The effect of refrigerants on the lubrication of rolling element bearings used in screw compressors.

Author(s) : WARDLE F. P., JACOBSON B., DOLFSMA H., et al.

Summary

The formation of sufficiently thick lubricant films at the highly stressed contacts within a rolling bearing is a prerequisite for reliable operation. These films are a function of the lubricant's physical parameters: viscosity and pressure-viscosity coefficient. In the screw compressor bearing application, either or both parameters may be adversely affected by the presence of refrigerant. Experimental measurements are presented for oil-rich solutions of R22 and a naphthenic oil and of R134a and ester oils.
