Gib and Cotter Joint

grabcad

The gib and cotter joint in a connecting rod's strap end serves as an effective solution to prevent the strap from spreading outwards due to frictional forces between the cotter and slot ends. By using gibs alongside the cotter, the friction is minimized as they increase the cotter's sliding surface, thus reducing the tendency of the cotter to slacken back. Additionally, gibs allow for parallel holes to be utilized, providing better stability and functionality in the joint.
