Abstract

The utility model relates to a maintainer for a roller bearing, relating to the field of bearings. The maintainer for the roller bearing comprises a maintainer body. At least one groove is arranged on each contact face of the maintainer body; and the openings at both ends of the groove are respectively arranged on the end faces at the left and the right ends of the contact face of the corresponding maintainer body. With the adoption of the maintainer, the surface of a roller in contact with the contact faces of the maintainer is effectively lubricated when the bearing works thereby avoiding, the phenomenon that the running life of the bearing is shortened caused by dry rotation of the roller.

Description

A kind of roller bearing retainer

[technical field]

The utility model relates to field of bearings, especially relates to a kind of roller bearing retainer that is used for roller bearing.

[background technique]

Known, bearing cage is an important component part of bearing, and it mainly acts on is that a plurality of rolling elements with in the bearing are equally spaced, runs foul of each other and rubs to prevent that a plurality of rolling elements from producing when the bearing working; Bearing is under normal operative condition, installed and the influence of working strength, retainer in the bearing can be subjected to bigger impact force, if run into the inadequate situation of rolling element surface lubrication again, the damage phenomenon very easily takes place in retainer because of frictional force is excessive, thereby causes the drought rolling of crossing because of rolling element that bearing is scrapped; At present, general bearing is divided into ball bearing and roller bearing by its inner rolling element pattern, with regard to roller bearing, it generally is the surface that the grease that will be used to lubricate earlier is coated on a plurality of rollers respectively uniformly, a plurality of rollers are assembled to respectively between corresponding two retainers again, and finally are assembled into bearing; Because the surface of contact that existing retainer contacts with roller is even surface, with reference to Fig. 1, therefore, stripping is scraped at the surface of contact edge that such coating method very easily causes the grease of roller surface to be held device in bearing working, and can't carry out effective lubricating to the roller surface that contacts with the retainer surface of contact, thereby very easily make roller produce rigid friction, not only influenced the running life of bearing, but also very easily caused bearing to scrap at the long-time surface of contact that rolls back and retainer.

[summary of the invention]

In order to overcome the deficiency in the background technique, the utility model discloses a kind of roller bearing retainer, described retainer can make the roller surface that contacts with the retainer surface of contact obtain effective lubricating in bearing working, thereby has avoided bearing to cross the phenomenon generation that the drought rolling influences the reduction of bearing operation life-span because of roller.

To achieve these goals, the utility model adopts following technological scheme:

A kind of roller bearing retainer, described retainer comprises the retainer body; All be provided with a groove on each surface of contact of described retainer body at least, and the both ends open of groove lays respectively at the end face at corresponding two ends, this contact level of retainer left and right sides.

Described roller bearing retainer, the groove on each surface of contact of described retainer body all is provided with two at least, and the middle part of the groove on same surface of contact is provided with connectivity slot.

Owing to adopt aforesaid technological scheme, the utlity model has following beneficial effect:

Described roller bearing retainer, by when the groove of the surface of contact setting of retainer body has effectively been avoided roller at high speed scroll, this contact level of retainer edge is to the stripping of scraping of roller surface lubricant grease, thereby makes the roller in the roller bearing have preferable lubricating condition; When roller bearing runs up, described groove not only can make the lubricant grease of roller surface along in the opening inflow groove of groove, the roller surface that contacts with this contact level of retainer is carried out fully lubricated, but also can play the effect of effective storage lubricant grease; In addition, described groove has also reduced the area of contact between roller and this contact level of retainer, has effectively reduced frictional force, makes the on-stream vibrating noise that reduced of roller bearing after the assembling, improve the stationarity of running, thereby prolonged the running life of roller bearing.

Fig. 1 is existing retainer schematic representation;

Fig. 2 is a schematic representation of the present utility model;

Fig. 3 is an another kind of structural representation of the present utility model.

Among the figure: 1, retainer body; 2, surface of contact; 3, groove; 4, connectivity slot.

[embodiment]

Can explain the utility model in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope, and the utility model is not limited to the following examples;

1 described roller bearing retainer in conjunction with the accompanying drawings, described retainer comprises retainer body 1; All be provided with a groove 3 at least on each surface of contact 2 of described retainer body 1, and the both ends open of groove 3 lays respectively at the end face at corresponding two ends, retainer body 1 surface of contact, 2 left and right sides, be that roller is when high speed scroll, the lubricant grease of roller surface can flow into groove 3 inside by each bar groove 3 openings at two ends, thereby the roller surface that contacts with retainer body 1 surface of contact 2 is carried out lubricated fully; In addition, the groove 3 on each surface of contact of described retainer body all is provided with two at least, and is provided with connectivity slot 4 at the middle part that is positioned at the groove 3 on the same surface of contact, with the lubricated face of effective increase roller surface, thereby further strengthens lubrication effect.

When implementing roller bearing retainer described in the utility model, only need described retainer is assembled in the corresponding roller bearing, promptly can be when this roller bearing runs up, undertaken lubricated fully by the lubricant grease pair roller surface that contacts with retainer body 1 surface of contact 2 of inserting in advance or flowing in the described groove 3, described groove 3 has also reduced the area of contact between roller and retainer body 1 surface of contact 2 simultaneously, effectively reduced retainer suffered frictional force in bearing runs up, thus corresponding running life that prolongs roller bearing.

Carefully not stating in the above content is prior art partly, does not state so run business into particular one.

Claims
