Oil Film Properties of Three Oil Wedge Sliding Bearing and its Effect to the Rotor Stability

Abstract:

Calculating navier-stokes equation to study oil film pressure characteristics of three oil wedge bearing by using CFD software. Studied how to the three oil wedge sliding bearing effect on rotor stability, and analyzing oil film pressure characteristics of three oil wedge sliding bearing and cylindrical bearing. The results showed that three oil wedge bearing is much more stable than the cylindrical bearing, it is more advantageous to the running rotor and unit at stable working than the cylindrical bearing in the same oil film thickness and inlet pressure.
