<P>PROBLEM TO BE SOLVED: To provide a compact planetary gear mechanism that increases the deceleration ratio without increasing the number of teeth of gears. <P>SOLUTION: In this planetary gear mechanism 1, a sun gear 91 as an input gear receives a smaller load than an internally toothed output gear 45, so that the gears (second planet gears 95) having a smaller module are connected to planet gears 93, and the sun gear 91 is in engagement with the second planet gears 95. The sun gear 91 is formed of the same module as the second planet gears 95. The rotation of the sun gear 91 is reduced in speed and transmitted to the second planet gears 95, and rotation of the second planet gears 95 rotated at a reduced speed is further reduced in speed based on the slight difference in the numbers of teeth of a ring gear 44 and the internally toothed output gear 45 for output. <P>COPYRIGHT: (C)2012,JPO&INPIT |
