Résumé

For a rolling piston rotary compressor, oil supply into various lubrication elements was analytically studied. The lubrication system, consisting of a centrifugal shaft pump, radial oil feeding holes, bearings with grooves and some other sliding surfaces, was modelled by employing an equivalent electric circuit network. A computer simulation programme was developed to solve the network model of the lubrication system. Its numerical solutions include total oil flow rate into the shaft inlet, oil flow rates in the main and sub-journal bearings and in the eccentric bearing, and oil leakages through roller end clearances into suction and compression chambers. Validation of the numerical simulation was made by measurement of the total oil flow rate into the shaft. With the aid of computer simulation, parametric studies were also carried to investigate the effects of the bearing groove shape and groove inclination angle on the bearing oil flow rates.
