Disc Springs

Discover the Power of the Disc Spring

Large forces, short distances, small installation space

COMPACT POWER PACKAGES IN ALL VARIANTS

Disc springs are flat, conical annular shells that can be loaded in the axial direction. Depending on the specific requirements of the application, a disc spring can be loaded either as a single spring or as part of spring columns, both at rest (statically) and in motion (dynamically). Typically, force is applied via the upper inner edge and the lower outer edge. Either an individual disc spring or spring assemblies, composed of several disc springs, can be alternately layered in a column.

HÄUSSERMANN disc springs efficiently support many dynamic processes, even under extreme force, high stress conditions, as well as in particularly challenging environmental settings.

CHARACTERISTICS

High spring force with small spring travel, large force absorption with small installation space. Additionally, any characteristic curves / spring characteristics can be achieved: spring characteristics with a linear, degressive, or progressive course, including based on spring dimensions and spring arrangement – stacks, multiple layers (spring columns), and combinations.
The characteristic or column length can be varied by a large number of possible combinations of the individual disc springs within wide limits. Several conventional disc springs can be replaced by one more powerful HÄUSSERMANN disc spring: more power for more space.
Thanks to the higher power density, the dimensions of the disc springs and the whole component can be reduced, allowing new engineering freedom to be used.
Static use (storage of potential energy) and dynamic use with vibratory stresses. Long service life under dynamic load (when properly dimensioned).

Concentric force transmission due to the rotationally symmetrical shape. High-end quality with high-quality materials. Customized design, tailored solutions.
Special sizes and developments. Better use of space than with other spring types, large spring force with low spring travel. No readjustment under permissible stresses.
Long service life under extreme conditions and precise compliance with force and dimensional requirements. High inherent damping, especially with multiple layering.
Wide range of applications. Our engineers are on hand for the precise calculation and design; furthermore, you can use our special disc spring Designer App yourself at any time.

VARIANTS, DESIGNS AND PACKAGES

We offer a wide package of customized disc spring solutions and variants for a wide variety of applications.

Single springs with highly precise specifications – optimally adapted to demanding applications.
Disc springs, unslotted or slotted (tongue disc spring): for example, for ball bearings. They ensure backlash-free running and reduce running noises here. Additionally, they contribute to tolerance and play compensation, to compensation of movements and heat-induced changes in length.
We manufacture disc spring columns/assemblies with special properties according to customer specifications and ready for installation.

Flexible design of spring characteristics

Thanks to the geometry of the disc springs, several similar elements can be layered/stacked, and a wide variety of spring characteristics can thus be achieved. The spring rate, force, and spring travel change when stacking disc springs, depending on the combination. It is crucial to guide the disc stack accurately on the inner or outer diameter.

Parallel connection – same-direction disc spring arrangement: The spring forces add up while the spring travel remains constant. The deflection per load unit increases with parallel stacking.
Series connection – alternating disc spring arrangement: The spring travel adds up while the force remains constant. The load per deflection unit increases with series stacking.

Progressive characteristic curves can be achieved when disc springs of different thicknesses are suitably arranged. For this purpose, several disc springs of different material thicknesses or the same disc springs with intermediate rings of different thicknesses or different layering types can be used.

Thanks to various combinations of series and parallel connections, the characteristic curve of a spring stack can be designed extremely flexibly in a large number of variants. HÄUSSERMANN customized disc springs, therefore, provide you with a very wide range of possible applications.

Whether you are looking for performance, reliability, or innovative design possibilities, our Disc Springs are the ultimate choice to meet your needs and surpass expectations.

DISC SPRINGS WITH PARTIALLY HORIZONTAL SPRING CHARACTERISTICS

Our advanced Disc Springs with partially horizontal spring characteristics are designed to deliver outstanding performance across a wide range of applications. These versatile springs ensure exceptional functionality and reliability, offering significant benefits:

Spring pressure can be effectively kept constant over a more or less extended spring travel, ensuring consistent and reliable performance.
Ideal for clearance compensation of moving parts, such as ball bearings, seal packings, and other critical components.
Excellent for expansion compensation due to temperature changes in screw connections and similar systems, ensuring stability even under varying conditions.
Perfect for compensating installation tolerances, which helps to simplify assembly and enhance precision.
Highly efficient in automatic adjustment during wear operations, making them an excellent choice for overload slipping clutches, multi-disc clutches and brakes, disc clutches, and disc brakes.

By using clutches equipped with our customized Disc Spring solutions, you can eliminate the need for adjustment work entirely until the friction linings require replacement. This makes them not only highly reliable but also completely maintenance-free for an extended period.

Discover how our innovative customized Disc Springs can elevate your designs and simplify maintenance while delivering unmatched performance and durability.

DISC SPRINGS WITH PARTIALLY NEGATIVE SPRING CHARACTERISTICS

DISC SPRINGS WITH PARTIALLY NEGATIVE SPRING CHARACTERISTICS
Our advanced customized Disc Springs with partially negative spring characteristics are revolutionizing applications across various industries. One of the most well-known uses for these specialized disc springs is in motor vehicle clutches. At HÄUSSERMANN, we have carried out groundbreaking work in Europe, laying the foundation for the modern and highly successful Disc Spring Clutches used in passenger cars, trucks, and tractors today.

Additionally, these unique customized disc springs play a significant role in continuously variable transmissions, where their partially negative characteristics offer unparalleled advantages.

Key benefits of our customized Disc Spring solutions include:

Lighter pedal work due to reduced disengaging force:
The tongues of the slotted Disc Spring significantly reduce the disengaging force required for a vehicle clutch. Unlike conventional helical compression springs, the force of the disc spring decreases during disengagement, making pedal work noticeably easier and more comfortable.
Adjustment no longer necessary:
With the gradual wear of the friction lining, the spring force of our customized disc springs does not decrease. Instead, it increases, providing a wide range of wear compensation. This unique feature eliminates the need for any manual adjustment of the clutch.
Compact design possibilities:
The smaller overall length of the clutch enabled by the Disc Spring design allows for more space-efficient and innovative engineering solutions.
Rotational symmetry for high-speed reliability:
As a rotationally symmetrical component, the customized Disc Spring does not produce any imbalance. Even at high speeds, it remains stable and effective, unlike traditional coil springs.

Experience the transformative benefits of our advanced customized Disc Springs with partially negative spring characteristics, delivering unmatched performance, reliability, and ease of use in critical automotive and industrial applications.
