Feather key for Wirtgen 2200SM

The feather key, identified by part number 120997, serves as a mechanical interface within the power transmission system of the Wirtgen 2200SM milling machine. By seating into machined slots on both the shaft and the attached component, such as a gear, pulley, or pinion, this component facilitates the transfer of rotational torque while preventing slippage between the connected parts.

This component is designed for specific integration within the Wirtgen 2200SM milling machine. It is engineered to maintain precise tolerances to ensure a secure fit within the assembly, which is necessary for the consistent operation of the machine's drivetrain. Proper installation and alignment are required to manage the shear forces encountered during the milling process.

Feather keys function as a locking mechanism in rotating assemblies, providing a positive connection that allows for the transmission of power from a drive shaft to a driven element. They are designed to withstand the stress of torque loads and are critical for maintaining the synchronization of the mechanical system. Regular inspection of the key and its corresponding keyway is common practice to ensure that the connection remains tight and free from excessive play, which can otherwise lead to mechanical inefficiency or component wear.
