EXPERIMENTAL EVALUATION OF THE INFLUENCE OF OUT-OF-ROUNDNESS OF ROTATING PAIRS ON FRICTION TORQUE OPERATING UNDER DRY FRICTION CONDITIONS

摘要

The article considers the main factors influencing the magnitude and nature of the change in friction torque in rotating pairs and shows the influence of deviations of the shape of holes on its magnitude. The scheme of laboratory installation used in experiment for measurement of the friction torque is resulted. Statistical estimates of the values of deviations of the shape of ring samples and their influence on the change of friction torque under dry friction conditions are given. The nature and types of wear of the rotating element of the pair are determined.
