Abstract

Tribological studies conducted wear of the friction pair «cable block – rope», including rolling with sliding. It was found that wear does not depend on the hardness of the contacting surfaces at least by 5% slip. With the reduction of the surface roughness the coefficient of friction for the surfaces with grease decreases. It is shown that the slippage of up to 2%, a sharp change in the coefficient of friction, after which it remains almost flat due to the spread of slip on the entire contact area. Bearing strain increases with increasing slip, if the shear stresses are sufficiently large
