Description
Technical field
The utility model is related to a kind of universal joint, more particularly, to a kind of universal joint with auto-locking suspension oil sealing.
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 lubricating oil of this Hooke's joint is easy to be from oil tight skeleton and outer
Spilt in circle, sealing property is poor, and oil sealing can not bear larger needle roller axial motion power, and oil sealing stress is more easy to fall off, so that
The operation of universal joint is caused relatively to have some setbacks, operating efficiency is relatively low.
Utility model content
The utility model is to provide a kind of universal joint with auto-locking suspension oil sealing, and it is mainly solution prior art and deposited
The lubricating oil of Hooke's joint easily spilt out of oil tight skeleton with outer ring, sealing property is poor, and oil sealing can not be born
Larger needle roller axial motion power, oil sealing stress is more easy to fall off, so as to cause the operation of universal joint relatively to have some setbacks, operating efficiency compared with
Low technical problem.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
A kind of universal joint with auto-locking suspension oil sealing of the present utility model, including cross shaft body, described cross axle
The axis body of body is socketed with outer ring, and double needle roller, the axis body root of cross shaft body and outer ring are provided between outer ring and axis body
Inner oil seal is provided between the inner, inner oil seal includes inner oil seal skeleton, and inner oil seal skeleton contacts outer respectively provided with inner seal liner
Circle and the axis body root of cross shaft body, the end of inner oil seal skeleton is hook-shaped bayonet socket, and the inner surface of outer ring end is provided with peace
Be loaded the neck of mouth, and inner oil seal skeleton is provided with inner seal liner.When oil sealing pours bayonet socket of the outer ring inside on oil sealing can automatic clamping
Enter in neck, oil sealing loads in outer ring rise and block automatically after, effectively prevent in product lubricating oil from oil tight skeleton with going out in outer ring
Existing oil leakage phenomenon.
Preferably, being provided with outer oil seal outside described inner oil seal, outer oil seal includes the outer oil seal bone that section is c-type
Frame, outer oil seal skeleton is provided with outside seal, and the end outer surface of outer ring is provided with oil card groove, and outside seal end is embedded in oil card
Inside groove, another end in contact bayonet socket of outside seal.Interior outer oil seal can bear larger needle roller axial motion power, prevent oil sealing by
Power obscission.
Preferably, the inner bottom part of described outer ring is provided with the oil storage tank of circular arc, the inner bottom surface of oil storage tank insertion outer ring
Edge and outer ring medial surface bottom.Oil storage tank can be with indwelling lubricating oil, and oil storage tank is located at the bottom surface inside outer ring
With side, lubricant effect is preferable.
Preferably, being provided with needle roller back-up ring between described inner oil seal and needle roller.When axial motion occurs for needle roller, needle roller
Back-up ring will play the axial motion power of reduction needle roller, it is ensured that the service life of product.
Therefore, the utility model sets bayonet socket at the metallic framework of oil sealing, when oil sealing is poured in outer ring on oil sealing
Bayonet socket can be caught in the neck of outer ring automatically, and oil sealing, which loads in axle sleeve, to be risen after automatic block, and effectively prevents lubricating oil in universal joint
From oil tight skeleton with being spilt in outer ring, sealing property is higher, and the operation of universal joint is more smooth, and operating efficiency is higher, structure letter
It is single, reasonable.
