Planetary gear type transmission for actuating device for operating e.g. wiper of vehicle, sets difference in number of teeth of ring gear to correspond with difference in number of planet gear

摘要

The planetary transmission (40) has a pair of planet gears (30,32) that is rotatably and fixedly connected to one another and mounted on a planet carrier (34). The planet gears mesh with respect to the ring gears (36,38) respectively. The difference in the number of teeth of the ring gear (ZH1,ZH2) corresponds to the difference in the number of planet gear.
