The scroll compressor has two leakage passes, which are the gap in an axial direction at the tip of the wrap and the gap in a radial direction between the wraps. Many attempts to reduce the leakage through those gaps have been actively researched and developed. In this study, we grasped the characteristics of the contact force between the wraps of a CO2 scroll compressor with the fixed orbiting radius by measuring the oil-film pressure at the main bearing. In addition, we developed the analytical method to simulate the contact force considering the effect on the formation of oil-film at the bearings and move constrain of the orbiting scroll. As a result, we found that (1) there is a fluctuation of the contact force at one revolution, (2) the contact force increases with rotational speed, (3) the contact force has little change for operating condition and (4) contact force increases with decreasing the wrap clearance.
