Title:
ROTARY SCREW MACHINE WITH THRUST BALANCED BEARINGS
Document Type and Number:
WIPO Patent Application WO/1993/010333
Kind Code:
A1
Abstract:
In a rotary screw machine a shaft journal (7) of one of the rotors (6) is mounted in main thrust bearings (9, 10) and a balancing thrust bearing (11), the latter being located outermost on the shaft journal (7). The main thrust bearings (9, 10) are clamped towards the low pressure end of the machine. The balancing thrust bearing (11) is affected by a thrust balancing device for counter-acting the gas forces on the rotor (6), thereby reducing the force that has to be transferred by the main thrust bearing.
