Wear-preventing and positioning device for a screw compressor

A screw compressor includes a suction end, a discharge end, first and second rotors mounted for rotation between the suction end and the discharge end, and a discharge housing at the discharge end. The discharge housing surrounds a portion of the first and second rotors and includes an end surface....

Beschreibung
Zusammenfassung:	A screw compressor includes a suction end, a discharge end, first and second rotors mounted for rotation between the suction end and the discharge end, and a discharge housing at the discharge end. The discharge housing surrounds a portion of the first and second rotors and includes an end surface. The compressor further includes a first axial bearing supporting the first rotor, 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 contacts the end surface. The screw compressor further includes a first radial bearing in the discharge housing for supporting the first rotor. The wear-preventing member includes a face abutting the end surface of the discharge housing and abutting at least a portion of the first radial bearing to retain the first radial bearing in the discharge housing.
