To predict the service life of clutch sleeve, major reasons for the change of clearance between the clutch sleeve and shell in service period are analysed. A mathematical model of the clearance is established considering abrasion of the step outside sleeve caused by friction. To determine the size of abrasion, a micro‐convex body model for the friction surface is built. Based on surface fatigue abrasion theory, an abrasion model is established. A life model is established based on the entire abrasion of the sleeve. Fatigue life of sleeve is predicted using the model based on actual surface morphology parameters of the enterprise products. Major factors affecting the abrasion speed are discussed and determined after the prediction result is analysed.

基于磨损数学模型的离合器套筒疲劳寿命预测

为了预测离合器衬套的使用寿命,分析了在使用期间离合器衬套与外壳之间的间隙变化的主要原因。建立间隙的数学模型,其中要考虑到由于摩擦引起的台阶外套筒的磨损。为了确定磨损的大小,建立了摩擦表面的微凸体模型。基于表面疲劳磨损理论,建立了磨损模型。基于套筒的整体磨损建立寿命模型。使用该模型基于企业产品的实际表面形态参数预测套筒的疲劳寿命。分析预测结果后,讨论并确定影响磨损速度的主要因素。
