Summary

To investigate the influences of friction of the vane sliding surface between the vane and vane slot on the lubricating conditions between the vane top and the rolling piston, we perform a numerical analysis of rolling piston and vane motion, considering mixed lubrication of the vane sliding surface between the vane and vane slot. Analysis results indicate that the risk of scuffing is high between the vane top and piston due to increased PV value near crank angle ? = 180°, at which the lubrication is poor when the contact friction forces of the vane sliding surface increase. Moreover, the vane separated from the piston may collide with the piston at crank angle ? = 180°, and excessive impact may occur between the vane top and the piston due to increased contact friction forces of the vane sliding surface.
