Detailed Description
The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, the low-resistance large-swing-angle steel ball type sliding end universal joint comprises a shell 1, wherein a three-ball pin assembly 2 in movable fit is arranged in the shell, a rolling way 10 is arranged in the shell, the three-ball pin assembly consists of a three-pin frame 21, an inner ball ring 22, an outer ball ring 23 and rolling balls 24, a plurality of pin shafts 25 are arranged on the three-pin frame, the inner ball ring 23 is arranged on the outer wall of each pin shaft, the rolling balls 24 in rolling fit are arranged on the outer wall of each inner ball ring, the top ends of the rolling balls are in rolling fit with the rolling way, and through holes for placing the rolling balls are formed in the outer ball; the raceway comprises a first arc surface 101 and a second arc surface 102, and the first arc surface and the second arc surface are tangent to the rolling ball. Compared with the existing tripod type sliding end universal joint, the universal joint cancels the roller pin, and transfers the space of the roller pin to the pin shaft of the tripod, thus increasing the diameter of the pin shaft and the bearing strength between the pin shaft and the hub, leading the tripod assembly to bear higher torque, prolonging the service life of the product, and simultaneously avoiding the problems that the roller pin is crushed and the like.
In this embodiment, as shown in the figure, the curvatures of the first arc surface and the second arc surface are the same.
