Abstract
The utility model discloses a novel oil supply structure of a refrigeration compressor, which comprises a crankshaft and an oil suction pipe. The lower portion of the crankshaft is a main shaft, an inner hole of the main shaft is in clearance fit with the oil suction pipe, a spiral spring which spirals upwards along the inner wall of the oil suction pipe is attached to the inner side of the oil suction pipe, a central spindle stands in the oil suction pipe, the rotating direction of the upward spiraling of the spiral spring is opposite to that of the oil suction pipe, and the central shaft is fixed by a steel wire which penetrates through the lower portion of the central spindle. According to the novel oil supply structure of the refrigeration compressor, the spiral spring which spirals upwards along the inner wall of the oil suction pipe is attached to the inner side of the oil suction pipe, the spiral spring simultaneously rotates when the oil suction pipe rotates, a spiraling oil supply channel is formed between the oil suction pipe and the central shaft due to the fixed central shaft, and refrigeration oil easily reaches the top of the main shaft by aids of a centrifugal force.
Description
Technical field
The utility model relates to refrigeration compressor, is specifically related to the oil supply structure at refrigeration compressor fuel sucking pipe place.
Background technique
The oil pump of refrigeration compressor is realized lubricated to moving element through centrifugal, the spiral mode of oiling, and moving element comprises cylinder seat, bent axle, piston, wrist pin, connecting rod.Each component obtain lubricated after, can reduce the wearing and tearing of friction pair between each part, reduce the complete machine power loss, improve compressor working life.In addition, the lubricant oil that oil pump provides can play the effect of cooling to each part of compressor inside, has improved the reliability of each part.
Conventional decide the rotating speed refrigeration compressor, fuel sucking pipe immerses in the oil sump, the oil sump liquid level height according to refrigerator or refrigerator refrigerant system design and oil pump oil require definite; Bent axle rotates and drives fuel sucking pipe and rotates with rotating speed, and the refrigeration oil in the fuel sucking pipe is the very fast and same rotating speed of fuel sucking pipe under the blade effect, and first gets rid of oilhole to refrigeration oil to bent axle in the centrifugal action elevated height along the fuel sucking pipe inwall; Accomplish the first order fuel feeding of compressor; After refrigeration oil gets rid of oilhole and throws away from first, rise to the main shaft upper-end surface through the spiral finishing bathtray of main shaft part and go into oilhole, accomplish the second level fuel feeding of compressor; The refrigeration oil inclined hole that main shaft is connected with eccentric shaft of under centrifugal action, flowing through again; Accomplish third level fuel feeding, the final realization got rid of oil, thereby realized the lubricated and cooling of each part friction pair of compressor moving element.The wherein small aperture and the fuel sucking pipe inner diameter that oil and highly depend on the fuel sucking pipe lower end of first order fuel feeding.On the constant speed refrigeration compressor, adopt this structure, be easy to realize oiling.For slow-speed of revolution compressor or the less thin bent axle compressor of main shaft diameter, the lubrication ratio of realizing each component through conventional oil supply structure is difficulty, and is little or do not have refrigeration oil to throw away in the crankshaft eccentric shaft oil pump capacity.
The model utility content
The purpose of the utility model is to provide a kind of novel oil supply structure of refrigeration compressor, has novel structure, puies forward the effective advantage of oil.
The utility model to achieve these goals, the technical solution of employing is:
The novel oil supply structure of refrigeration compressor comprises bent axle and fuel sucking pipe, and the bottom of bent axle is a main shaft, and the endoporus interference of main shaft is equipped with fuel sucking pipe; Post the helical spring that rises around the fuel sucking pipe spiral inner wall in the said fuel sucking pipe, standing in the fuel sucking pipe has mandrel.
Further, said helical spring spiral rising sense of rotation and fuel sucking pipe direction of rotation.
Further, the cross section of said helical spring spring thread is a rectangular.
Further, the cross section of said helical spring spring thread is circular.
Further, said mandrel is by the Fixation With Steel Wire of passing the mandrel bottom.
The beneficial effect of the utility model:
The novel oil supply structure of this kind refrigeration compressor; Post the helical spring that rises around the fuel sucking pipe spiral inner wall in the fuel sucking pipe; During the fuel sucking pipe rotation, helical spring is rotation synchronously also, because mandrel is fixed; Between fuel sucking pipe and mandrel, form spiralling oil supply gallery, be easy to arrive main shaft top through the centrifugal force refrigeration oil.For slow-speed of revolution compressor or the less thin bent axle compressor of main shaft diameter, can be easy to realize carrying oil, reduced the wearing and tearing of friction pair between each part, reduce the complete machine power loss, improve compressor working life.

Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
In conjunction with Fig. 1 to Fig. 3, the novel oil supply structure of refrigeration compressor comprises bent axle and fuel sucking pipe 1; The bottom of bent axle is a main shaft 2; The endoporus interference of main shaft 2 is equipped with fuel sucking pipe 1, posts the helical spring 3 that rises around fuel sucking pipe 1 spiral inner wall in the said fuel sucking pipe 1, and standing in the fuel sucking pipe 1 has mandrel 4.The cross section of helical spring 3 spring threads is a rectangular, helical spring 3 spiral rising sense of rotation and fuel sucking pipe 1 direction of rotation, and mandrel 4 is fixing by the steel wire that passes mandrel 4 bottoms 5.
In conjunction with Fig. 1, Fig. 2, Fig. 4, the novel oil supply structure of refrigeration compressor comprises bent axle and fuel sucking pipe 1; The bottom of bent axle is a main shaft 2; The endoporus interference of main shaft 2 is equipped with fuel sucking pipe 1, posts the helical spring 3 that rises around fuel sucking pipe 1 spiral inner wall in the said fuel sucking pipe 1, and standing in the fuel sucking pipe 1 has mandrel 4.The cross section of helical spring 3 spring threads is circular, helical spring 3 spiral rising sense of rotation and fuel sucking pipe 1 direction of rotation, and mandrel 4 is fixing by the steel wire that passes mandrel 4 bottoms 5.
The novel oil supply structure of this kind refrigeration compressor; Post the helical spring that rises around the fuel sucking pipe spiral inner wall in the fuel sucking pipe; During the fuel sucking pipe rotation, helical spring is rotation synchronously also, because mandrel is fixed; Between fuel sucking pipe and mandrel, form spiralling oil supply gallery, be easy to arrive main shaft top through the centrifugal force refrigeration oil.For slow-speed of revolution compressor or the less thin bent axle compressor of main shaft diameter, can be easy to realize carrying oil, reduced the wearing and tearing of friction pair between each part, reduce the complete machine power loss, improve compressor working life.
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technician in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
