COMPRESSOR ELEMENT FOR SCREW COMPRESSOR (EMBODIMENTS) AND SCREW COMPRESSOR Russian patent published in 2019 - IPC F04C18/16 F04C29/00 

FIELD: machine building.

SUBSTANCE: group of inventions relates to compressor element of screw compressor. Compressor element (2) comprises housing (4) with inlet and outlet holes at inlet and outlet sides (9, 11) respectively and two rotor chambers (5), in which driving rotor (6) with drive and driven rotor (7) are installed, driven by rotor (6) by means of synchronizing gears (24 and 25). At least one wheel (24) is located on rotor (6) and one wheel (25) is located on rotor (7). Drive and wheels (24) are selected so that at actuation with acceleration of rotors (6 and 7) without forces acting on gas side, resultant mechanical drive force, which is applied by means of drive and wheel (24) to rotor (6), comprises axial component directed from side (11) to side (9). Rotor (6) is fixed against movement in axial direction (X-X') from side (11) to side (9) by means of axial bearing (16). Rotor (6) drive is located on side (9). Wheels (24 and 25) are located on side (11), and bearing (16) is located on side (11). Rotor (6) is installed by means of two radial bearings (14, 15). Bearings (14, 15) are located on sides (9, 11) respectively.

EFFECT: group of inventions is aimed at synchronization of rotors.
