Abstract
There are disclosed in the present specification a plurality of planetary differential drive formats, both simple and compound, in which each drive pair or couple comprises a driving and a driven element interconnected by a flexible connector such as a roller chain or a cogged belt and at least one driving and one driven element are mounted for planetary motion about the input and output axis.

A differential planetary drive assembly comprising means defining a primary axis, means defining a secondary axis, a rotatable external planetary carrier journalled about the primary axis for supporting the secondary axis for movement about the primary axis, a power path comprising a first couple including a driving toothed wheel on the primary axis, a driven toothed wheel on the secondary axis and a complementary flexible connector linking the driving and driven wheels and a second couple including a second driving toothed wheel on the secondary axis, a second driven toothed wheel on the primary axis and a complementary flexible connector linking the second driving and driven wheels.
A differential planetary drive assembly comprising means defining a primary axis, means defining a secondary axis, means defining a tertiary axis, a rotatable external planetary carrier journalled about the primary axis for supporting the secondary and tertiary axes for movement about the primary axis, a first couple including a driving toothed wheel on the primary axis, a driven toothed wheel on the secondary axis and a complementary flexible connector linking the driving and driven wheels, a second couple including a second driving toothed wheel on the secondary axis, a second driven toothed wheel on the tertiary axis and a complementary flexible connector linking the second driving and driven wheels and a third couple including a third driving toothed wheel on the tertiary axis, a third driven toothed wheel on the primary axis and a complementary flexible connector linking the third driving and driven wheels.
