Analysis of Harmonic Gear Drive Efficiency Based on the 3D Simplified Model

Abstract:

This study based on the finite element method, the type of XB1-120-100 harmonic drive output torque and input rotational speed impact on transmission efficiency has been analyzed. The results show that the efficiency of harmonic gear drive increases with the output torque increased, and it has no relation with input rotational speed. When the output shaft takes the value of rated torque (T_out=450Nm), the transmission efficiency of harmonic gear drive obtained by the finite element numerical simulation is 87.1%. This value of transmission efficiency is quite close to the type of XB1-120-100 harmonic drive efficiency (75%-90%). The above analysis method and results have a guiding significance for the transmission design and performance analysis of harmonic gear drive.
