Abstract
PURPOSE: To prevent gnawing caused by fretting and the like of a reverse thrust in a screw compressor for car air-conditioning by providing a bearing to bear the reverse thrust on the gas-suction side of a male rotor.
CONSTITUTION: A thrust needle bearing 30 is provided to bear the thrust load given by a reverse thrust on the suction-side shaft-end of a male rotor 5 in addition to radial bearings 7 and 9 provided on the both shaft-ends to bear radial loads and thrust bearings 12 and 13 provided on the discharge-side shaft-end to bear thrust loads. The thrust needle 30 provided thereon serves not only to bear the reverse thrust but to remove the so-called clearance given intially along the rotor shaft, and prevents gnawing and fretting.
