In fact, the service life of clutch springs is related to their own fatigue strength, and there are multiple factors that affect the fatigue strength of springs. Therefore, in order to better ensure the service life of clutch springs, it is necessary to start from various factors. So, what are the factors that affect the fatigue level of clutch springs? Next, let's invite professional technicians to give you a detailed explanation so that you can have a better understanding of it.
The main factors affecting the fatigue strength of clutch springs are:
1. Yield strength
There is a certain relationship between the yield strength and fatigue limit of materials. Generally speaking, the higher the yield strength of a material, the higher its fatigue strength. Therefore, in order to improve the fatigue strength of a spring, efforts should be made to increase the yield strength of the spring material, or materials with a high ratio of yield strength to tensile strength should be used. For the same material, fine grain structure has a higher yield strength than coarse and fine grain structure.
2. Size effect
The larger the size of the material, the higher the possibility of defects caused by various cold and hot processing techniques, and the greater the possibility of surface defects, all of which can lead to a decrease in fatigue performance. Therefore, the influence of size effects should be considered when calculating the fatigue strength of springs.
3. Corrosive media
When a spring works in a corrosive medium, it becomes a fatigue source due to pitting corrosion on the surface or corrosion of surface grain boundaries. Under the action of variable stress, it gradually expands and leads to fracture. The influence of corrosion on the fatigue strength of springs is not only related to the number of times the spring is subjected to variable loads, but also to its working life. To ensure the fatigue strength of springs working under corrosive conditions, materials with high corrosion resistance, such as stainless steel, non-ferrous metals, or surface protection layers such as plating, oxidation, spraying, painting, etc., can be used. Practice has shown that cadmium plating can greatly improve the fatigue limit of springs.
4. Temperature
The fatigue strength of carbon steel decreases from room temperature to 120 ℃, increases again from 120 ℃ to 350 ℃, and decreases again after the temperature exceeds 350 ℃. There is no fatigue limit at high temperatures. Springs working under high temperature conditions should consider using heat-resistant steel. Under conditions below room temperature, the fatigue limit of steel increases. The current passing through the coil can be adjusted by changing the contact pressure of the horn contacts. The adjustment of the volume of the electric speaker can be achieved by adjusting the screw to adjust the contact pressure, thereby adjusting the volume.
