Abstract:
In full view of the elastie deformation of rubber of water-lubricated rubber bearings and the geomet-.ric construction with multi-curve and multi-vertical grooves , the author employs finite element analysis software“ ANSYS CFX" to do numerical simulation of three dimensional EHL for water-lubricated rubber bearings withgrooves, researching the variation of water film pressure distribution, waterfilm thickness distribution, carryingcapacity and frictional factor under different eceentricity and totate speeds, The results show that the elasticdeformation of rubber and the geometrie construction with multi-curve and multi-vertical grooves can have signifcant influence on the lubricating property of the bearing.
