Disc springs

Technical springs

Disc springs are used in small spaces and can generate large forces. For the calculation of cup springs, we refer to DIN 2092.

TEVEMA disc springs are manufactured under strict quality standards and according to DIN 2093 load characteristics.

Ordering Disc springs

TEVEMA is supplier of disc springs. Disc springs are round steel products usually with a hole in the middle. The roundness slopes slightly upwards or downwards from the outside to the inside and gives it spring. The disc springs can absorb a heavy load/pressure and require relatively little space. Because of the unlimited number of possible combinations in large, curved, length, thickness and shape, disc springs can be used in many different ways. The disc springs can be placed on top of one another to provide more power. Because of their round shape, the disc springs are concentric in power transfer.

Advantages compared to other types of springs are

  • Can absorb a lot of pressure with little deflection
  • Saves space
  • Constant performance
  • Longer lifespan
  • Inherent damping, especially when disc springs are placed on top of one another
  • Flexible in construction of multiple disc springs on top of one another.

Disc springs are manufactured according to the DIN EN 16983 (former DIN2093) standard. Disc springs are divided into groups and series.

Series of disc springs

The series of disc springs consist of two groups. Group one has a thickness of <1.25 mm and group two has a thickness of 1.25 to 6 mm. Anything exceeding these dimensions means the disc springs are no longer in a group. There are three series of standard disc springs. These series of disc springs are simple: Series A, Series B and Series C. The series of disc springs are laid down in the EN 16983.

Series A has all disc springs in which the external diameter divided by the thickness of the steel is 18 or less and the free length divided by the thickness of the steel is 0.4 or less.

Series B has all disc springs in which the external diameter divided by the thickness of the steel is between 28 and 18 and the free length divided by the thickness of the steel is between 0.75 or less. Series C already has all disc springs in which the external diameter divided by the thickness of the steel is 48 or more and the free length divided by the thickness of the steel is 1.3 or more.

You can read more about the series of disc springs here.

Stacking disc springs

Different forces can be produced by stacking disc springs. There are three types of stacks of disc springs. The disc springs can be stacked in parallel, in series and in series with parallel stacks. The complete calculations and possibilities of the series are explained here. Simply put, parallel stacking ensures that the forces placed on the disc springs are increased but how far the disc springs can be pressed remains the same. In series, stacking ensures that the forces remain the same but that the disc springs can be pressed further and parallel in combination with series can cause additional forces and compression in linear, progressive and regressive ways.
