TRANSLATIONAL ROTOR ROTATING COMPRESSOR

摘要

A translational rotor rotating compressor includes a rotor shaft (1), a rotor (2), a cylinder (3), a vane (4) and an end cover (5). The rotor (2) has a cylindrical outer surface and the cylinder (3) has a circular hole inner surface. The rotor shaft (1), the rotor (2) and the vane (4) are arranged in the cylinder (3); the rotor (2) driven by the rotor shaft (1) is rotationally mounted on the rotor shaft (1); the axis of the outer surface of the rotor (2) is parallel and eccentric with the axis of the inner surface of the cylinder (3), and the outer surface of the rotor (2) is tangentially matched with the inner surface of the cylinder (3). A flat sliding groove (6) provided in the cylinder (3) is parallel with the axis of the cylinder (3), and an outer end of the vane (4) slidingly matched with the sliding groove (6) is fitted in the sliding groove (6). The rotor (2) is cut by a plane so as to form a tangent plane (7) and an inner end of the vane (4) has a flat-shaped plane slidingly matched with the tangent plane (7) of the rotor (2). The translational rotor rotating compressor is used for a cold compressor, an air condition compressor, a gas compressor, a vacuum pump, a hydraulic pump and a water pump.
