Title:
SCREW COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2013/187181
Kind Code:
A1
Abstract:
A screw compressor (1) comprises a screw rotor (4), a rotor shaft (11) structurally integrated with a male rotor (4a) of the screw rotor (4) coaxially with the male rotor (4a), a motor part (8) (motor) for causing the rotor shaft (11) to rotate, and a bearing (14) for cantileverably supporting the motor by supporting a portion of the rotor shaft (11) between the screw rotor (4) and the motor. Providing a notched part (16) causes the bending rigidity of a portion of the rotor shaft (11) between the shaft bearing (14) and a rotor (5) of the motor to differ in two orthogonal directions (x-axis direction, y-axis direction) crossing each other in the rotor shaft (11).
