1.前言 汽车离合器摩擦片由石棉绳、金属丝、玻璃纤维、橡胶、酚醛树脂、填加剂热模压而成,其中石棉绳、金属丝、玻璃纤维主要作用是提高摩擦片成品的机械强度、耐磨性。工艺流程:热模压成圆环—热处理—磨削平面及内外圆加工铆钉孔和铆钉让位孔—成品。这种工艺过程存在以下缺点: (1)经模压而成的圆环摩擦片,石棉绳、金属丝、玻璃纤缡、橡胶均匀地分布在摩擦片中,其机械强度好,抗高速性能强,摩擦系数大且稳定,但因铆接需要,圆环摩擦片上必须加工出铆钉孔及铆钉让位孔。通常加工
1. Foreword Automobile clutch friction plate is made of asbestos rope, metal wire, fiberglass, rubber, phenolic resin and filler. The main function of asbestos rope, metal wire and glass fiber is to improve the mechanical strength of the finished friction lining, Wear resistance. Process: hot-molded into rings - heat treatment - grinding plane and internal and external round rivet holes and rivets to make way for the hole - the finished product. This process has the following shortcomings: (1) The molded ring friction plates, asbestos rope, wire, glass fiber, rubber evenly distributed in the friction plate, the mechanical strength, high speed performance, The coefficient of friction is large and stable, but due to riveting needs, rivet holes and rivets relief holes must be machined on the annular friction plates. Usually processed
