ROTATIONAL DRIVE FORCE TRANSMISSION APPARATUS

WIPO Patent Application WO/2011/065466

A1

Provided is a rotational drive force transmission apparatus which is capable of reducing load with respect to an input means such as a motor and decreasing the energy required for the input of, for example, electrical power to be consumed, thereby improving output efficiency. The rotational drive force transmission apparatus is provided with an input shaft (6) which has an input gear (8), and an output shaft (6a) which is supported so as to be coaxial with the input shaft (6). The input gear (8) rotatably drives a driven gear (12) integrated with a pair of internal gears (11) that internally mesh with a stationary inner gear (10). The gear shafts of the internal gears (11) are supported at a short rotary arm (14) provided with a drive bevel gear (15). A rotary drive force, which is transmitted from the drive bevel gear (15) through a plurality of bevel gears to a first intermediate gear (28), may be transmitted by way of two intermediate gears to a stationary gear (33) which does not rotate. The upper and lower positions of an intermediate gear (31), which is one of two intermediate gears located between the first intermediate gear (28) and the stationary gear (33) and which engages with the first intermediate gear (28), do not change when the input shaft (6) and the output shaft (6a) thereof revolve as shafts.
