UPPER BOUND TO MECHANICAL POWER TRANSMISSION LOSSES IN WIRE ROPE
A study is reported in which the mechanical power loss due to friction between wires of a strand bent over a sheave was determined by considering the components of curvature and twist of a helical wire treated as a frictionless helical spring. It was found that the power loss, although small, is reduced by selecting a strand in which the outer wires contact the center wire and by reducing the diameter of the outer wires relative to the center wire. It is noted that in multi-layered wire ropes, these results indicate that contact should occur between adjacent layers but not between wires or strands in a layer.
