Description
Technical field
The utility model relates to a kind of anti-self-rotating mechanism of scroll compressor.
Background technique
Scroll compressor is with its compact structure, energy-efficient and high reliability at present, by the automobile industry extensive use, usually, scroll compressor is mainly by module compositions such as casing, end cap, movable orbiting scroll, quiet whirlpool dish, anti-self-rotating mechanism, bent axle, bearing, clutches.And the relatively quiet whirlpool of movable orbiting scroll molded line dish-type line is eccentric and differ the opposed installation of 180 degree and form a series of crescent-shaped spaces in compressor, i.e. element volume.Movable orbiting scroll is connected with bent axle with eccentric by bearing, bent axle is under the driving of clutch pack, drive movable orbiting scroll in the situation that to have anti-self-rotating mechanism to take quiet whirlpool disk center be rotating center, and do the revolution translation without rotation with certain turning radius, in the revolution process, the outer ring crescent-shaped space just can constantly move to center, element volume is constantly dwindled and pressure constantly raises, until communicate with the central row pore, thereby pressurized gas are discharged to compressor.
During compressor operating, movable orbiting scroll is subject to the effect of axial gas forces, radial force and tangential force etc., because the gas tangential force does not overlap with the crankshaft center of movable orbiting scroll, form the spin moment of movable orbiting scroll, because guarantee the correct engagement of molded line, two whirlpool dishes guarantee the angular position of 180 ° all the time, do not allow movable orbiting scroll generation rotation phenomenon, so this spin moment must be limited.Therefore to realize the revolution translation of the relatively quiet whirlpool of movable orbiting scroll dish, an anti-self-rotating mechanism must be arranged.Existing scroll compressor generally adopts cross slip-ring mechanism, spherical mechanism and double-pin ring mechanism to realize the revolution of movable orbiting scroll and not rotation.
But the cross slip-ring anti-rotation mechanism, it is very high to the perpendicularity requirement of crosshead shoe and cross chute, and again because there being four pairs of sliding friction pairs, frictional force and wearing and tearing are large, cause machining accuracy high, and cost is high.
The required part of spherical anti-rotation mechanism is many, and accuracy of manufacturing is high, the size detection difficulty, and assembling difficulty is large, is unfavorable for reducing costs.
Double-pin ring anti-rotation mechanism is comprised of a ring of two pins, and it is in the process of anti-rotation, and the power of two pins all acts on a ring, reduces the life-span of ring, thereby reduces the working life of compressor.
