koppelbegrenzers

A koppelbegrenzer, or torque limiter, is a mechanical device designed to protect machinery from damage caused by overloads or sudden jams. It functions by interrupting the power transmission when the rotational force, or torque, exceeds a predetermined safe limit. This prevents components such as gears, shafts, and motors from being subjected to excessive stress, which could lead to breakage or failure.

There are several common types of koppelbegrenzers. Friction-based limiters utilize friction plates that slip when the torque limit is reached, allowing the input and output shafts to rotate at different speeds for a short period. Shear pin or bolt type limiters employ a pin or bolt designed to break when the torque exceeds a set value, effectively disconnecting the driving and driven components. Other types include ball-and-ramp mechanisms and electronic sensors that can monitor torque and signal a shutdown.

Koppelbegrenzers are crucial safety components in a wide range of industrial applications. They are found in conveyor systems, agricultural machinery, packaging equipment, machine tools, and automotive drivetrains. By acting as a sacrificial element or a controlled slip mechanism, they absorb shock loads and prevent catastrophic failures, thereby reducing downtime and repair costs. The selection of an appropriate koppelbegrenzer depends on factors such as the required torque capacity, operating speed, and the type of overload protection needed.
