DIN 6888 Woodruff Keys

A key is a metal fastener that secures a pulley, gear wheel, or other component onto a shaft. DIN 6888 Woodruff keys correspond to GOST 24071-80 and ISO 3912. Parallel keys are used in high-stress connections. Woodruff keys also create a stress moment, but their working location is shaft keyways, where they are fitted deeper and more securely. If one key is not enough, two are installed at a certain angle to each other, usually 180 degrees. Woodruff keys are made from A4, A2 stainless steel — the strength of these steels ensures reliable operation of the fastener. Keys are manufactured by special processing of segment profiles. Keyways in hubs and shafts are made by slotting or another method.

Woodruff keys

A key is defined as a metal fastener that secures a pulley, gear wheel, and so on, onto a shaft. DIN 6888 Woodruff keys correspond to GOST 24071-80 and ISO 3912.

Unlike parallel keys, Woodruff keys have a simple design. This type of key is manufactured to high precision, so parts are interchangeable without manual fitting. A Woodruff key is firmly secured in the shaft keyway, which prevents it from skewing, deforming, or working loose. The drawbacks: deep keyways in the shaft reduce its strength, and shortening the key to preserve shaft strength reduces the limit load capacity.

Woodruff keys are used in machinery assemblies and other types of industrial production, as well as in power tools and mechanisms. Assemblies joined with their help are more durable due to the deeper fit of the key in the splines, which strengthens the connection of components. Preparing shaft keyways for this type of fastener is simpler and cheaper.
