Dubbelkopplingsväxellåda

Dubbelkoppling, often translated as double coupling, is a mechanical term referring to a connection between two rotating shafts designed to transmit torque. Unlike a single coupling that connects two shafts end-to-end, a dubbelkoppling typically involves an intermediary component or a more complex arrangement that allows for a greater degree of flexibility or specific power transmission characteristics. These couplings are crucial in various engineering applications to connect a power source, such as an electric motor or an engine, to a driven machine, like a pump or a conveyor belt.

The design of a dubbelkoppling can vary significantly depending on its intended use. Some types incorporate flexible elements, such as rubber or spring components, to absorb shock and vibration, thereby protecting the connected machinery from torsional stress and misalignment. Other designs might involve gears or sliding mechanisms to accommodate axial, radial, or angular displacement between the shafts. This ability to compensate for imperfections in shaft alignment is a key advantage of dubbelkoppelings, leading to reduced wear and tear on bearings and seals, and ultimately, a longer operational lifespan for the equipment. The choice of dubbelkoppling depends on factors like the required torque capacity, operating speed, environmental conditions, and the degree of shaft misalignment that needs to be accommodated.
