摘要

在电梯中，偏转滑轮和钢丝绳之间的摩擦系数（CoF）对钢丝绳的使用寿命有很大影响。虽然表面粗糙度是影响金属滑轮-钢丝绳 CoF 的关键因素，但其对聚合物滑轮的影响尚不清楚。本研究分析了粗糙度和工作条件对浇铸聚酰胺 6（PA6G）偏转滑轮-热塑性聚氨酯（TPU）涂层钢丝绳接触的影响。统计分析显示，表面粗糙度对低负荷试验的 CoF 有显著影响。本研究大大有助于偏转滑轮加工中的参数选择，以最大限度地减少滑轮和钢丝绳之间的摩擦。

Impact of surface roughness on the coefficient of friction of polymer-on-polymer contacts for deflection pulley-rope systems in the lift industry

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.
