Abstract
The utility model discloses a refrigeration compressor with a novel crankshaft oil groove structure. The refrigeration compressor comprises a crankshaft; a main shaft is arranged at the lower part of the crankshaft; an eccentric shaft is arranged at the upper part of the crankshaft; a main shaft helical oil groove is arranged on the outer wall of the main shaft; and a main shaft oil outlet is arranged on the main shaft helical oil groove. A section of main shaft oil storage tank which is used for storing oil is arranged under the main shaft oil outlet along the extension direction of the main shaft helical oil groove; an eccentric shaft helical oil groove is arranged on the outer wall of the eccentric shaft; an eccentric shaft oil outlet is arranged on the eccentric shaft helical oil groove; and a section of eccentric shaft oil storage tank which is used for storing oil is arranged under the eccentric shaft oil outlet along the extension direction of the eccentric shaft helical oil groove. The refrigeration compressor has the beneficial effects that the crankshaft oil groove structure is simple in technology and has obvious lubrication action on the friction pair of the crankshaft when the compressor is started up, the power consumption can be effectively reduced when the compressor is started up, and the energy efficiency level of the compressor is increased.
Description
Technical field
The utility model relates to refrigeration compressor, is specifically related to the crankshaft of cooler compressor tank structure.
Background technique
Crankshaft structure as shown in Figure 1, that hermetically sealed compressor is common comprises: main shaft 1, eccentric shaft 2, counter weight 3, main shaft oil groove 4, eccentric shaft oil groove 5.As shown in Figure 2, bent axle friction pair distributed architecture, the main shaft bottom is provided with friction pair 6, eccentric shaft is provided with friction pair 7.Hermetically sealed compressor is when deciding the rotating speed operation, and refrigeration oil has sufficient lubrication to each friction pair of moving element under the effect of crankshaft oil pump, and the friction pair power loss is little.When totally-enclosed compressor was out of service, respectively the rub refrigeration oil of vice division chief of moving element was back in the compressor oil sump, and when starting once more, it is lubricated that each friction pair of moving element does not have refrigeration oil, and each friction pair frictional work loss is bigger, influences the working life of compressor.
The model utility content
The purpose of the utility model is to provide a kind of refrigeration compressor with new type crank tank structure, has novel structure, the advantage that using effect is good.
The utility model to achieve these goals, the technical solution of employing is:
Have the refrigeration compressor of new type crank tank structure, comprise bent axle, the bottom of bent axle is a main shaft, and the top of bent axle is eccentric shaft, and spindle outer wall has the main shaft helical oil groove, and the main shaft oil outlet is arranged on the main shaft helical oil groove; Said main shaft oil outlet below has one section main shaft oil storage tank that is used for oil storage according to main shaft helical oil groove bearing of trend.
Further, said eccentric shaft outer wall has the eccentric shaft helical oil groove, and the eccentric shaft oil outlet is arranged on the eccentric shaft helical oil groove, and said eccentric shaft oil outlet below has one section eccentric shaft oil storage tank that is used for oil storage according to eccentric shaft helical oil groove bearing of trend.
The beneficial effect of the utility model:
This kind bent axle tank structure technology is simple, and the bent axle friction lubricating effect when starting shooting to improving compressor is obvious, the power loss in the time of effectively reducing the compressor start, the efficiency level of raising compressor.
Below the main shaft oil outlet, have one section main shaft oil storage tank that is used for oil storage, below the eccentric shaft oil outlet, have one section eccentric shaft oil storage tank that is used for oil storage according to eccentric shaft helical oil groove bearing of trend according to main shaft helical oil groove bearing of trend.When compressor is out of service; Respectively the rub refrigeration oil part of vice division chief of moving element is back in the compressor oil sump; At main shaft oil storage tank and some refrigeration oil of eccentric shaft oil storage tank internal memory, when starting once more, each friction pair of moving element at first utilizes the refrigeration oil in main shaft oil storage tank and the eccentric shaft oil storage tank to provide lubricated for each friction pair; Reduce each friction pair frictional work loss, prolonged the working life of compressor.
Description of drawings
Fig. 1 is the common crankshaft structure figure of existing technology hermetically sealed compressor.
Fig. 2 is existing technology bent axle friction pair distributed architecture figure.
Fig. 3 is new type crank tank structure figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
In conjunction with Fig. 3; Have the refrigeration compressor of new type crank tank structure, comprise bent axle, the bottom of bent axle is a main shaft 1; The top of bent axle is eccentric shaft 2; Main shaft 1 outer wall has main shaft helical oil groove 3, and main shaft oil outlet 4 is arranged on the main shaft helical oil groove 3, and said main shaft oil outlet 4 belows have one section main shaft oil storage tank 5 that is used for oil storage according to main shaft helical oil groove 3 bearing of trends.Said eccentric shaft 2 outer walls have eccentric shaft helical oil groove 6, and eccentric shaft oil outlet 7 is arranged on the eccentric shaft helical oil groove 6, and said eccentric shaft oil outlet 7 belows have one section eccentric shaft oil storage tank 8 that is used for oil storage according to eccentric shaft helical oil groove 6 bearing of trends.
Below the main shaft oil outlet, have one section main shaft oil storage tank that is used for oil storage, below the eccentric shaft oil outlet, have one section eccentric shaft oil storage tank that is used for oil storage according to eccentric shaft helical oil groove bearing of trend according to main shaft helical oil groove bearing of trend.When compressor is out of service; Respectively the rub refrigeration oil part of vice division chief of moving element is back in the compressor oil sump; At main shaft oil storage tank and some refrigeration oil of eccentric shaft oil storage tank internal memory, when starting once more, each friction pair of moving element at first utilizes the refrigeration oil in main shaft oil storage tank and the eccentric shaft oil storage tank to provide lubricated for each friction pair; Reduce each friction pair frictional work loss, prolonged the working life of compressor.
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.
