Arm is constituted.Chinese patent discloses a kind of high-strength universal joint（Authorization Notice No.：CN 2464984Y）, it includes ten
Word axle and the needle roller being arranged on around cross axle spindle nose and put and be provided with packing holder with the outer ring outside needle roller, the end of outer ring,
Provided with sealing ring framework and seal placed on it on packing holder；And tilting outer lip is sequentially provided with the inside of seal
Mouth and lip inside middle lip and inner lip, three lips are in contact with the axle journal of cross axle；Internal face and needle roller end face ring it
Between grinding undercut tiltedly provided with annular, and needle roller end face ring and the cross axle spindle nose end face that is placed on the inside of needle roller are in same plane
On, the inner side of needle roller end face ring is provided with pad chamber, and it is built-in with fiber nylon Composition spacer, and outer face and the rolling of Composition spacer
Pin end face ring is substantially flush；The center line of grinding undercut is with outer ring baseplane in 35 °~55 ° angles, and its depth is 0.25~0.6mm,
End is in the circular arc ring that radius is 0.3~5.Omm.But this Hooke's joint is in use, needle roller will be produced
It can be collided during axial motion, vibration with the diameter of axle root of cross axle and oil sealing, and cause joint failure.
Utility model content
The utility model is to provide a kind of Hooke's joint with buffer-type needle roller back-up ring, and it is existing that it is mainly solution
In use, needle roller will produce meeting and cross during axial motion, vibration to Hooke's joint present in technology
The diameter of axle root of axle and oil sealing collide, and cause the technical problem of joint failure etc..
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
A kind of Hooke's joint with buffer-type needle roller back-up ring of the present utility model, including cross shaft body, it is described
The axis body of cross shaft body be socketed with outer ring, double needle roller, the axis body root of cross shaft body are provided between outer ring and axis body
Sealing mechanism is provided between portion and outer ring are inner, needle roller back-up ring is provided between sealing mechanism and the end face of needle roller.Needle roller back-up ring is kept off
Between needle roller and sealing mechanism, so effectively it can prevent needle roller from beating, it is ensured that the operation of Hooke's joint.
Preferably, described needle roller back-up ring is splayed, it is 65Mn spring steel needle roller back-up rings.Splayed can be played
The effect of buffering.Splayed needle roller collar material uses 65Mn spring steel, and when axial motion occurs for needle roller in bearing, it will
Play the axial motion power of reduction needle roller, it is ensured that the service life of product.
Preferably, described sealing mechanism includes, section is corrugated first metalwork and section is J-type
Second metalwork, the second metalwork is located at the inner of the first metalwork, and the first metalwork is provided with the first oil sealing, the first oil sealing
Two sealing lips contact axis body root and the inner surface of cross shaft body respectively, and the second metalwork is provided with the second oil sealing,
The axis body root of second oil sealing end thereof contacts cross shaft body, another end in contact outer ring of the second oil sealing outer surface.By dual close
Envelope, it is ensured that dust is entered inside universal joint, so as to ensure the even running of universal joint.
Preferably, the surfaces externally and internally of described outer ring end is all provided with locating slot.Can be for positioning by locating slot
First oil sealing, the second oil sealing, can so prevent it from coming off.
Therefore, the utility model is designed with needle roller back-up ring between needle roller and set oil sealing, when needle roller occurs axially in bearing
During vibration, it will play the axial motion power of reduction needle roller, it is ensured that the service life of product, simple and reasonable for structure.
