Abstract


In this paper, based on the reference to domestic and foreign ceramic bearings literature , the use of the Hertz space contact theory , design theory and steel bearings , hybrid ceramic bearings with high-speed electric spindle B7007CY of the models in the axial load contact ellipse size, maximum contact stress and the maximum amount of contact deformation changes in computer simulation ; Jones statics design analysis method as the theoretical basis , using the outer ring raceway control theory , considering the influence of the centrifugal force and gyroscopic moment , different speed hybrid ceramic bearings under the conditions of the inner and outer rings in the process of axial load axial elastic approach amount of rolling element and the outer ring raceway contact stress changes in the computer simulation ; equipped with two products hybrid ceramic ball bearings and steel bearings , high-speed electric spindle running test , rolling body temperature rise under different speed conditions the value of electric spindle vibration testing and analysis . The test and simulation results show that the hybrid ceramic bearings is a performance of high-speed spindle bearings , especially in the high-speed light-load conditions .
