Abstract

The utility model relates to a kind of self oiling bearing, described bearing includes inner ring (1) and outer ring (2) of coaxial setting, multiple rolling element (3) is evenly placed with between described inner ring (1) and outer ring (2), the surface of contact of described inner ring (1) and outer ring (2) and rolling element (3) is respectively arranged with caulking groove one (1.1) and caulking groove two (2.1), described caulking groove one (1.1) and caulking groove two (2.1) are all arranged to helical groove structure, have all been embedded to graphite block in described caulking groove one (1.1) and caulking groove two (2.1).A kind of self oiling bearing of the utility model, can lubricate Internal and external cycle and rolling element.

Description

A kind of self oiling bearing

Technical field

The utility model relates to a kind of bearing, especially relates to a kind of bearing with selflubricating effectiveness, belongs to technical field of bearings.

Background technique

At present, some key equipment of industrial and mining enterprise, due to the requirement of special producing technique, needs to run under very severe operating mode; As at comparatively high ambient temperature or in atmosphere containing the high corrosive environment of sour corrosion gas (CO, SO2 etc.); The lubricating system of conventional bearings adopts traditional oil, grease lubrication, and in fact aforesaid industrial and mineral condition beyond oil, grease lubrication scope, very easily there is biting or killing of bearing and other friction pairs, cause serious parts depreciation and damage, regularly cause equipment to be stopped transport; Therefore in order to produce continuous operation, except requiring that in original design installing multiple devices wheel repaiies, also a large amount of maintenance man must be dropped into; Seriously limit the raising of productivity, standby redundancy and energy consumption greatly, have become the significant obstacle of developping production;

For this reason, Corporation R & D is had to have the bearing of self-lubricating function, disclosed in Chinese patent ZL201410013187.9 " a kind of self oiling bearing ", its selflubricating mode makes equidistantly isolation mutually between rolling element for adopting retainer, and adopts dust cover form to seal, but it is basic to chase after it, it still adopts grease mode to lubricate, and after working long hours under high temperature height corrosive environment, grease easily dries up, thus make rotation dry and astringent, and then damage bearing; Need a kind of bearing truly with self-lubricating function badly for this reason.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of self oiling bearing that can lubricate Internal and external cycle and rolling element.

The purpose of this utility model is achieved in that

A kind of self oiling bearing, described bearing includes inner ring and the outer ring of coaxial setting, is evenly placed with multiple rolling element between described inner ring and outer ring,

The surface of contact of described inner ring and outer ring and rolling element is respectively arranged with caulking groove one and caulking groove two, described caulking groove one and caulking groove two are all arranged to helical groove structure, thus make when rolling, each face, each Structure deformation position all can obtain the lubrication of graphite, have all been embedded to graphite block in described caulking groove one and caulking groove two.

A kind of self oiling bearing of the utility model, the rolling surface of described rolling element is provided with multiple blind hole, and is all equipped with graphite block in blind hole.

Compared with prior art, the beneficial effects of the utility model are:

The utility model, in rotation process, is lubricated Internal and external cycle and rolling element by embedded graphite, thus the later stage is without the need to safeguarding; And be compared to grease mode, after adopting graphite, even if under high temperature height corrosive environment, graphite performance still remains unchanged, still along with rotation, powdered graphite can be spread upon on the surface of contact of Internal and external cycle and rolling element, thus provide lubrication to bearing; After adopting the utility model self oiling bearing, substantially increase the working life of bearing, decrease the use in later stage, maintenance cost; And the severe industrial and minerals such as high temperature height corrosion can be applied to, greatly improve the Applicable scope of bearing, add its market competitiveness.

Accompanying drawing explanation

Fig. 1 is the broken section effect schematic diagram of a kind of self oiling bearing of the utility model.

Wherein:

Inner ring 1, outer ring 2, rolling element 3;

Caulking groove 1, caulking groove 2 2.1, blind hole 3.1.

Embodiment

See Fig. 1, a kind of self oiling bearing that the utility model relates to, described bearing includes inner ring 1 and the outer ring 2 of coaxial setting, multiple rolling element 3 is evenly placed with between described inner ring 1 and outer ring 2, described inner ring 1 and the surface of contact of rolling element 3 are provided with caulking groove 1, and caulking groove 1 curl on inner ring 1 with the surface of contact of rolling element 3 is arranged (namely caulking groove 1 is set to helical groove structure), the advantage being arranged to this shape is, during rolling, rolling element 3 fully can contact with caulking groove 1, same outer ring 2 and the surface of contact of rolling element 3 are provided with caulking groove 2 2.1, and caulking groove 2 2.1 is arranged in the shape of a spiral (namely caulking groove 2 2.1 is set to helical groove structure) on outer ring 2 with the surface of contact of rolling element 3, graphite block has been embedded in described caulking groove 1 and caulking groove 2 2.1, simultaneously, the rolling surface of described rolling element 3 is provided with multiple blind hole 3.1, and be all equipped with graphite block in blind hole 3.1, thus make when rolling, graphite block can provide lubrication to bearing at any time,

In addition: it should be noted that above-mentioned embodiment is only an optimized project of this patent, any change that those skilled in the art does according to above-mentioned design or improvement, all within the protection domain of this patent.

Claims
