Piston chamber, the end of the side of the separate bearing hole 11 of air cylinder structure 12 is set as column structure, column structure structure it is outer
At least part of molded line of circumferential surface is arc.Setting, which can be avoided, in this way is arranged rectangular mode for the end of air cylinder structure and causes
The case where cylinder block consumptive material increases.Using the cylinder block of the structure, the production cost of cylinder block can be effectively reduced.Column knot
The exhaust passage 14 being connected with piston chamber is offered on the end face of structure.
Further, flanged structure 13, the outer surface of flanged structure 13 and shown column structure are also set up on cylinder block 10
It is connected, exhaust passage 14 is opened on flanged structure 13 and/or column structure.Setting, which can enhance to add, in this way is equipped with exhaust
Wall thickness at channel 14 improves the reliability of the cylinder block.It certainly, in the present embodiment, can also be directly by column structure
The molded line of outer peripheral surface be arranged to circular configuration.
Preferably, the aperture of exhaust passage 14 isWherein,
As shown in Figures 4 to 6, cylinder block 10 is additionally provided with stabilizer blade 30, stabilizer blade 30 be it is multiple, under air cylinder structure 12
Chip space 40 is provided between adjacent two stabilizer blade 30 of side.Chip space 40 is wedge structure, is used for cylinder head bolt hole part
Chip removal when processing can prevent clast when processing from clearing up unclean and entering inside compressor, part card cylinder is caused to cause pressure
Contracting machine integrity problem.
Compressor further includes crankshaft 50.Crankshaft 50 is arranged in bearing hole 11, and the main shaft 51 of crankshaft 50 is hollow column
Structure, the hollow structure of main shaft 51 form oil supply gallery, and oil supply gallery is extended along the axis direction of main shaft 51, main shaft 51
The wall thickness of radial direction is L, wherein 0.5mm≤L≤1.5mm.Setting can efficiently reduce the use material of crankshaft in this way, have
The weight for reducing to effect crankshaft, then effectively alleviates the main screw lift of compressor.
In order to further play the role of reducing compressor main screw lift, crankshaft 50 further includes crank-pin 52, crank-pin
52 are arranged with being connected and misplace with main shaft 51, and the middle part of crank-pin 52 is also provided with into hollow structure.
Compressor in above-described embodiment can be also used for technical field of refrigeration equipment, i.e., according to the present utility model another
Aspect, provides a kind of refrigerating plant, including compressor, and compressor is the compressor in above-described embodiment.Wherein, which fills
It sets and can be refrigerator.
Specifically, in the cylinder block of bearing hole setting oil guide groove, which reduces crankshaft due to being arranged on cylinder block
On open up oil circuit, therefore the wall thickness of crankshaft can do thinner, be conducive to the weight for mitigating crankshaft, reduce cost.Crankshaft outer wall
Thinner, quality mitigates, therefore rotating inertia force reduces, and the frictional dissipation of crankshaft and bearing reduces, and is transmitted to outside compressor
Vibration reduces.After crankshaft outer surface eliminates oil guide groove, crankshaft centreless grinding processing excircles Quality advance reduces Crankshaft Machining
Fraction defective.Wherein, oil guide groove spiral number of turns can be -4 circle of 0.5 circle.
Using the compressor of the structure, which has small in size, light-weight piston compressor cylinder block, cylinder block
Oil guide groove is arranged in bearing hole center, and Oil Guide slot cross-section is round, rectangle or trapezoidal, and traditional structure is then removed in the outer surface of crankshaft
Oil guide groove, which can do crankshaft outer wall thinner, therefore quality is lighter, advantageously reduces the rotatory inertia of crankshaft
Power reduces the friction loss of part, simultaneously because rotary inertia reduces, vibration also can be reduced accordingly.
In the present embodiment, there are three stabilizer blade, cylinder head part two, tail portions one for cylinder block.Wherein it is possible to being located at gas
Stator bolts chip space 16 (as shown in Figure 6) is arranged in the end of the separate stator side of stabilizer blade at cylinder head.Cylinder block end
Including cylinder head and bearing block, cylinder head is generally round, be conducive to mitigate part weight, bearing block be it is rectangular, be conducive to above
It is disposed to the bolt hole of fastening valve plate and suction and discharge valve block (not shown) and cylinder head.There is a side in round cylinder head side
Shape table top, arranges internal diameter aboveExhaust passage.
As shown in figure 5, there are three oil leaking holes around bearing block, it is ensured that lubricating oil when compressor is run at the top of crankshaft
Oil sump can be returned in time, guarantee there are enough oil masses when oil pump oils.
As shown in fig. 7, crank spindle and countershaft wall thickness are thinner since oil guide groove is arranged on cylinder block bearing hole,
Axle center is entirely hollow structure, and quality is lighter, reduces crankshaft rotating inertia force, and frictional dissipation and vibration can all become smaller, favorably
In the noise of the performance and reduction compressor that promote compressor.Using the crankshaft of such oil circuit, wall thickness can be set to 0.5mm-
1.5mm, weight are greatly reduced compared to traditional structure.
Than that described above, it is also necessary to which explanation is " one embodiment " spoken of in the present specification, " another implementation
Example ", " embodiment " etc. refer to that specific features, structure or the feature of embodiment description is combined to be included in the application summary
