Abstract
The invention discloses a kind of high-mechanic long-life Hooke's joints, it mainly include cross axle, outer ring, needle roller, sealing ring, u font groove, design has u font groove on four axle journals of cross axle, needle roller is installed in u font groove, it is set with outer ring outside needle roller, sealing ring is installed to seal needle roller between outer ring and the axle journal of cross axle.The present invention is designed by u font groove, increases effectively needle roller and trunnion journal contact area, improves the oil storage capacity of journal surface, so that needle roller and trunnion journal contact stress is reduced by 20% or more, bearing fatigue life improves 15% or more.
Description
Technical field
The present invention relates to the fields of universal joint, and in particular to a kind of high-mechanic long-life Hooke's joint.
Background technique
When cross axle operates, especially under severe duty, needle roller and journal contact stress are larger, and needle roller is in cross axle axis
It swings back and forth between neck, outer ring, revolution motion will not occur along axle journal, will cause trunnion journal and early fatigue peeling occurs.
Its basic reason is that needle roller and trunnion journal contact stress are larger.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of high-mechanic long-life cross axle ten thousand
Xiang Jie.
The object of the present invention is achieved by the following technical solutions: this high-mechanic long-life Hooke's joint,
It mainly include cross axle, outer ring, needle roller, sealing ring, u font groove, design has u font groove, u on four axle journals of cross axle
Needle roller is installed in font groove, is set with outer ring outside needle roller, sealing ring is installed to seal needle roller between outer ring and the axle journal of cross axle.
The u font groove be it is arc-shaped, make the contact form " convex to recessed " of needle roller and trunnion journal.
The u font groove quantity is identical as needle roller.
The invention has the benefit that
1, the present invention is rolled under the premise of not changing cross axle outer dimension, not influencing bearing movable performance by increasing
Contact area, reduction contact stress between needle and axle journal, to achieve the purpose that improve the Hooke's joint service life.
2, the present invention is designed by u font groove, is increased effectively needle roller and trunnion journal contact area, is improved axis
The oil storage capacity on neck surface makes needle roller and trunnion journal contact stress reduce by 20% or more, and bearing fatigue life improves 15%
More than.

Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
Embodiment: as shown in the picture, this high-mechanic long-life Hooke's joint, mainly include cross axle 1, outer ring 2,
Needle roller 3, sealing ring 4, u font groove 5, design has u font groove 5, installation in u font groove 5 on four axle journals of cross axle 1
Needle roller 3, needle roller 3 are set with outer ring 2 outside, and sealing ring 4 is installed between outer ring 2 and the axle journal of cross axle 1 to seal needle roller 3.U font is recessed
Slot 5 be it is arc-shaped, so that needle roller 3 and the contact form of 1 axle journal of cross axle is changed to " convex to recessed " by " convex to convex ", can effectively increase
Contact area.Meanwhile u font groove 5 can also improve the ability of journal surface storing lubricating grease, enhance bearing lubrication performance.Through
It calculates, contact area increases 25% or more, and contact stress reduces by 20% or more, and bearing life can be made to improve 15% or more.U word
5 quantity of connected in star is identical as needle roller 3.5 depth of u font groove is determined according to specific operating condition, specific structure.The present invention does not change axis
Movenent performance is held, bearing size is not changed.
It is understood that it will be understood by those skilled in the art that being subject to technical solution of the present invention and inventive concept
It all should fall within the scope of protection of the appended claims of the present invention with replacement or change.
