Keys, Cotter Joints, Pin Joints

Chapter Outline

 

Key, cotter, and pin are employed as temporary fasteners to join two components to transmit motion and forces from one element to another. Perhaps the most common of these motion-transmitting connections are keys. Keys are usually driven parallel to the axis of the shaft that are subjected to torsional motion. Cotters are normally driven at right angles to the axes of the connected parts.
