摘要

This paper proposes a practical manufacturing method for parallel-axis helical gears with a pre-designed transmission error (TE) and localized hearing contact. The tooth contact analysis (TCA) method is applied to investigate the proposed helical gear pair which is composed of an involute pinion and a modified circular-arc gear. The TCA simulation programs investigated the influences of the assembly errors and design parameters of the gear on the TEs and contact patterns of this gear pair. The TE is continuous without any jump and the hearing contact is localized in the middle of the tooth surfaces eventhough the gear pair may have assembly errors. Furthermore, the optimization technique was employed to find the adequate gear design parameters to provide the gear pair with a prescribed TE. Several numerical examples are presented to demonstrate the characteristics of the proposed modified helical gear pair.
