Abstract:
A screw compressor comprising:a suction end; a discharge end; first and second rotors mounted for rotation between the suction end and the discharge end, each of the first and second rotors being capable of some axial movement with respect to the discharge end; a discharge housing at the discharge end and surrounding a portion of the first and second rotors, the discharge housing having an end surface; a first axial bearing supporting the first rotor, the first axial bearing having an outer race that is axially movable with respect to the end surface; and a wear-preventing member sandwiched between the end surface of the discharge housing and the first axial bearing such that no portion of the first axial bearing can contact the end surface, the wear-preventing member being substantially prevented from rotating with respect to the end surface.
