Drehfedern

Drehfedern, also known as helical springs, are mechanical components designed to store and release energy through rotational motion. They consist of a cylindrical coil of wire wound around a central axis, which allows for a compact and efficient design. The primary function of a Drehfeder is to exert a torque or rotational force, making them ideal for applications requiring controlled rotational movement.

Drehfedern are commonly used in various industries, including automotive, aerospace, and machinery. In the automotive sector, they are often found in power steering systems, where they assist the driver by reducing the effort required to turn the steering wheel. In aerospace, Drehfedern are used in control mechanisms for aircraft surfaces, such as ailerons and rudders, to ensure precise and smooth movement. In machinery, they are employed in applications like conveyor systems and rotating equipment to provide the necessary torque for operation.

The design of a Drehfeder involves several key parameters, including the wire diameter, coil diameter, number of active coils, and material properties. These factors influence the spring's stiffness, load capacity, and fatigue life. Common materials for Drehfedern include music wire, stainless steel, and high-strength alloys, each offering different advantages in terms of strength, corrosion resistance, and cost.

Drehfedern are valued for their reliability, durability, and ability to provide consistent torque over a wide range of rotational angles. They are often preferred over other types of rotational springs due to their compact size, ease of integration, and ability to withstand high loads and cyclic stress. Proper selection and installation of Drehfedern are crucial to ensure optimal performance and longevity in various applications.
