For a given driver gear torque, the driven gear in an internal Genevea gear mechanism develops a higher torque than the driven gear in an external Geneva mechanism. This is due to the gear pitch radius differences in both gears under these applications. In both cases however, although the driver gear may have a constant rotational speed, the driven gear has smooth acceleration and deceleration curves because the driver engages the driven gear along an axis aimed at the center of the driven gear, moves on to reach a maximum perpendicular direction at the middle of the motion and then slows down as it disengages along the same axis aimed at the center of the driven gear.--Casperbum (talk) 13:23, 27 August 2012 (UTC)
