GB/T 1972 Can Belleville Springs Be Used for Anti-loosening?

Comparison of Advantages and Disadvantages of DIN2093(GB/T1972) Disc Spring and DIN6796 Disc Gasket

GB/T 1972 Disc springs and DIN6796 disc gaskets are similar in structure and material.
1. Two specific applications?
2.GB/ T 1972 disc spring can be used to prevent loosening? (At present, many manufacturers refer to this standard part as butterfly pad)
3. Can the two be mixed?
At present, it is planned to use a butterfly pad on a bracket near the engine for anti-loosening (use a nut butterfly pad to fix the bracket (the nearby vibration load is large)), but because the two washers have not been contacted before, a GB/T 1972 disc spring is actually used, which is no risk?

1.GB2093 is mainly used for shock absorption and dynamic load of the occasion, instead of cylindrical spring, DIN6796 is mainly used for bolt and nut connection pair anti loose effect;

2. First of all, understand the anti-loosening principle of the conical spring washer. After the spring washer is flattened, the spring washer will generate a continuous elastic force, which will generate contact pressure between the internal thread of the nut and the external thread of the bolt. This pressure generates friction resistance torque, thus preventing the nut from loosening, so theoretically it can be used for anti-loosening;

3. Due to the different design sizes of the two standards, if the anti-loosening effect of the same specification is definitely different, the DIN2093 thickness is DIN6796 thinner, the resulting resistance torque is relatively small, and the vibration load of your equipment is large, which is prone to the risk of anti-loosening failure! So in principle can't mix!
