摘要

Aimed at misalignment caused by shaft deformation under centrifugal inertial load for eccentric rotor-bearing Friction pair, hyperboloidal sliding bearing that have correct centering was designed. According to the lubrication theory and the reliability design theory, optimum design with numerical algorithm of hyperboloidal sliding bearing based on the reliability constraints were put forward. Different from ordinary optimization of sliding bearing based on empirical correlation, the multi-objective mathematical model of sliding bearings based on the reliability constraints was established and solved by numerical algorithm. Global optimum design plan of the sliding bearing's parameter were obtained, under meeting carrying capacity and strength conditions of the sliding bearing, the friction power and temperature rise of the sliding bearing were minimal, volume of the sliding bearing was decreased.
