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
