Abstract
The utility model relates to a bearing assembly for an automobile steering device, which comprises a bearing bushing and an elastic rubber bearing in the bearing bushing, wherein the bearing bushing comprises an outer ring and an inner ring which are bonded with each other through rubber; a flange is arranged at one end of the inner ring; the other end is subject to riveting, locking and point-sealing, so as to be in the inner ring after the elastic rubber bearing is installed in the inner ring; annular grooves are arranged at opposite positions inside the outer ring and outside the inner ring respectively; the rubber is embedded in the annular grooves after being vulcanized; the elastic rubber bearing comprises a rubber jacket which is internally provided with a retainer; a roller pin is installed on the retainer; an elastic outer ring is arranged between the retainer and the rubber jacket; and a framework is arranged on the rubber jacket. Through the adoption of the structure, the bearing assembly solves the problems that the inner ring and the outer ring fall off for the vulcanization bonding is not firm, and the elastic rubber bearing falls off the bearing bushing; and in addition, the bearing assembly improves the assembling efficiency and reliable quality of the steering device, and prolongs the service life of the bearing.
Description
Technical field
The utility model relates to the processing design field of bearing, especially relates to a kind of automobile steering device Bearing assembly of difficult drop-off.
Background technique
At present, this type of commutator because the inner ring and the outer ring of bearing sleeve do not have groove and do not carry out phosphatization processing etc., exists the problem that comes off in sulfuration back inner ring and outer ring and the bonding not firm use of rubber with Bearing assembly.While, the elastic caoutchouc bearing that is pressed into was axially unrestricted owing to the inner ring employing is barrel shaped structure, and meeting have a strong impact on the total quality of commutator because of the quality problems of misoperation generation rubber bush bearing and bearing sleeve disengaging during assembling.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of automobile steering device Bearing assembly, it can solve former bearing assembly parts exist bonding not firm and install and use in problem such as come off easily.
The technical scheme in the invention for solving the technical problem is: a kind of automobile steering device Bearing assembly, the elastic caoutchouc bearing that comprises bearing sleeve and bearing sleeve inside, bearing sleeve comprises outer ring and inner ring, outer ring and inner ring pass through rubber bound, described inner ring has an end band rib, and the other end riveting lock point after the elastic caoutchouc bearing is packed into is enclosed in the inner ring.
In order more to make the more firm of outer ring, inner ring and rubber bound, the outside relative position of the inside of described outer ring and inner ring respectively is provided with a circular groove, is embedded in the circular groove after the vulcanization of rubber.
In order to make Bearing assembly carrying and damping, described elastic caoutchouc bearing comprises rubber sleeve, and the inside of rubber sleeve is provided with retainer, and needle roller is installed on the retainer, is provided with the elasticity outer ring between retainer and rubber sleeve.
In order to prevent that with the inner ring close-fitting bearing from radially rotating, described rubber sleeve is provided with skeleton.
The beneficial effects of the utility model are: adopted and solved bearing sleeve inner ring and the outer ring comes off because of the sulfuration bonding is not firm and the elastic caoutchouc bearing comes off from bearing sleeve problem after the said structure, and improved the efficiency of assembling and the reliability quality of commutator, prolonged the working life of bearing.

Embodiment
A kind of as depicted in figs. 1 and 2 automobile steering device Bearing assembly, the elastic caoutchouc bearing that comprises bearing sleeve and bearing sleeve inside, bearing sleeve comprises outer ring 1 and inner ring 2, outer ring 1 and inner ring 2 are by rubber 3 bondings, described inner ring 2 one end band ribs, the other end is riveted behind the bearing of packing into the elastic caoutchouc bearing is enclosed in the inner ring 2; The outside relative position of the inside of described outer ring 1 and inner ring 2 respectively is provided with a circular groove, is embedded in the circular groove after rubber 3 sulfurations; Described elastic caoutchouc bearing comprises rubber sleeve 4, and the inside of rubber sleeve 4 is provided with retainer 5, and needle roller 6 is installed on the retainer 5, is provided with elasticity outer ring 7 between retainer 5 and rubber sleeve 4; Described rubber sleeve 4 is provided with skeleton 8.
Adopt inner ring 2 bottoms end formula, can prevent that the elastic caoutchouc bearing from deviating from.After being pressed into the elastic caoutchouc bearing, inner ring 2 oral areas in the bearing sleeve adopt the riveted joint mode, prevent that simultaneously the elastic caoutchouc bearing from deviating from from opposite side.After handling, outer ring 1 and inner ring 2 equal phosphatizations prevent that product from getting rusty.This kind Bearing Installation is firm, has reduced improper cause bad is installed in the installation process, not only makes Bearing Installation convenient and swift, has also improved the reliability of bearing quality.
The foregoing description limits all employings of the utility model never in any form and is equal to and replaces or technological scheme that the mode of equivalence conversion obtains all drops in the protection domain of the present utility model.
