How backlash affects gears SDPSI

    where: j = linear backlash measured along the pitch circle (Figure 142(b)) s std = no backlash tooth thickness on the operating pitch circle, which is the standard tooth thickness for ideal gears s act = actual tooth thickness When the center distance is increased by a relatively small amount, Δa, a backlash space develops between mating teeth, as in Figure 143.
