Abstract

The invention discloses a linear compressor with a linear arm plate spring. Due to the low radial stiffness of the plate spring in the existing linear compressor, the position of the compressor piston is prone to radial displacement, resulting in a decrease in compressor efficiency. The invention includes a compressor assembly, a magnetic field assembly, an AC motor assembly, and a plate spring assembly; the compressor assembly includes a box body, a frame and a cylinder; the magnetic field assembly includes a permanent magnet and a yoke; the AC motor assembly includes an AC coil and a support frame; The spring assembly includes a leaf spring base and a leaf spring group. The leaf spring group includes 2 to 5 pieces of linear leaf springs. The adjacent linear leaf springs are separated by washers. There are elastic beams between the through holes. The invention adopts a simple linear arm plate spring structure, the mass of the spring is reduced, the elastic coefficient is unchanged, the resonant frequency of the spring and the system is increased, the compressor works at a higher frequency, and the efficiency of the compressor is improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, and relates to a moving coil linear compressor, in particular to a linear arm plate spring linear compressor. Background technique [0002] Linear compressors in cryogenic engineering provide dynamic pressure waves to cryocoolers that power the entire refrigeration cycle. It mainly uses a linear motor to drive the piston to make a reciprocating linear motion in the cylinder. According to the theory of electromagnetic field, the linear motor exerts a linear force on the piston that is absolutely parallel to the axial direction of the piston. Therefore, in theory, a correctly designed linear compressor is completely Radial forces on the piston are eliminated. Therefore, linear compressors have very important applications in special fields such as aerospace and military that require long life, high reliability and high efficiency. The leaf spring in the existing linear compressor adopts the sc...
