Abstract��Service life of copper shoe in open joint of the universal joint spindle used for 2050 HSM RM No.2 is lower, and serious scuffing between roll wobbler and copper shoe is often occurred. The problem above mentioned was detail analyzed in this paper. Shown as metallographic analysis, serious shear plastic deformation had occurred on the friction surface and its depth was more than 1��54 mm. This phenomenon only does occur in very small area, its reason is that friction shear force are more than allowable stress of the material. It is basic method that lubrication condition are changed, friction coefficient are lowed and yield strength and anti��seizure of the material are increased.
