Document Type and Number:
WIPO Patent Application WO/2016/164988
Kind Code:
A3
Abstract:
Compressor element of a screw compressor (1) inlet side (9) and an outlet side (11) and two helical rotors (6 and 7), respectively a male rotor (6) with a drive for the male rotor (6) and a female rotor (7) that is driven by the male rotor (6) by means of synchronisation gearwheels (24 and 25) with at least one synchronisation gearwheel (24) on the male rotor (6), characterised in that the drive and synchronisation gearwheels (24) of the male rotor (6) are chosen such that, upon being driven with acceleration of the rotors (6 and 7) without gas forces, the resulting mechanical drive force that is exerted by this drive and by this synchronisation gearwheel (24) on the male rotor (6) has an axial component (Fp and Fs) that is directed from the outlet side (11) to the inlet side (9) and that the movement of the male rotor (6) in the axial direction (X-X') from the outlet side (11) to the inlet side (9) is fixed by means of a single axial single-acting or double-acting bearing (16).
