Description
Technical field
The utility model is related to a kind of Hooke's joint, and high torque Hooke's joint is born more particularly, to one kind.
Background technology
Universal-joint cross trunnion of the prior art, is typically all to be linked into an integrated entity by middle axis body and with middle axis body
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 the outer ring wall thickness of this Hooke's joint is thicker, the diameter of needle roller
Smaller or needle roller negligible amounts, therefore the bearing capacity of whole bearing is smaller, it is impossible to applied in the vehicle of high pulling torque.
Utility model content
The utility model is to provide one kind and bears high torque Hooke's joint, and it is mainly present in solution prior art
Hooke's joint outer ring wall thickness it is thicker, the diameter of needle roller is smaller or negligible amounts of needle roller, therefore whole bearing
Bearing capacity is smaller, it is impossible to the medium technical problem of vehicle applied to high pulling torque.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
One kind of the present utility model bears high torque Hooke's joint, including cross shaft body, described cross axle sheet
The axis body of body is socketed with outer ring, double needle roller is provided between outer ring and axis body, the wall thickness of outer ring is 2-2.5mm, cross axle sheet
The middle part of body is provided with oil nozzle, and sealing mechanism is provided between the axis body root of cross shaft body and outer ring the inner.The utility model exists
Under equal special case, the wall thickness dimension of outer ring is designed than conventional collar wall thickness, the big torsion in vehicle is so can adapt to
Square, with top load.
Preferably, the axis body root of described cross shaft body is provided with the shoulder of multilayer, shoulder is by multiple arc chord angle groups
Into.Double R angles design of multiple field shoulder, can effectively increase cross axle bearing capacity.
Preferably, described sealing mechanism includes the first metalwork that section is L-type and the second gold medal that section is c-type
Belong to part, the first metalwork is provided with first seal, and first seal contact shoulder, the second metalwork is sealed provided with second
Part, the side contact shoulder of second seal, the opposite side of second seal is provided with sealing lip, and sealing lip is contacted in the first metal
On part, the end part seal of second seal is on outer ring.The design of multi-sealed part, ensure that whole Hooke's joint
Sealing, prevents dust from invading.
Preferably, being provided with needle roller back-up ring between the first described metalwork and the end face of needle roller.Can by needle roller back-up ring
To cause sealing mechanism, needle roller that there is certain cushion effect, anti-dust performance can be so remained.
Therefore, the utility model is by reducing outer ring wall thickness, increase needle roller diameter or increase needle roller quantity, it is possible to increase
The bearing capacity of bearing, while using the design of multiple field shoulder, effectively increasing moment of torsion, can prevent ash with multi-sealed in addition
Dirt is invaded, and further increases moment of torsion, simple and reasonable for structure.
