<p>A single screw compressor is comprised of a main shaft, a housing, a screw and planet gears. The teeth of the screw are not equal in width, so are that of the planet gears. The diameter of the screw is varied along its axis. At the beginning of the teeth of the planet gears engaging with the gullet of the screw, the closed angle therebetween is in the range of 60 DEG and 66 DEG . The advantage of the invention resides in increasing the displacement of compressor, and efficiency, reducing the volume, improving the rigidity of bracket, and prolonging the service life.</p> |
