Abstract:In order to study the influence of different slip conditions on the friction of cylindrical pittextured journal bearings,a friction calculation model of cylindrical pittextured journal bearings under different interface slip conditions was established,and the parameters affecting the friction of textured journal bearings were investigated.The law of influence of interface slip on the friction of cylindrical pittextured journal bearings under different slip conditions was analyzed by ANSYS.The results show that the friction force of textured sliding bearings is mainly determined by journal linear velocity,oil film slip ratio,inlet and outlet pressure of bearings,oil film pressure at texture,texture depth,oil film thickness and loadbearing capacity.The friction force of texture model is less than that of nontexture model under different slip conditions.When both upper and lower surfaces slip,the texture of cylindrical pits at the outlet position shows the optimum loadbearing and frictionreducing effect.The friction performance of the model can be improved by properly increasing the depth of the cylindrical pit texture,but too deep pit texture can not exert its performance.
