关于高强螺栓的拧紧、拆卸、抗咬合？ “the nut factor k is an experimental constant, a bugger factor , if you will, which defines the relationship which exists between applied torque and achieved preload in a given situation. the only way to determine what k should be in your application is to make some actual experiments in which you measure both torque and preload and compute the mean k and the scatter in k. if accuracy is not a big concern or you are merely trying to…determine the approximate preloads you will achieve, then it is safe to use a nut factor 上面这段话出自国外机械设计手册 在大批量应用中，k是一个实验系数，对于特定的螺栓和润滑剂，k通过实验方法确定。查看更多
