Abstract
The invention 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, and the elastic ring is sleeved on an outer ring of the retainer and can contact with the roller pin; the two sides of the retainer are provided with check ring gaskets, and the elastic ring, the roller pin, the retainer and the check ring gaskets are arranged in the rubber outer sleeve; and the external diameters of the check ring gaskets are same with the inner diameter of the rubber outer sleeve, and the inner diameters of the check ring gaskets are same with the inner diameter of the retainer. Through the manner, the elastic rubber bearing provided by the invention can eliminate the abrasion between the retainer and the rubber outer sleeve, the withdrawal force of the retainer is enhanced, the problem that a bearing falls off from the retainer due to improper operation in the installation process is solved, the tubular column scrap or rework maintenance of a steering gear is avoided, and the service life of a product is prolonged.
Description
Technical field
The present invention relates to the bearing machining design field, especially relate to a kind of elastic caoutchouc bearing for the commutator of assembling heavy-load automobile.
Background technique
At present, in the general elastic caoutchouc needle bearing that automobile steering device is used, because the metal cage end face contacts with rubber sleeve, therefore bearing is in rotation, the rib of retainer end face and rubber sleeve easily produces friction, and especially bearing due to 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.Rib rigidity due to rubber sleeve is not enough simultaneously, the quality problems that bearing exists retainer to come off from rubber sleeve due to misoperation in installation process.Therefore especially heavy-load automobile is larger because of the ejecting force of installation shaft, and the latency that retainer comes off is larger, and the bearing of high-quality becomes the technical barrier that must solve for the client provides more how to improve the life and reliability of bearing.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of elastic caoutchouc bearing, thereby can eliminate the quality problems that wearing and tearing between retainer and rubber sleeve affect 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 extended working life of product.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of elastic caoutchouc bearing is provided, comprise: elastic ring, needle roller, retainer and rubber sleeve, described needle roller remains in 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 a preferred embodiment of the present invention, 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 a preferred embodiment of the present invention, 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 invention has the beneficial effects as follows: after the present invention has adopted said structure, be improved in the life-span of elastic caoutchouc bearing, 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 kind of bearings is raised to qualitatively a new step, has improved product competitive ability.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of elastic caoutchouc bearing one preferred embodiment of the present invention.
In accompanying drawing, the mark of each parts is as follows: 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 invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the present invention comprises: a kind of elastic caoutchouc bearing, comprise: elastic ring 1, needle roller 2, retainer 3 and rubber sleeve 4, needle roller 2 remains in 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 present invention is different from prior art and improves internal structure on the rubber bush bearing of routine, sets up back-up ring pad 4, separate retainer 3 and rubber sleeve 4, has eliminated retainer 3 wearing and tearing to the rib of rubber sleeve 4 in rotation, has improved the whole service life of bearing; Simultaneously due to the external diameter of back-up ring pad 4 external diameter greater than retainer 3, increased retainer 3 and needle roller 2 assemblies needed withdrawal force in installation process, installation reliability is higher.
The above is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
