扭轮摩擦传动机构动力学分析

Dynamics analysis of twist-roller mechanism

从四种工作状况出发对扭轮摩擦传动机构进行了动力学分析,讨论了扭轮平移加速度和驱动力矩及扭轮承受载荷的关系、扭轮纯滚动的动力学条件以及驱动力合力和扭轮轴线的夹角.通过分析表明,载荷对扭轮平移加速度和传动轴圆周切向驱动力的影响很小.

On the basis of four different kinds of working condition, the twist\|roller frictional transmission mechanism was analyzed from the point of dynamics, and from the analysis, the relationship between the acceleration of the twist\|roller and the driving torque of the transmission shaft and that between the acceleration and the axial load, the kinetic limitation for pure rolling of the roller, and the function of the angle between the resultant driving force that was put on the twist\|roller and the axis of the roller were obtained. Results show that the acceleration and the circumferential tangent driving force of the twist\|roller almost have no relation with the axial load.
