A rotor-journal bearing system for a twin rotary compressor has been nlliDerically analyzed to estimate the reliability and to optimize the bearing design. For rotary compressors, large dynamic loads act on the rotor. They are unbalanced forces due to eccentric rotation parts and gas forces induced by the difference in pressure between compression and suction gases. In such a case, the rotor-jo...

With the higher rotational speeds and loads in bearings, gaseous cavitation becomes more cannot be ignorable bearing designs. However, there is no enough research non-equilibrium model. This paper builds a new model based on Bunsen solubility bubble dynamics. The equilibrium pressure calculated by local its difference with decides mass transfer rate this for cavitation. A titling-pad journal at...
