An Idler Gear Woodruff Key helps to secure the idler gear to the shaft and maintain accurate synchronization between the crankshaft and camshaft. The Woodruff Key used for the idler gear is semicircular with a flat bottom and a rounded top. This shape enables it to fit into a machined keyway on both the idler gear and the shaft.Attributes:• Provide a secure fit and prevent rotational movement or slippage• Enables the transmission of rotational motion, allowing the idler gear to rotate synchronously with the crankshaft and camshaft, ensuring proper valve timing• Fit securely into the keyway without excessive play or tightnessApplications:An Idler Gear Woodruff Key is used to ensure that the Idler gear remains securely attached to the shaft, preventing any timing discrepancies or misalignment during engine operation.
