Abstract
The utility model relates to a universal joint cross shaft with a shaft neck with a conicity structure, which is characterized in that the position of the shaft neck of the cross shaft in contact with a rolling needle bus is provided with a certain conicity. The structure of the utility model can effectively improve the singular distribution phenomenon of contact loads between the rolling needle bearing and the shaft neck of the cross shaft to make the loads in the contact area of the rolling needle bearing and the cross shaft distributed as uniform as possible so as to greatly prolong the service life of the universal joint cross shaft assembly.
Description
Technical field
The utility model belongs to the technical field that auto parts and components are made, the particularly universal-joint cross trunnion of axle journal band tapered configuration.
Background technique
At present, in the universal-joint cross trunnion assembly structure, because assembly structure deformation reason under radial clearance between trunnion journal and the needle bearing and the loading, make that the load distribution of needle bearing assembly and cross axle contact area is extremely inhomogeneous, in double needle bearing structure, big load is born in the needle bearing outer end, and the most of contact area of interior row's needle roller bearing load hardly, easy like this causing effluxes the end of needle roller and cross axle contact area bearing big load and takes place to roll distortion in early days and lost efficacy, and has a strong impact on universal-joint cross trunnion assembly working life.Abroad, Bearing Factory's technology is more advanced, and general the employing improved the needle roller shape, adopts the needle roller design of optimizing the convexity structure, and then makes needle bearing and cross axle contact area load be evenly distributed as far as possible, improves universal-joint cross trunnion assembly working life.
Summary of the invention
The utility model purpose provides a kind of universal-joint cross trunnion of axle journal band tapered configuration.
The technical solution of the utility model is achieved in that
The universal-joint cross trunnion of axle journal band tapered configuration is characterized by: have certain tapering at trunnion journal and needle roller bus contact position.
The utility model structure can effectively be improved the unusual distribution phenomenon of contact load between needle bearing and the trunnion journal, makes needle bearing and cross axle contact area load be evenly distributed as far as possible, and then significantly improves the universal-joint cross trunnion assembly life-span.
Description of drawings
Fig. 1 is original universal-joint cross trunnion structural representation.
Fig. 2 is the utility model structural representation.
Embodiment
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
The universal-joint cross trunnion of axle journal band tapered configuration is characterized by: contact the L position at trunnion journal with the needle roller bus and have certain tapering 1.
Embodiment:
Comparison diagram 1 and Fig. 2, one vapour Φ, 62 universal-joint cross trunnion products have been carried out band cone angle structural design, universal-joint cross trunnion axle journal and L position, needle bearing contact area are designed to tapering 1 structure, and carried out contact stress optimization and analyzed, calculate the amount of deformation of contact area axle journal according to the size of cross axle load rating, carry out the tapering size design by amount of deformation, avoid effluxing needle roller and contact in advance and cause early damage.From universal-joint cross trunnion assembly contact simulation result, as can be seen, organization plan of the present utility model can effectively improve the load concentration distribution problem, and then significantly improves the universal-joint cross trunnion assembly life-span.
Claims (1)
1. the universal-joint cross trunnion of axle journal band tapered configuration is characterized by: contact the L position with the needle roller bus at trunnion journal and have certain tapering (1).
