Feather key connection

A keyway connection consists of a keyway in the shaft and a matching key that is inserted into the keyway. The key transmits the torque between the shaft and hub through positive contact. By selecting the correct key size and shape, the connection can be adapted to the specific load requirements.

Different types of feather keys

There are various types of feather keys, including straight feather keys, wedge or trapezoidal feather keys and disc springs, each of which is suitable for different applications and loads. The choice of type depends on factors such as torque transmission, space requirements and mechanical properties of the components to be connected.

Materials and designs for feather keys

Parallel keys are typically made of steel or stainless steel to ensure high strength and wear resistance. They are available in various dimensions and designs to meet the requirements of different mechanical engineering applications.

Areas of application and significance in practice

Parallel key connections are widely used in various areas of mechanical engineering, including transmission technology, pumps, generators, drive systems and machine tools. They are particularly useful in applications that require precise and reliable power transmission.

Assembly and maintenance of feather key connections

The installation and regular maintenance of keyway connections requires precise machining of the keyways and careful assembly to ensure a secure and reliable long-term connection. Periodic inspections are important in order to detect and rectify wear or loosening at an early stage.
