Closed-type high-reliability anti-autorotation oil-free vortex air compressor

Abstract

The invention discloses a closed-type high-reliability anti-autorotation oil-free vortex air compressor. The closed-type high-reliability anti-autorotation oil-free vortex air compressor comprises a dynamic disc (1) and a static disc; the static disc is fixedly arranged in a shell (3); a moulding line end of the dynamic disc (1) is inserted into a moulding line end in the static disc; the other end of the dynamic disc (1) is connected to a crankshaft (5) through a bearing (4); the closed-type high-reliability anti-autorotation oil-free vortex air compressor is characterized in that an oil groove (6) used for providing oil for lubrication is formed in the outer side of the bearing (5); the oil groove (6) does not communicate with an air compression passage between the dynamic disc and the static disc; limiting cylindrical pins are fixedly arranged on the outer circle of the end, which is not inserted into the static disc, of the dynamic disc (1); a limiting ring sheet is arranged on the shell; and round holes of the same number as the limiting cylindrical pins are formed in the limiting ring sheet and are used for the limiting cylindrical pins to be inserted in so as to limiting planar swinging of the dynamic disc. The closed-type high-reliability anti-autorotation oil-free vortex air compressor is simple in structure, low in manufacturing cost and good in lubrication performance.

Description

technical field [0001] The invention relates to an oil-free air compressor technology, in particular to an oil-free air compressor for high-speed rail, in particular to a closed, high-reliability anti-rotation oil-free scroll air compressor for high-speed rail equipment. Background technique [0002] The compressed air used by high-speed rail equipment must be oil-free compressed air. Although the current vane-type and piston-type oil-free air compressors can meet its requirements, both vane-type and piston-type oil-free air compressors have large volume , High manufacturing cost and difficult installation and maintenance have affected its popularization and application on high-speed rail equipment. The scroll air compressor has the problems of small size and convenient manufacture and installation. However, the traditional scroll air compressor for vehicles cannot be directly applied to oil-free air compressors because the compression medium itself has a lubricating effect....
