矿山大型机电设备有许多是靠过盈配合联接或以无键联接来传递扭矩的情况。由于矿山大型机电设备自身的特点,其过盈量往往取得很大,通常做成不可拆卸的联接,在检修时不得不加以破坏。在没有原有设备任何有关资料的前提下,如何确定过盈量的大小和工艺结构将直接影响到检修工程的 Many of the mine’s large electromechanical devices transmit torque through interference fit or keyless coupling. Due to the characteristics of large-scale mine mechanical and electrical equipment, the interference is often made large, usually made of non-removable joints, had to be destroyed in the repair. In the absence of any relevant information on the premise of the original equipment, how to determine the size of interference and the structure will directly affect the maintenance of the project
