According to what parameters to choose the compression springs

1. Definition

Coil compression springs, referred to as compression springs, is this kind of spring used to withstand and resist axial pressure. Among all types of springs, compression springss are the most common type, and they are all mechanical components with the most reasonable energy storage. In addition to the general cylindrical shape, other shapes are often used, such as conical, convex and concave. Under normal conditions, this spring is either passed through a shaft or placed in a hole. When you apply a load to the helical compression springs, the spring becomes shorter, then resists the load, and eventually returns to its original length.

2. Scope of application

From automobile engines, large presses to key household appliances, lawn mowers, from medical equipment, mobile phones to precision instruments, compression springss have a very wide range of applications. Before purchasing a compression springs, be sure to clarify the manufacturing industry and working conditions of the compression springs you must use, because this is directly related to the selection of spring materials.

 3. Coil direction

The direction of the coil of the compression springs is like the thread of a screw, which can be left-handed or right-handed. In use, if you must put one spring in the other spring, you must ensure that the rotation of the two springs is opposite, one left and the right; if you must screw the bolt in the spring, you must ensure the rotation of the bolt and the spring The directions of rotation match.

4. Number of turns

The total number of turns refers to all the coils from the top of the spring to the other top. Regardless of whether the ends are tight or tightly polished, there is often an incomplete coil at both ends of the compression springs, which is not a reasonable number of turns and is only used to support the upper and lower ends. The reasonable number of turns refers to the number of complete turns that can play the role of the spring, and any part of the spring can store and release energy. For the compression springs, when the compression springs is under pressure, the reasonable coil can expand and resist the pressure. When designing a spring and clarifying its size, because the number of turns has a great hazard to the strength of the spring, it is particularly important to count the number of turns of the spring. The clarification of the number of turns is fairly straightforward, that is, starting from one end of the spring, that is, the position where the wire is cut, and then the wire is rotated. Every 360° is counted as a complete coil (180°=0.5 turns, 90°=0.25 turns).
