[0002] The shear spring is also called a steel plate sandwich rubber shock absorber, which is made of steel plate sandwich high-quality natural rubber, and is mainly used for high-frequency vibration equipment. In a linear vibrating screen, the screen machine is driven by a vibration exciter to vibrate at a certain amplitude, and the frequency is relatively fast. At this time, the shear spring is used to connect the screen box and the support body, and the two ends are fixed and installed by positioning pins, which is convenient, safe and reliable, and has a long service life.

[0003] In order to detect the tension of the shear spring, professional instruments are needed to test the tension of the shear spring.
