Embodiment 1

[0021] As shown in Figures 1 and 3.

[0022] A laminated torsion spring, which consists of a spring body 1 and a fixing seat 2 installed at both ends of the spring body 1, as shown in Figure 1, the fixing seat 2 is provided with a rectangular or square hole for inserting the end of the spring body 1 , the spring body 1 is formed by stacking two or more thin steel plates 3 with elasticity, the force acting point of the torsion arm 4 in the middle should be located on the center line 5 of the spring body 1, and the two thin steel plates 3 The ends are riveted together by rivets, such as image 3 as shown,

[0023] The torsion action point of the torsion spring in this embodiment is located in the middle section, and the control of the torsion force can be realized by rationally designing the thickness and width of the thin steel plate 3 and adjusting the position of the torsion action point. This embodiment can be used in occasions where the torque is large, the rotation angle...

Embodiment 2

[0025] Such as figure 2 , 3

[0026] A laminated torsion spring, which consists of a spring body 1 and a fixing seat 2 installed on the middle section of the spring body 1, such as figure 2 As shown, the fixed seat 2 is provided with a rectangular or square hole for inserting the spring body 1. The spring body 1 is formed by superimposing two or more elastic thin steel plates 3, and the force of the torsion arms 4 at both ends All points should be located on the center line 5 of the spring body 1 to ensure the linearity, controllability and calibration of the torsion force. The two ends of the thin steel plate 3 are connected by rivets, such as image 3 shown.

[0027] The torsion action point of the torsion spring in this embodiment is located at both ends of the spring member 1, and the control of the torsion force can be realized by rationally designing the thickness and width of the thin steel plate 3 and adjusting the position of the torsion action point. This embodim...

Abstract

The invention provides a laminated torsion spring, which is characterized by consisting of a spring body and a permanent seat, wherein the spring body is at least laminated by two elastic thin steel plates; and the permanent seat is arranged on two ends or in the middle section of the spring body. The laminated torsion spring breaks through the restriction of the traditional concept, and uses the torsion resistance of the thin steel plate to prepare the stripe torsion spring, thereby a novel type of the torsion spring is added, and the application field of the torsion spring is expanded further. Meanwhile, the torsion spring has the advantages of simple structure, convenient manufacture, wide application range, adjustable and calibrated torque force.

Description

technical field [0001] The invention relates to a mechanical part, in particular to a torsion spring, in particular to a laminated torsion spring. Background technique [0002] As we all know, torsion spring is a very common reset component. It has a very wide range of uses in the fields of mechanical structures and daily necessities. For a long time, there was only one form of torsion spring—the helical structure. Due to the limitation of this structure, it is difficult to be used in many special occasions, such as occasions with large torque and small stroke, large torque and slender strip installation space, and occasions where variable torque is required, so it is impossible to use helical torsion springs. The positioning, installation, and manufacture of torsion springs will become very difficult, and sometimes even difficult to achieve. In addition, in some occasions, it is necessary to use multiple torsion springs with consistent torsion to ensure consistency of act...
