Abstract

The invention provides a besides-star wheel which comprises a wheel handle and a wheel head. A plurality of axially extending ball grooves for containing steel balls are arranged on the inner circular surface of the wheel head, a plurality of axially extending trenches are arranged on the outer circumferential surface of the wheel head, and the trenches and the ball grooves are distributed at intervals. Therefore, the thickness of the wheel head can be equalized, the besides-star wheel cannot abnormally deform in the induction quenching process, the ball grooves do not easily crack, and the shape and position accuracy of the ball grooves is improved by an order.

Description

technical field [0001] The invention relates to the field of universal joint manufacture, in particular to a lightweight outer star wheel. Background technique [0002] The driving mode of the car is mainly front-wheel drive, and the front wheel is both a driving wheel and a steering wheel. At present, the drive shaft wheel end of the front wheel mainly adopts a fixed universal joint for transmission connection. The fixed universal joint includes an outer star wheel, an inner star wheel, steel balls and a cage. The steel ball is placed on the window of the cage. The outer star wheel includes a wheel handle and a wheel head. The fairway of the ball, between the two fairways is a spherical surface matched with the cage, the inner star wheel is placed in the cage and cooperates with each other, the outer wall of the inner star wheel is provided with a fairway for accommodating steel balls, and the space between the two fairways is matched with the cage sphere. [0003] There ...
