Abstract
The utility model relates to a universal joint, in particular to a cross universal joint with an integral oil seal, which is mainly used for solving the technical problems that needle roller check rings and the inner oil seal of a universal joint in the prior art are separately manufactured, and when in assembly, the check ring is added firstly and then the oil seal is pressed in, which causes relatively complicated processes, relatively high manufacturing cost and the like. The cross universal joint comprises a cross (1); the four ends of the cross are provided with a shaft sleeve (2) respectively; a needle roller (3) is arranged between the shaft sleeves (2) and the cross (1) respectively. The cross universal joint is characterized in that a step is arranged at the inner end of each shaft sleeve (2); a needle roller check ring (4) is clamped on the step; each needle roller check ring has an L-shaped section; and inner oil seals (5) are arranged between the needle roller check rings and the body of the cross (1).
Description
Technical field
The utility model relates to a kind of universal joint, especially relates to a kind of Hooke's joint with the integral type oil sealing.
Background technique
Universal-joint cross trunnion of the prior art is generally all formed 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 Hooke's joint (notice of authorization number: CN 2464984Y), it comprises cross axle and is arranged on the needle roller around the cross axle spindle nose and puts and outer ring that needle roller is outer, the end of outer ring is provided with packing holder, is provided with seal ring skeleton and seal placed on it on described packing holder; And the inboard of described seal is provided with tilting outer lip and inside middle lip and the inner lip of lip successively, and three lips contact with the axle journal of cross axle; Tiltedly be provided with the grinding undercut of annular between internal face and the needle roller end face ring, and the needle roller end face ring with place the cross axle spindle nose end face of needle roller inboard in the same plane, the inboard of needle roller end face ring is provided with the pad chamber, it is built-in with glass nylon Composition spacer, and the exterior edge face of Composition spacer flushes substantially with described 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, and the end is the circular arc ring that radius is 0.3～5.Omm.But the needle roller back-up ring of this universal joint and inner oil seal need to add earlier back-up ring for being separately made when assembling, oil sealing is suppressed into again, and operation is comparatively numerous and diverse, and manufacture cost is higher.
The model utility content
The utility model provides a kind of Hooke's joint with the integral type oil sealing, it mainly is to solve the needle roller back-up ring of existing in prior technology universal joint and inner oil seal for being separately made, when assembling, need to add earlier back-up ring, again oil sealing is suppressed into, operation is comparatively numerous and diverse, the technical problem that manufacture cost is more high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The Hooke's joint of band integral type oil sealing of the present utility model, comprise cross axle, four ends of cross axle are provided with axle sleeve, be provided with needle roller between axle sleeve and the cross axle, the inner of described axle sleeve is provided with step, be connected with the needle roller back-up ring on the step, the section of needle roller back-up ring is " L " type, is provided with inner oil seal between needle roller back-up ring and the cross axle axis body.Inner oil seal is located at the needle roller back-up ring inside of " L " type, so inner oil seal and needle roller back-up ring make one, makes can replace oil sealing and needle roller back-up ring to separate the cross axle of assembling in its mechanism, and has saved cost greatly, has reduced the multiple tracks assembly process.A checkpost of " L " type needle roller back-up ring is connected on the inner place of axle sleeve, and another side bumper is between needle roller and inner oil seal.
As preferably, the inner of described needle roller back-up ring is outward extended with the flange of being close to the cross axle axis body.The outer surface of flange has the conical surface, and it can insert the slit between needle roller end and the cross axle axis body, and the conical surface of the tapering of the conical surface and needle roller end needle point adapts.
As preferably, be provided with oil-return groove between the root of described cross axle and the cross axle axis body, the section of oil-return groove is a circular arc.After universal joint rotated, grease was done in oil-return groove and is circulated, and plays the effect of sealing, needle roller and the long-time particulate matter that produces of cross axle axis body friction can be back in the oil-return groove to be stored, thereby reduce the frictional force of working surface, so the water proofing property of grease has relatively high expectations, inner oil seal only need prevent dust.
As preferably, the internal surface of described axle sleeve outer end is provided with oil storage tank, and grease can exist in the oil storage tank, can play lubricated effect, can help the needle roller rotation.
Therefore, the utility model is made one with the inner oil seal and the needle roller back-up ring of cross axle root, settles at one go during assembling, has saved the multistep assembly process, has saved cost greatly, and effect as Hooke's joint, simple and reasonable for structure.
