Description
Technical field
This patent relates to linear compressor and laminated spring thereof, particularly a kind of proving installation of linear compressor spiral laminated spring axial rigidity and manufacture method.
Background technology
Linear compressor, or claim Linearkompressor, be a kind of reciprocating-piston compressor with innovation meaning.It utilizes linear electric motors driven plunger to do reciprocating linear motion in the cylinder, completely eliminate the radial forces to piston in theory, thus the mechanical wear between piston and cylinder wall and consequent idle work is also eliminated, mission life and energy conversion efficiency all increase substantially, so needing the long-life, the special dimension such as Aeronautics and Astronautics, military affairs that is highly reliable and efficiency operation has very important application.Such as, two class long-life regenerating type low-temperature refrigerator---pulse tube refrigerating machine and the sterlin refrigerators that current aerospace field is most widely used, the overwhelming majority adopts linear compressor as its power source.
The linear compressor being applied to the fields such as Aero-Space in the world mainly adopts Oxford type version.So-called " Oxford type ", it is gained the name and comes from two important technology inventions of Regius professor---and clearance seal and laminated spring support, these two technology are critical support that linear compressor realizes oil-free lubricatoin and the running of energy long-life.
Gap sealed essence makes to remain between the piston of motion and cylinder inner wall small gap (be called air gap, thickness is micron dimension).Gap Sealing Technology instead of the sealed solid of contact in contactless gas motive seal mode, thus the ingenious and contact wear that solves up hill and dale between piston and cylinder and the oil lubrication needed for Conventional solid sealing bring pollution problem, the influence on development for oil-free lubricatoin formula long-life linear compressor is far-reaching.
The Main Function of laminated spring support technology is realization and the clearance seal needed for long term maintenance.Laminated spring is generally made up of one group or the thin spring leaf of array, and it is very large that these spring leafs are designed to rigidity diametrically, and rigidity is less in the axial direction.Piston axle is fixed in the center of laminated spring, ensures that piston moves vertically all the time in cylinder, and do not offset diametrically with this, thus the air gap thickness between strict guarantee piston and cylinder inner wall.
From above-mentioned discussion, laminated spring plays the key effect of core in linear compressor technology, the quality of laminated spring design and manufaction quality will directly have influence on gap sealed effect, thus all produces conclusive impact to the efficiency of linear compressor, reliability and mission life.
In practice, spiral laminated spring is the laminated spring type that linear compressor is commonly used the most, and it is made up of several spiral arms, is divided into the key positions such as spiral groove, outer rim, inner edge, center pit and outer rim fixed orifice.Designing and developing of spiral laminated spring needs through complicated calculating and utilizes the method for modeling analysis to make structure be optimized, to obtain required key parameter values as far as possible.Before input practicality, also need to carry out detailed check analysis and test to the sample designed and machine, contrast design calculates and model analysis, finds out material and processing technology aspect possibility Problems existing, and obtains the feedback information structurally optimized further.At this wherein, the measurement of axial rigidity and radial rigidity is two very crucial tests.
First the test of spiral laminated spring axial rigidity requires inner edge and the outer rim of fixed head spring respectively, and keep the center line of proving installation and the verticality of laminated spring plane high-precision, the power suffered by such guarantee laminated spring is axial force.In test process, more want strict guarantee proving installation be applied to power in spiral laminated spring inner edge and outer rim all with the plane orthogonal of laminated spring, laminated spring inner edge is reverse parallel with the power suffered by outer rim, in the depth of parallelism, have certain deviation if there is the two, then test value will there will be comparatively big error.Above-mentioned two requirements propose very strict requirement to laminated spring axial rigidity proving installation.Because the development at home of long-life Oxford type linear compressor is also in the starting stage, so also rare for the Special testing device of its spiral laminated spring axial rigidity.
