Abstract

The utility model provides a wear-resisting bearing. The wear-resisting bearing comprises a bearing inner ring, a bearing outer ring, a retainer arranged between the bearing inner ring and the bearing outer ring, and rolling bodies which are mounted in the retainer in an annular array. The wear-resisting bearing is characterized in that each rolling body is a rolling shaft or a rolling bead made of ceramic; an inner ring ceramic layer is arranged at the outer periphery of the bearing inner ring; an outer ring ceramic layer is arranged at the inner periphery of the bearing outer ring. According to the wear-resisting bearing provided by the utility model, each rolling body adopts a ceramic body; meanwhile, the layer of ceramic layer is arranged at each of the inner periphery of the bearing outer ring and the outer periphery of the bearing inner ring, which are contacted with the rolling bodies, so that the wear-resisting performance of the bearing is improved and the service life of the bearing is prolonged.

Description

A kind of anti-friction bearing

Technical field

The utility model relates to a kind of bearing, relates in particular to a kind of anti-friction bearing.

Background technique

Bearing is in mechanical transmission course, to work the parts of fixing and reducing load friction factor.Also can say, in the time that other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in power transmission process.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, the mechanical load friction factor in order to reduction equipment in transmission process.

General bearing all comprise bearing outer ring, bearing inner race and be located at bearing outer ring and bearing inner race between rotor.After the bearing of this structure has been grown service time, Metal Ball gets rusty easily and weares and teares, and shortens the working life of bearing.

Model utility content

The purpose of this utility model be to provide a kind of extend bearing use be a kind of anti-friction bearing in life-span.

To achieve these goals, a kind of anti-friction bearing that the utility model provides, comprise: bearing inner race, bearing outer ring, be located at the retainer between bearing inner race and bearing outer ring and be installed on the rolling element in retainer by annular row array, it is characterized in that, it is characterized in that, rolling element is roller bearing or the ball that pottery is made, and bearing inner race periphery is provided with inner ring ceramic layer, is provided with outer ring ceramic layer in bearing outer ring week.

In some embodiments, retainer is ceramic body.

In some embodiments, the inner ring ceramic layer of bearing inner race, the outer ring ceramic layer of bearing outer ring are equipped with ring raceway, and retainer and rolling element are located in raceway.

A kind of anti-friction bearing of the present utility model compared with prior art, has the following advantages:

1. anti-friction bearing of the present utility model, its rolling element adopts ceramic body, and in the bearing outer ring contacting with rolling element, week and bearing inner race periphery are equipped with one deck ceramic layer simultaneously, have improved the wear-resisting property of bearing, have extended the physical life of bearing.

Brief description of the drawings

Fig. 1 is the cross-sectional schematic of a kind of anti-friction bearing of a kind of mode of execution of the utility model.

Embodiment

Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail to explanation.

As depicted in figs. 1 and 2, a kind of bearing that simultaneously reduces friction that prevents from moving axially of the present utility model, comprising: bearing inner race 1, bearing outer ring 2, retainer 4 and rolling element 3.Rolling element 3 can be roller bearing or ball, in this mode of execution of the present utility model, and rolling element 3 roller bearings.

As shown in Figure 1, bearing inner race 1 is located in bearing outer ring 2, and bearing inner race 1 and bearing inner race 2 coaxially arrange.The interior Zhou Junshe ring raceway of bearing inner race 1 periphery and bearing outer ring 2.Roller bearing is installed in retainer 4 by annular row array, and the distance between each roller bearing equates.The retainer 4 that is embedded with roller bearing is located between bearing inner race 1 and bearing outer ring 2, and makes to roll in the raceway of roller bearing in bearing inner race 1 and bearing outer ring 2.

In this mode of execution of the present utility model, rolling element 3 and retainer 4 all adopt stupalith to make.The periphery side face of bearing inner race 1 is one deck ceramic layer 5, and the interior side face of bearing outer ring 2 is also one deck ceramic layer 6.

By said structure, adopt stupalith to make rolling element 3, retainer 4, make bearing inner race 1 periphery and the attached one deck ceramic layer of bearing outer ring 2 periphery simultaneously, improve the wear-resisting property of bearing, extend the physical life of bearing.

Claims
