Abstract:
The article reviews theoretical and practical aspects of the analysis of friction in rotating pairs. The conceptual framework for the study of friction is considered using the example of a friction pin in a bearing. A practical experiment involves calculating the efficiency of cardan transmission through the work expended on the resistance of friction forces in the kinematic pairs of cardan joints. Mathematical dependences determine the elementary work of the friction forces in the kinematic pairs of a single universal joint, the efficiency of the articulated mechanism and the translational kinematic pair in the splined joint of the universal joint.
