ROLLER BLADE MACHINE Russian patent published in 2000 - IPC

FIELD: performing function of hydraulic drives, pumps and compressors; mechanical engineering; oil, chemical and other industries. SUBSTANCE: sectional shell of rotor is provided with blades on inner surface which have different length in compression stages. One end of shell rests against end plate pressed on shaft of machine drive and its other end is supported by bearing. Arranged inside shell is sectional core whose one end is secured to one of end plates of machine. Core is pressed on central fixed rod whose one end is secured in end plate to which core is secured and other end is supported by bearing of other end plate; this bearing is located inside hollow shaft of drive of machine. Core is provided with grooves for receiving rollers-separators interconnected along axis of rotation by compression stages. Synchronizing gears are common for rollers- separators of all compression stages. Working medium inlet and outlet passage are connected in succession by stages. Inter-roller chambers of each stage are formed between core, rotor shell and respective rollers- separators of each stage. EFFECT: reduced usage of metal; extended field of application. 3 dwg
