The common function of a Torsion Spring is to twist and then come back to its original position. The most familiar use of a torsion spring is on the old-fashioned clothespin. The rugged torsion spring joins the middle of the classic wood body. As we all have seen, when the user clasps open the clothespin, positions it over the clothes, and releases; the pressure of the torsion spring secures the clothes on the line.

Thousands of other torsion spring applications work much the same way; from safety pins and mousetraps to clipboards and garage doors. In any application where the need exists for rotational force, a torsion spring is likely to be right for the job.

A torsion spring is used when there is a need for rotational torque. There are two types of torsion spring designs – single and double, with single torsion springs being the most common type. When a Torsion Spring is assembled over a shaft, it is important to note that, as the spring is rotated in a normal direction, the inner diameter reduces which can cause binding on the shaft along with unnecessary stresses to the spring; it is critical to take into consideration the inside diameter of the spring along with the shaft size it works over. Typically the more malleable spring materials.

Application of Torsion Springs

There are a number of applications, where torsion springs find their use. Here are some of the major areas of its application:

  1. Clocks: Torsion springs are used in torsion pendulum clocks. In such clocks, a torsion spring is used to suspend a wheel-shaped weight from the center of the clock. As the weight rotates around its axis, it twists the spring. As per its nature, the spring exerts an equal opposite force on the wheel and makes it twist in the other direction. Thus, there is a continuous back and forth motion of the pendulum, which makes the clock work by driving the gears to which it is attached.
  2. Clothes Pins: This is one of the most common applications of these springs. The working of clothes pins is facilitated by the torsion springs. These springs provide an excellent clamping action, which is why they are used in this application.
  3. Automotive: Torsion springs are known for providing even tension, along with smooth and frictionless motion. This is the reason why these springs are widely used in the automotive industry for various parts such as a vehicle suspension system, chassis, automotive valves, clutches, and gear shifters. These springs are made from materials like chrome silicone, which makes it resistant to environmental abuse, along with providing it additional strength.
  4. Medical Equipment: In the medical industry, the torsion springs are used in a number of complex equipment. Different medical equipment that make use of these springs include medical immobilization devices, hospital beds, several dental applications, wheelchair lifts and many more. For additional strength, these springs are made from high carbon steel, which also helps increase the life span of the spring.
  5. Door Hinges: These springs are widely used in different types of door hinges. Right from automobile doors and residential doors to heavy duty doors at warehouses, torsion springs are used in the hinges. These springs allow the door to come back to its original position. You must have noticed the doors in saloons that move back and forth when opened, but ultimately become stationary at their original position. This is due to the springs used in their hinges.
