PCT No. PCT/SE92/00767 Sec. 371 Date Apr. 12, 1994 Sec. 102(e) Date Apr. 12, 1994 PCT Filed Nov. 5, 1992 PCT Pub. No. WO93/10333 PCT Pub. Date May 27, 1993.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. |
