ABSTRACT:
A zero velocity gear mesh differential is disclosed. A power input shaft and a power output shaft are colinear and tend to rotate at the same speed. Power gears effect the transfer of power. In addition, there are speed control gears including a planetary system having a control carrier and a sun gear. A plurality of planet gears engage said sun gear and also engage an internal ring gear integral with an external worm gear and which is supported by the control carrier and planet gears. The external worm gear is engaged by a worm which is rotatable. A fixed gear on the control carrier engages a fixed gear on the main carrier.
