Abstract
A rotary compressor comprises a compression component and a motor component which are arranged in a shell. The compression component comprises a cylinder, a slide plate groove, a piston, a crankshaft, slide plates, a main bearing and an auxiliary bearing, the slide plate groove is arranged on the cylinder, the piston is disposed in the cylinder, the crankshaft drives the piston to rotate eccentrically, the slide plates are arranged in the slide plate groove, the main bearing and the auxiliary bearing are respectively disposed on two sides of the cylinder, the motor component comprises a stator and a rotor, the stator is fixed on the inner wall of the shell, the rotor is fixed on the crankshaft, and the slide plates comprise a first slide plate and a second slide plate which are arranged side by side. Two cuts are respectively arranged at one end of the first slide plate and one end of the second slide plate and jointly form a groove, and a rolling needle is arranged in the groove and connected with the periphery of the piston. The groove is arc-shaped or trapezoidal. Besides, the rotary compressor has the advantages of simple and reasonable structure, flexibility in operation, easiness in processing, low manufacturing cost and abrasion rate, high energy efficiency ratio and wide application range.
Description
Technical field
The utility model relates to a kind of compressor, particularly a kind of rotary compressor.
Background technique
The slide plate of common rotary compressor tightly is pressed on the outer surface of piston under the effect of back pressure and spring force, and along with the rotation of piston in cylinder intercycle property, slide plate weares and teares, and is sliding friction between slide plate and the piston.When rotary compressor just came into operation, the loss ratio of the input power of compressor was less; Along with the slide plate wearing and tearing constantly increase, the loss of the input power of compressor also can increase thereupon, thereby influences the working efficiency of compressor.
Chinese patent document number CN2931862Y discloses a kind of compressor on August 8th, 2007, and the slide plate tip has circular hole, is provided with needle roller in the circular hole.Because slide plate is relatively thinner and hardness is higher, processes relatively difficulty of circular hole at single slide plate front end, this structure haves much room for improvement.
The model utility content
The rotary compressor that the purpose of the utility model aims to provide a kind of simple and reasonable, flexible operation, is prone to processing, fabricating cost is low, wear rate is low, Energy Efficiency Ratio is high, applied widely is to overcome deficiency of the prior art.
A kind of rotary compressor by this purpose design; Comprise the compression assembly and the electric machine assembly that are arranged in the housing; Compression assembly comprises cylinder, is arranged on the vane slot on the cylinder; Be arranged on piston in the cylinder, bent axle that driven plunger is made eccentric rotary, be arranged on slide plate, the main bearing that is separately positioned on the cylinder both sides and supplementary bearing in the vane slot, electric machine assembly comprises stator and rotor, and stator is fixed on the inwall of housing; Rotor is fixed on the bent axle, and its structure characteristic is that slide plate comprises first slide plate and second slide plate that is arranged side by side.
One end of said first slide plate and an end of second slide plate are respectively arranged with otch, and two otch are formed groove jointly, and needle roller is arranged in the groove, and the periphery of needle roller and piston is joined.
Said groove is curved or trapezoidal.
Said arc is the great circle arc that central angle surpasses 180 degree.
Said trapezoidal be that up big and down small inversion is trapezoidal.
Slide plate in the utility model is made up of first slide plate that is arranged side by side and second slide plate, and the otch of an end of an end and second slide plate that is positioned at first slide plate is smaller, is easy to shape; The groove of being made up of two otch can effectively prevent the needle roller slippage, has strengthened the Safety performance of rotary compressor,
When rotary compressor is worked,, be rolling friction between needle roller and the piston periphery because the slide plate front end is provided with needle roller.Since adopted rolling friction to substitute sliding friction, can reduce friction and reduce wear intensity, thus can improve efficiency and the working life that prolongs rotary compressor.
The utlity model has simple and reasonable, flexible operation, be prone to processing, fabricating cost is low, wear rate is low, Energy Efficiency Ratio is high, advantage of wide range of application.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1-Fig. 5; This rotary compressor; Comprise the compression assembly and the electric machine assembly that are arranged in the housing 9, compression assembly comprises cylinder 1, is arranged on the vane slot on the cylinder 1, is arranged on piston 2 in the cylinder 1, bent axle 3 that driven plunger 2 is made eccentric rotary, is arranged on slide plate 4, the main bearing 5 that is separately positioned on cylinder 1 both sides and supplementary bearing 6 in the vane slot; Electric machine assembly comprises stator 7 and rotor 8; Stator 7 is fixed on the inwall of housing 9, and rotor 8 is fixed on the bent axle 3, and slide plate 4 comprises first slide plate 10 and second slide plate 11 that is arranged side by side.
One end of one end of first slide plate 10 and second slide plate 11 is respectively arranged with otch, and two otch are formed groove jointly, and needle roller 12 is arranged in the groove, and needle roller 12 joins with the periphery of piston 2.
Above-mentioned groove is curved, and just central angle surpasses the great circle arc of 180 degree; Perhaps, the big up and small down inversion of groove is trapezoidal, and these two kinds of structures all are convenient to needle roller is wrapped in groove, and can prevent effectively that needle roller from deviating from.
Slide plate is pressed in needle roller on the periphery of piston under the effect of back pressure and spring force, and needle roller is done rotation on the one hand in the groove of being made up of jointly first slide plate and second slide plate, on the periphery of piston, roll on the one hand.
