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.

Embodiment 1

[0051] Example 1, see Figure 4 ;

[0052] The plate spring in this embodiment is a plate spring 300 with equal width and multiple circular arms. The equal-width multi-circular-arm leaf spring 300 in this embodiment includes two axially symmetrical elastic arms 310 and 320, and a circular fixing ring 330. The fixing ring 330 is provided with an outer fixing hole 331, which is used for corresponding installation The structure is fixed.

[0053] The structures of the two elastic arms 310 and 320 are the same, and the widths from the starting end to the end are constant, that is, the width is unchanged, and they are both formed by tangent to three pairs of concentric arcs or eccentric arcs. The 3 pairs of concentric arcs or eccentric arcs gradually increase in radius from the inside to the outside, and their centers are all on the same straight line. The initial ends of the two elastic arms 310 and 320 are tangent, and an inner fixing hole 340 is provided at the connection bet...

Embodiment 2

[0055] Example 2, see Figure 5 ;

[0056] The leaf spring in this embodiment is a leaf spring 400 with unequal width and multiple circular arms. The unequal width multi-circular arm plate spring 400 in this embodiment includes two axially symmetrical elastic arms 410 and 420, and a circular fixing ring 430. The fixing ring 430 is provided with an outer fixing hole 431 for corresponding The installation structure is fixed.

[0057] The two elastic arms 410 and 420 have the same structure, and gradually widen from the center to the outside (from the start end to the end end), and are formed by three pairs of concentric arcs or eccentric arcs tangent. The 3 pairs of concentric arcs or eccentric arcs gradually increase in radius from the inside to the outside, and their centers are all on the same straight line. The initial ends of the two elastic arms 410 and 420 are tangent, and an inner fixing hole 440 is provided at the connection between the initial ends. The two elastic ...

Abstract

The invention discloses a leaf spring, a leaf spring group and a compressor, wherein the leaf spring includes two elastic arms and a fixing device for installation and positioning; The eccentric arcs are tangent; several pairs of concentric arcs or eccentric arcs gradually increase in radius from inside to outside, and the centers of all concentric arcs or eccentric arcs are on the same straight line; the initial ends of the two elastic arms Tangentially, an inner fixing hole is arranged at the joint, and the two elastic arms are uniformly distributed around the inner fixing hole; the ends of the two elastic arms are respectively connected to the fixing device. The leaf spring of the present invention has smaller equivalent mass, higher natural frequency and stiffness. The leaf spring set provided by the present invention includes a plurality of the above-mentioned leaf springs, which can improve the rigidity between relative moving parts. The compressor provided by the invention adopts the plate spring group of the invention, which improves the rigidity between relative moving parts, has light weight and long service life.

Description

technical field [0001] The present invention relates to the technical field of springs, and in particular, to a leaf spring set composed of a leaf spring and a plurality of leaf springs, and a compressor including the leaf spring set. Background technique [0002] Leaf 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 have radial displacement due to vibration during movement, avoiding direct contact between the piston and the cylinder; and the axial stiffness of the leaf spring Much smaller than its radial stiffness, it allows the piston to reciprocate freely in the cylinder. [0003] Patent No. CN101892971A discloses a linear compressor using two different types of plate spring support systems, the equivalent mass of the plate spring is too large, and it is difficult to meet the requirements of high frequency and low equ...
