Abstract
The invention relates to a universal joint of a long-life wear-resisting stamping bearing structure. The universal joint comprises a second stamping bearing outer ring, a second roller pin, a second oil sealing framework and a second oil seal, wherein an inner ring of the stamping bearing outer ring is sequentially assembled with a nylon spacer, the second roller pin, the second oil sealing framework and the second oil seal, and the nylon spacer is positioned at the bottom part of the stamping bearing outer ring; an outer ring of the stamping bearing outer ring is clamped with a clamp spring, and the clamp spring is tightly clamped with the second oil seal; the opening part of the stamping bearing outer ring is provided with a dust cover, and the dust cover is attached to the clamp spring; and an outer lip of the dust cover is in interference fit with the opening part of the stamping bearing outer ring. The universal joint disclosed by the invention has the beneficial effects that after the universal joint of the long-life wear-resisting stamping bearing structure is used, the service life of a transmission shaft universal joint is obviously prolonged, the transmission shaft universal joint can even reach the same service life with a whole vehicle, and three-guarantee cost of a transmission shaft assembly in the size is reduced to a large extent by more than 50%.
Description
Technical field
The present invention relates to the universal joint field, mainly is a kind of universal joint of long-life abrasion-resistant impulse bearing structure.
Background technique
The impulse bearing of the universal joint assembly that former transmission shaft adopts is the structure of accompanying drawing 1, is comprised of the first impulse bearing outer ring 8, the first needle roller 9, the first oil tight skeleton 10, the first oil sealing 11.After the first needle roller 9 in the bearing and 11 assemblings of the first oil sealing are finished, have certain gap between the first needle roller 9 and the first oil sealing 11, cause universal joint assembly in use, the first needle roller 9 easily produces axial float or crooked, unstable wear, the working life of reducing universal joint.Universal joint is after being assembled to transmission shaft fork part, because the first impulse bearing outer ring 8 walls are thin, and easily distortion, the first oil sealing 11 is easily deviate from the first impulse bearing outer ring 8 after the assembling, causes oil impregnate, leakage of oil in the transmission shaft use.The lubricating grease of universal joint assembly and outside dust, muddy water all are that the oil sealing by one or three lips seals.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and a kind of universal joint that resists the long-life abrasion-resistant impulse bearing structure wear-resisting, that performance is good is provided.
The objective of the invention is to finish by following technical solution, it comprises the second impulse bearing outer ring, the second needle roller, the second oil tight skeleton, the second oil sealing, the inner ring of described impulse bearing outer ring is equipped with nylon spacer, the second needle roller, the second oil tight skeleton and the second oil sealing successively, and nylon spacer is positioned at the bottom of impulse bearing outer ring; The outer ring of impulse bearing outer ring has snapped in jump ring, and this jump ring is clamped in the second oil sealing.
As preferably, the oral area of described impulse bearing outer ring is provided with dust-proof cover, and this dust-proof cover is affiliated on jump ring; The oral area of the outer lip of dust-proof cover and impulse bearing outer ring is interference fit.
Beneficial effect of the present invention is: after using the universal joint of this long-life abrasion-resistant impulse bearing structure, significantly increase the working life of shaft universal-joint, even can reach and the same life-span of car load, significantly reduces this specification driving-shaft assembly three guarantees expense more than 50%.
Description of drawings
Fig. 1 is the structural representation of the impulse bearing of the universal joint assembly that adopts of former transmission shaft.
Fig. 2 is structural representation of the present invention.
Label in the accompanying drawing is respectively: 1, dust-proof cover; 2, jump ring; 3, the second oil sealing; 4, the second oil tight skeleton; 5, the second needle roller; 6, nylon spacer; 7, impulse bearing outer ring; 8, the first impulse bearing outer ring; 9, the first needle roller; 10, the first oil tight skeleton; 11, the first oil sealing; 12, outer lip.
Embodiment
Below in conjunction with accompanying drawing the present invention is done detailed introduction: as shown in Figure 2, the present invention includes the second impulse bearing outer ring 7, the second needle roller 5, the second oil tight skeleton 4, the second oil sealing 3, the inner ring of described impulse bearing outer ring 7 is equipped with nylon spacer 6, the second needle roller 5, the second oil tight skeleton 4 and the second oil sealing 3 successively, and nylon spacer 6 is positioned at the bottom of impulse bearing outer ring 7; Increase nylon spacer 6 in the bottom of impulse bearing outer ring 7, prevent cross axle and 7 bottoms, the impulse bearing outer ring generation high temperature that directly weares and teares, both can stop the cross axle axial float after the wearing and tearing, high temperature that again can the wear prevention generation is on the impact of bearing.The outer ring of impulse bearing outer ring 7 has snapped in jump ring 2, and this jump ring 2 is clamped in the second oil sealing 3; By jump ring 2, on the one hand can be spacing, prevent that the second oil sealing 3 from deviating from the second impulse bearing outer ring 7; Apply certain pretightening force at the second oil sealing 3 and the second needle roller 5 on the other hand, prevent the second needle roller 5 axial floats or crooked, improve polishing machine.
The oral area of described impulse bearing outer ring 7 is provided with dust-proof cover 1, and this dust-proof cover 1 is affiliated on jump ring 2; Have certain pretightening force, the outer lip 12 of dust-proof cover 1 is interference fit with the oral area of impulse bearing outer ring 7.In use, can effectively prevent the intrusion of dust and muddy water, internal lubrication fat seals by the second oil sealing 3.
The present invention is not limited to above-mentioned mode of execution, no matter do any variation in its shape or material formation, every employing structural design provided by the present invention all is a kind of distortion of the present invention, all should think within protection domain of the present invention.
