机械零部件间的联接方式，主要依靠螺栓进行联接。但在处于高速运转，剧烈振动，环境恶劣工况条件下，目前所广泛采用的标准螺栓联接方式因受到交变载荷的作用，极易产生松动，导致联接失效，轻者降低机械使用寿命，严重时将使机械零部件报废，甚至危及人身安全，造成巨大的经 Mechanical components between the connection, mainly rely on bolts for connection. However, under the conditions of high-speed operation, severe vibration and harsh environment conditions, the standard bolting method currently widely used is prone to loosening due to the alternating load, resulting in the failure of the connection. The lighter will reduce the service life of the machine and cause serious problems When the mechanical parts will be scrapped, and even endanger personal safety, resulting in a huge experience
