Description

Planar scroll springs, also known as clockwork springs, are springs with torsion; under the action of torque, the spring material produces bending elastic deformation, which makes the spring torsion in the plane, and its deformation angle is proportional to the torque.

Feature

The characteristic of the scroll spring is that it is easy to bend in only one direction-the minimum stiffness plane, and has a large tensile stiffness and bending stiffness in the other direction. Therefore, the leaf spring is very suitable to be used as sensitive components, elastic supports, positioning devices, flexible connections, etc. in detection instruments or automatic devices.

Application

The Scroll springs are the simplest springs that use the deformation of elastic metal sheets to produce spring characteristics. The elastic metal sheets are rectangular, trapezoidal, and triangular, and can also be straight or curved. It is usually used in places where the load and deformation are small and the rigidity is not large, such as the sensitive components, elastic supports or positioning devices in instruments, meters and automated mechanisms. Such as electrical on-off contacts, etc.
