How long can constant force spring be used ?

kilde:Qianye præcision tid:2022-9-15

Fjeder med konstant kraft, also known as hair spring, is made of stainless steel strip. The force added to the spring determines the diameter, force and life of the spring. The action of constant force spring is similar to that of stretching ribbon. The spring stretches and rolls back, and the working part is tangent to the spring ‘ s own circle. As long as the diameter of the spring is certain, the force of the spring is constant.

According to the application principle of constant force spring, constant force spring can be divided into linear constant force spring and rotational constant torque spring. When linear stretching force units are : kg, Newton, pounds, etc.

    Then how long can the constant force bar be used ? The life of the constant force bar is limited, and the life requirement of the spring should be considered when designing the constant force bar. This step is important because it affects the things behind the design ; improper consideration may lead the design to a wrong direction ; properly considered, the design will be easier to succeed.

It is very important to determine the number of spring stretching before designing the constant force bar. Spring stretching times explanation : a refers to the spring in any part of a stretch and roll back process. Since the constant force spring provides force through the bending of the spring, any part used belongs to the spring body. In other words, a spring with a total design length of 25 ’ uses the length of 6 ’ and the length of 18 ’, and the number of stretching is the same.

In the initial design, it is very important to determine the number of stretching. It is natural to think that the longer the service life, the better, but it may design a larger spring. If the estimated number of stretching springs is too small, the service life of the final product will be shortened. Considering the spring life needs to be based on the actual situation, because if considering too long life will lead to the design of spring cost is high, spring size becomes larger ; if the estimated life is too small, it will lead to premature failure of the product. Usually the use of constant force bar applications are from 4000 to 25000 times. If you consider higher service life, consider increasing the error range of spring diameter and force.
