The function of the cushion:
1. The function of a spring washer is to provide an elastic force to the nut after tightening it, which tightens the nut and prevents it from easily falling off. The basic function of a spring is to apply force to the nut after tightening, increasing the friction between the nut and bolt.
2. Generally, flat pads are not used when using spring pads (except when protecting the surface of fasteners and installation surfaces).
3. Flat pads are generally used in connectors, with one being soft and the other being hard and brittle. Their main function is to increase the contact area, disperse pressure, and prevent the soft material from being crushed.
advantage:
① Spring washers have good anti loosening effect;
② Spring washers have good seismic resistance;
③ Low manufacturing cost;
④ Installation is very convenient.
Disadvantages:
Spring washers are greatly affected by material and process. If the material is not good, the heat treatment is not handled properly, or other processes are not done properly, it is easy to crack. Therefore, it is necessary to choose a reliable manufacturer.
3, When to use flat pads and when to use elastic pads?
1. In general, flat pads can be used only when the load is relatively small and does not bear vibration loads.
2. In situations where the load is relatively large and subjected to vibration loads, a combination of flat pads and elastic pads must be used.
3. Spring washers are generally not used separately, but in combination.
In practical use, due to the different emphasis of flat washers and spring washers, they are often used in conjunction with each other to protect components, prevent nut loosening, and reduce vibration. This is a great choice.
