KED ANALYSIS FOR
THE IMPULSE
VARIABLE SPEED DEVICE AND ITS
REAL MOTION LAW*
Abstract: A comprehensive dynamic analysis is performed for the impulse variable speed device. On the one hand, the system is simplified an equivalent dynamic model considering the friction in pairs and the speed of electromotor. On the other hand, the dynamic model of wedge process is constructed for the roller clutch involving the elastic contact and the rolling friction. Finally, the kineto-elastodynamic (KED) analysis is carried out for this mechanism in consideration of all the factors mentioned above. Then the characteristic kinematic
and dynamic, the constrained forces in pairs and the dynamic
process of the roller clutch are educed considering the vibration. A basis for the development and dynamic design of the variable speed device are provided.
