Description

The automobile bearing of built-in novel roller cage

Technical field

The utility model relates to automobile bearing fields, more particularly to the automobile shafts of roller cage novel built in one kind It holds.

Background technique

Bearing is a kind of important spare part in contemporary mechanical equipment, its major function is to support mechanical rotary body, is reduced Coefficient of friction in its motion process, and guarantee its rotating accuracy.Automobile bearing main function is load-bearing and the rotation for wheel hub Accurate guidance is provided, it had not only born axial load but also had born radial load, was a very important components, if automobile shafts The endurance held in radial load and axial load is not up to standard, will be excessive in the stress at bearing twocouese and cause to turn round Song, badly damaged bearing enable the roller of bearing to reduce and are rotated by bearing so needing to be designed bearing improvement And the radial load stress generated, this makes it possible to the service lifes for promoting bearing.

Utility model content

The utility model is mainly solving the technical problems that provide the automobile bearing of novel roller cage built in one kind, energy Motion state of enough control rollers for enabling bearing retainer more stable in Bearing inner.

In order to solve the above technical problems, the technical solution that the utility model uses is: providing novel rolling built in one kind The automobile bearing of sub- retainer, including bearing inner race, bearing outer ring, cylinder roller and retainer, the inner circumferential of the bearing outer ring Surface sets groove on the arc of circle recess, and the peripheral surface of the bearing inner race sets the arc lower groove of circle recess, described Bearing inner race is set to inside the centre bore of the bearing outer ring, and the retainer is located at the bearing inner race and the bearing outer ring Between, the retainer is the circular metal plate structure of head and the tail connection, and the upper and lower side of the retainer is not and in the bearing Circle and bearing outer ring contact, the inward at both ends portion of the retainer open up rectangular groove, and the inside grooves set institute Cylinder roller is stated, for the cylinder roller bosom through a piece shaft of connection, described shaft one end is connected to the groove Bottom surface sets the globoidal structure of indent on the two sidewalls of the groove.

In one preferred embodiment of the utility model, small size bearing built in the cylinder roller, the shaft with it is described Small size bearing connection.

In one preferred embodiment of the utility model, aperture mode of the groove in the retainer two sides is symmetrical Aperture or alternately aperture.

In one preferred embodiment of the utility model, the central diameter of the cylinder roller is greater than the diameter at both ends.

The beneficial effects of the utility model are: the major design point of the utility model with the roller that changes Bearing inner With the connection type of the structure of retainer, it may be said that be design in addition to a kind of novel retainer structure, retainer is in inside One metal plate-like object, both ends open up groove to which roller is connected to both ends, can be very good the stress of roller from both ends Uniformly, it is effectively reduced the radial force load of bearing.

Detailed description of the invention

It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Obtain other attached drawings, in which:

Fig. 1 is the structural schematic diagram of one preferred embodiment of automobile bearing of novel roller cage built in the utility model；

Fig. 2 is the structural schematic diagram of a preferred embodiment of shown retainer；

The components in the drawings are labeled as follows: 1, bearing inner race；2, bearing outer ring；3, cylinder roller；4, retainer；5, arc Groove in shape；6, arc lower groove；7, groove；8, shaft.

Specific embodiment

Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

Fig. 1 and Fig. 2 are please referred to, the utility model embodiment includes:

A kind of automobile bearing of built-in novel roller cage, including bearing inner race 1, bearing outer ring 2,3 and of cylinder roller Retainer 4, the inner peripheral surface of the bearing outer ring 2 set groove 5 on the arc of circle recess, the outer weekly form of the bearing inner race 1 Face sets the arc lower groove 6 of circle recess, and the bearing inner race 1 is set to inside the centre bore of the bearing outer ring 2, the holding For frame 4 between the bearing inner race 1 and the bearing outer ring 2, the retainer 4 is that the circular metal of head and the tail connection is hardened Structure, the upper and lower side of the retainer 4 are not contacted with the bearing inner race 1 and the bearing outer ring 2, the retainer 4 Inward at both ends portion opens up rectangular groove 7, and the cylinder roller 3,3 bosom of cylinder roller are set inside the groove 7 Through a piece shaft 8 of connection, described 8 one end of shaft is connected to the bottom surface of the groove 7, sets on the two sidewalls of the groove 7 interior Recessed globoidal structure.

In addition, small size bearing built in the cylinder roller 3, the shaft 8 is connect with the small size bearing.
