A transmission includes a ring member (220), a sun member (210), a number of planetary sheaves (230, 232, 234) and a serpentine drive member (222) which wraps around the sun member, and the planetary sheaves. The planetary sheaves are attached to a planet carrier (240) at a distance from the sun member. When the serpentine drive member is wrapped around the sun member and the planetary sheaves, the serpentine drive member forms a C-shape. The transmission can be used in a drive that has an input shaft (110) that must be rotated at a first speed and an output (120) shaft that must be rotated at a second speed. The transmission can even be used as a reverser. The serpentine drive member (222) can be any type of drive member, including a timing belt with teeth, a flat belt, a cable chain, or a link chain. |
