Cylindrical torsion springs are widely used and versatile machine components in the world of mechanics and spring technology.
The construction of a cylindrical torsion spring consists of a wire that is wound helically around a central axis in regular turns.
Torsion springs are used to absorb and deliver rotary movement, torque or force and guide the movement of the torsion springs.
Torsion springs are characterized by their ability to absorb and release deflections, forces or torques around an axis of rotation and to guide the rotary movement.
Torsion springs usually have a cylindrical spring body on which two legs are arranged.
The legs may be arranged tangentially, radially or axially, with each leg having a different arrangement.
Different spring end shapes can be attached to the end of the two legs, e.g. straight leg, hook shape, eyelet shape, round or square.
The terms "leg spring", "torsion spring" and "torsion spring" refer to the same component.
Torsion spring with tangential leg and inward leg
The basic structure of a torsion spring includes the following features:
The spring body consists of a helical coiled wire in a helix shape.
The spring body of the torsion spring is usually guided over a mandrel, axle or shaft.
The legs of the leg spring establish the connection between the force application points and the spring body.
Usually one leg is used to introduce the force and the other leg serves as a support.
The legs of a torsion spring can be arranged tangentially, radially or axially, with each leg having a different arrangement.
Different spring end shapes can be attached to both legs, e.g. straight leg, hook shape, loop shape, round or square.
Introduction of force or introduction of torque:
The introduction of force or torque takes place via one of the two legs of the leg spring, with the other leg usually being supported on a bolt, machine part or device part.
The angle between the legs changes due to the introduction of force or torque in the winding direction.
The torsion spring should be loaded in the direction of the coil.
It is important to note that the exact designation (trigger spring, torsion spring, or torsion spring) can vary and is used interchangeably in different contexts.
It is basically the same component that is used to create rotating motion or torque.
Torsion spring with tangential legs
The mechanics of torsion springs, torsion springs, torsion springs:
The torque or the force that should act on the torsion spring should be in the direction of the coiling in order to put less stress on the spring wire.
It is also possible to load the torsion springs against the winding direction. However, this fact must be taken into account in the design and calculation.
Due to the design and the introduction of force, the torsion spring is subjected to mechanical and strength-related bending loads.
Accordingly, the calculation must be carried out using the analytical bending equations for wire.
Here, the modulus of elasticity is an important material property.
In addition, torsion springs are usually designed for fatigue strength.
The fatigue strength diagrams for bending of the spring material or spring wire are helpful and of crucial importance.
If the torsion spring is loaded in the winding direction, the inner diameter Di of the spring body is reduced, while the length of the spring body Lk increases.
However, if the torsion spring is loaded against the winding direction, the inner diameter Di of the spring body increases, while the length of the spring body Lk decreases.
Basically, tight radii (wire bending radius smaller than 2 * wire diameter) should be avoided at the transition from the spring body to the two legs and from the legs to the different spring end shapes.
High stress peaks can occur there, leading to premature failure of the torsion spring.

High-quality torsion springs, torsion springs and torsion springs:
Torsion springs or torsion springs are helical springs that are bent around an axis and subjected to bending stress.
As kinematic components, they store potential energy and are essentially responsible for the moving functionality.
Torsion springs usually consist of two legs (Ls1 and Ls2) and a spring body (Lk) with a certain number of coils (n)
and a certain diameter (Di, Da). The legs that are present in the torsion springs have a special function.
In contrast to many classic springs, the legs of the spring act as levers.
This allows you to initiate the torque optimally.
Torsion springs, torsion springs and torsion springs for individual applications:
In addition to standardized torsion springs, you can also opt for individually adapted versions.
An adaptation of the leg geometry according to customer requirements is just as possible as bending the spring legs into a tangential,
radial, radial central or axial shape. These are just a few examples of how torsion springs can be adjusted.
If you wish to make further changes, simply contact us.
Adjustments are possible with the torsion springs as well as with the leg adjustment.
The leg position can be continuously adjusted to the expected forces or the required torque.

Typical features of torsion springs, torsion springs and torsion springs:
These wire springs are always wound helically. They have protruding, straight ends, which are also referred to as legs.
For torsion springs, the legs, i.e. the ends, are of great value. This initiates the torque for the bending wire.
Torsion springs are used very frequently in everyday life and are essential in many areas.
For example, they have become an important basic in clothes pegs or safety pins.
When closed, the safety pin is held in the so-called power lock by the torsion spring.
Even the mousetrap with a shock bar would not work without the torsion spring.
