Helical torsion springs in a wide range of variations
Torsion springs can either have a left-hand or right-hand helix.
They are made to give a force and torque when one leg is turned
relative the other.
Our helical torsion springs are made in dimensions from 0.03- 26
millimeter and we select wire diameter, spring body diameter,
length and pitch to suit your requirements.
For closed coiled helical torsion springs there will be a friction
between the coils giving a hysteresis in the torque-angle
There are generally two common types, single and double coil
torsion springs. Normally is the coil controlled inside with a
mandrel but also an outer control with a cylindrical housing is
possible. With fixed assembled legs the spring type can work
without a coil body control. Tangential legs give the lowest
stresses but also radial and axial legs of different types are
possible. In many cases the strain in the legs must be considered
in the design.
