Disc Spring Stacks

The required various load/deflection characteristics of Belleville disc springs can be obtained from the various stacking combinations. The stack combination methods and load&deflection relation as the table below.

1. Stacking in Parallel		The load of the stacking disc springs in parallel will be in direct proportion to the number of single disc springs making up the stack.
2. Stacking in Series		The deflection of stacking disc springs in series will be in direct proportion to the number of single disc springs making up the stack.
3. Stacking in parallel & series combination		Almost any required load/deflection characteristics can be obtained from the different design of stacking combination.

The designed & expected load/deflection characteristics of disc springs stack just be reached under the correct installation. A guiding element is necessary to keep the disc springs stack in position. This should preferably be a mandrel. HEGONG SPRING® can deliver disc springs stack pre-assembled on a guiding element and highly recommend this way.

Advantages of disc springs stack:

1. Provide specific load/deflection data for the whole set of disc springs stack. (HEGONG SPRING®’s load testing machines can measure loads up to 4000KN)

2. Small load tolerance

3. Easier to install
