LEAF SPRING, LEAF SPRING GROUP, AND COMPRESSOR

摘要

A leaf spring (100) comprises at least two spring arms (120, 130) and an inner fixing hole (110). The at least two spring arms (120, 130) are evenly distributed around the inner fixing hole (110); each spring arm is of the same structure, and an outer fixing hole (122) is disposed at the outermost end of each spring arm. Further provided are a leaf spring group and a compressor. The leaf spring group comprises multiple leaf springs, and the compressor comprises the leaf spring group. The provided leaf spring uses a structure of multiple concentric circular arms and a structure of concentric vortex arms, and the two structures have small equivalent mass, so that the rigidity and inherent frequency requirements can be met without the need of increasing the mass of the components, thereby reducing the product mass and saving the cost.
