Abstract
The utility model relates to a universal joint with a long-service-life wear-resisting structure. The universal joint comprises a universal joint pin and stamping bearings, wherein the necks of the universal joint pin are sleeved with quill rollers, the stamping bearings are mounted on the necks of the universal joint pin, and the bottoms of the stamping bearings are in contact with the end faces of necks of the universal joint pin. A small step is arranged at the bottom of each stamping bearing and provided with a plurality of groove points, and small bosses are arranged on the end faces of the four necks of the universal joint pin and provided with a plurality of protruding points. The width of each protruding point is larger than the width of each groove point. The universal joint with the long-service-life wear-resisting structure has the advantages that the service life of the universal joint of a transmission shaft is obviously prolonged, and the three-guarantee cost of the transmission shaft assembly of the specification is greatly lowered by more than 30%.
Description
Technical field
The utility model relates to the universal joint field, is mainly a kind of universal joint of long-life abrasion-resistant structure.
Background technique
The impulse bearing 2 of the universal joint assembly that former transmission shaft adopts and the structure that cross axle 1 structure is respectively accompanying drawing 1,2,3.Former impulse bearing 2 structure bottom planes are a smooth disk, former cross axle 1 structure is that inside middle is got through two oil channel holes 14, and mill three oil grooves 15 on the end face of axle journal 11, after impulse bearing 2 is assemblied on cross axle 1, the lubricating grease of universal joint inside is by the oil channel hole 14 of cross axle 1, the oil groove 15 of axle journal 11 end faces, thus needle roller 3 places arrived.Shortcoming is that grease flow is to passing through oil groove 15 two ends of axle journal 11 end faces, arrive needle roller 3 places near oil groove 15, diffusion covers the whole circle needle roller 3 on axle journal 11 gradually again, that the cross axle 1 axle journal 11 end faces plane of not slotting contacts with impulse bearing 2 bottom planes in addition, two interplanars do not have grease lubrication, while using when shaft universal-joint, easily cause dry grinding, high temperature, wearing and tearing, cause the universal joint looseness, the transmission shaft abnormal sound.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and the universal joint of the long-life abrasion-resistant structure that increases a kind of working life, cuts down finished cost is provided.
The purpose of this utility model completes by following technical solution, it comprises cross axle and impulse bearing, on the axle journal of described cross axle, cover has needle roller, this impulse bearing to be loaded on the axle journal of described cross axle, and the bottom of impulse bearing contacts with the end face of trunnion journal.
As preferably, described impulse bearing bottom is provided with a small stair, in this small stair upper punch, is pressed with several groove points.
As preferably, the end face of four axle journals of described cross axle is provided with small boss, and several salient points are arranged on this small boss; The width of this salient point is greater than the width of groove point.
The beneficial effects of the utility model are: this new structure not only can be comprehensive to the surrounding lubrication quill, and can lubricate contacted impulse bearing and cross axle small boss, prevent that both from dry grinding causing high temperature, improve polishing machine, extend the working life of universal joint; In addition the processing of cross axle with originally compared, cancelled the brill oil channel hole, milled the oil groove operation, reduced processing cost; After using the universal joint of this long-life abrasion-resistant 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 30%.

Embodiment
Below in conjunction with accompanying drawing, the utility model is done to detailed introduction: as shown in accompanying drawing 4,5,6,7,8, the utility model comprises cross axle 1 and impulse bearing 2, on the axle journal 11 of described cross axle 1, cover has needle roller 3, this impulse bearing 2 is loaded on the axle journal 11 of described cross axle 1, and the bottom of impulse bearing 2 contacts with the end face of cross axle 1 axle journal 11.Described impulse bearing 2 bottoms are provided with a small stair 21, in these small stair 21 upper punches, are pressed with several groove points 22.The end face of four axle journals 11 of described cross axle 1 is provided with small boss 12, and several salient points 13 are arranged on this small boss 12; The width of this salient point 13 is greater than the width of groove point 22.
By this internal structure is optimized to innovative design, the structure that the impulse bearing of novel universal joint assembly is accompanying drawing three, the structure that cross axle is accompanying drawing four.Stamp out a high HA on new impulse bearing 2 bottom planes, the small stair 21 of diameter of phi B, and stamp out the groove point one by one 22 that is regular distribution on small stair 21.On new cross axle 1 axle journal 11 end faces, process equally a high HC, the small boss 12 of diameter of phi D, and process the salient point one by one 13 that is regular distribution on small boss 12, the groove point 22 of impulse bearing 2 is smaller than the salient point of cross axle 1 13, and both regular distribution are different, after new like this impulse bearing 2 is assemblied on new cross axle 1, there is the gap of HA+HC between axle journal 11 end faces of the bottom plane of impulse bearing 2 and cross axle 1, this gap is used for storing lubricating grease, therefore this new structure not only can be comprehensive to surrounding lubrication quill 3, and can lubricate contacted impulse bearing 2 and cross axle 1 small boss 12, prevent that both from dry grinding causing high temperature, improve polishing machine, extend the working life of universal joint.In addition the processing of cross axle 1 with originally compared, cancelled the brill oil channel hole, milled the oil groove operation, reduced processing cost.
The utility model is not limited to above-mentioned mode of execution; no matter do any variation on its shape or material formation; every employing structural design provided by the utility model, be all a kind of distortion of the present utility model, all should think within the utility model protection domain.
