A torsion spring stores energy by twisting or rotating a soft, resilient elastic material, releasing it using a lever principle to impart mechanical energy to the launched object. Modern torsion springs and torsion bars are mostly made of highly elastic steel and come in a wide variety of forms, including the balance springs in mechanical watches, the power springs in toy spinning tops, and the torsion bars in tanks and automobiles. Torsion bars are small in size and have high torque, making them ideal for shock absorption in transportation vehicles.
1. Shock mitigation and vibration absorption: These springs have a large elastic deformation capacity, absorbing vibrations and impacts. Examples include buffer springs in automobiles and trains, and vibration-damping springs in couplings.
2. Controlling the movement of mechanisms: These springs require minimal force variation within a certain deformation range. Examples include valve springs in internal combustion engines, control springs in clutches, and springs in the cam mechanisms of automatic machine tools.
3. Storing energy: These springs require both high elasticity and stable force. Examples include watch springs, bolt springs, and springs in the automatic tool return mechanism of automatic machine tools.
4. Measuring the magnitude of force: This type of spring requires a linear relationship between force and deformation. Examples include the springs in force gauges and spring scales. There are many types of springs. Based on the load they bear, they can be divided into tension springs, compression springs, torsion springs, and bending springs. Based on their shape, they can be divided into helical springs, disc springs, ring springs, coil springs, and leaf springs.
