In the given diagram, identify the maximum value of addendum radius of the larger gear or the wheel to avoid interference.

In the given diagram, identify the maximum value of addendum radius of the larger gear or the wheel to avoid interference. Correct Answer BE

BE is the maximum value of addendum radius of the wheel or the larger gear to avoid interference of the gears. It is given by Ra max. When two gears are in mesh at one instant there is a chance to mate involute portion with non involute portion of mating gear. This phenomenon is described as interference. In case of a pinion, AF is the maximum value of the addendum radius of the pinion.
