Abstract
A rotary compressor comprises a compression component arranged in a casing, wherein the compression component is provided with a cylinder, a slip sheet groove is arranged on the cylinder, and a slip sheet is arranged in the slip sheet groove. The thickness of an exhaust side at a tail part of the slip sheet is smaller than that of the slip sheet; and a gap used for lessening the weight of the slip sheet and reducing the rigidity of the tail part of slip sheet simultaneously is arranged on an air suction side at the tail part of the slip sheet. The length of the gap is not more than the half of the total length of the slip sheet; and the thickness of the exhaust side at the tail part of the slip sheet is not less than one eighth of the thickness of the slip sheet. The section of the gap takes the shape of a strip, a wedge or an arc. The gap is arranged at the tail part of the slip sheet, so that the weight of the slip sheet can be reduced, and the friction between the slip sheet and an auxiliary bearing is reduced; and meanwhile, the deflection of the tail part of the slip sheet is enhanced, the metal contact area between the side surface of the slip sheet and the surface of the slip sheet groove is enlarged, the boundary lubrication area is enlarged, and the pressure of an oil film is increased, thereby improving the lubrication of a contact surface, and finally achieving the effect of reducing the power consumption of the compressor.
Description
Technical field
The utility model relates to a kind of rotary compressor.
Background technique
Referring to accompanying drawing 1-Fig. 3, be rotary compressor of the prior art, form compression assembly by cylinder 1, piston 2 and slide plate 3 etc.Piston 2 is arranged in the compression chamber of cylinder 1, and cylinder 1 is provided with vane slot, is provided with the slide plate 3 that can move back and forth in the vane slot, by piston 2 and slide plate 3 compression chamber of cylinder is divided into air aspiration cavity and exhaust cavity.When rotary compressor is worked, slide plate 3 to-and-fro motion, because the existence of slide plate 3 deadweight, slide plate 3 can produce friction with the supplementary bearing that is positioned at below the cylinder 1, simultaneously, the frictional force between gas pressure and vane slot and the slide plate 3 has also been born in the side of slide plate 3.
Because exhaust pressure is much larger than pressure of inspiration(Pi), make and produce frictional force between the radial surface of the afterbody side of slide plate 3 and vane slot, this two surface of contact overwhelming majority is a Metal Contact, and, the lubricated area on border is less, so cause frictional force bigger, yet the big more power consumption that is embodied directly in rotary compressor of frictional force strengthens, efficient reduces.
The model utility content
The purpose of this utility model aims to provide a kind of simple and reasonable, technology is simple, friction power loss is little, applied widely rotary compressor, to overcome deficiency of the prior art.
A kind of rotary compressor by this purpose design, comprise the compression assembly that is arranged in the housing, compression assembly comprises cylinder, cylinder is provided with vane slot, be provided with slide plate in the vane slot, its structure characteristic is the thickness of thickness＜slide plate of exhaust side of the afterbody of slide plate, and the suction side of the afterbody of slide plate is provided with breach.
1/2 of the length of described breach≤slide plate total length, 1/8 of the thickness of the thickness 〉=slide plate of the exhaust side of the afterbody of slide plate.
The exhaust side of the afterbody of described slide plate also is provided with groove, and groove communicates with breach.
The bottom of described groove is to 1/8 of the thickness of the distance 〉=slide plate of the outer rim of the exhaust side of the afterbody of slide plate, the bottom of the thickness＞groove of the exhaust side of the afterbody of slide plate is to the distance of the outer rim of the exhaust side of the afterbody of slide plate, 1/2 of the length of breach≤slide plate total length.
The cross section of described breach is stick shape, wedge shape or arc.
Because slide plate is in the time spent of doing that is subjected to gas force, the slide plate that is arranged in vane slot is tendency one side, it is the front end tendency suction side of slide plate, the tail end tendency exhaust side of slide plate, therefore, the tail end of slide plate just breaks away from the suction side of vane slot, and the suction side surface of vane slot can't contact with the suction side of the tail end of slide plate, slide plate just do not exist to be subjected to force phenomenon, so can not need this part.Therefore, the utility model is provided with breach at the afterbody of slide plate, both can alleviate the quality of slide plate, reduces the friction at slide plate and supplementary bearing place; Simultaneously, can also strengthen the amount of deformation of slide plate afterbody, reduce the metal contact area between the surface of the side of slide plate and vane slot, strengthen the boundary lubrication area, thereby increase oil film pressure and improved the lubricated of contact surface, finally reach the effect that reduces the compressor power consumption.
The utlity model has simple and reasonable, technology is simple, friction power loss is little, advantage of wide range of application.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 4-Figure 12, this rotary compressor, comprise the compression assembly that is arranged in the housing, compression assembly comprises cylinder 1, cylinder 1 is provided with vane slot, be provided with slide plate 3 in the vane slot, the thickness of the thickness＜slide plate of the exhaust side of the afterbody of slide plate 3, the suction side of the afterbody of slide plate 3 is provided with the quality that is used to alleviate slide plate 3 and reduces the breach of rigidity of the afterbody of slide plate 3 simultaneously.1/2 of the length a of breach≤slide plate 3 total lengths, 1/8 of the thickness c of the thickness b 〉=slide plate 3 of the exhaust side of the afterbody of slide plate 3.
When the thickness c of the thickness b 〉=slide plate 3 of the exhaust side of the afterbody of slide plate 3 1/4 the time, can obtain better technique effect.
