Torsion Springs
Torsion springs are industrial spiral spring made from spring steel. It generates torque or rotational force through elastic deformation.
Structure and Principle for torsion springs
The torsion spring stores energy through the torsional elastic deformation of the spiral coil. The rotation direction can be either clockwise or counterclockwise. The ends can be machined into hook shapes or straight torsion arms to adapt to different loads. The design parameters include the control diameter, wire diameter, total number of coils, and end forms, etc. The materials commonly used are stainless steel, alloy steel, etc. They need to undergo heat treatment and surface treatment to enhance performance.
Application fields
Spring levers are widely used in door opening mechanisms, switch closing devices, and surgical instrument assist systems, etc. The angle that a spring can twist is limited by the tensile strength and shear strength of the material. Modern production equipment mainly includes computer spring forming machines and heat treatment equipment.
Materials and Specifications
Common materials include stainless steel, piano wire, and special alloys. The specifications distinguish between left-handed (L) and right-handed (R) directions. The outer diameter tolerance is controlled within ±2%. The end forms are designed according to application requirements. For piano wires, three end positions are usually available, while for stainless steel products, four end positions are provided.
