Description

A kind of anti skid bearing

[technical field]

The utility model relates to the technical field of machinery, particularly a kind of technical field of anti skid bearing.

[background technique]

Bearing is generally all made up of outer ring, inner ring, rolling element and retainer, and in most cases, the merging that matches of its inner ring and axle rotates together with the axis; Matching with bearing support in outer ring, plays a supportive role; Rolling element is evenly distributed between inner ring and outer ring by means of retainer, and retainer can make rolling element be uniformly distributed, and prevents rolling element from coming off, and guides rolling element to rotate lubricate.Bearing is generally all made up of outer ring, inner ring, rolling element and retainer.The periphery of existing bearing outer ring, the surface of matching with bearing support, all columniform, the endoporus of inner ring is cylindrical hole, and the bearing of this shape can not keep suitable matching relationship good between associated bearing support, axle for a long time, causes bearing support, axle and the wearing and tearing between it, produce gap, bearing skids and causes beating and deviating from of axle, and machinery can not normally be run, and causes the damage of other parts.

[model utility content]

The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of anti skid bearing, the structure between bearing and bearing support axle can be made more reasonable, effectively prevent the phenomenon that bearing wear is skidded, extend the physical life of bearing.

For achieving the above object, the utility model proposes a kind of anti skid bearing, comprise bearing outer ring, bearing inner race, rolling element and retainer, described rolling element shape is cylindrical, rolling element is between bearing outer ring and bearing inner race, rolling element is fixed by retainer, the internal surface of described bearing outer ring is provided with rolling element groove, the outer surface of bearing outer ring is provided with tread plate, the sidewall of described bearing inner race has a vertical breach, the outer surface of bearing inner race is provided with rolling element groove, and the outer surface of described bearing inner race is provided with annular slot.

As preferably, the quantity of described tread plate is some, and tread plate is vertically evenly distributed on the outer surface of bearing outer ring.

As preferably, the height of described bearing inner race is greater than the height of bearing outer ring, and described annular slot is arranged on the outer surface two ends of bearing inner race, and the quantity of annular slot is two, and each draw-in groove is all provided with fixing jump ring.

As preferably, the internal surface of described bearing inner race is roughened surface.

As preferably, the rolling element groove of described bearing inner race and bearing outer ring is left and right corresponding relation, and the gap between rolling element groove is a bit larger tham the diameter of rolling element.

The beneficial effects of the utility model: the utility model is by installing tread plate by bearing outer ring, bearing inner race is set to Anti-slip cover pattern, through optimum experimental, the structure between bearing and bearing support axle can be made more reasonable, effectively prevent the phenomenon that bearing wear is skidded, extend the working life of bearing.

Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.

[accompanying drawing explanation]

Fig. 1 is the plan view of a kind of anti skid bearing of the utility model;

Fig. 2 is the plan view of a kind of anti skid bearing of the utility model.

In figure: 1-bearing outer ring, 2-bearing inner race, 3-rolling element, 4-retainer, 5-rolling element groove, 6-tread plate, the vertical breach of 7-, 8-annular slot, 9-fix jump ring.

[embodiment]

Consult Fig. 1 and Fig. 2, a kind of anti skid bearing of the utility model, comprise bearing outer ring 1, bearing inner race 2, rolling element 3 and retainer 4, described rolling element 3 shape is cylindrical, rolling element 3 is between bearing outer ring 1 and bearing inner race 2, rolling element 3 is fixed by retainer 4, the internal surface of described bearing outer ring 1 is provided with rolling element groove 5, the outer surface of bearing outer ring 1 is provided with tread plate 6, the sidewall of described bearing inner race 2 has a vertical breach 7, the outer surface of bearing inner race 2 is provided with rolling element groove 5, the outer surface of described bearing inner race 2 is provided with annular slot 8, the quantity of described tread plate 6 is some, tread plate 6 is vertically evenly distributed on the outer surface of bearing outer ring 1, the height of described bearing inner race 2 is greater than the height of bearing outer ring 1, described annular slot 8 is arranged on the outer surface two ends of bearing inner race 2, the quantity of annular slot 8 is two, each annular slot 8 is all provided with fixing jump ring 9, the internal surface of described bearing inner race 2 is roughened surface, the rolling element groove 5 of described bearing inner race 2 and bearing outer ring 1 is in left and right corresponding relation, gap between rolling element groove 5 is a bit larger tham the diameter of rolling element 3.

Utility model works process:

A kind of anti skid bearing of the utility model in the course of the work, the fixing jump ring 9 of annular slot 8 is taken off, the bearing inner race 2 of vertical breach 7 is had easily to be enclosed within axle, load onto fixing jump ring 9, bearing inner race 2 is fixed on axle by elasticity extruding, bearing outer ring 1 is inserted in bearing support, tread plate 6 can strengthen the frictional force of bearing outer ring 1 and bearing support, prevent from skidding, the utility model is by installing tread plate 6 by bearing outer ring 1, bearing inner race 2 is set to Anti-slip cover pattern, through optimum experimental, the structure between bearing and bearing support axle can be made more reasonable, effectively prevent the phenomenon that bearing wear is skidded, extend the working life of bearing.

Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
