Description
Technical field
The utility model relates to a kind of universal joint, is dustproof and good sealing effect, dust-proof cover difficult drop-off and not squashy universal joint of a kind of energy specifically.
Background technique
Existing universal joint generally all is made up of cross axle, bearing and oil nozzle, the dust sealing weak effect, silt etc. is invaded universal joint inside easily in the using process, thereby makes universal joint not have effect, though or dust-proof cover arranged on the cross axle, but when assembling, be easy to come off, and frangible, assembling capacity is poor, and the end face of cross axle directly contacts with the bearing bottom, be easy to wearing and tearing, sintering, life of product is short.The applicant also once applied for the patent of relevant dust-proof sealing structure universal joint, as the universal joint (patent No.: 200420082640.3) with the self-locking dust-proof sealing structure, though the patent of the applicant application has constantly been improved existing shortcoming in the prior art, the aspect also has deficiency to prevent that at dust-proof sealing structure and when assembling dust-proof cover from coming off etc.
As mentioned above, there is following deficiency in prior art: sealing effect relatively poor or when assembling dust-proof cover come off easily, crushing etc., assembling capacity is poor, working life is short.
Summary of the invention
The utility model solved sealing effect that prior art exists relatively poor or when assembling dust-proof cover come off easily, crushing etc., the problem of assembling capacity difference provides a kind of energy dustproof and good sealing effect, dust-proof cover difficult drop-off, not squashy universal joint.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of universal joint of dust-proof sealing structure, comprise cross axle, the dust-proof cover of being located at the oil nozzle of cross axle central authorities and the bearing on the cross axle spindle nose and being arranged at bearing mouth end, be provided with the oil sealing of needle roller and S type skeleton in the described bearing, the bearing periphery is provided with the outer ring, described skeleton S type is translated into the anticreep tying outside the outer end, it is characterized in that described dust-proof cover is an elastomer, and it is embedded with the dust-proof cover skeleton.By cooperating of self-locking dust-proof cover and self-locking outer ring, prevent coming off of dust-proof cover, improved the assembling capacity of product; Dust-proof cover is an elastomer, can be rubber material, and it has rebound elasticity preferably, contacts with cross axle, axle sleeve and oil tight skeleton flexibility, and compensate for wear has good seal action automatically; And the elastomer dust-proof cover of rubber material is embedded with the dust-proof cover skeleton, can solve its easily problem of crushing, working life also corresponding length.
As preferably, the dust-proof cover skeleton is the U-shaped that does not wait on both sides, its the long end and the end, are arranged on the dust-proof cover periphery, short end is excessive in dust-proof cover inside the end of by, dust-proof cover uses two layers of material, iron skeleton and building rubber compound make dust-proof cover skeleton and dust-proof cover combine closely, and have solved the easy crushed problem of dust-proof cover.
As preferably, the outer ring is provided with recess, can so that its can and dust-proof cover on the mousing-hook that is provided with match, have the effect of self-locking, make the dust-proof cover difficult drop-off, the effect of energy enhanced leaktightness.
As preferably, dust-proof cover skeleton and bottom, outer ring and described skeleton S type outer end form cavity body.
As preferably, be provided with the anticreep lip that matches with the anticreep tying in the dust-proof cover, the anticreep lip enters the S shape skeleton place that outwards curves suitable for reading, makes dust-proof cover and S shape skeleton link together like this, forms the better seal effect.
As preferably, be provided with the mousing-hook that the recess that is provided with the outer ring matches in the dust-proof cover, have the effect of self-locking, make the dust-proof cover difficult drop-off, effect that can enhanced leaktightness.
As preferably, anticreep lip that is provided with in the dust-proof cover and anticreep tying interference fit, its magnitude of interference is 0.05～1mm, because skeleton is longer, skeleton is rigid materials such as iron, and its magnitude of interference makes dust-proof cover difficult drop-off and enhanced leaktightness effect by making the anticreep lip be pressed into inboard wall of skeleton after press-fiting.
As preferably, the recess interference fit that mousing-hook that is provided with in the dust-proof cover and outer ring are provided with, it is 0.05～1mm at magnitude of interference radially, this interference fit is that the flexibility by the dust-proof cover rubber material has preferably that rebound elasticity contacts with the outer ring is flexible, automatically compensate for wear has the better seal effect.
As preferably, the outer ring is a U-shaped, and its U-shaped bottom is provided with pad, described pad is provided with oilhole, and described pad adopts nylon material, and this nylon spacer has wear resistance preferably, can avoid cross axle directly to contact and cause premature wear or sintering, thereby prolong the working life of universal joint with the outer ring.
The utility model is skillfully constructed, by combining of self-locking dust-proof cover and self-locking outer ring, prevent coming off of dust-proof cover, dust-proof cover adopts rubber to add iron skeleton, prevents that it is frangible, and because rubber has good rebound elasticity, make its compensate for wear automatically, have good seal action, assembling capacity is good, long service life.
