在机械修理中，常对一些较大的机械零件的圆柱面磨损后采取镶套工艺修复。镶套修复工艺的基本原理就是采用过盈联接的固持力，把镶套用的套筒与零件母体联接起来，修补磨损尺寸达到原来零件功能。该修复工艺关键是选择合理的联接配合，既要使镶套联接具有足够的固持力，以保证 In mechanical repair, often on some of the larger cylindrical parts of mechanical wear to wear after the set of repair process. The basic principle of the set repair process is to use the holding force of the interference connection, the set sleeve with the parts matrix connected to repair the worn parts size to achieve the original function. The key to the repair process is to choose a reasonable connection and cooperation, it is necessary to make the set connection has sufficient retention force to ensure
