Abstract

The invention discloses a linear compressor scroll plate spring axial stiffness testing device and a manufacturing method thereof. The testing device is formed by an upper cover, a base, a pull rod, an outer washer, an inner washer, a pressing nut, an outer gasket and an inner gasket. The inner edge and the outer edge of a scroll plate spring are respectively fixed through the testing device of the invention, thus the stress directions of the inner edge and the outer edge are strict axial directions and are parallel to each other in a reverse way, the stress bias and bending deformation generated in a scroll plate spring axial stiffness test is eliminated to the maximum so as to accurately measure the displacement of the plate spring under axial stress and the corresponding intensity value and changing trend, the comparison and reference of accurate measured data are provided for the design and manufacture of the scroll plate spring, and the device has positive effect for the optimal design of the scroll plate spring and the development of a linear compressor.

Description

technical field [0001] The invention relates to a linear compressor and its plate spring, in particular to a testing device and a manufacturing method for the axial stiffness of a scroll plate spring of a linear compressor. Background technique [0002] Linear compressor, or linear compressor, is an innovative reciprocating piston compressor. It uses a linear motor to drive the piston to make a reciprocating linear motion in the cylinder, which theoretically completely eliminates the radial force on the piston, thus eliminating the mechanical wear between the piston and the cylinder wall and the resulting useless work, working life and The energy conversion efficiency has been greatly improved, so it has very important applications in special fields such as aviation, aerospace, and military that require long life, high reliability, and high efficiency. For example, most of the two most widely used long-life regenerative cryogenic refrigerators in the aerospace field—pulse t...
