A splined shaft refers to a type of mechanical component that features grooves, known as splines, along its length. These splines enable the shaft to fit securely within a corresponding hole or opening in another part, providing both rotational and axial movement with minimal play or wobble. Splined shafts are commonly used in various applications, such as transmissions, gears, and machinery components, to transmit torque and maintain alignment between connected parts.
