Description
Technical field
The utility model relates to a kind of universal joint, especially relates to a kind of with roller pin gasket and the double-deck dust-proof universal joint of oil resistant rubber, nylon.
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, cause the working life of universal joint shorter.
Model utility content
The utility model is to provide a kind of with roller pin gasket and the double-deck dust-proof universal joint of oil resistant rubber, nylon, 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, cause the technical problem of shorter grade in the working life of universal joint.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Of the present utility model a kind of with roller pin gasket and the double-deck dust-proof universal joint of oil resistant rubber, nylon, comprise cross axle, the axle body of described cross axle is socketed with outer ring, needle roller is provided with between cross axle and outer ring, needle roller is two-row structure, first grade of axle journal step place of cross axle is provided with metal frame, metal frame is provided with rubber oil sea, the third gear axle journal step place of cross axle is provided with nylon dust-proof cover, the interior Transverse plane of cross axle third gear axle journal step end and outer ring is close in the both sides of nylon dust-proof cover, and cross axle is provided with oil nozzle.Needle roller adopts two-row structure, makes it roll flexibly, and the effect of radial envelope born by oil sealing.Dust-proof cover 6 is nylon part, and its internal diameter interference is contained on cross axle third gear axle journal step, makes its fully anti-muddy water, dust enters in bearing, increases the working life of universal joint assembly.The section of nylon dust-proof cover can be C font.
As preferably, be provided with wear-resistant gasket between described outer ring and cross-member ends, the cylindrical of wear-resistant gasket is located between outer ring and needle roller, and the height of wear-resistant gasket cylindrical is higher than the height in the middle part of wear-resistant gasket.Wear-resistant gasket can prevent cross axle, needle roller directly contacts outer ring, serves wear-resisting effect.
As preferably, the internal diameter teeth portion radial direction of described rubber oil sea is close to the second gear axle journal step place of cross axle, seals comparatively complete like this.
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 the working life of whole universal joint is longer, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is I portion structure for amplifying schematic diagram of Fig. 1.
