Abstract

Taking the three-tooth difference swing-rod movable teeth transmission system as the research object, the equivalent error model of the three-tooth difference swing-rod movable tooth transmission system is established considering the main component error and meshing stiffness factors. And the dynamics equation of the system is established based on Newton's second law. By comparing the vibration response of separator considering all errors with that considering only critical errors, it is proved that the critical error is the main factor affecting the vibration response of the separator. Then, ADAMS is used for vibration simulation to verify the theoretical analysis results. Two groups of wave generators and ring gears with different accuracy are processed, and the vibration response of separator is tested. The results show that the dynamic characteristics of the transmission can be improved effectively by controlling the critical errors. This study can provide a theoretical basis for the rational allocation of machining errors of the three-tooth difference swing-rod movable teeth transmission system.
