| Abstract: | A basic model of hybrid bearing lubrication mechanism is established based on Reynolds equation and flow continuity equation and those equations are solved by using finite difference method. Solving methods are given for calculating load -carrying capacity, temperature rise and friction power consumption of a hybrid bearing, which provides a theoretical basis for hybrid bearing design calculation and analysis and a guidance for engineering design and calculation. |
