Description
Technical field
The present invention relates to the fields of universal joint, and in particular to a kind of universal joint of composite construction.
Background technique
Universal joint in the process of running, needs sufficient lubrication, while also to prevent the foreign matters such as external dust, muddy water from invading
Enter inside needle bearing, prevents the abrasion for accelerating the parts such as needle roller.Therefore the needle bearing of universal joint must be provided with reliable close
Envelope, traditional universal joint outside framework oil seal are generally two lips or the isostructural oil sealing of three lips, are matched by oil seal lip to related
It closes position interference fit to be sealed, but oil tight skeleton directly cooperates with outer ring inner circle, can more or less there is some gaps.Specially
Benefit numbers 201010140883.8: universal joint described in a kind of fastened sealing structure of cross universal joint patent document is in operation
There are oil sealings to rotate relative to outer ring, and the problems such as not ideal enough is sealed between oil sealing and outer ring, may be made in bearing outside lubricating grease
It overflows.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of universal joint of composite construction.
The object of the present invention is achieved by the following technical solutions: the universal joint of this composite construction mainly includes
Cross axle, needle roller, outer ring, dust cover, dust cover lip A, dust cover lip B, dust cover lip C, oil tight skeleton, oil sealing, oil
Lip A, oil seal lip B are sealed, outer ring is installed on four axle journals of cross axle, needle roller is installed between outer ring and axle journal and constitutes bearing, outside
Dust cover is set between circle and axle journal and oil sealing is sealed, oil sealing is equipped with oil seal lip A, oil seal lip B, oil seal lip A and oil
The journal engagement for sealing lip B and cross axle seals, and dust cover is equipped with dust cover lip A, dust cover lip B and contacts axle journal platform respectively
Sealing is formed on the inside of the oil tight skeleton of rank and oil sealing, dust cover is additionally provided with round recessed sealing outside dust cover lip C cooperation outer ring.
Oil tight skeleton is set in the oil sealing.
The oil tight skeleton in bending shape and mainly by skeleton oral area turn up A, B, the portion skeleton C are constituted in the middle part of skeleton, bone
Turn up A and outer ring oral area of frame oral area cooperates, and B and outer ring cooperate fixed oil sealing position in the middle part of skeleton, and skeleton C covers rubber layer outside portion
It is interference fitted to form sealing with outer ring inner circle.
The dust cover is made of skeleton and rubber.
There are also outer ring outer port part setting step and dust cover lips for cooperation between the dust cover lip C and outer ring outer circle
The mode of one to three dust-proof lip and the cooperation of outer ring step is arranged in mouth C.
The invention has the benefit that the present invention solves in the prior art, oil seal for universal joint assembly is difficult, there are oil leak wind
The problems such as dangerous, realizing while guaranteeing that easy to assembly, sealing effect is good prevents extraneous muddy water, dust impurity intrusion, and
The effect that the sealing of lubricating grease is not revealed in universal joint, to extend universal joint service life.

Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
Embodiment: as shown in the picture, the universal joint of this composite construction mainly includes cross axle 1, needle roller 2, outer ring 3, prevents
Dust hood 4, dust cover lip A41, dust cover lip B42, dust cover lip C43, oil tight skeleton 5, oil sealing 6, oil seal lip A61,
Oil seal lip B62 installs outer ring 3 on four axle journals of cross axle 1, and needle roller 2 is installed between outer ring 3 and axle journal and constitutes bearing, outer ring 3
Dust cover 4 is set between axle journal and oil sealing 6 is sealed, dust cover 4 is made of skeleton and rubber.Oil sealing 6 is equipped with oil seal lip
The journal engagement of A61, oil seal lip B62, oil seal lip A61 and oil seal lip B62 and cross axle 1 seals, and dust cover 4 is equipped with anti-
Dust hood lip A41, dust cover lip B42 are contacted respectively forms sealing, oil sealing on the inside of the oil tight skeleton 5 of axle journal step and oil sealing 6
Skeleton 5 in bending shape and mainly by skeleton oral area turn up A51, B52, the portion skeleton C 53 are constituted in the middle part of skeleton, skeleton oral area turns up
