Abstract (en)
[origin: US6488488B2] The drive gear 19, 21 and the synchronizing gear 25, 27 for the two rotors 9,11 of a screw compressor are both located at the pressurized end of the rotor housing 3. At the suction end of the rotor housing 3 is only the bearing 53 for the suction side shaft journal 55, 57 that is free of oil lubrication. Inlet openings 13 in a suction side inlet housing are located in such a way that the intake air cools the oil-free shaft bearing 53. Each shaft journal has a tool interface 63 accessible through the inlet housing on which to attach a rotating tool. The inlet housing 4 can be removed from the shaft journal 55, 57 together with the bearing 53 and seal 87, for example to exchange the bearing, without having to remove the rotors 9, 11 or without throwing off their adjustment.
