Abstract

The utility model relates to an automatic compensating rotating compressor which is mainly composed of a pin (1), a spring (2), a slant key (3), a piston (4), a gas cylinder (5), a shaft sleeve (6), a shaft (7), a positioning pin (8), a slide block (9) and a spring (10). The eccentric part of an eccentric shaft of an original rotating compressor is replaced by an automatic compensating mechanism. The compensation mechanism is formed by that the positioning pin (8) and the slant key (3) are arranged on the shaft (7), the spring (2) is sheathed on the slant key, the shaft sleeve (6) is sheathed on the shaft, a shaft sleeve positioning pin hole is sheathed on the positioning pin, the pin (1) is arranged on the shaft sleeve, and the piston (4) is sheathed on the shaft sleeve. When the shaft is rotated, the piston automatically floats upwards through the slant function of the shaft, gapless movable sealing is formed, and automatic compensation is completed.

Description

Automatically compensate rotary compressor

The utility model relates to daily technical field of living goods, and specifically a kind of being used for compensates rotary compressor on domestic air conditioning and the refrigerator automatically.

At present, rotary compressor generally is used for room air conditioner at home and abroad, used rotary compressor in the homemade air conditioner, basically rely on import, main cause is a rotary compressor machining accuracy height, home equipment can't be made, and the manufacturing difficult point of this compressor mainly concentrates on: guarantee that the gap between outside piston and the cylinder inner wall is not more than 10 microns requirements.The part that influences this gap, place has: eccentric shaft, piston, cylinder and two end caps, above-mentioned five parts are assembled, reach this gap, place and be not more than 10 microns requirements, must rely on high precision machine tool to process each part, building a rotary compressor factory needs a large amount of foreign exchanges from external import high precision machine tool, and its amount of money is often up to several hundred million yuans.

Order of the present utility model ground is a kind of automatic compensation rotary compressor that can utilize homemade conventional equipment to make of design, it adopts compensation mechanism to replace the eccentric part of former compressor eccentric shaft, when compressor shaft rotates, by the ramp effect on the axle, piston is floated automatically, until cylinder inner wall, form the motive sealing of no gap.

The utility model compensates rotary compressor automatically and mainly is made up of: cylinder (5), axle (7), slide block (9), spring (10), piston (4), axle sleeve (6), locating stud (8), inclined-plane strong (3), pin (1), spring (2).

The advantage that the utility model compensates rotary compressor automatically is:

One, available homemade machine tool is made this compressor, has reduced equipment investment and has reduced processing cost.

Two, the automatically piston that causes of compensate for wear and the gap between the cylinder inner wall, its compensation rate can reach 1～2 millimeter, and common rotary compressor should surpass 0.02 millimeter by place's wearing clearance, just scrapped substantially.Therefore, prolonged the compressor life-span behind the employing compensation mechanism.

The contrast accompanying drawing elaborates to embodiment

Figure (1) compensates the rotary compressor structural representation automatically

Shown in figure (1), on axle (7), have a strong groove, the inclined-plane key (3) of packing into, strong groove locates to bore a hole for pairing 180 ° on axle, the locating stud (8) of packing into, load onto the pin (1) that intensity meets the demands in axle sleeve (6) intermediate portion, and locate to bore a hole for pairing 180 ° at pin, again axle sleeve (6) is inserted in axle (7), and axle sleeve (6) is gone up the good borehole jack of brill on locating stud (8), and on pin (1), package spring (2), at this moment axle sleeve (6) can not freely rotate on axle, can only move up and down, at last piston (4) is enclosed within on the axle sleeve (6), load onto end cap at cylinder (5) one ends, to package the axle of piston (4) again, insert ending cover hole and piston is in the cylinder, load onto slide block (9), spring (10) is loaded onto end cap at the other end of cylinder (5) at last.

When axle rotated, under inclined-plane thrust and action of centrifugal force, axle sleeve slided on the inclined-plane of inclined-plane key by pin, drove piston and floated together, was close to cylinder inner wall until piston, formed the motive sealing of no gap.

When axle did not rotate, axle sleeve and piston still were close to cylinder inner wall under the effect of spring.

Because piston is close to cylinder inner wall all the time, thereby formed a kind of novel automatic compensation rotary compressor.

Claims

A kind of automatic compensation rotary compressor, its structure characteristic is: axle (7) is gone up device locating stud (8) and inclined-plane key (3), on the inclined-plane key, be with spring (2), axle sleeve (6) is enclosed within on the axle, and the axle sleeve positioning pin hole is enclosed within on the locating stud, installs pin (1) on axle sleeve, piston (4) is enclosed within on the axle sleeve, when axle rotates,, piston is floated automatically form the motive sealing of no gap, realize compensation automatically by the ramp effect on the axle.
