Abstract
The utility model discloses a bent axle for compressor, including centrifugal pump and wesco pump, the centrifugal pump includes the oil pocket and inhales oil pipe or eccentric oil pocket, be equipped with the oil groove on the surface of wesco pump, the starting point and the terminal point of oil groove are equipped with down oilhole and last oilhole respectively, the non - machining region's at bent axle middle part diameter is less than the machining region's of its upper and lower both sides diameter, forms the oil storage space, be equipped with the benefit oil groove on the bent axle, mend open position in the non - machining region of oil groove, mend oil groove along machining region downwardly extending. The utility model discloses a carry out redesign to the oil circuit of bent axle, easy bruised place increases the partial lubrication to the bent axle, makes the oil circuit structure more reasonable, the position that the bent axle that makes the compressor is in abominable surrounding environment can obtain enough oil mass supplies, has guaranteed the lubrication between the pair, and that has reduced that near oilhole position leads to because of the partial lubrication is insufficient under the bent axle draws trouble such as hair, has promoted the compressor reliability.
Description
Technical field
This utility model relates to refrigerant compression technical field, a kind of bent axle for refrigeration compressor.
Background technology
Refrigeration compressor is generally disposed at the bottom rear of refrigerator, and its effect is the circulating refrigerant in compression, conveying refrigerator system, thus is transferred to surrounding from refrigerator inside by heat.When freezer compressor runs, by motor driven crankshafts bar linkage motion mechanism, then drive piston cylinder units that cold-producing medium is compressed.Bent axle is a vitals in the crankshaft link rod motion mechanism of compressor, and it has pump functional oil, and on the one hand Castor Oil bent axle-connecting rod-piston motion, prevents motion stuck；On the other hand piston-cylinder unit can be cooled down.At present, returning in fault type relating to of compressor, bent axle plucking fault is present in around the lower oilhole position of a week more.Through analyzing fault discovery, under bent axle, oil-hole location coordinates with the lower end revolute pair of crankshaft hole, bears the moment loading produced when compressing from piston-cylinder unit herein and (during piston compression cold-producing medium, by connecting rod, power is transferred to bent axle.Due to the support between bent axle and crankcase, form moment and pass to the bent axle near lower oilhole), operating mode is relatively severe, and lower oilhole opposite side easily causes bent axle plucking fault because lubrication is insufficient.
Summary of the invention
Technical problem to be solved in the utility model is that proposing one can increase refrigeration oil supply, it is to avoid the insufficient bent axle for refrigeration compressor causing the faults such as plucking of bent axle partial lubrication.
For solving above-mentioned technical problem, a kind of bent axle for refrigeration compressor of this utility model includes that centrifugal pump and Wesco pump, described centrifugal pump include oil pocket and fuel sucking pipe or eccentric oil pocket；The outer surface of described Wesco pump is provided with oil groove, and the beginning and end of described oil groove is respectively equipped with lower oilhole and upper oil hole；The diameter of the non-machining area in the middle part of described bent axle, less than the diameter of the machining area of its upper and lower both sides, forms oil storage space；Described bent axle is provided with repairing groove, and the opening of described repairing groove is positioned at described non-machining area, and described repairing groove downwardly extends along machining area.
Above-mentioned a kind of bent axle for refrigeration compressor, the lower end of described repairing groove is positioned on described bent axle, the right opposite side of described lower oilhole.
Above-mentioned a kind of bent axle for refrigeration compressor, described repairing groove extends downward the horizontal level beyond described lower oilhole.
Above-mentioned a kind of bent axle for refrigeration compressor, the diameter less than the diameter of described machining area 1～2mm of described non-machining area.
Above-mentioned a kind of bent axle for refrigeration compressor, described oil groove is helicla flute.
This utility model is owing to have employed above-mentioned technical pattern, it is by redesigning the oil circuit of bent axle, partial lubrication is strengthened for bent axle region easy to wear, make oil channel structures more reasonable, the bent axle making compressor is in the position of severe surrounding can obtain enough oil mass supplies, ensure that the lubrication between kinematic pair, decrease the faults such as the plucking that under bent axle, near oilhole, position causes because partial lubrication is insufficient, improve compressor reliability.Meanwhile, the oil mass that repairing groove can supplement also limited by oil storage space, it is to avoid valve block liquid hammer that bent axle causes because pump oil mass is excessive, the problem such as noise is big, performance is low.

Detailed description of the invention
As shown in Figure 1, the refrigeration compressor using this utility model bent axle includes an airtight shell 01, piston-cylinder unit 02, bent axle-linkage 03 and electric motor units 04, suction nozzle 11 and exhaustor 12 it is provided with on shell 01, cold-producing medium enters piston-cylinder unit 02 through suction nozzle 11, electric motor units 04 drives bent axle-linkage 03, drive piston-cylinder unit 02 to move reciprocatingly thus compress cold-producing medium, discharge compressor housing 01 through exhaustor 12.
As in figure 2 it is shown, this utility model bent axle 05 is assembled together with crankcase 06.Please refer to shown in Fig. 3, bent axle 05 includes centrifugal pump 07 and Wesco pump 08, and centrifugal pump 07 includes fuel sucking pipe 71 and oil pocket 72, uses the press mode of routine to assemble between fuel sucking pipe 71 and oil pocket 72, utilize centrifugal action, refrigeration oil 13 is delivered up (please refer to shown in Fig. 1.Wherein fuel sucking pipe 71 may be used without the eccentric oil pocket of at present the most ripe application and replaces)).
As shown in Figure 3 and Figure 4, the outer surface of Wesco pump 08 is provided with helical oil groove 82(and uses the spiral fluted effect that oils preferable, spiral and the viscosity of oil can be utilized, oil is delivered up), starting point (bottom) and terminal (top) position of this helical oil groove 82 are respectively equipped with lower oilhole 81 and upper oil hole 83.The diameter of the non-machining area 51 in the middle part of bent axle 05, less than the diameter (both diameter difference away from can be 1～2mm) of the machining area 50,52 of its upper and lower both sides, makes non-machining area 51 form oil storage space 65(please refer to shown in Fig. 2 with crankcase 06).
As shown in Figure 5 and Figure 6, repairing groove 09 it is additionally provided with on bent axle 05, repairing groove 09 is positioned at the right opposite side of lower oilhole 81, the opening 92(of repairing groove 09 i.e. its upper end) communicate with non-machining area 51, the cell body of repairing groove 09 downwardly extends along machining area 50, the cross sectional shape of repairing groove 09, extension track do not limit, and its bottom 93 is positioned at the position of the bottom level position or more lower of lower oilhole 81.
