Abstract

The invention relates to an oil-free scroll air compressor, comprising a fixed scroll, a movable scroll, a crankshaft, a frame, a main balance weight, a pulley, an air suction port and an exhaust port, and the movable scroll It meshes with the fixed scroll to form an air compression chamber; the crankshaft is installed in the frame with the main bearing and the auxiliary bearing, and a ball disc structure is arranged between the movable scroll and the frame. The ball disc structure includes a mounting On a fixed seat of the frame, a radial bearing and a thrust bearing are arranged on the fixed seat, and the fixed seat is provided with a mounting hole, and the radial bearing is fixed in the mounting hole and installed on the eccentric shaft at one end of the crankshaft; The thrust bearing is fixed on one side of the fixed seat and is closely attached to the side of the frame; the radial bearing and the thrust bearing are concentric shafts, and the thrust bearing ring is set outside the radial bearing, so that the movable scroll and the static scroll During relative rotation, the movable scroll drives eccentric rotation through the radial bearing on the eccentric shaft, and is positioned and rotated through the thrust bearing, so that a good phase difference is maintained between the movable scroll and the fixed scroll. The invention has the characteristics of simple structure, low cost, stable rotation performance and the like.

Description

technical field [0001] The invention relates to an air compressor, in particular to an oil-free scroll air compressor. Background technique [0002] Scroll air compressors are widely used in industrial, agricultural, transportation and other industries where compressed air is needed due to their high efficiency, low noise, small size, and benefits for energy saving and environmental protection. The main running part of the scroll air compressor is meshed with the scroll, which does not cause wear and tear, so the service life is longer than that of the piston and screw compressors, and it is an ideal power source for pneumatic machinery. In the scroll air compressor, the scroll of the main moving parts is divided into a moving scroll and a fixed scroll, and the moving scroll and the fixed scroll are equipped with scroll plates. The rotary disks are combined with each other to form a compression chamber. When the movable scroll is driven by the crankshaft to move along a cer...
