Backlash Analysis of Compound Planetary Gear Set in Rotary Actuators

[摘要] This paper proposes a model for backlash analysis of compound planetary gear set in rotary actuators. Three main types of errors in the compound planetary gear set are analysed, that is, manufacturing errors, assembly errors and deformation errors. Due to the randomness of the errors, the backlash model of the gear set was established based on probability theory to improve the backlash estimation for the practical applications. Finally, the backlash of a compound planetary gear set was calculated and the influences of main errors to the backlash were also investigated.
