A Comparative Approach Regarding the Dynamic Behaviour of Planetary Transmissions Used in Industrial Robots

2016 
The dynamic characteristics of planetary transmissions have a direct influence over the possibilities of industrial robots regarding the imposed trajectory. Also, the conditions specific to the achievement of the transient regime have a significant influence over the positioning accuracy of the robots. In this paper, a comparative approach is proposed, applied to four types of planetary transmissions, concerning the gyration torque distribution and computation. Based on the computation equations presented in this paper, some optimization strategies concerning the response times of the overall kinematic chains are proposed.
