Title (EN) A SINGLE SCREW COMPRESSOR
(FR) COMPRESSEUR A UNE SEULE VIS
Abstract: front page image
(EN)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° and 66°. 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.
(FR)L'invention concerne un compresseur à une seule vis se composant d'un axe principal, d'un corps, d'une vis et d'une roue hélicoïdale. Les dents de la vis ainsi que les dents de la roue présentent une largeur variable. Par ailleurs, le diamètre de la vis varie le long de son axe. Les dents de la roue qui s'imbriquent avec les rainures de la vis forment un angle allant de 60 à 66°. Ce compresseur, de dimension compacte, fait preuve d'un déplacement amélioré, d'une efficacité élevée, d'une durée de vie prolongée et présente un boîtier très rigide.
