Gear differential flank modification design method for low noise
Yu Zhang, Chengyu Duan, Zhiyong Wang, Hong Luo
Izvirni znanstveni članek
Oznake: tooth modification;low noise;angular acceleration;meshing force;
To address the limitations of existing gear tooth modification methods, a differentiated tooth modification method is proposed, where the modification amount of adjacent teeth varies according to a sine function. Initially, a mathematical model of the gear tooth profile varying according to a sine f ...
