Abstract
The utility model discloses a rotary compressor which comprises a compressing mechanism arranged inside a shell of the compressor. The compressing mechanism comprises a piston, a cylinder, a slip sheet body and a roller pin, wherein the cylinder is provided with a slip sheet slot for accommodating the slip sheet body; the head part of the slip sheet body is provided with a slot; and the roller pin is arranged in the slot of the slip sheet body and abuts against the outer circumference of the piston. The rotary compressor is characterized in that the two end surfaces of the slip sheet body are provided with oil supply slots, and the two end surfaces of the roller pin are provided with oil storage holes. The width of each oil supply slot is L1, the thickness of the slip sheet body is L, the L1 is less than 60% of the L, and the oil supply slots deflect to the gas intake side of the cylinder. The diameter of each oil storage hole is d, the diameter of the roller pin is D, the d is less than 60% of the D, and the center of each oil storage hole is the same with the center of the roller pin. As the oil supply slots are opened on the end surfaces of the slip sheet body, and the oil storage holes are formed at the both end surfaces of the roller pin, during the working of the compressor, a lubricating oil film is formed on the roller pin and the head of the slip sheet body, so that the wear of a slip sheet of the compressor can be reduced effectively, the service life of the compressor is prolonged, and the operation reliability of the compressor is improved.
Description
Technical field
The utility model relates to a kind of rotary compressor.
Background technique
In the existing compressor arrangement, some manufacturer installs needle roller in order to reduce the friction between piston periphery and the slide plate head at the slide plate head.Disclose a kind of compressor such as Chinese patent literature notification number CN2931862Y on August 8th, 2007, as shown in Figure 1, this rotary compressor slide plate top is provided with perforate, is provided with needle roller in the perforate, and described perforate is circular hole or wedge slot.This structure purpose is the way of contact of slide plate head and piston periphery change, becomes needle roller by common slide plate and the sliding contact of piston and contacts with the rolling of piston, and then reduce the power that enters of compressor.Need in the said structure to guarantee a precondition that being needs to form the oil film that can carry between needle roller and groove.Needle roller and slide plate head tapping and local compression can be very high, if oil-free lubrication, without oil film carrying, the wearing and tearing of this position are inevitable severe.Therefore, be necessary to be further improved.
The model utility content
The purpose of this utility model aim to provide a kind of simple and reasonable, cost of production is low, the rotary compressor of long service life, to overcome deficiency of the prior art.
A kind of rotary compressor by this purpose design, comprise the compressing mechanism that is arranged in the compressor housing, compressing mechanism comprises piston, cylinder, slide plate body and needle roller, wherein be provided with the vane slot of taking in the slide plate body on the cylinder, slide plate body head is provided with fluting, and needle roller is installed in the slide plate fluting, and needle roller and piston periphery are inconsistent, its structure characteristic is that slide plate body both ends of the surface have oil supply, and the needle roller both ends of the surface are provided with oil storage hole.
Described oil supply width is L1, and the slide plate body thickness is L, and L1＜L*60% is then arranged, and oil supply deflection cylinder suction side.The oil storage hole aperture is d, and the needle roller diameter is D, and d＜D*60% is then arranged, and the center of oil storage hole is identical with the needle roller center.
Described needle roller be positioned in the cylinder described needle roller height≤slide plate body height after the slide plate body matches.Described oil supply is shaped as semicircle or wedge shape.
The utility model is by offering oil supply and in the needle roller both ends of the surface oil storage hole being set at slide plate body end face, in the compressor operating process, needle roller and slide plate body head can form lubricant film, can effectively reduce the slide plate wearing and tearing of compressor, prolong the working life of compressor, improved the reliability of compressor operating.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 2, a kind of rotary compressor, comprise the compressing mechanism that is arranged in the compressor housing, compressing mechanism comprises piston 1, cylinder 2, slide plate body 3 and needle roller 5, and wherein cylinder 2 is provided with the vane slot 4 of taking in slide plate body 3, and slide plate body 3 heads are provided with fluting, needle roller 5 is installed in the slide plate fluting, needle roller 5 is inconsistent with piston 1 periphery, and slide plate body 3 both ends of the surface have oil supply 6, and needle roller 5 both ends of the surface are provided with oil storage hole 7.
Referring to Fig. 3-Fig. 4, slide plate body 3 end faces offer oil supply 6, and slide plate body 3 thickness are L, oil supply 6 width are L1, are not communicated with in order to guarantee compressing mechanism suction air cavity, guarantee its seal request, oil supply 6 width L1＜L*60% are then arranged, and oil supply 6 is partial to the suction side setting as far as possible.Referring to Fig. 5-Fig. 6, needle roller 5 end faces offer oil storage hole 7, and needle roller 5 external diameters are D, and oil storage hole 7 footpaths are d, in order to guarantee that compressing mechanism suction air cavity is not communicated with, guarantee its seal request equally, and oil storage hole 7 aperture d＜D*60% are then arranged.Oil storage hole 7 centers are identical with needle roller 5 centers, in case needle roller 5 gyrating masses are asymmetric.
The utility model is by arranging oil supply 6 in slide plate body 3 both ends of the surface, because slide plate body 3 afterbodys are high pressure, lubricant oil can feed to needle roller 5 from afterbody, and then enters into the fitting surface of needle roller 5 and slide plate body 3.Needle roller 5 both ends of the surface are provided with oil storage hole 7 in addition, and oil storage hole 7 can store a part of lubricant oil in the compressor operation process, are conducive to the lubricated of needle roller 7 and bearing surface.The utility model can improve the wearing and tearing of slide plate body 3 and needle roller 5, prolong the working life of compressor, and it has the advantages that simplicity of design is reasonable, fabricating cost is low.
