Correct design steps for tension springs

What is a tension spring? In fact, tension spring is a spring that is often used in our life. Tension spring is also called tension spring. Tension spring is a coil spring that accepts axial tension. Tension spring is generally made of circular cross-section material. When it does not bear load, there is no gap and tightness between tension springs.

There are two basic designs of tension spring: pre-tension spring and non-internal pre-tension spring, and the correct design steps of tension spring. Pre-tension spring Cold bending spring is suitable for pre-stressed machining, so the working coil is closed, pre-loaded spring can increase the bearing capacity of the spring, for the specified length of spring deformation, high load without preload should be used, pre-compression occurs in the winding process of the spring coil, size depends on the material used, spring index and winding method, 2. If there is no pre-tension spring inside, if it is not needed for technical reasons, loose coil spring can be used without pre-tension. There is a gap between working coils. The task of spring design is to determine the geometric size of spring wire, such as diameter D and number of working turns N, so as to meet strength constraints, stiffness constraints and stability constraints. The progress also requires corresponding design indicators.(such as volume, weight, vibration stability, etc.) to achieve better results, the correct design steps of tension spring are as follows: according to the working conditions, requirements, etc., try to choose the tension spring material, spring index is usually pre-assumed, and calculate the diameter d of the spring wire, and then calculate the d and n values and other corresponding geometric size, if the results do not meet the design conditions, should repeat the above process.

  Many different terminal devices can be "hooks" to ensure the starting tension of the tension spring. Elastic springs work on the opposite principle of compression springs. Tension springs act opposite to compression springs. Tension springs act opposite to tension springs when they open or expand. When the ends of tension springs expand, the springs try to pull them back. Like compression springs, elastic springs absorb and store energy. However, unlike tension springs, most tension springs usually work under a certain tension. Even without any load, this initial tension determines how tight the spring is when there is no load.
