摘要
This paper introduces a new meshing pair profile envelope by multicolumn in single screw compressors. The screw groove flank of the new meshing pair is a multisegment surface, and the star-wheel tooth flank consisted of multicylindrical surfaces. When the compressor is operating, the position of the contact line on the tooth flank with the screw groove flank uniformly moves in one revolution, which is rather different from the stationary contact position of existing meshing pair profiles. The new meshing pair will result in the improved wear-resistance and longer operation life, lower gas leakage, and higher efficiency of the compressor.
