摘要
螺纹紧固件在汽车上的应用极为广泛,螺纹联接的可靠性主要取决于螺栓的轴向预紧力,而且螺纹副之间的摩擦系数对装配扭矩的大小也起到关键的作用,在螺纹联接中,影响紧固件摩擦系数的因素比较多。主要从垫片硬度、润滑条件、装配工艺、配合螺母的表面处理方式4个方面分析对紧固件摩擦系数的影响。
Threaded fasteners are widely used in automobiles.Screw connection reliability depends on the axial bolt preload.Friction coefficient between vice thread plays a key role in the size of the assembly torque.There are many factors that affect the friction coefficient of fasteners.This paper analyzes the impact of the fastener friction coefficient from four aspects,mainly including gasket hardness,lubrication,assembly process and the treatments of nut surface.
