Description
Technical field
It the utility model is related to field of bearings, more particularly to a kind of low friction rolling bearing of axial limiting.
Background technology
Bearing is a kind of important parts in contemporary plant equipment, and its major function is the mechanical rotary body of support, is dropped
Coefficient of friction in low mechanical rotary body motion process, and ensure its rotating accuracy.
By the difference of motor element frictional property, bearing can be divided into rolling bearing and the major class of sliding bearing two, wherein rolling
Bearing is normalized, seriation, but its radial dimension, vibration and noise are larger compared with sliding bearing, and price is also higher.
Rolling bearing is typically made up of outer ring, inner ring, rolling element and the part of retainer four, and rolling element is generally arranged at outer ring
Between inner ring, axial arrangement low intensity, abrasion when axial force is big is greatly, it is necessary to strengthen.
Utility model content
The purpose of this utility model is the low friction rolling bearing for providing a kind of axial limiting, and it is strong to lift axial arrangement
Degree, reduce abrasion.
To use following technical scheme up to this purpose, the utility model：
A kind of low friction rolling bearing of axial limiting, including：Bearing outer ring and bearing inner race, the bearing inner race are concentric
It is arranged among bearing outer ring, the back-up ring positioned at bearing inner race both sides, the back-up ring and bearing is provided with the bearing outer ring
A circle ball, the Spring Card being provided with the bearing outer ring on the outside of back-up ring, the bearing are respectively arranged between inner ring
The mounting groove corresponding with Spring Card is provided with the inwall of outer ring.
Wherein, the mesopore both ends of the bearing inner race are respectively arranged with the reinforcing ring to stretch out.
Wherein, annular groove corresponding with a circle ball is respectively arranged with the inside of the back-up ring.
Wherein, the bearing inner race both sides are respectively arranged with multiple arc grooves corresponding with single ball respectively.
Wherein, the bearing outer ring inwall evagination is provided with the first spacing ring corresponding with back-up ring, the back-up ring lateral surface
Edge is provided with a circle the second spacing ring corresponding with the first spacing ring.
Wherein, the bearing inner race both sides are respectively arranged with dust ring corresponding with back-up ring endoporus.
The beneficial effects of the utility model：A kind of low friction rolling bearing of axial limiting, bearing inner race is by axial work
When firmly, friction is reduced using the rolling of ball, reduction is worn, improving stability, and good dustproof effect is applied widely.

Groove 10, ball 3 is spacing by arc groove 10 one by one, is spaced apart, uniform force, and structure is more stable, avoids between ball 3
Friction.
In the present embodiment, the inwall evagination of bearing outer ring 1 is provided with first spacing ring 8 corresponding with back-up ring 6, the gear
Enclose 6 lateral surface edges and be provided with a circle and 8 corresponding second spacing ring 9 of the first spacing ring, the first spacing ring 8 and the second spacing ring
9 cooperation, improve the spacing of back-up ring 6, quick for installation, Stability Analysis of Structures.
In the present embodiment, the both sides of bearing inner race 2 are respectively arranged with dust ring 4 corresponding with the endoporus of back-up ring 6, gap
It is small, reduce influence of the dust to ball 3.
Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality
With new thought, there will be changes, this specification content should not be construed as in specific embodiments and applications
To limitation of the present utility model.
