Abstract:Based on the principle of the planetary transmission mechanism, we design a friction drive planetary roller-type precision linear actuator. Using the kinematic analysis, a displacement function of the linear actuator and a cutter path equation for thrust bush manufacturing are obtained. Deformations of the thrust bush under several load conditions are analyzed using the finite element method. Experiments aiming to verify the characteristics of the actuator are carried out, and the results show that the output … Show more
