Abstract
The utility model mainly solves the technical problems that the friction between the end surface of a trunnion and a bearing seat is easily increased, a slide is easily generated, movement is not stable, resistance is large, etc., because a gap between the trunnion head of the trunnion and an oil seal is larger. The utility model comprises the trunnion and a wing-shaped bearing seat which is arranged in the trunnion head of the trunnion, wherein, the basal part of the trunnion head of the trunnion is provided with a dust cover; an abrasion-proof spacer with an oil storage slot and a central hole is arranged between the trunnion head of the trunnion and the inner threshold of the wing-shaped bearing seat. Because the utility model is additionally provided with the abrasion-proof spacer, in the process of operation, because the oil storage slot can store lubricating oil, wearing resistance and dynamic balance cushion performance are more enhanced. In addition, because the abrasion-proof spacer has certain elasticity, assembling error is compensated, and the axial slides of the end part of the trunnion are reduced.
Description
Technical field
The utility model relates to a kind of wing Hooke's joint, especially relates to a kind of wing Hooke's joint with pad.
Background technique
The bottom of the bearing support of existing wing Hooke's joint is directly with the end of cross axle and contacts, owing to there is machining error, exist between cross axle and the bearing support gap, the contact inhomogeneous, can cause the friction between cross axle and the bearing support, resistance to motion is big.The model utility (number of patent application is 00206624.6) that the claimant once applied for " the wing universal joint of interior retaining location " by name.It mainly is to be pruned in the front portion of the key of wing bearing support, and its end face is provided with the key mating face; Be provided with the mating face that matches with the key mating face in transmission fork locating face inboard.Therefore, have rational in infrastructurely, easy to process, reduce the radius of clean-up of working surface and mating face, be beneficial to the raising of Location accuracy, and can improve work efficiency greatly, improve and cooperate and characteristics such as anti-shear performance is good.But the phenomenon of cross axle head axial float, bumpy motion still exists.
Summary of the invention
The utility model mainly is that the gap is bigger between existing existing cross axle spindle nose of wing Hooke's joint of solution and oil sealing, easily increases the friction between cross axis faces and the bearing support, and produces play, bumpy motion, the technical problem of the big grade of resistance.
The utility model mainly solves the problems of the technologies described above by following technical proposals: it comprises cross axle and is located at the interior wing bearing support of its spindle nose, base portion at cross-axis head is provided with dust-proof cover, it is characterized in that being provided with the wear-resistant gasket of being with oil storage tank and center hole at cross axle spindle nose and wing bearing support home record interdigit.Like this, because there is certain elasticity in wear plate, remedied assembly error, increased its wear resistance and balance quality, motion is steady, and frictional force is little, has prolonged the working life of universal joint.
As preferably, the center hole of described wear-resistant gasket matches with the diameter of axle of cross axle, and is provided with the radial oil storage tank of 6-10 bar in the one side.
As preferably, described wear-resistant gasket according to different structural requirements, also can be equipped with described oil storage tank in its both sides.
As preferably, the oil storage tank on the described wear-resistant gasket is the cell bodies of some the arcuations of evenly arranging.
As preferably, be provided with the needle roller back-up ring in the outer rim of described wear-resistant gasket.
As preferably, adopt interference fit between described wing bearing support and the cross axle spindle nose, described wear-resistant gasket compression is gone up it at interval, and its magnitude of interference is 0.03-0.25mm.
As preferably, described wear-resistant gasket can adopt glass-reinforced nylon, molybdenum disulfide-filled composite material, metal, metallic composite to make.
Therefore, the utlity model has good wear resistance, certain dynamic balancing shock-absorbing capacity, structure is more reasonable.

Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: the wing gimbal structure of home record band pad is: be provided with needle roller 3 around cross axle 1 spindle nose, cross axle 1 is arranged on the wing bearing support 2, seal with oil sealing 4 between cross axle 1 and the wing bearing support 2, and dust-proof cover 5, cross axle 1 spindle nose and wing bearing support 2 home record interdigits are provided with wear-resistant gasket 6 (referring to accompanying drawing 1).
A kind of wear-resistant gasket 6 can be to be provided with equally distributed 8 radial oil storage tanks 7, and oil storage tank 7 communicates with wear-resistant gasket 6 center holes 9, and center hole 9 communicates with oilhole on the cross axle 1 (referring to accompanying drawing 2).The utility model has increased described wear-resistant gasket 6, in operation process, because oil storage tank 7 can be stored lubricant oil, abrasion resistance and dynamic balancing shock-absorbing capacity have more been increased, efficiently solve existing technical barrier, thereby the bulk life time of universal joint is greatly improved, realized the aforesaid goal of the invention of the utility model well.In addition,, remedied assembly error, reduced the axial float of cross axle 1 end because wear-resistant gasket 6 has certain elasticity.
Embodiment 2, and a kind of wear-resistant gasket 6 can be to be provided with equally distributed 10 arc oil storage tanks 7, and wear-resistant gasket 6 edges are provided with bulge loop 8 (referring to accompanying drawing 4).Owing to be provided with bulge loop 8, in operation process, the lubricant oil that can stop oil storage tank 7 stored is got rid of to be taken off, and more can reduce friction effectively.According to different requirements, needle roller 3 can be assemblied in the bulge loop 8, also can fit flush.All the other reference examples 1.
