Force limiter with Disc Spring
Apr 27, 2026
In a force limiter, disc spring stack plays a critical role in ensuring precise and reliable system performance.
Disc springs provide an axial preload that keeps the locking segments firmly pressed against the conical surface.
As the external force increases, disc springs are further compressed. When the force approaches the defined disengagement force, the locking segments begin to show a tendency to loosen.
Once this threshold is reached, disc springs compress to their critical point, forcing the locking segments outward from the conical surface. As a result, the system disengages instantly, and the locking segments detach from their grooves.
At this stage, disc springs are in a state of maximum compression, and the system stops transmitting force, thereby protecting the equipment.
Features of disc Springs in the force limiter
- Defined and Adjustable Release Force: Disc springs generate the preload that determines the exact release force. By adjusting the number or arrangement of the springs, the release force can be accurately set to meet specific application requirements.
- Energy Storage and Fast Disengagement: Disc Springs stack stores elastic energy during operation. Once the force reaches the defined threshold, this energy is released instantly, enabling a quick and reliable disengagement to protect the equipment.
Force limiter is used for overload protection.
