A Woodruff Key evenly distributes the torque or rotational forces between the shaft and the driven part. This is to prevent localized stress concentrations and ensures a more uniform load distribution, enhancing the overall strength and reliability of the connection. It provides axial retention, preventing the driven part from sliding off the shaft during operation.Attributes:• Withstand high torque and axial loads• Ensure efficient power transmission without slippage or loss of torqueApplications:A Woodruff Key securely connects the piston to the crankshaft, ensuring that the rotational motion of the crankshaft is transferred to the piston.
