Plate spring, plate spring set and compressor

Abstract

The invention discloses a plate spring, a plate spring set and a compressor, wherein the plate spring comprises two elastic arms and a fixing device used for installation and positioning; the structures of the two elastic arms are same and are formed by tangency of a plurality of concentric circular arcs or eccentric circular arcs; the radii of the plurality of concentric circular arcs or eccentric circular arcs increase from inside to outside gradually, and all the concentric circular arcs or eccentric circular arcs are located on the same straight line; the initial ends of the two elastic arms are tagent, and an inner fixing hole is formed in the connection position of the two elastic arms which are uniformly distributed taking the inner fixing hole as the center; the tail ends of the two elastic arms are connected with fixing device respectively. The plate spring has smaller equivalent mass and higher inherent frequency and rigidity. The plate spring set comprises a plurality of plate springs, and the rigidity among relative moving parts can be improved. According to the compressor, the plate spring set is adopted, so that the rigidity among the relative moving parts is improved, the weight is light, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of springs, in particular to a leaf spring, a leaf spring set composed of a plurality of leaf springs and a compressor including the leaf spring set. Background technique [0002] Plate spring support technology is one of the key technologies of linear compressors. Compared with the traditional cylindrical spring, the leaf spring has a larger radial stiffness, so that the piston will not produce radial displacement due to vibration during movement, avoiding direct contact between the piston and the cylinder; and the axial stiffness of the leaf spring Far smaller than its radial stiffness, the piston can freely reciprocate in the cylinder. [0003] The patent No. CN101892971A discloses a linear compressor using two different types of linear leaf spring support systems. The equivalent mass of the leaf spring is too large to meet the high frequency and low equivalent mass requirements of the linear compressor....

AI Technical Summary

Problems solved by technology

[0003] The patent No. CN101892971A discloses a linear compressor using two different types of linear leaf spring support systems. The equivalent mass of the leaf spring is too large to meet the high frequency and low equivalent mass requirements of the linear compressor.

The patent No. JP2003247580 (A) discloses a scroll arm leaf spring, and the patent No. CN201010248988.5 discloses a linear arm leaf spring and a scroll arm leaf spring. These two patents disclose The vortex arm leaf springs have the following problems: the equivalent mass of the leaf spring is too large, in order to meet the stiffness and natural frequency requirements, the mass of the parts will be increased

[0004] Therefore, the traditional leaf spring is difficult to meet the requirements of low equivalent mass, high stiffness and high frequency due to its own structural limitations.
