A variable speed drive apparatus having a pair of bevel pinions connecting a pair of bevel gears, the bevel pinions being mounted in a cage able to rotate independently of the bevel gears, which are connected to an input shaft and an output shaft. The rotational speed of the output shaft is monitored and is decreased if needed by retarding rotation of the cage in response to a higher than desired rate of rotation of the input shaft.
