Embodiment 1

[0041] A sector spring arm such as figure 1 As shown, the fan-shaped spring arm 1 is composed of a first fan-shaped arm 12, a second fan-shaped arm 14 and a transition arc 13 connecting the two. The two ends of the fan-shaped spring arm are provided with a first mounting hole 11 and a second mounting hole 15. The area with mounting holes is a fixed area, and an included angle of 10 to 70 degrees is provided between the fixed area and its adjacent fan-shaped arm (as in this embodiment, the angle of the included angle is 70 degrees), and the fixed area The length is greater than the transverse width of the fan-shaped arm, so that the stress on the fixed end can be reduced during installation.

[0042] A sector spring consisting of the sector spring arms described above, such as figure 2 As shown, three fan-shaped spring arms 1 are nested with each other in a circular surface to form a ring-shaped three-leaf spring a10; the three fan-shaped spring arms are arranged separately, ...

Embodiment 2

[0047] like Figure 9 As shown, the spring b51 is two sets of leaf springs, the structure of which is the same as that of embodiment 1. The spring b51 suspends the push piston rod 52, so that the piston b54 is suspended in the cylinder, forming a back working chamber 56 and a front working chamber 55, and the piston The b 54 can reciprocate under the impetus of the pressure fluctuation among the front working chamber 55 , the back working chamber 56 and the air storage 57 . All the other are with embodiment 1.

Embodiment 3

[0049] like Figure 10 As shown, the leaf spring is integrally formed by three fan-shaped spring arms. Mounting holes are provided at both ends of the three fan-shaped spring arms. The inner ring 7 of the formed annular leaf spring is connected, and the outer ring 6 is connected outside. Make installation more convenient. All the other are with embodiment 1.

Abstract

The invention relates to a fan-shaped spring arm, a leaf spring comprising the fan-shaped spring arms, and a compressor with the leaf springs. The fan-shaped spring arm comprises at least two fan-shaped arms and a transition circular arc, wherein the fan-shaped arms are connected through the transition circular arc. The leaf spring comprises at least three fan-shaped spring arms, wherein the fan-shaped spring arms are connected with each other in a sleeving mode so that the annular leaf spring can be formed. The compressor with the leaf springs comprises a stator (3), a rotor (2), an air cylinder a (46) and a piston a (44), wherein the piston a (44) is suspended in the air cylinder a (46) through a leaf spring a (41). Compared with the prior art, the fan-shaped spring arm, the leaf spring comprising the fan-shaped spring arms, and the compressor with the leaf springs have the advantages that the structure is reasonable, and the space utilization is high.

Description

technical field [0001] The invention relates to a reciprocating mechanism or a compressor, in particular to a fan-shaped spring arm, a leaf spring composed of it, and a compressor using the leaf spring. Background technique [0002] The compressor of a Stirling refrigerator or a pulse tube refrigerator is generally an oil-free lubrication compressor. In order to obtain a long life, a leaf spring is used to suspend the piston in the cylinder, so that the piston and the cylinder do not contact, and a gap is formed between the piston and the cylinder. The small gap forms a gap seal, which not only achieves the sealing effect, but also keeps the piston and cylinder out of contact, thus achieving long life. [0003] Leaf spring is a kind of spring with great radial stiffness and moderate axial stiffness. Generally, the compressor is cylindrical, and the leaf spring is correspondingly circular. The leaf spring is made of three or more spring arms processed on a circular steel pla...
