The anti loosing principle of the wave spring washer is that after the wave spring washer is flattened, the wave spring washer will produce a continuous elastic force, which makes the screw connection pair of the nut and the bolt maintain a continuous friction force, and produces a resistance moment to prevent the nut from loosening. At the same time, the sharp corners at the opening of the wave spring washer are respectively embedded into the surface of the bolt and the connected part, so as to prevent the bolt from rotating relative to the connected part.
How about the anti loosing effect of wave spring washer?
Wave spring washer is widely used in the load-bearing and non load-bearing structures of general mechanical products. It is characterized by low cost, convenient installation and suitable for the parts with frequent assembly and disassembly. But the anti loosing ability of wave spring washer is very low! Especially in the European and American countries, the adoption rate of high reliability products is very low, especially the important bearing structure connection parts have been abandoned for many years. Our country still has some applications in military industry, but it has been improved to stainless steel. It is said that steel wave spring washer has been banned in CASC for a long time! That is to say, it is very unsafe. There are two reasons: one is the rising circle, and the other is hydrogen embrittlement.
