What Is a Belleville Washer?

Disc springs, also known as Belleville spring washers, were invented by the French, Belleville. Disc washers (DIN6796 DIN2093 DIN2092 DIN6796) (HDS series) are lock washers designed for bolt and screw connections. It is designed and manufactured according to DIN 6796 for the connection of medium or high strength bolts and screws.

Lock washers for bolt and screw connections

The large support load and elastic recovery make the HDS series very effective. The bolt tension can withstand the relaxation caused by the following reasons: wear of the consumables, creep, relaxation, thermal expansion, shrinkage, or compression of the seal. The HDS series increases the elastic effect of the screw several times. It can effectively replace ordinary spring washers, but it is not suitable for the combination of lock washers and flat washers.

Because the HDS series is a disc spring that can be mated or superimposed. The combination of the pairing method can increase the deformation of the disc spring group, and the combination of the combination method can increase the spring force of the disc spring group. The ideal installation method is to flatten as much as possible, the closer it is to the flattening state, the faster the tensile torque increases, and a proper bolt tension can be obtained without the need for a torque wrench.
