Abstract
The vari-speed drive, which transmits motion and torque through planetary gear and centrifugal rotor, plays an important role in mechanical transmission system. It is mainly used in ships, rolling mills, automobiles and other fields. The vari-speed drive can improve the dynamic performance and economy of the vehicle through the continuous change of transmission ratio. In this paper, an innovative planetary centrifugal vari-speed drive is presented. The structure and working principle of the device are introduced. The multi-body dynamics modeling of the vari-speed drive is established to obtain the working characteristics and vibration characteristics of the mechanism under different working conditions. A compression spring is installed between the centrifugal rotors, and the influence of spring on the system performance is analyzed. This paper can provide a theoretical basis for the design of planetary stepless transmission.
