Abstract

The utility model discloses a kind of hub bearing assembly of the back-to-back installation of retainer, including outer ring, inner ring, seal assembly, retainer, steel ball, the retainer end face is zigzag, and two retainer back-to-back installations during installation, i.e., the sawtooth of two retainer end faces is mutually matched occlusion.The utility model carries out mill processing simultaneously to inner ring and mandrel, effectively solves the problems, such as problem on deformation, two row raceway groove parallel errors and two row raceway grooves after existing inner ring and mandrel interference fit not concentricity problem, reduce product to do over again, improve production efficiency, at the same improve the life-span of product and on automobile after ride comfort.

Description

A kind of hub bearing assembly of the back-to-back installation of retainer
Technical field
It the utility model is related to a kind of hub bearing assembly, and in particular to a kind of hub bearing of the back-to-back installation of retainer Assembly.
Background technology
In recent years, China's automobile industry was in the high-speed developing period, and volume of production and marketing improves constantly, and considers from long term growth, respectively Individual manufacturer and user propose higher requirement to complete vehicle quality.The main function of automobile hub bearing is load-bearing and is wheel hub Rotation accurate guiding is provided, it had not only born axial load but also had born radial load, was a very important parts.Automobile The structure of hub bearing retainer is improved and development all possesses following feature:
1)On the basis of proof strength, bearing roller can be made to be increased in quantity or physical dimension, to carry The bearing capacity and service life of high bearing.
2)Possess the ability for the self-lubricating for being improved bearing, while noise can be reduced.Meet that bearing improves rotating speed and subtracted The requirement of few noise.
3)Possessing has the influence for saving material and reducing to surrounding enviroment.Improving stock utilization and saving material is The limited resources growing tension of trend of the times, especially copper product, all the structure of retainer is improved for copper for copper, to mould with steel Facilitation is served with replacement.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of hub bearing assembly of the back-to-back installation of retainer, Retainer end face " sawtooth " back-to-back installation, in limited bearing interior space, it is uniform to improve steel ball size and steel ball Quantity, greatly improves the bearing capacity of product, and alleviates the overall quality of product.
Technical scheme is used by the utility model solves technical problem:A kind of hub spindle of the back-to-back installation of retainer Hold assembly, including outer ring, inner ring, seal assembly, retainer, steel ball, the retainer end face is zigzag, two guarantors during installation The back-to-back installation of frame is held, i.e., the sawtooth of two retainer end faces is mutually matched occlusion.
As a preferred embodiment, retainer (4) material is the glass fibre of nylon66 fiber+25%.
It is on the basis of proof strength that the utility model, which mainly improves, steel ball can be made to be increased in quantity, bearing External dimensions is reduced, and is played and is saved the effect such as material, space.Using the glass fibre of nylon66 fiber+25%, retainer material warp Thermostabilization, there is good intensity and elasticity.Because it shows there is good slipping property after lubrication in steel, retainer production Raw friction is greatly reduced, therefore the heating and friction of bearing can reach low degree.It can keep good in the case of temporary transient oil starvation Good runnability, operating temperature are less than 120 DEG C, can meet that domestic and most countries automobile hub bearing makes more than -40 DEG C With requiring.
The beneficial effects of the utility model are:By retainer end face " sawtooth " back-to-back installation, in limited bearing In portion space, steel ball size and the uniform quantity of steel ball are improved, greatly improves the bearing capacity of product, and alleviate production The overall quality of product.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of the utility model embodiment retainer.
The utility model is described further below in conjunction with the accompanying drawings.
Embodiment
As shown in accompanying drawing 1, Fig. 2, a kind of hub bearing assembly of the back-to-back installation of retainer, including it is outer ring 1, inner ring 2, close Sealing assembly 3, retainer 4, steel ball 5, the end face of retainer 4 are zigzag, two 4 back-to-back installations of retainer during installation, i.e., The sawtooth of two end faces of retainer 4 is mutually matched occlusion.The material of retainer 4 is the glass fibre of nylon66 fiber+25%.Sealing group Part 3 makes whole working position form a sealing system, not affected with dust, prevents grease from outflowing.
During assembling, 13 a diameter of S φ 13.4938 steel ball 5 is put into the pocket hole of retainer 4, is respectively put into outer Enclose in 1 two raceway grooves, appropriate grease is injected at two row steel balls with grease filling machine, then two inner rings 2 are knocked in into outer ring respectively, be allowed to It is integrally formed, is finally divided with hydraulic press pressure in the other indentation sealing component 3 in outer ring both sides, assembling terminates.

Claims (2)
