Abstract
The present invention relates to a vortex compressor, which aims to achieve the oil-free lubrication of the compressor, reduce overturning moment generated by gas force and centrifugal inertia force to a movable vortex disk, raise the working stability of the compressor and prolong the service life of a driving bearing. An autorotation preventing mechanism is composed of the movable vortex disk (4), a small crank (6), a bearing (7) and a supporting embedded iron (8), wherein the upper end of the small crank (6) is embedded on an end plate of the movable vortex disk (4) through the bearing (7), the lower end of the small crank (6) is arranged in the supporting embedded iron (8), and the supporting embedded iron (8) is arranged on a supporting rack body (13). The driving bearing (5) is embedded in the central position of the movable vortex disk (4), a vortex disk end surface of the movable vortex disk (4) contacting the supporting embedded iron (8) is provided with self-lubricating materials (10), and the contacting surface of a static vortex disk (3) and the movable vortex disk (4) is provided with self-lubricating materials (9).
Description
Technical field
The present invention relates to the scroll compressor in the fluid capacity-changing mechanism.
Background technique
The main parts size of scroll compressor has: moving scroll, fixed scroll, stake body, bent axle, motor etc.The molded lines of dynamic and static scroll wrap is identical, and 180 ° of phase dislocations are eccentric settles, and dynamic and static scroll wrap engagement forms the closed compression chamber, and the medium ecto-entad gradually reduces, and realizes air-breathing, compression and exhaust.Each friction pair is oil jet lubrication in common scroll compressor structure, moving vortex driving bearing is placed in the moving vortex disk outside, this structure is because gas force action plane and moving vortex centrifugal matter power effect plane and moving vortex drive not coplane of plane, thereby produce tilting moment to moving vortex, cause the compressor operating state labile, shorten working life, and contain oil in the oil jet lubrication compressed media, and its use occasion is restricted.
Summary of the invention
The objective of the invention is to realize the compressor oil-free lubrication, reduce gas force and centrifugal inertia force, increase the stability of compressor operating, prolong the driving bearing target in working life the tilting moment that moving vortex produces.
The present invention is a kind of scroll compressor, bent axle (15) is installed on the stake body (13), motor stator (17) links with stake body (13), rotor (18) is directly installed on the bent axle (15), drive moving scroll (4) and do the revolution translation, scroll wrap on the moving scroll (4) and the scroll wrap on the fixed scroll (3) interlace and settle engagement, form the closed compression chamber, by moving scroll (4), little crank throw (6), bearing (7) and supporting embedding iron (8) are formed anti-rotation mechanism, the upper end of little crank throw (6) is embedded on the end plate of moving scroll (4) by bearing (7), the lower end is installed in the supporting embedding iron (8), and supporting embedding iron (8) is installed on the stake body (13).Driving bearing (5) is embedded in the center portion of moving scroll (4).
Moving scroll (4) is provided with self lubricating material (10) with the contacted scroll end face of supporting embedding iron (8), fixed scroll (3) is provided with self lubricating material (9) with the surface of contact of moving scroll (4), the exhaust side of fixed scroll (3) is provided with cooling water channel (11), and the outside of motor stator (17) is provided with cooling water channel (12).
Major advantage of the present invention: (1) compressed medium realizes the clean oil that do not have.(2) tilting moment that produced of the gas force that born of moving vortex driving bearing and moving vortex centrifugal inertial force reduces, and has increased the stability of compressor operating, has prolonged working life.(3) cooling water channel can reduce the temperature of gas in the compression process and the heat that machine operation produces, and reduces power consumption.(4) compact structure is simple.
