On the torque transmission by a Cardan-Hooke joint
In literature regarding the dynamics of the CardanHooke joint, the inertial characteristics of shafts and a cross and their influence on the joint torque transmission are often ignored (see e.g. [1]). In [2], the cross inertia and its effect on shafts bearing reactions at the constant angular velocity of the input shaft was considered. On the other hand, the problem of the torque transmission at a variable angular velocity of the input shaft and in the presence of both structural and error misalignments between the shafts is considered in [3]. Moreover, the inertial characteristic of the cross is not taken into account. In [4], only the inertia of shafts was taken into account. The aim of this paper is to form a relation between the applied and resisting torques, which will be taken into account inertial characteristics of both the cross and the shafts. In general case, the variable angular velocity of the input shaft is assumed where elasticity effects and friction are ignored.
