Abstract
This invention features the concept of packaging a transmission so that it can be selectively embodied in any drive system as a unitary structure and serve per se, if desired, as the hub of a rotary drive element. A distinctive feature of this package is that the housing of the transmission unit serves as an output element. A preferred embodiment of the above described concept incorporates details of an output speed-controlled transmission comprising an input shaft, an output shaft and adjustable drive means by which said input shaft drives said output shaft and is characterized by means responsive to the rotational speed of the output shaft to adjust the drive means so as to maintain a predetermined rotational speed condition of the input shaft.
