Description
technical field [0001] The invention relates to a grinding jig for a tapered hole of a gear ring of a synchronizer. Background technique [0002] Synchronizers are key components of automotive manual mechanical transmissions. The synchronizer ring is a key part of the synchronizer, which plays a key role in the gear shifting process of the car. During the shifting process, the torque and motion are transmitted by the friction generated by the contact between the inner tapered surface of the synchronizer ring and the conical hub to be joined. Therefore, the performance of the synchronizer ring is related to the reliability of the car's gear shifting. The processing technology and machining accuracy of the inner tapered surface of the synchronizer ring determine the performance of the synchronizer ring. The current grinding process of the synchronizer gear ring is as follows: use a hydraulic three-jaw chuck to clamp the outer circle on the CNC internal grinding machine, grin...
