Description
Definition
The Variator Shaft, part number 670201 for Claas, is a genuine OEM component that functions as the primary mechanical drive shaft for the header’s reel. It is a key part of the hydraulic or mechanical variator system, which allows for the continuous adjustment of the reel speed. This shaft is engineered to transmit high torque and is designed with specific splines or keyways on its ends to ensure a perfect connection to both the power source (the variator unit) and the reel’s drive mechanism on compatible Claas combine headers.
Function and Role
-
Power Transmission for the Reel: Its core function is to directly transmit rotational power from the machine’s variator drive unit to the header’s reel. This provides the necessary force to rotate the reel, enabling it to perform its critical tasks of gathering and guiding crop into the cutterbar.
-
Enabling Operational Adjustment: As the central link in the reel drive system, this shaft is essential for enabling the operator to vary the reel speed. As the variator unit adjusts the output speed, this shaft directly transfers that change to the reel, allowing it to be synchronized with the ground speed for optimal crop feeding in varying conditions.
-
Ensuring Drive System Integrity: The shaft’s robust construction and precise fit are crucial for the reliability of the entire reel drive system. It must withstand significant torsional forces and shock loads without failing. A damaged or broken variator shaft would immediately disable the reel, leading to poor crop feeding, increased harvest losses, and operational downtime.
