Abstract
The utility model specifically discloses a bearing retainer. The bearing retainer comprises a circular frame body, wherein a plurality of ball bags are uniformly distributed on the frame body, a dividing wall is formed between the ball bags, an oil storage hole is formed in the dividing wall, and the oil storage hole penetrates two adjacent ball bags. The bearing retainer is characterized in that a phosphating film layer is arranged on the surface of the frame body, the dividing wall is provided with a lug having two ends contacted with a rolling body along a direction axially vertical to steel ball. The phosphating film layer is arranged on the surface of the bearing retainer to provide protection for the bearing retainer, so that the surface of the bearing retainer is prevented from being corroded; since the dividing wall between the ball bags has the oil storage hole, the lubricating oil can be stored in the oil storage hole to lubricate the steel ball and the inner wall of the ball bag when the bearing is in working, the lubricating performance is improved, and the retainer is prevented from being damaged due to acute friction with the steel ball.
Description
Technical field
The utility model relates to a kind of Bearing fittings, relates to specifically a kind of retainer with less friction ractor.
Background technique
Existing bearing, its basic structure comprises inner ring, outer ring and be placed in, the steel ball as rolling element between outer ring, for steel ball is separated uniformly, and guide steel ball to remain on raceway to move, steel ball need be connected on a retainer, conventionally retainer is a cyclic structure, on its support body, be uniformly distributed and be provided with ball pocket, the shape of ball pocket and size need match with steel ball, be exactly while assembling specifically, after steel ball is embedded in ball pocket, steel ball can rotate freely in ball pocket, simultaneously, steel ball can not be deviate from again in ball pocket, for the flexibility that guarantees that steel ball rotates in ball pocket, conventionally after completing, bearing assemble also need between Internal and external cycle, seal up sealing gasket, retainer and steel ball are enclosed in the space of a sealing, and inject lubricant oil in this space, internally, outer ring is lubricated with the relative rolling between steel ball.But the retainer of existing ball bearing, because the gap between steel ball and ball pocket is less, lubricant oil cannot fully be lubricated with the relative rolling between ball pocket steel ball, causes because the friction between steel ball and ball pocket is compared with damaging retainer greatly, and then has affected the working life of bearing.
Model utility content
For overcoming above-mentioned defect, the utility model aims to provide a kind of retainer can be fully steel ball being lubricated with relative rolling between ball pocket.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of retainer, the support body that comprises a round, on described support body, be evenly distributed with several ball pockets, between described ball pocket, it is partitioning wall, on described partitioning wall, there is store oil hole, described store oil hole connects adjacent two ball pockets, on the surface of described support body, is provided with phosphorization membrane, and described partitioning wall is along being provided with the axial vertical direction of steel ball the projection that two ends contact with rolling element.
Position in the inside and outside cambered surface correspondence of described support body between every two ball pockets is equipped with groove.In each groove, all corresponding card is placed with the supporting element that outer surface is given prominence to the corresponding cambered surface of retainer body; Described retainer can significantly reduce the area of contact between the inside and outside cambered surface of retainer and the corresponding inside and outside circle of bearing, thereby effectively reduces the frictional force of bearing in operation process, corresponding working life of improving bearing.
The beneficial effects of the utility model are:
Retainer surface in the utility model is provided with phosphorization membrane; this phosphorization membrane can provide protection for retainer; the surface that prevents retainer is corroded; owing to being provided with store oil hole on the partitioning wall between ball pocket; when bearing working; lubricant oil can be stored in store oil hole steel ball and ball pocket inwall are lubricated, and has improved its greasy property, has avoided retainer because damaging with the violent friction of steel ball.
Accompanying drawing explanation
The structural drawing of the projection part on Fig. 1 partitioning wall;
Fig. 2 overall structure figure of the present utility model.
In figure: 1 oil storage hole, 2 partitioning walls, 3 steel balls, 4 projections, 5 ball pockets, 6 support bodys.
Embodiment
As shown in Fig. 1 and Fig. 2, the utility model discloses a kind of retainer, the support body 6 that comprises a round, on described support body 6, be evenly distributed with several ball pockets 5, between described ball pocket 5, be partitioning wall 2, during assembling, the steel ball 3 as rolling element embedded in ball pocket 5, on described partitioning wall 2, have store oil hole 1, described store oil hole 1 connects adjacent two ball pockets 5.Conventionally the axis in store oil hole 1 and the inwall of ball pocket 5 keep substantially vertical, and when bearing working, the lubricant oil being stored in store oil hole 1 can be lubricated steel ball and ball pocket 5 inwalls.On the surface of support body 6, be provided with phosphorization membrane; this phosphorization membrane can provide protection for retainer; the surface that prevents retainer is corroded, and described partitioning wall 2 is along being provided with the axial vertical direction of steel ball 3 projection 4 that two ends contact with rolling element.On the face contacting with steel ball, be provided with oil storage grooves on described support body.
Position in the inside and outside cambered surface correspondence of described support body 6 between every two ball pockets 5 is equipped with groove.In each groove, all corresponding card is placed with the supporting element that outer surface is given prominence to the corresponding cambered surface of retainer body; Described retainer can significantly reduce the area of contact between the inside and outside cambered surface of retainer and the corresponding inside and outside circle of bearing, thereby effectively reduces the frictional force of bearing in operation process, corresponding working life of improving bearing.
Claims (2)
1. a retainer, the support body that comprises a round, on described support body, be evenly distributed with several ball pockets, between described ball pocket, it is partitioning wall, on described partitioning wall, there is store oil hole, described store oil hole connects adjacent two ball pockets, it is characterized in that: on the surface of described support body, be provided with phosphorization membrane, described partitioning wall is along being provided with the axial vertical direction of steel ball the projection that two ends contact with rolling element.
2. retainer as claimed in claim 1, it is characterized in that: the position in the inside and outside cambered surface correspondence of described support body between every two ball pockets is equipped with groove, in each groove, all corresponding card is placed with the supporting element that outer surface is given prominence to the corresponding cambered surface of retainer body.
