between inner ring and outer ring is embedded with rolling element, it is characterized in that: a side end face of described inner ring is equipped with the back-up ring spacing to rolling element, described back-up ring is fastened on the end face of inner ring by oblique fixing structure, and back-up ring coordinates with the inner ring gap.

2. a kind of bearing with the self-locking back-up ring according to claim 1 is characterized in that: the oblique fixing structure of described back-up ring and inner ring joint is: described inner ring end face is processed into the inverted cone-shaped boss, and back-up ring is for being fastened on the structure on the inverted cone-shaped boss.
