    springs are a mechanical part that use elasticity to work. Generally made of spring steel. It is widely used in machines and instruments to control the movement of machine parts, mitigate impact or vibration, store and store energy, measure force, etc.The spring is just an accumulator, it has the function of storing energy, but can not release the energy slowly, to achieve the release of this function should rely on the 'spring + large transmission ratio mechanism' to achieve, common in the mechanical table.The spring is widely used in the mechanical and electronic industry. The spring can produce a large elastic deformation under load and convert mechanical work or kinetic energy into deformation energy. After unloading, the spring's deformation disappears and returns to its original stat...

We can look at the relationship between the force applied to a spring and its resulting displacement. Again, there are three classes of springs: linear (or constant rate) springs, variable rate springs, and constant force springs.Linear springsLinear springs obey Hooke’s Law (F=k*x), which means that the force needed to extend or compress such a spring by distance x is proportional to the distance, as long as the force doesn’t exceed the elastic limit of the spring. Torsion springs obey an analogous version of Hooke’s Law (F=k*θ, where θ is an angle). In both cases, k is the spring rate, and i...

Detection of the characteristics of 7.2 torsion springsWhen measuring torque, the size of the torsional spring axis must be suitable. The inner diameter of the spring should be kept to a certain gap, and the friction force and friction torque caused by the contraction of the inner diameter of the spring should be avoided, and the measurement accuracy should be affected. But the spindle can not be too small, otherwise it will cause the offset between the external torque and the measuring torque center, resulting in the error of the torque measurement. The specific testing program for torsion sp...

1、What is Passivation?As a post-fabrication method, passivation is intended to maximize the natural corrosion resistance of stainless steel. Stainless steel is a steel alloy that contains a minimum of 10.5% chromium content by mass and along with a number of other alloys. When stainless steel is newly formed it needs to be cleaned of lubricants, oils, greases and other substances used in its fabrication. Once the steel has been cleaned it must be passivated. Passivation is a process that treats metal surfaces with an acid solution to make the surface corrosion resistant.Passive to atmospheric conditions by removing the free iron from the surface that causes corrosion. Once treated with an acid solution, slowly and naturally a passive layer develops on the surface of the steel as the chromi...

Helical springsMaterials necessary for every aspect of daily life.  Helical spring is a spring that is subjected to torsional deformation, and its working part is also tightly wound into a helical shape. Its characteristic line is linear, can make compression spring, stretch spring and torsion spring. When the load is large and the radial size is limited, two compression springs with different diameters can be used together to become a combination spring. The total winding number n1 is the sum of the effective winding number n and the supporting winding number n2. Volute coil helical spring can store more energy and bear more load, but the manufacturing process is more complicated. The performance of the concave spiral spring is similar to that of the conical spiral spring.1. The...
