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 cooperation of the oil seal lip and cross axle of this Hooke's joint compared with
To be loose, prevent that lubricant grease of the universal joint operationally in outer ring is easily outer stagnant, sealing property is poor, so as to cause universal joint
Operation relatively have some setbacks, operating efficiency is relatively low.
Utility model content
The utility model is to provide a kind of two-directional composite sealing universal joint, and it is mainly present in solution prior art
The cooperation of the oil seal lip and cross axle of Hooke's joint is more loose, prevents lubricating oil of the universal joint operationally in outer ring
Fat is easily outer stagnant, and sealing property is poor, so as to cause the operation of universal joint relatively to have some setbacks, the more low technology of operating efficiency is asked
Topic.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
A kind of two-directional composite sealing universal joint of the present utility model, including cross shaft body, described cross shaft body
Axis body be socketed with outer ring, double needle roller is provided between outer ring and axis body, the middle part of cross shaft body is provided with oil nozzle, cross axle
Outer oil seal and inner oil seal are provided between the axis body root of body and outer ring are inner, the end outer surface of outer ring is provided with oil card groove, outside
Oil sealing is embedded in inside oil card groove.Upper bore exterior design in outer ring has oil card groove, so ensure that the installation of oil sealing, prevents
Only it comes off when in use.
Preferably, described outer oil seal includes the outer metalwork that section is c-type, outer metalwork is provided with external seal
Part, inner oil seal includes the interior metalwork that section is S types, and interior metalwork is provided with inner seal liner, and inner seal liner is sealed in outer ring
Between the axis body root of cross shaft body, spring is embedded with inner seal liner.Spring is designed with inner oil seal, spring is being used
During always inwardly remain certain and tighten power, it is ensured that oil seal lip is always fitted close with cross shaft body, is prevented
It is only stagnant outside lubricant grease in universal joint.
Preferably, described outside seal has three sealing lips, two of which sealing lip is fitted close with outer ring, separately
One sealing lip is contacted with the lip of inner seal liner.Outer oil seal is designed as three lips, wherein two lip universal joint outer rings are close
Coordinate, prevent the muddy water and dust of outside from entering in outer ring, the 3rd lip is contacted with inner oil seal lip, and power two is tightened by spring
Contacted when oil sealing is always closed.
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.
Preferably, being provided with pad, the middle part of pad between the described end face of cross shaft body and the inner bottom surface of outer ring
Thickness is more than its edge thickness.Pad can prevent cross axle from wearing and tearing, and high outer low in pad, be easily installed needle roller.
Therefore, the utility model oil sealing two-way by setting so that sealing is more efficient, prevents stagnant outside lubricant grease,
The operation of universal joint is more smooth, and operating efficiency is higher, simple and reasonable for structure.
