Description

The spring cupport structure of reciprocal compressor
Technical field
What the present invention relates to is reciprocal compressor, particularly be the spring cupport structure of reciprocal compressor.
Background technique
Generally speaking, the compressor with freezing cycle device is after the refrigerant gas of the low-temp low-pressure state that flows into from rapid steamer is compressed, with the machine of high-temperature high-pressure state discharge.
Above-mentioned compressor is divided into kinds such as rotary compressor, reciprocal compressor, scroll compressor according to the mode of compressed fluid, reciprocal compressor be piston with the line style move mode, suck pressurized gas.Reciprocal compressor can be divided into again: rotatablely moving of drive motor converted to moving back and forth of piston and suck the mode of pressurized gas and the drive motor straight reciprocating motion makes reciprocating motion of the pistons and sucks the mode of pressurized gas.
As shown in Figure 1, the structure of existing reciprocal compressor includes: bottom a certain amount of lubricant oil of packing into is communicated with the container 10 of the sealing that gas suction pipe SP and gas outlet pipe DP are set; The rack section 20 that container 10 inner elastomeric are provided with; Be fixed on the rack section 20, and make mover 33 do the reciprocating electric 30 of straight reciprocating motion; Be combined on the mover 33 of reciprocating electric 30, and the compression member 40 of using rack section 20 to support; The mover 33 of reciprocating electric 30 by the moving direction elastic support and induce the resonant spring parts 50 of resonance motion; Be assemblied on the rack section 20 also being enclosed in the lubricant oil supply department 60 of the lubricant oil of container 10 inside to the slide part supplying lubricating oil of compression member 40.
Above-mentioned rack section 20 comprises: the preceding square bearer 21 that supports compression member 40; Before being combined on the square bearer 21 and support the central frame 22 of reciprocating electric 30; Be combined in central frame 22 and support the back square bearer 23 of reciprocating electric 30.
Above-mentioned reciprocating electric 30 comprises: be arranged on the outer stator 31 between central frame 22 and the back square bearer 23; Form certain intervals with outer stator 31 and combine, insert the inside stator 32 that is combined in back square bearer 23; Be arranged between outer stator 31 and the inside stator 32, but and the mover 33 of straight reciprocating motion.
Above-mentioned compression member 40 comprises: integrally formed cylinder 41 on the framework 21 forwardly; Be combined on the mover 33 of reciprocating electric 30, and the piston 42 that in the compression volume P of cylinder 41, moves back and forth; The inhaling valve 43 that the restriction refrigerant gas sucks when being assemblied in the front end of piston 42 and opening and closing the suction passage F of its piston 42; The exhaust valve assembly 44 that limit compression gas is discharged when being contained in the discharge side of cylinder 41 and opening and closing compression volume P.
Above-mentioned resonant spring parts 50 comprise: the spring support platform 51 that is combined in mover 33 and piston 42 connection parts; With spring support platform 51 is center and at least more than one the 1st group of spring 52 that supports its front side; The 2nd group of spring 53 of at least more than one of side, supported spring support platform 51 back; On spring support platform 51, have block the 1st group of spring 52 and the 2nd group of spring 53 and can fix with the outstanding protuberance 54 of certain altitude.
Lubricant oil supply department 60 comprises: be assemblied in the underpart of rack section 20, and the lubricant oil that draws container 10 lubricant oil in its rack section 20 vibrations processes draws portion (not shown); In order to be communicated with outlet side and the compression member 40 that lubricant oil draws portion (not shown), and the lubricant oil service duct 62 that forms at rack section 20.
Below the start-up course of above-mentioned existing reciprocal compressor is carried out following explanation:.
Reciprocating electric 30 to reciprocal compressor applies power supply, form the magnetic line of force between outer stator 31 and the inside stator 32, the mover 33 in space is when magnetic line of force direction is moved between its outer stator 31 and inside stator 32, continue to-and-fro motion by resonant spring parts 50, meanwhile, piston 42 changes the volume of compression volume P in cylinder 41 reciprocates inside after, implement repeatedly refrigerant gas is sucked the process that discharge the compression back to compression volume.
But, the defective that resonant spring parts 50 spring support platforms 51 exist as shown in Figure 2 in the above-mentioned existing reciprocal compressor, promptly, make spring support platform 51 with ferrous materials and utilize processing method making such as sheet metal, certain altitude is outstanding and when supporting the protuberance 54 of the 1st group of spring 52 and the 2nd group of spring 53 on fabrication and processing spring support platform 51 bottoms, contact the part that intersects with protuberance 54 in the bottom of spring support platform 51 and can not form the right angle, and that formation is circular arc 54a, therefore, the 1st group of spring 52 and the 2nd group of spring 53 its terminal parts can not contact with protuberance 54 well, cause the spring support platform 51 after the assembling because friction causes wearing and tearing and noise.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, the spring support platform and two groups of fine combinations of spring that provide a kind of support piston to resonate reciprocating the 1st group of spring and the 2nd group of spring, the spring cupport structure of the reciprocal compressor of reduction wearing and tearing and noise.
Solving the problems of the technologies described above the technological scheme that is adopted is: a kind of spring cupport structure of reciprocal compressor, and this spring cupport structure includes: be combined in the spring support platform on reciprocating electric mover and the piston connection part; With the spring support platform is center and at least more than one the 1st group of spring that supports the one side; The 2nd group of spring of at least more than one of supported spring support platform opposite side; The spring support platform includes protuberance, and this protuberance is one to have respectively on bi-side and can fill in the protuberance of fixing the 1st group of spring and the outstanding certain altitude of the 2nd group of spring; Form the right angle that has groove in spring support platform bottom and protuberance jointing place.
The invention has the beneficial effects as follows: because protuberance that forms on the spring support platform of the present invention and jointing place, spring support platform bottom form the right angle, and at the groove of spring support platform bottom side formation with the certain width and the degree of depth, make the 1st group of spring and the 2nd group of spring be close to the support platform bottom, assembling rear spring support platform can reduce vibrations and noise that friction causes significantly.In addition, support the spring support platform aluminium material of the 1st group of spring and the 2nd group of spring, not only weight reduction also reduces the noise that vibrations bring simultaneously.Spring support platform of the present invention can utilize the manufacturing of aluminium material casting technique, makes not form circle on its edge part and form the right angle to hold very much and accomplish.
