一、前言螺栓润滑技术主要用于紧螺栓联接.紧螺栓联接的工作特点是在装配时必须根据设计要求,在被联接件承受工作载荷之前,将螺栓或螺母拧紧,使其产生一定值的轴向预紧力.通常,预紧力的大小是靠工人凭经验来控制的.由于各种原因,螺栓所产生的预紧力往往与理论上所需的正确值有很大的出 I. INTRODUCTION Bolt lubrication technology is mainly used for tight bolt connection.The working characteristic of tight bolt connection is that it must be designed according to the design requirements, before being subjected to the working load by the coupling, tighten the bolt or nut to produce a certain value of the shaft Generally, the amount of pretension is controlled empirically by the worker, and for various reasons the preload on the bolt tends to be quite large with the theoretical correct value
