Rotationsdämpfer

Rotationsdämpfer, also known as rotary dampers or dashpots, are mechanical devices designed to control or reduce rotational speed and absorb rotational energy. They achieve this by creating resistance to motion, typically through the use of a viscous fluid or a friction mechanism. When a shaft within the damper rotates, it moves a vane or piston through a fluid-filled chamber or engages a friction element, generating a damping torque. This torque opposes the rotation, slowing it down smoothly and preventing sudden, jerky movements.

The primary function of a rotationsdämpfer is to provide a controlled deceleration or to eliminate unwanted oscillations in rotating systems. They are commonly employed in applications where a smooth and quiet operation is desired, or where the impact of sudden stops needs to be mitigated. Examples include the closing of appliance doors such as refrigerators and dishwashers, lids on cabinets, and even in automotive applications for controlling the movement of certain components.

There are several types of rotationsdämpfer, with fluid-filled designs being the most prevalent. These can utilize silicone oil or other viscous fluids, with the viscosity of the fluid determining the damping force. The viscosity can be selected to match the specific application requirements. Friction-based dampers, while less common, rely on the resistance between surfaces to achieve damping. Rotationsdämpfer are valued for their simplicity, reliability, and the ability to enhance user experience by providing a more comfortable and controlled operation of mechanical systems.
