ABSTRACT:
A rotational power transmission device 1 has a rotational input shaft 3, rotational input to which is transferred, via a sun gear 4 (the number of teeth is Za) and first planetary gears 5 (Zb), to second planetary gears 6 (Zc). The first and second planetary gears 5, 6 are mounted on a common planetary carrier 7. Planetary shafts 6a of the second planetary gears 6 also support third planetary gears 8 (Zd), and rotation of the second planetary gear 6 is transferred directly to the third planetary gears 8. The rotation of the third planetary gears 8 is transferred via an external gear 9 (Ze) to a rotational output shaft 11. The common planetary carrier 7 can be connected and disconnected to the input shaft 3 by means of a clutch means 12 and a clutch brake 13. The relationship of the numbers of teeth of the respective gears are Za/Zc=Ze/Zd, the normal and reverse rotations at an equal speed can be obtained from the output shaft 11.
