New hobbing fixture for machining automotive parts
Usually encountered in the inner spline hole, inner hole and other disc parts, often using cylindrical mandrel positioning, end face compression method to make teeth. This method is restricted by the clearance between the hole and the shaft. After the tooth is made, the radial runout error F_r of the ring gear is detected, which is proportional to the size of the fit gap. With a small clearance, it is difficult to load and unload the workpiece on the mandrel, and the centering shaft wears.
