Description
Technical field
The utility model relates to a kind of universal joint, especially relates to a kind of universal joint with the double needle roller of nylon spacer.
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 universal joint with the double needle roller of nylon spacer, 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:
A kind of universal joint with the double needle roller of nylon spacer of the present utility model, comprise cross axle, the axle body of described cross axle is socketed with outer ring, be provided with needle roller between cross axle and outer ring, needle roller is two-row structure, and the inner of outer ring is pressed with metal frame, metal frame is provided with rubber oil sea, be provided with nylon spacer between outer ring and cross-member ends, the cylindrical of nylon spacer is located between outer ring and needle roller, and the height of nylon spacer cylindrical is higher than the height in the middle part of nylon spacer.Bottom the internal diameter of outer ring, nylon spacer is housed, nylon spacer is and trunnion journal end contact, and mainly in order to reduce the rotating friction force of trunnion journal end face, anti-heating, extends the working life of trunnion journal end face.The internal diameter of rubber oil sea is close to trunnion journal step with grease proofing leakage, axially compresses into outer ring, makes to be close to nylon spacer between double needle roller, makes bearing when assembling cross axle, not easily falls pin.
As preferably, between the inner of described outer ring and trunnion journal, be provided with dust-proof cover, in metal frame, rubber oil sea are sealed in by dust-proof cover.
As preferably, form a plane recess between described outer ring interior edge face and metal frame, the internal diameter of dust-proof cover is provided with lug boss, and lug boss is held in plane recess.Dust-proof cover internal diameter high spot is held in outer ring mouth plane recess, in case outside muddy water enters Bearing inner, oil sealing, dust-proof cover double-layer seal, increase the service life.
As preferably, between described double needle roller, be provided with pad.Double needle roller increases flexibility of revolution, separates between needle roller with pad, is also the wearing and tearing and the heating that reduce needle roller.
As preferably, described rubber oil sea has 3 sealing lips, and the axle journal place of sealing lip contact cross axle, seals comparatively complete like this.
As preferably, described cross axle is socketed with aerofoil profile bearing.Outer ring and aerofoil profile bearing are symmetrical arranged between two.
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 frictional force of whole universal joint is less, anti-heating, and working life is longer, simple and reasonable for structure.
