Dec 14, 2022
Spring washers, also known as split lock washers, spring lock washers. Its materials are stainless steel, carbon steel, rubber, plastic, and other materials. The commonly used sizes of spring washers are m3, M4, M5, M6, M8, M10, M12, M14, and M16. Spring washers are widely used in load-bearing and non-load-bearing structures of general mechanical products. It is characterized by low cost, convenient installation, and is suitable for parts that are frequently disassembled and assembled.
The role of the spring washer:
The function of the spring washer is that after the nut is tightened, the spring washer gives the nut an elastic force to tighten the nut so that it is not easy to fall off. The basic function of the spring is to apply force to the nut after tightening it to increase the friction between the nut and the bolt.
Spring washers are generally used on connectors, one is soft and the other is hard and brittle. Its main function is to increase the contact area, disperse the pressure, and prevent the soft texture from being crushed.
Spring washers are used to prevent loosening. For example, the bolts connecting the motor to the base should be fitted with spring washers. If the motor vibrates, the nut will come loose without the spring washer installed. Generally, spring washers are installed on the fasteners of equipment with vibration, and no washers are required on the flange! Whether the flange is equipped with a spring washer is related to the medium flowing through the pipeline. If it is easy to generate pulses, it is best to add spring washers, as well as high-speed fluid, and the caliber changes frequently. To adapt to local conditions, do not generalize.
Advantages of spring washers:
1. Good anti-loosening effect;
2. Good anti-seismic effect;
3. Low manufacturing cost;
4. The installation is very convenient.
Disadvantages of spring washers:
Spring washers are greatly affected by material and workmanship. If the material is not good, the heat treatment is not good, or other processes are not in place, it is easy to crack. Therefore, it is very important to choose a reliable manufacturer.
When to use flat washers and when to use spring washers?
In general, flat washers can only be used when the load is small and does not bear the vibration load.
In the case of large loads and vibration loads, both flat washers and spring washers must be used.
Spring washers are basically not used alone but in combination.
In the actual use process, due to the different focus of the flat washer and the spring washer, the two are used together on many occasions, which can protect the parts at the same time, prevent the nut from loosening, and reduce vibration, which is a good choice.
