Abstract

Abstract: The effect of the misalignment can be alleviated effectively by applying proper lead crown relief so that the contact state and the transmission stability can be improved. An analysis model considering gear tooth modification and misalignment is established based on the theory of loaded tooth contact analysis， and the validity of the model is verified by ANSYS. The time-varying mesh stiffness and contact stress of the gear pair under different contact states are analyzed. Finally， with reducing the contact stress of the tooth surface as the optimization objective， the quantity of the lead crown relief of the gear pair is optimized. The calculation efficiency is greatly improved under the premise of ensuring the calculation accuracy. The study provides a theoretical basis for the optimization of tooth modification for gears with misalignment.

Key words: misalignment, tooth modification, mesh stiffness, contact stress, modification optimization
