Description

A kind of reinforced conductive bearing

Technical field

The utility model is related to a kind of reinforced conductive bearing.

Background technology

Bearing is a kind of important spare part in contemporary plant equipment.Its major function is the mechanical rotary body of support, reduction Coefficient of friction in its motion process, and ensure its rotating accuracy.

The identical bearing of outward appearance under same condition of work, actual life differs widely.In addition with several different fixed The bearing " life-span " of justice, most important of which is so-called " working life ", and it represents that a certain bearing can reach before damage Actual life be by abrasion, damage generally not caused by fatigue, but caused by reasons such as abrasion, burn into bad seals. Therefore, bearing life is an important indicator of bearing parameter.

And bearing is under component environment, in use, electricity can be produced between the outer ring of bearing and inner ring in such as laser printer Potential difference, the Conducting forms of existing bearing are inner ring → conductive grease → rolling element → conductive grease → outer ring, and this Conducting forms are more Single, resistance is also larger, so that conductive effect is undesirable, causes the service life of bearing to be had a greatly reduced quality.

The content of the invention

In order to overcome the above-mentioned deficiency of existing bearing conductive capability, the utility model provides a kind of reinforced conductive bearing.

The technical scheme in the invention for solving the technical problem is：A kind of reinforced conductive bearing, including it is outer ring, interior Circle and the rolling element being arranged between outer ring and inner ring and the retainer for keeping rolling body position, described rolling element Note is provided with conductive grease between outer ring and inner ring, and conductive dust cap, the conduction are additionally provided between described outer ring and inner ring The outer end of dust cap contacts connection with described outer ring, and the inner of the conductive dust cap does not contact with described inner ring, described Inner ring be provided with note in dustproof groove, described dustproof groove and be provided with conductive grease, the inner of the conductive dust cap is stretched into described In conductive grease.

Further, described conductive dust cap is conductive dust cap or semiconductor dust cap.

Further, described rolling element is the steel ball that bearing steel is made.

Further, described conductive dust cap is brass dust cap.

The utility model is in use, it not only has the conductive shape of inner ring → conductive grease → rolling element → conductive grease → outer ring Formula, can also be by the Conducting forms of inner ring → conductive grease → conduction dust cap → outer ring, and pass through and change conductive dust cap Material, greatly improve the conductive capability of bearing, extend the service life of bearing.

The beneficial effects of the utility model are：Conductive path is added, and by the replacement of conductive dust-proof cover material, Conductive capability is greatly improved, so as to extend the service life of bearing.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of prior art.

Embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

1~Fig. 2 of reference picture, a kind of reinforced conductive bearing, including outer ring 1, inner ring 2 and it is arranged on outer ring 1 and inner ring Rolling element 3 between 2 and the retainer 4 for keeping the position of rolling element 3, between described rolling element 3 and outer ring 1 and inner ring 2 Note is provided with conductive grease 5, and conductive dust cap 6, the outer end of the conductive dust cap 6 are additionally provided between described outer ring 1 and inner ring 2 Connection is contacted with described outer ring 1, the inner of the conductive dust cap 6 does not contact with described inner ring 2, on described inner ring 2 Provided with dustproof groove 7, note is provided with conductive grease 5 in described dustproof groove 7, and described conduction is stretched into the inner of the conductive dust cap 6 In fat 5.In the present embodiment, described rolling element 3 is the steel ball that bearing steel is made.

In the present embodiment, described conductive dust cap 6 is conductive dust cap or semiconductor dust cap.It is preferred that, it is described Conductive dust cap is brass dust cap.Conventional dust cap 6 is mostly made of spcc or sus304, poorly conductive, Er Qieyi So that grease is spilt.And the brass that the present embodiment is used has good electric conductivity, and it is cheap, therefore be great sexual valence The conductive material of ratio.When being worked in many environments due to bearing, temperature is often raised, thus using semiconducting electrical conductivity with The characteristic temperature rise and improved, is made semiconductor dust cap 6, can also play preferable electric action.

The utility model is in use, it not only has 5 → outer ring of inner ring 2 → conductive grease, 5 → rolling element, 3 → conductive grease 1 Conducting forms, can also be by the Conducting forms of 2 → conductive grease of inner ring 5 → 6 → outer ring of conduction dust cap 1, and pass through and change The material of conductive dust cap 6, greatly improves the conductive capability of bearing, extends the service life of bearing.
