Abstract
The utility model relates to a universal joint with a long-life wear-resistant stamping bearing structure. The universal joint comprises a second stamping bearing outer ring, a second rolling needle, a second oil seal framework and a second oil seal, wherein an inner ring of the stamping bearing outer ring is provided with a nylon gasket, a second rolling needle, a second oil seal framework and a second oil seal in sequence; the nylon gasket is positioned at the bottom of the stamping bearing outer ring; a clamping spring is clamped in an outer ring of the stamping bearing outer ring; the clamping spring is clamped to the second oil seal; an opening part of the stamping bearing outer ring is provided with a dustproof cover; the dustproof cover is hung on the clamping spring; and an outer lip opening of the dustproof cover is in interference fit with the opening part of the stamping bearing outer ring. The universal joint has the benefits as follows: after the universal joint with the long-life wear-resistant stamping bearing structure is used, the service life of a transmission shaft universal joint is remarkably prolonged and even can reach the same service life as the whole vehicle, and the after-sales expense of a transmission shaft assembly can be greatly reduced.
Description
Technical field
The utility model 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 made up of the first impulse bearing outer ring 8, first needle roller 9, first oil tight skeleton 10, first oil sealing 11.After first needle roller 9 in the bearing and 11 assemblings of first oil sealing are finished, have certain clearance between first needle roller 9 and first oil sealing 11, cause universal joint assembly in use, first needle roller 9 is easy to generate axial float or crooked, the aggravation wearing and tearing, 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 easy deformation, assembling back first oil sealing 11 is deviate from the first impulse bearing outer ring 8 easily, 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 purpose of this utility model 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 purpose of this utility model is finished by following technical solution, it comprises the second impulse bearing outer ring, second needle roller, second oil tight skeleton, second oil sealing, the inner ring of described impulse bearing outer ring is equipped with nylon spacer, second needle roller, second oil tight skeleton and 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 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.
The beneficial effects of the utility model are: after using the universal joint of this long-life abrasion-resistant impulse bearing structure, significantly increase the working life of transmission shaft universal joint, even can reach and the same life-span of car load, significantly reduce 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 utility model.
Label in the accompanying drawing is respectively: 1, dust-proof cover; 2, jump ring; 3, second oil sealing; 4, second oil tight skeleton; 5, second needle roller; 6, nylon spacer; 7, impulse bearing outer ring; 8, the first impulse bearing outer ring; 9, first needle roller; 10, first oil tight skeleton; 11, first oil sealing; 12, outer lip.
Embodiment
Below in conjunction with accompanying drawing the utility model is done detailed introduction: as shown in Figure 2, the utility model comprises the second impulse bearing outer ring 7, second needle roller 5, second oil tight skeleton 4, second oil sealing 3, the inner ring of described impulse bearing outer ring 7 is equipped with nylon spacer 6, second needle roller 5, second oil tight skeleton 4 and 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, the high temperature of the generation that can prevent from again wearing and tearing is to the influence 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 second oil sealing 3; By jump ring 2, on the one hand can be spacing, prevent that second oil sealing 3 from deviating from the second impulse bearing outer ring 7; Apply certain pretightening force at second oil sealing 3 and second needle roller 5 on the other hand, prevent 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 second oil sealing 3.
The utility model 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 utility model all is a kind of distortion of the present utility model, all should think within the utility model protection domain.
