Description
Technical field
A kind of Neto formula retainer for new-energy automobile is the utility model is related to, belongs to retainer technical field.
Background technology
For bearing as part essential in plant equipment, highly important work is played in the normal operation to plant equipment
With especially in some sensitive instrument and equipments, the service behaviour of bearing has very big to the using effect of whole instrument and equipment
Influence.High-speed precision bearing has stability of rotation, and bearing capacity is strong, and noise is low, the advantages that good heat dissipation, wherein retainer
As the important component of high-precision bearing, the optimization design of its structure is very necessary, and retainer is mainly used in
Even separation roller, guiding rolling element rotate and keep rolling element to be maintained in bearing.Existing retainer is straight by steel ball hole
Connecing and steel ball is isolated, contacted between steel ball and steel ball hole inwall for point, this and will greatly reduce the lifting surface area of steel ball,
Easily cause steel ball to be worn, and then influence machine operation.
The content of the invention
The purpose of this utility model is to provide a kind of Neto formula retainer for new-energy automobile, existing so as to solve
Fixation of the retainer to steel ball there is a situation where unstable, while reduce the friction between retainer and steel ball, it is ensured that retainer
Performance.
A kind of Neto formula retainer for new-energy automobile, including retainer, steel ball hole, wherein steel ball hole are uniformly distributed
In the periphery of retainer, it is characterised in that：Retainer is installed in the steel ball hole, and two are installed with each steel ball hole
Individual relative retainer；The retainer includes supporting plate and fixing axle, and supporting plate is fixedly installed in the middle part of fixing axle；The supporting plate is set
There is an intrados, the intrados of two supporting plates in same steel ball hole is oppositely arranged；Endoporus is provided with the middle part of the fixing axle, inside
Spring is provided with the middle part of hole, and respectively has a telescopic shaft to be inserted at endoporus both ends, under the action of the spring, two telescopic shafts can
To be retracted in endoporus, and endoporus can be stretched out；Axis hole is set in the side wall in the steel ball hole, and axis hole and retainer axle center are same
To the telescopic shaft is arranged in axis hole.
By adding interior bracket in steel ball hole steel ball can be avoided directly to contact the edge in steel ball hole, and then avoid steel ball
The edge in hole is to abrasion uneven caused by steel ball.Two supporting plates on interior bracket can hold two sections of steel ball, and this is not only
Fixed steel ball can be played a part of, moreover it is possible to increase the contact area of steel ball and supporting plate, be advantageous to the smearing of lubricating fluid, can be obvious
Fixed performance of the retainer to steel ball is improved, extends the service life of retainer and steel ball so that equipment operation is more stable.
Further, the radius of curvature of the intrados set on the supporting plate is equal to the radius of steel ball.When the curvature of intrados
When radius is equal to the radius of curvature of steel ball, the intrados on two supporting plates can fully contact with steel ball, increase contact area,
This can be avoided the abrasion that contact is brought to steel ball, while lubricant uniform the can be applied on steel ball by intrados, be entered
One is improved steel ball lubricity and improves machine operation surely.
Further, the intrados edge sets rounding.Because intrados directly contacts with steel ball, the rounding of intrados
Corner edge will not cause to wear to steel ball, while is also avoided that and blows the lubricating fluid on steel ball off, increase between supporting plate and steel ball
Greasy property.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is the disassembled form structural representation of interior bracket of the present utility model.
It is retainer 1, steel ball hole 2, interior bracket 3, steel ball 4, axis hole 5, supporting plate 31, intrados 32, fixing axle 33, interior in figure
Hole 34, telescopic shaft 35, spring 36.
Embodiment
It is better embodiment of the present utility model below, but does not therefore limit the scope of protection of the utility model.
As illustrated, a kind of Neto formula retainer for new-energy automobile, including retainer 1, wherein steel ball hole 2, steel
The hole of bead 2 is evenly distributed on the periphery of retainer 2, it is characterised in that：Retainer 3 is installed in the steel ball hole 2, and each
Two relative retainers 3 are installed in steel ball hole 2；The retainer 3 includes supporting plate 31 and fixing axle 33, and supporting plate 31 is fixed and set
Put at the middle part of fixing axle 33；The supporting plate 31 is provided with intrados 32, the intrados 32 of two supporting plates 31 in same steel ball hole 2
It is oppositely arranged；The middle part of fixing axle 33 is provided with endoporus 34, is provided with spring 36 at the middle part of endoporus 34, and respectively have at the both ends of endoporus 34
One telescopic shaft 35 is inserted, and in the presence of spring 36, two telescopic shafts 35 can be retracted in endoporus 34, and can be stretched
Go out endoporus 34；Axis hole 5 is set in the side wall in the steel ball hole 2, and axis hole 5 and the axle center of retainer 1 are in the same direction, and the telescopic shaft 35 is installed
In axis hole 5.
Further, the radius of curvature of the intrados 32 set on the supporting plate 31 is equal to the radius of steel ball 4.When intrados 32
Radius of curvature when being equal to the radius of curvature of steel ball 4, the intrados 32 on two supporting plates 31 can fully contact with steel ball, increase
Contact area, this can be avoided the abrasion that a contact is brought to steel ball 4, while intrados 32 can apply lubricant uniform the
It is put on steel ball 4, enters one and improve the lubricity of steel ball 4 raising machine operation surely.
Further, the edge of intrados 32 sets rounding.Because intrados 32 directly contacts with steel ball 4, intrados
32 rounding corner edge will not cause to wear to steel ball, while is also avoided that and blows the lubricating fluid on steel ball 4 off, increase supporting plate 31
With the greasy property between steel ball 4.
The utility model devises the Neto formula retainer for new-energy automobile, by adding interior bracket in steel ball hole
Steel ball can be avoided directly to contact the edge in steel ball hole, and then avoid the edge in steel ball hole to mill uneven caused by steel ball
Damage.Two supporting plates on interior bracket can hold the both ends of steel ball, and this can not only play a part of fixed steel ball, moreover it is possible to increase steel
Pearl and the contact area of supporting plate, be advantageous to the smearing of lubricating fluid, fixed performance of the retainer to steel ball can be significantly improved, extend
The service life of retainer and steel ball so that equipment operation is more stable.
