摘要
根据凸轮激波摆动活齿传动的工作原理,在考虑该传动中的摩擦力和摩擦力矩的情况下,探讨凸轮激波器、活齿柱销、内齿圈对活齿的作用力,并借助变形协调关系对作用在活齿上的各力进行求解。提出凸轮激波摆动活齿传动的瞬时啮合效率和平均啮合效率的计算方法,推导相应的效率计算公式,并给出计算实例,计算结果表明该效率计算方法切实可行。
According to the transmission principle of swing movable tooth transmission actuated by cam,the forces exerted on the movable teeth by the cam disk profile,movable teeth spar pegs and the contour of internal gear were studied with the consideration of friction forces and friction torques in the transmission.The calculation formulae of the forces exerted on the movable teeth were derived with the help of the deformation coordination equations of the swing movable tooth transmission actuated by cam.Based on the force analysis,the method used to compute the instantaneous meshing efficiency and the average meshing efficiency of the swing movable tooth transmission actuated by cam were put forward and the corresponding formulas for evaluating the efficiency were derived.A numerical example was given for illustration.The results showed that the efficiency calculation method is practical.
