Influence of Profile Parameters on Radial Leakage Line Length of Variable Tooth Thickness Scroll Compressor

Abstract

In order to accurately calculate the radial length of leak line of scroll compressor of variable tooth thickness, with three sections of circle involute type of scroll line as the research object, according to the type line equation to obtain the geometric model of variable tooth thickness radial leakage line length calculation model was set up, numerical solution, through accurate profile parameters was studied (Base circle radius, Connection point, Turning radius, etc.) on the influence of the length of leak line of change. Results show that the model could accurately describe the radial length of leak line of instantaneous change rule, and got the type line parameter change on the influence of the radial length of leak line of law, and the best control the length of leak line type line parameters, providing theoretical basis for reducing radial leakage scroll compressor, at the same time, the model also applies to other type line leak line length calculation.
