Abstract
The utility model discloses an elastic rubber bearing. The elastic rubber bearing comprises an elastic ring, a roller pin, a retainer and a rubber outer sleeve, wherein the roller pin is kept in the retainer; the elastic ring is sleeved in an outer ring of the retainer and is contacted with the roller pin; retainer ring gaskets are arranged at the two sides of the retainer; the elastic ring, the roller pin, the retainer and the retainer ring gaskets are arranged inside the rubber outer sleeve; the outer diameter of the retainer ring gaskets is the same as the inner diameter of the rubber outer sleeve; the inner diameters of the retainer ring gaskets are the same as the inner diameter of the retainer. With the adoption of the manner, the abrasion between the retainer and the rubber outer sleeve can be eliminated and a pulling-out force of the retainer is enhanced; the problem that the retainer is released from the bearing due to improper operation in the mounting process of the bearing is solved; a phenomenon that a steering gear tubular column is scrapped or reworked is avoided, and the service life of a product is prolonged.
Description
Technical field
The utility model relates to bearing processing design field, especially relates to a kind of elastic caoutchouc bearing that is assemblied in the heavy-load automobile commutator that is applicable to.
Background technique
At present, in the general elastic caoutchouc needle bearing that automobile steering device is used, because metal retainer end face contacts with rubber sleeve, therefore bearing is in rotation, the rib of retainer end face and rubber sleeve is easy to generate friction, and especially bearing is because the generation of axial force causes the friction of retainer and rubber sleeve, the rubber sleeve rib is destroyed cause the retainer assembly to deviate to lose efficacy, shorten the life-span of bearing.Simultaneously because the rib rigidity deficiency of rubber sleeve, bearing in installation process because the quality problems that misoperation exists retainer to come off from rubber sleeve.Therefore especially heavy-load automobile is bigger because of the ejecting force of installation shaft, and the latency that retainer comes off is bigger, and the bearing of high-quality becomes the technical barrier that must solve for the client provides more how to improve life-span of bearing and reliability.
The model utility content
The technical problem that the utility model mainly solves provides a kind of elastic caoutchouc bearing, thereby can eliminate the quality problems that wearing and tearing between retainer and the rubber sleeve influence bearing life, and solve the installation question that retainer comes off from bearing because of misoperation in installation process, commutator after avoiding the connecting maintenance of doing over again has prolonged working life of product.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of elastic caoutchouc bearing is provided, comprise: elastic ring, needle roller, retainer and rubber sleeve, described needle roller remains in the retainer, described elastic ring is enclosed within the outer ring of retainer and contacts with needle roller, the both sides of described retainer are provided with the back-up ring pad, described elastic ring, needle roller, retainer and back-up ring pad all are built in rubber sleeve inside, the external diameter of described back-up ring pad is identical with the internal diameter of rubber sleeve, and the internal diameter of described back-up ring pad is identical with the internal diameter of retainer.
In preferred embodiment of the utility model, described back-up ring pad is the low carbon steel plate impact briquetting, and cost is low, efficiently solves the problem that comes off of retainer.
In preferred embodiment of the utility model, the external diameter of described elastic ring is identical with the internal diameter of rubber sleeve, has kept the external diameter surface of elastic ring and the inside diameter surface of rubber sleeve to fit tightly, and has good buffer function.
The beneficial effects of the utility model are: the utility model has adopted after the said structure, and the life-span of elastic caoutchouc bearing is improved, and has improved reliability in the bearing installation process, the problem that the retainer that solution client misoperation produces comes off; For the client provides all-round excellent product.Simultaneously also making me take charge of this type of bearing quality rises to a new step, has improved product competitive ability.
Description of drawings
Fig. 1 is the sectional structure schematic representation of the utility model elastic caoutchouc bearing one preferred embodiment.
The mark of each parts is as follows in the accompanying drawing: 1, elastic ring; 2, needle roller; 3, retainer; 4, rubber sleeve; 5, back-up ring pad.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, the utility model is embodiment comprise: a kind of elastic caoutchouc bearing, comprise: elastic ring 1, needle roller 2, retainer 3 and rubber sleeve 4, needle roller 2 remains in the retainer 3, elastic ring 1 is enclosed within the outer ring of retainer 3 and contacts with needle roller 2, the both sides of retainer 3 are provided with back-up ring pad 5, elastic ring 1, needle roller 2, retainer 3 and back-up ring pad 5 all are built in rubber sleeve 4 inside, the external diameter of back-up ring pad 5 is identical with the internal diameter of rubber sleeve, and the internal diameter of back-up ring pad is identical with the internal diameter of retainer.
Furtherly, described back-up ring pad 5 is the low carbon steel plate impact briquetting, and the external diameter of elastic ring 1 is identical with the internal diameter of rubber sleeve 4.
The utility model is different from prior art and improves internal structure at the rubber bush bearing of routine, set up back-up ring pad 4, separate retainer 3 and rubber sleeve 4, eliminated retainer 3 wearing and tearing to the rib of rubber sleeve 4 in rotation, improved the whole service life of bearing; Because the external diameter of back-up ring pad 4 greater than the external diameter of retainer 3, has increased retainer 3 and needle roller 2 assemblies needed withdrawal force in installation process, installation reliability is higher simultaneously.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
