Parallel key, one round end, tapped and counterbored
Choose a method
From torqueFor when the torque on the shaft is already fixed. From the width, the key length, the shaft diameter, the tapped hole diameter, the number and diameter of the counterbores and the torque it finds the area in shear, the shear force and the shear stress.From the tangential forceFor when the force on the key is already fixed. From the width, the key length, the tapped hole diameter, the number and diameter of the counterbores and the shear force it finds the area in shear and the shear stress. The shaft diameter and the torque are not needed.
