| Abstract: | This paper Introduces the cause that the foundation bolt connection is invalid on the pillow block bearing of transmission gear for CFH- II type wagon Tipper. Educes a conclusion that controling and ensuring pre-stress of foundation bolt force is sticking point prevented connection invalidation. According to field condition presents a pre-stress assemblage technics of heatting . It is credible and simple assemblage technic by trying |
