Abstract
The utility model relates to a volumetric vortex fluid compressor, which relates to the fluid machinery technical field. The volumetric vortex fluid compressor comprises a still vortex disc, a moving vortex disc, and a suction cavity chamber which are installed in the housing. The outside of the main shaft crankpin of the volumetric vortex fluid compressor is provided with an articulation balance block, which is installed in the bearing saddle bore of the moving vortex disc by a bearing; the inner of the main shaft is provided with an oil bore, which is communicated with the outer surface of the crankpin positioned on the inner of the bearing saddle bore of the moving vortex disc, the end face of the crankpin, and cavity chamber outside the bearing saddle bore of the moving vortex disc. The utility model is used for compressing to the fluid; compare with prior art, the volumetric vortex fluid compressor can solve problems that the adjoining plane of the crankpin of the compressor and the articulation balance block and the driving bearing of the moving cortex disc have bad lubrication.
Description
Technical field
The utility model relates to the fluid machinery technical field, especially a kind of device by dynamic and static scroll engagement compressed fluid.
Background technique
Displacement vortex fluid compressor is realized the convection cell compression by the relative gear motion of dynamic and static scroll, its moving scroll is by main shaft drives, this main shaft has a shaft shoulder portion that is used to be contained in the main bearing endoporus, be connected with the concentric axle journal coaxial at this shaft shoulder portion one end with shaft shoulder portion, the other end in this shaft shoulder portion is connected with the eccentric crank pin that is provided with shaft shoulder portion, is set with joint balance piece, this joint balance piece and then is used for driving the bearing saddle bore that the bearing that moves the scroll motion is contained in the moving scroll back side by one outside the spindle crank pin.This structure makes lubricant oil be difficult to enter in the above-mentioned bearing of the mating face of crank pin and joint balance piece and band edge lid, and therefore, these positions are easy to take place oil starvation, even oil-free lubrication, therefore break down.
Summary of the invention
The utility model provides a kind of displacement vortex fluid compressor, the problem of the driving bearing insufficient lubrication of its crank pin in can solving device and joint balance piece mating face and moving scroll.
For achieving the above object, the scheme that the utility model adopts is: it includes the fixed scroll that is contained in the housing, moving scroll, the chamber that is communicated with the suction port that constitutes by fixed scroll and moving scroll, its main shaft has a shaft shoulder portion that is used to be contained in the main bearing endoporus, at an end of this shaft shoulder portion is concentric shafts with the coaxial setting of shaft shoulder portion, the other end in this shaft shoulder portion is and the eccentric crank pin that is provided with of shaft shoulder portion, outside described crank pin, be set with the joint balance piece, this joint balance piece is contained in the bearing saddle bore of described moving scroll by bearing, be provided with oilhole in the described main shaft, this oilhole is communicated with the outer surface that described crank pin is positioned at described moving scroll bearing saddle bore, the described chamber that the end face of described crank pin and described moving scroll bearing saddle bore are outer.
An outlet of above-mentioned oilhole can be located on the outer surface of described concentric shafts.An outlet of above-mentioned oilhole also can be located at described crank pin and be positioned on the outer surface of described moving scroll bearing saddle bore, and is right against at described joint balance piece on the hole wall at this outlet position and is provided with a passage inside and outside the connection hole wall at least.Above-mentioned oilhole also can be provided with plural outlet simultaneously, one of them outlet is located on the outer surface of described concentric shafts, another oilhole is located at described crank pin and is positioned on the outer surface of described moving scroll bearing saddle bore, and is right against at described joint balance piece on the hole wall at this outlet position and is provided with a passage inside and outside the connection hole wall at least.
Owing to adopted such scheme the utility model compared with prior art to have following beneficial effect:
The effective problem of the driving bearing insufficient lubrication of the crank pin in the solving device and joint balance piece mating face and moving scroll.Owing to be provided with oilhole in main shaft, this oilhole is communicated with outer surface, the end face of described crank pin and the chamber outside the described moving scroll bearing saddle bore that described crank pin is positioned at described moving scroll bearing saddle bore.Therefore, during this device busy, fluid in the intake chamber and miscella can import in the driving bearing of crank pin and joint balance piece mating face and moving scroll, thereby guarantee the lubricated good of these positions.
