The coefficient of friction(CoF)between the deflection pulley and rope in a lift strongly affects the life span of the rope.Although surface roughness is a key factor affecting the metallic pulley-rope CoF,its effect on polymeric pulleys is unknown.The present study analyses the effect of roughness and working conditions on cast polyamide 6(PA6G)deflection pulley-thermoplastic polyurethane(TPU)-coated rope contacts.The statistical analysis revealed that the effect of surface roughness on the CoF for low-load tests was significant.The present study contributes significantly to parameter selection in deflection pulley machining to minimise friction between the pulley and rope.
