Abstract

In a Roots-type rotary positive-displacement compressor (10) comprising two contra-rotating rotors (12, 14) with shafts (16, 189 carrying at one end two gear wheels (38, 40) which are meshed with each other and rendered rigid for rotation with the respective shafts by axial friction-clamping means, a central axial tie rod (48) is inserted through the rotor (12) with which the drive member (42) for the compressor is associated and its shaft (16). This tie rod (48) has screw-threaded ends (48a, 48b) onto which are screwed respective clamping nuts (52, 54) by means of which the drive member (42) and the gear wheel (38) are clamped for rotation with the rotor (12).
