Technical Field

The invention relates to the technical field of abrasive flow processing, in particular to precise polishing equipment for clutch abrasive flow.

Background

The clutch is used for connecting the shaft and the shaft to achieve movement and torque, and can separate or connect the transmission system at any time during the operation of the machine. The clutch is mainly applied to the operations of starting, stopping, reversing, speed changing and the like of a mechanical transmission system. The jaw clutch utilizes the mutual embedding or separation of teeth on the end faces of the two half clutches to achieve the clutch of a driving shaft and a driven shaft, and the teeth have several forms such as rectangle, trapezoid, triangle, sawtooth, spiral and the like. Because the number of teeth participating in embedding is large, the bearing is high, and the application range is wide.
