Woodruffnøkler

Woodruffnøkler are specialized mechanical components used to secure rotating parts on shafts, primarily in machinery and engineering applications. They are a type of key, designed to transmit torque between a shaft and a mounted component such as a gear, pulley, or coupling. The unique feature of a Woodruffnøkkel is its semi-circular, crescent shape, which allows it to sit in a corresponding slot cut into both the shaft and the hub of the attached part.

This design offers several advantages. The curved profile of the Woodruffnøkkel provides a full and even contact surface, which reduces stress concentrations and minimizes wear over time. Additionally, the shape allows for easier assembly and disassembly compared to rectangular keys, as it can be inserted from the side without requiring the removal of the entire shaft or component. These keys are typically made from durable materials such as steel or other high-strength alloys, ensuring reliable torque transfer and long service life.

Woodruffnøkler are used in various industries, from automotive to industrial machinery. They are often employed in situations where space constraints or ease of assembly are critical factors. The installation involves machining a specific, semi-circular keyway into the shaft and hub, after which the key can be inserted and secured with a set screw or other locking mechanisms.

Overall, Woodruffnøkler are valued for their efficiency in torque transmission, ease of installation, and ability to distribute stresses uniformly, making them a common choice in precision mechanical assemblies.
