Double torsion springs are used in a wide range of applications, such as clothing pins, clipboards with paper clips, tailgates, and garage doors. Double torsion springs are also used in hinges, balance bodies and handle return devices. This double torsion spring comes in many sizes, such as miniature double torsion springs for electronic equipment and large double torsion springs for seat controls. Double torsion springs should be loaded according to the direction of rotation; rotation from positions other than the free position is not recommended. When the double torsion spring rotates, the diameter becomes shorter and the spring body becomes longer. This should be considered when design space is limited. Double torsion springs work better when supported by rods or tubes.
1. Configuration and application of double torsion spring
Store and release angular energy or statically fix a device by rotating the moment arm about the central axis of the spring body. Torsion double torsion springs are usually tight, but have a pitch between the coils to reduce friction. They provide resistance to rotation or external rotational forces. According to the application requirements, the rotation direction of the torsion double torsion spring (clockwise or counterclockwise) is designed to determine the rotation direction and configuration of the double torsion spring.
2. Application of double torsion spring balance system
No matter how big or heavy the door is, it can be pushed, pulled, and closed to move up and down easily. The double torsion spring should be able to exceed the corresponding requirements for the number of opening and closing doors to ensure that it does not break within the set service life. The balance system consists of: wire rope pulley, solid shaft, bearing bracket, double torsion spring, flange, wire rope, depending on the door body.
3. Application of cylindrical spiral double torsion spring in gapless linear transmission mechanism
The mechanism uses steel belt, single pulley, and cylindrical spiral double torsion spring to achieve seamless linear transmission, which reduces the number of knots, reduces the complexity of assembly and adjustment, and improves reliability. A single cylindrical screw double torsion spring is used to tension the steel belt, which simplifies the complexity of the tensioning mechanism.
4. Application of double torsion spring in sliding door balance system
Application of double torsion spring in sliding door balance system: The torque generated by the balance system should be equal to the weight of the door. No matter how big or multiple the door body is, it can be used for sliding and closing, and it can run up and down easily. The double torsion spring should be able to exceed the corresponding requirements for the number of opening and closing doors to ensure that it does not break within the set service life.
