The difference between single-layer closed wave spring, open wave spring and lap wave spring

1.Wave closed-end spring: It is stamped from an annealed steel plate into a flat ring, and then uses a forming die to extrude the corrugated shape. It is then quenched to increase the hardness and strength of the product, and finally tempered and polished. It has the characteristics of small stroke and large load. Usually the peaks and troughs are in a gentle curve, and sudden bulges in the peaks are not allowed. The closed wave spring is made by stamping, and there are dark tear marks on the edge of the product during stamping, which affects the service life.


2. Open wave springs and lapped wave springs are made of round steel wires that are rolled into flat steel wires 4 to 6 times, then rolled into shape using a spring coiling machine, and finally stress-relieved and tempered. Compared with wave-shaped closed springs, they have higher The material utilization rate is more than 90%. Because the steel wire has been rolled multiple times, it also has higher toughness and strength. Notched and lapped compression springs are suitable for a variety of applications. They function precisely and reliably in applications with small deformations and low to medium force values.


3. When the opening wave spring is compressed, the opening will automatically shrink, which can be used as a circlip and absorb vibration. Therefore, this end is free to move circumferentially as the outer diameter of the spring grows during compression.

4. The lap wave spring has two layers of thickness at the lap. Under extreme compression, the working height is at least twice the wire thickness. It has a built-in limit function, which can prevent excessive stress on the product caused by overloading of the working load. It usually has a higher High fatigue life and long service life.
