Abstract

The utility model is related to Idler bearing technical fields, more particularly to a kind of anti-sticking Idler bearing, including bearing inner race and bearing outer ring, the both sides of groove on the bearing inner race are equipped with protrusion, the both sides of groove on the bearing outer ring open up groove, the protrusion and groove are oppositely arranged, it is equal at a distance from the inside of the bottom surface of the groove to distance and the bearing inner race outside to bearing outer ring of protrusion, longitudinal height of the protrusion is less than longitudinal depth of groove, is unlimited on the outside of the groove.The utility model has the beneficial effects that：The frequent generation that Idler bearing is stuck is prevented, the service life of Idler bearing is extended.

Description

A kind of anti-sticking Idler bearing

Technical field

The utility model is related to Idler bearing technical field, more particularly to a kind of anti-sticking Idler bearing.

Background technology

Many transporting equipments in progress of coal mining all use Idler bearing, but existing Idler bearing is due to working environment Compare badly, is susceptible to stuck phenomenon, reduces working efficiency, shorten the service life of Idler bearing.

Invention content

In order to solve problems in the prior art, the utility model provides a kind of anti-sticking support simple in structure, the long-life Roller bearing.

Technical solution described in the utility model is as follows：

A kind of anti-sticking Idler bearing, including bearing inner race and bearing outer ring, two of groove on the bearing inner race Side is equipped with protrusion, and the both sides of the groove on the bearing outer ring open up groove, and the protrusion and groove are oppositely arranged.

It is equal at a distance from the inside of the bottom surface of the groove to distance and the bearing inner race outside to bearing outer ring of protrusion.

Longitudinal height of the protrusion is less than longitudinal depth of groove.

It is unlimited on the outside of the groove.

The advantageous effect that technical solution provided by the utility model is brought is：

By the setting of protrusion and groove, dust is difficult to be directly entered bearing cage or groove, and dust is attached to carrying roller On bearing, just it is attached in groove before having not been entered into bearing cage or groove, during bearing outer ring rotates, Dust in groove can constantly fall off from outside, avoid enter into bearing cage or groove, prevent the frequency that Idler bearing is stuck Numerous generation extends the service life of Idler bearing.

Description of the drawings

It is required in being described below to embodiment 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.

Fig. 1 is the structural schematic diagram of the utility model section view.

Specific implementation mode

It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer Type embodiment is described in further detail.

As shown in Figure 1, a kind of anti-sticking Idler bearing, including bearing inner race 1 and bearing outer ring 2, the bearing inner race 1 On the both sides of groove be equipped with protrusion 3, the both sides of the groove on the bearing outer ring 2 open up groove 4,3 He of protrusion Groove 4 is oppositely arranged.

The distance of the bottom surface of the groove 4 to protrusion 3 arrives phase at a distance from 2 inside of bearing outer ring with 1 outside of bearing inner race Deng.

Longitudinal height of the protrusion 3 is less than longitudinal depth of groove 4.

The outside of the groove 4 is unlimited.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.

Claims
