Custom Torsion Spring Solutions
Thanks to their unique structure, precise torque output, high energy storage density, and stable return performance, torsion springs are widely used in various precision mechanical systems that require rotational torque or angular return.
-
Torque-angle linear relationshipWithin the elastic deformation range, torque is directly proportional to the torsional angle, as given by the formula: T = k·θ, where k is the torsional stiffness.
-
Controllable torsional stiffnessPrecise design of stiffness values by adjusting parameters such as the number of coils, wire diameter, mean diameter, and material elastic modulus
-
High energy storage densityHigh elastic potential energy per unit volume, making it suitable for return mechanisms with limited space
-
No initial preloadIn a free state, the torsion arm has no relative positional constraints, allowing for flexible installation.
-
Preloadable designApply an initial torque angle during installation to achieve the preload torque output
