Abstract
The utility model discloses a kind of retainer, including support body, the pocket hole for placing steel ball is provided with described support body, described pocket hole is set in half elliptic, cavity is provided between pocket bottom hole portion and steel ball, wear-resistant block is provided with described cavity, the both ends of the wear-resistant block are fixed on pocket hole, arched to steel ball direction at the middle part of wear-resistant block, and it is in contact with steel ball, the spring for promoting the middle part of wear-resistant block to be contacted with steel ball holding is additionally provided between the wear-resistant block and pocket bottom hole portion, multiple exhaust through holes are additionally provided with described wear-resistant block.By using said structure, the utility model provides a kind of retainer for effectively improving Bearing inner heat dispersion.
Description
Technical field
It the utility model is related to technical field of bearings, and in particular to a kind of retainer.
Background technology
At present, the pocket hole on retainer is generally spherical or cylindrical, and it is wrapped in outside steel ball, is typically with steel ball
It is in close contact, and during bearing working, steel ball is to be constantly in rotate at a high speed, therefore the temperature of Bearing inner is generally higher, and is dissipated
Hot property is poor.
The content of the invention
In view of the shortcomings of the prior art, the utility model provides a kind of axle for effectively improving Bearing inner heat dispersion
Hold retainer.
To achieve the above object, the utility model provides a kind of retainer, including support body, is set on described support body
The pocket hole for placing steel ball is equipped with, described pocket hole is set in half elliptic, and cavity is provided between pocket bottom hole portion and steel ball,
Wear-resistant block is provided with described cavity, the both ends of the wear-resistant block are fixed on pocket hole, and the middle part of wear-resistant block is to steel ball direction
Arch, and be in contact with steel ball, the middle part for promoting wear-resistant block is additionally provided between wear-resistant block and pocket the bottom hole portion and steel ball is protected
The spring of contact is held, multiple exhaust through holes are additionally provided with described wear-resistant block.
The beneficial effects of the utility model are：Using said structure, bearing working, steel ball rotation, so as to wear-resistant block shape
Into pressing, wear-resistant block is replied under the action of the spring after being pressed, and the exhaust through hole on wear-resistant block can give off in the process
Gas, and steel ball is blowed to, so as to play certain thermolysis to steel ball, and drive the air circulation of Bearing inner, Jin Eryou
The heat dispersion of effect lifting Bearing inner.
The both ends end that the utility model can be further arranged to the wear-resistant block is set in dovetail shaped, on described pocket hole
It is correspondingly provided with and forms the dovetail shaped neck connected and fixed with wear-resistant block dovetail shaped end.In this way, simple in construction, assembling side
Just, and assemble after firm and reliable connection.
The projection that stationary positioned spring is additionally provided with for the pocket bottom hole portion may further be provided in the utility model.So
Set, effective positioning can be formed to spring, prevents its movement.
The utility model may further be provided is symmetrically positioned in spring both sides for the exhaust through hole.In this way, structure
More rationally, radiating effect is preferable.
Brief description of the drawings
Fig. 1 is cross-sectional view of the present utility model；
Fig. 2 is Fig. 1 A portions enlarged drawing.
Embodiment
A kind of retainer, including support body 1 are given as shown in Figure 1, 2, are provided with described support body 1 for placing
The pocket hole 11 of steel ball 2, described pocket hole 11 are set in half elliptic, and cavity 12, institute are provided between the bottom of pocket hole 11 and steel ball 2
Wear-resistant block 3 is provided with the cavity 12 stated, the both ends end 31 of the wear-resistant block 3 is set in dovetail shaped, on described pocket hole 11
It is correspondingly provided with and forms the dovetail shaped neck 13 connected and fixed with wear-resistant block dovetail shaped end 31.The middle part of wear-resistant block 3 is to the side of steel ball 2
To arching, and be in contact with steel ball 2, be additionally provided between the wear-resistant block 3 and the bottom of pocket hole 11 promote the middle part of wear-resistant block 3 with
Steel ball 2 keeps the spring 4 of contact, and the bottom of pocket hole 11 is additionally provided with the projection 14 of stationary positioned spring 4.Described wear-resistant block
Multiple exhaust through holes 32 are additionally provided with 3, the exhaust through hole 32 is symmetrically positioned in the both sides of spring 4.
Using said structure, bearing working, steel ball 2 rotates, and is pressed so as to be formed to wear-resistant block 3, after wear-resistant block 3 is pressed
Replied in the presence of spring 4, the exhaust through hole 32 on wear-resistant block 3 can give off gas in the process, and blow to steel ball 2,
So as to play certain thermolysis to steel ball 2, and the air circulation of Bearing inner is driven, and then effectively lift Bearing inner
Heat dispersion.
