Abstract：

For the sliding bearing of 1600 kN servo crank press, its stress state in working was analyzed by numerical simulation, and verified by 10 kN minitype crank press with Fujifilm prescale film. The results show that the stress distributes mainly under the area directly, and the stress gradually decreases from the middle to the ends with uniform distribution. However, the distribution regulation of the contact pressure and the friction shear stress between the bearing and the shaft is similar to the equivalent stress. Thus, bearing thickness increase can reduce the bearing stress and effectively improve the load bearing capacity. Furthermore, a large fit clearance between the bearing and the shaft will result in reducing bearing area of the bearing and increasing the bearing stress. While, the interference fit between the bearing and bearing can make the bearing area of the bearing increase obviously, so the maximum equivalent stress decreases, and the stress distribution is more uniform.
