Disc Springs


disc_springs.jpgThe disc springs are angular disc like springs. It is a conical designed springs. The disk springs are believed the best solutions to many engineering problems. The disc springs are also called the washers. The disc springs have the best space utilization. It has high load capacity. By arranging them into stacked columns, the big amount of variable spring characteristics can be achieved.

 

  • Spring Steel 0.20 to 20 mm wire diameter
  • Material customized as per client’s requirement


Introduction

The disc springs are the good example of the equal combination of high force in a small space. To meet the requirement of the customer for the special application, the program is design by the computer. The disc springs are obtained with or without contact flats. Most of Belleville washers and Disc springs are manufactured from DIN 2093 and DIN 6796. The material used to manufacture the disc springs are 17/7PH, 304, 50CrV4. Conical shaped disc springs were first made by Julian Belleville, named after him the Belleville washer. The disc springs are used as a energy storage system in internal combustion engine, nuclear power, oil and gas exploration, turbine and jet system.

Disc Spring Stack and Hellical Spring

disc_spring_stack If the same stress is given to both the system, the disc spring stack and coil spring, the result is varied. Disc stacks are designed for a high loads and coil springs are not been practicable.

Stalk Length

stack_length A rule of thumb is applied in stacking the disc springs. When stacking the disc springs the stacks should kept as short as possible. Friction and other power make a stack uneven. The guide washers stabilize the stack, if it is longer. The thickness of guide washers should have one and a half times than the guide diameter.

 

Advantages of Disc Springs

  • As the individual spring sizes are combining, it minimizes the stock keeping.
  • It is space saving.
  • Low cost for maintenance
  • Higher energy storage capacity
  • Long service life
  • The high spring force and good use of space
  • No tiredness or deformation
  • Good shock absorption and energy dissipating
  • Adaptable to stacking in numerous configuration


Disc Springs in Series and Parallel Combinations

Total Load = Load on 1 disc X no. of discs.

Total Deflection = Deflection of 1 disc X No. of discs in stack. Total Load = Load on 1disc.

Stacked in Parallel Series:

To obtain the quality either progressive or regressive, the combinations of the load or deflection can be designed virtually.
