Torsion Spring Design Examples

Torsion springs are stressed in bending.

Torsion spring design examples.

Torsion springs are used in torsion pendulum clocks. Torsion spring design theory. This force twists the coils tighter in turn reducing the spring diameter and making the body longer. Provisions relating to torsion and serviceability issues.

We have a wide range of cnc spring forming machines that can manufacturer custom torsion springs with wire diameters as small as 0 010 or as large as 0 250 0 25 mm to 6 4 mm and any size wire in between. From medical torsion springs to automotive torsion springs our springs can be produced with wire diameters ranging from 0 005 to 0 250 and designed to rotate either counterclockwise or clockwise. No matter what the specifications of your application a custom torsion spring can be manufactured to suit your needs. Torsion spring design torsion springs exert a torque when they are twisted or deflected.

Torsion springs whose ends are rotated in angular deflection offer resistance to externally applied torque. Torsion springs are a type of helical metal spring that stores mechanical energy when twisted. The logic is as you wind a torsion spring clock wise to the right the torsion spring will decrease its inner diameter and outer diameter thus allowing the spring to enter into your worn out hole or bore. Here are some of the major areas of its application.

Rectangular wire is more efficient in bending than round wire but due to the premium cost of rectangular wire round wire is preferred. Torsion springs can be made out of round rectangular or shaped wire. Stress in torsion springs the coil of a torsion spring experiences bending stress despite the name of the spring. The design examples in chapter 5 illustrate the design process as well as the use of the design aids for torsional properties and functions found in appendices a and b respectively.

Whatever your torsion spring design size and tolerance needs master spring has the manufacturing capabilities to match. Torsion springs are particularly useful as door hinges. Finally appendix c provides supporting information that illustrates. From residential doors garage doors and automobile doors to large industrial heavy duty overhead doors used at loading docks and warehouses there s no doubt that the torsion spring is a vital component in all of the different types of doors.

Once twisted the spring exerts proportional force to the amount that s being applied but in the opposite direction. There are a number of applications where torsion springs find their use. A simple torsion spring has straight but any bends or shapes can be formed. Double torsion springs can.

The spring torque and the length of the legs together create a force. In such clocks a torsion spring is used to suspend a wheel shaped weight from the center of the clock.
