Aufbau und Funktion der Twin Spring oder Motor Brush Spring

One of the most unique spring designs is called a twin spring. Its name is derived from the characteristic of having two springs formed from the same strip of stainless steel material. These custom springs are intended to work together, in unison, doubling the force of a single spring. Twin springs are a version of a constant force spring, providing constant force throughout the travel length.
The area between the two coils is referred to as the saddle area, which is formed to fit over the part or component that is being pushed. The saddle can also be cut-out to provide access to the component and is best designed when assigned a dimension to fit over that specific part. It can be located at different heights between the coils for ease of assembly or as an indicator for direction.
Twin springs are used in a wide range of applications where available space is limited and a relatively strong force is required. Medical devices and surgical mechanisms incorporate this design to push or feed surgical staples in disposable skin staplers. Electric motors utilize the twin spring to provide a constant force on the carbon brush, extending the life of the motor and increasing reliability and overall quality. These springs are also referred to as motor brush springs.
Advantages of twin spring:
1. Under the same elasticity, the double winding spring saves volume.
2. Because the shape is symmetrical, the output is more stable.
3. Increase the length of available carbon brushes.
4. The outer diameter of the motor can be reduced.
