Description
[technical field]
This utility model relates to mechanical field, a kind of bearing reducing frictional force.
[background technology]
Bearing is a kind of important spare part in plant equipment in the present age.Its major function is to support machinery rotary body,
Reduce the coefficient of friction in its motor process, and ensure its rotating accuracy.By motor element frictional property not
With, bearing can be divided into rolling bearing and the big class of sliding bearing two.In current rolling bearing, although rolling element
Can roll, but retainer and rolling element sliding friction, bigger frictional force can be produced, cause rolling element
Rotary speed is limited, temperature is too high when rotating, and the life-span of bearing itself is affected by certain.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of axle reducing frictional force
Hold, it is possible to reduce the frictional force of rolling element further, improve bearing performance, extend the service life of bearing.
For achieving the above object, the utility model proposes a kind of bearing reducing frictional force, including outer ring,
Inner ring, rolling element, retainer and scroll wheel, be provided with inside described outer ring inner ring, described outer ring and inner ring it
Between be provided with some rolling elements, be provided with retainer between described rolling element, described retainer two ends are installed with 3
Individual scroll wheel, described scroll wheel and rolling element rolling friction.
As preferably, the outer surface of described inner surface and inner ring is equipped with groove, the width of groove and deep phase
Deng, and 1/3rd that depth of groove sum is rolling element diameter.
As preferably, described rolling element is cylindrical shape, the width phase of its length and outer ring and the groove of inner ring
With, and in the groove being placed on outer ring and inner ring that can be full of.
As preferably, described retainer is connected with rolling element by scroll wheel and can be distributed uniformly by rolling element
In groove, and retainer also can make self for equilibrium-like by its two ends scroll wheel with contacting of rolling element
State.
The beneficial effects of the utility model: this utility model passes through to fixedly mount scroll wheel at retainer two ends,
Make scroll wheel and rolling element rolling friction, reduce coefficient of friction, compared with prior art, it is possible to further
Reduce the frictional force of rolling element, improve bearing performance, extend the service life of bearing.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
[accompanying drawing explanation]
Fig. 1 is the structural representation of a kind of bearing reducing frictional force of this utility model.
In figure: 1-outer ring, 2-inner ring, 3-rolling element, 4-retainer, 5-scroll wheel.
[detailed description of the invention]
Refering to Fig. 1, a kind of bearing reducing frictional force of this utility model, including outer ring 1, inner ring 2, roll
Body 3, retainer 4 and scroll wheel 5, be provided with inner ring 2, described outer ring 1 and inner ring 2 inside described outer ring 1
Between be provided with some rolling elements 3, be provided with retainer 4 between described rolling element 3, described retainer 4 two ends are solid
Dingan County is equipped with 3 scroll wheels 5, described scroll wheel 5 and rolling element 3 rolling friction, described outer ring 1 inner surface
It is equipped with groove with the outer surface of inner ring 2, groove wide and the most equal, and depth of groove sum is rolling element 3
/ 3rd of diameter, described rolling element 3 in cylindrical shape, its length and outer ring 1 and the groove of inner ring 2
Width identical, and in the groove being placed on outer ring 1 and inner ring 2 that can be full of, described retainer 4 leads to
Cross scroll wheel 5 be connected with rolling element 3 and can be evenly distributed in groove by rolling element 5, and retainer 4
Also self can be made by its two ends scroll wheel 5 for poised state with contacting of rolling element 3.
Utility model works process:
This utility model is a kind of reduces the bearing of frictional force in the course of the work, by solid at retainer 4 two ends
Dingan County's dress scroll wheel 5, scroll wheel 5 contacts with rolling element 3, when bearing is in running order, scroll wheel
5 produce rolling friction with rolling element 3, reduce the coefficient of friction between scroll wheel 5 and rolling element 3, with existing
There is technology to compare, it is possible to reduce the frictional force of rolling element further, improve bearing performance, extend making of bearing
Use the life-span.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any to this
Scheme after utility model simple transformation belongs to protection domain of the present utility model.
