![]() ![]() Relative axial movement of the mechanical transmission element is required for functional purposes such as speed reducers and clutches.Mechanical transmission element such as gears and pulleys might need removing from the shaft due to design for manufacture and assembly (DFMA) ie during assembly or to aid manufacturing.They are used mainly for the following reasons. Application of splines and serrationsĪlthough they look like gears, Splines are only used to transmit torque and rotation on the same axis. ![]() Spline shaft bevel gear connectionĪlthough a splined shaft looks like having a series of shaft keyways with keys pushed in, splines are considerably stronger than the keyed joint as the keyways weaken the shaft and reduce its torque carrying capacity. For example, a bevel gear mounted on a shaft might use a male shaft spline that matches the female spline on the gear as shown in Figure 1. Shaft splines and serrations are ridges, or teeth type keys that are an integral part of the shaft that mesh with grooves in a mating hub to transfer torque and rotational motion. ![]()
