Belleville Spring

Most Belleville washers and disc springs are fabricated from the DIN 2093 and DIN 6796 and from the material 177 PH, 304 and 50crv. The Belleville washer is named after julian Belleville, which are conical in shape and used as a energy storage system in internal combustion engine, nuclear power, oil and gas exploration, turbine and jet system. While stalking disc springs, rule of thumb is applied. Stalks are kept with possible shorter length. Friction may make stack uneven. The guide washer is longer, which stabilize the stalk. The thickness of guide washers should have one and a half times than the guide diameter. Advantages.
