levyliitin

Levyliitin is a Finnish term that translates to "disk coupling" or "plate coupling" in English. It refers to a type of mechanical coupling used to connect two rotating shafts. The fundamental principle of a levyliitin involves a flat, circular disk or plate that is rigidly attached to each of the shafts it connects. These disks are then joined together, typically by bolts or pins, creating a direct and fixed connection between the two rotating elements.

The primary function of a levyliitin is to transmit torque from one shaft to another without any degree of flexibility or damping. This means that any misalignment between the connected shafts will be directly transferred to the driven shaft, which can lead to increased wear and vibration if not properly accounted for during installation. Due to their rigid nature, levyliittimet are best suited for applications where precise shaft alignment is achievable and maintained.

Levyliittimet are often employed in machinery where simplicity and a direct power transfer are prioritized. They are common in applications such as agricultural machinery, simple pump drives, and various industrial equipment where torsional rigidity is a key requirement. The design is relatively straightforward, making them cost-effective and easy to manufacture. Maintenance is generally minimal, provided the shafts remain properly aligned. While they offer a robust connection, their lack of flexibility makes them unsuitable for applications experiencing significant shaft misalignment or requiring vibration isolation.
