Description
Technical field
The utility model relates to a kind of universal joint assembly, especially relates to a kind of labyrinth sealing Hooke's joint assembly.
Background technique
Universal-joint cross trunnion of the prior art, generally all forms by middle axis body and with the arm that middle axis body links into an integrated entity.Chinese patent discloses a kind of high-strength universal joint (Authorization Notice No.: CN 2464984Y), it comprises cross axle and the needle roller that is arranged on around cross axle spindle nose and putting and the outer ring outside needle roller, the end of outer ring is provided with packing holder, and packing holder is provided with seal ring skeleton and seal placed on it; And the inner side of seal is provided with tilting outer lip and the inside middle lip of lip and inner lip successively, three lips contact with the axle journal of cross axle; The grinding undercut of annular is tiltedly provided with between internal face and needle roller end face ring, and needle roller end face ring is in the same plane with the cross axle spindle nose end face be placed in inside needle roller, the inner side of needle roller end face ring is provided with pad chamber, it is built-in with fiber nylon Composition spacer, and the exterior edge face of Composition spacer flushes substantially with needle roller end face ring; The center line of grinding undercut and bottom plane, outer ring are 35 ° ~ 55 ° angles, and its degree of depth is 0.25 ~ 0.6mm, the circular arc ring of to be radius be in end 0.3 ~ 5.Omm.But the anti-dust performance of this universal joint is poor, during driving, dust or muddy water easily enter into Bearing inner, and as added the rotation that dust guard then can affect outer ring.
Model utility content
The utility model is to provide a kind of labyrinth sealing Hooke's joint assembly, its anti-dust performance mainly solving the universal joint existing for prior art is poor, during driving, dust or muddy water easily enter into Bearing inner, and as added the technical problem that dust guard then can affect the rotation of outer ring etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Labyrinth sealing Hooke's joint assembly of the present utility model, comprise cross axle, the axle body of described cross axle is socketed with outer ring, is provided with needle roller between cross axle and outer ring, the axle journal place of cross axle is provided with axle bowl, the section of axle bowl is C font, the inner of outer ring is provided with cover bowl, and the section of cover bowl is zigzag, is provided with oil sealing in it, the inner of cover bowl extend in the cavity of axle bowl, and the centre of cross axle is provided with oil nozzle.Cover bowl, axle bowl all adopt 08 or the manufacture of 08F carbon constructional quality steel.By oil-sealing sleeve in the inner ring of cover bowl, and roll extrusion is on the outer round recessed of outer ring mouth plane.Axle bowl internal diameter, by interference fit, is fastened on cross axle step axle journal.During such driving, dust or muddy water just can will enter in bearing rounding gulf, a few road, good dustproof effect.
As preferably, between described outer ring and cross-member ends, be provided with wear-resistant gasket, can prevent cross-member ends from directly to wear and tear outer ring like this, reach wear-resisting effect.
As preferably, the inner outer surface of described outer ring is provided with groove, and the outer end punching press of cover bowl, in groove, is assembled comparatively firm like this.
As preferably, contact with axle bowl in the cavity that the inner of described cover bowl extend into axle bowl, the oil sealing overlapped on bowl has 2 sealing lips, the axle journal of sealing lip ends contact cross axle.Because outer ring does not contact all the time with axle bowl, without any obstruction, therefore outer ring rotates comparatively flexible.
Therefore, anti-dust performance of the present utility model is better, and during driving, dust or muddy water are not easy to enter into Bearing inner, and does not contact all the time with axle bowl due to outer ring, can not affect the rotation of outer ring, simple and reasonable for structure.
