A differential speed transmission for varying the rotational speed of an input shaft relative to an output shaft wherein the differential speed transmission is characterized by: a pair of opposed first stage face gears each having a second stage pinion gear co-rotating therewith, a first stage input pinion disposed between and engaging each of the face gears to effect counter-rotation of the face gears and the second stage pinions, and a second stage face gear engaging each of the second stage pinions for driving the output shaft. In one embodiment of the invention, the second stage face gear circumscribes a portion of the first stage face gears and a base portion of said output shaft envelopes a portion of the first stage face gears. This arrangement permits large speed differentials within a small, compact design envelop. In another embodiment, the differential speed transmission permits alignment of the face gear pair about a common axis to effect equal torque distribution. One embodiment permits self-adjustment of the face gear pair and another embodiment permits independent manual adjustment of each.
