摘要： Five receiving holes 2e extending along the axis of a circular cylindrical portion 2b of a housing are formed in the circular cylindrical portion 2b. Those five receiving holes 2e are arranged at equal intervals in the peripheral direction of the circular cylindrical portion 2b. Each receiving hole 2e rotatably receives therein a planetary gear 5. The respective planetary gears 5 are in engagement with an inner gear 3 and a sun gear 4. The teeth of the inner gear 3, the sun gear 4 and the planetary gears 5 are helical teeth. The numbers of teeth of the inner gear 3, the sun gear 4 and the planetary gears 5 are set to 36, 24 and 6, respectively. As a result, the numbers of teeth of the inner gear 3 and the sun gear 4 located between adjacent two planetary gears 5 in the peripheral direction become 7.2 and 4.8, respectively, which are values each having a fraction below the decimal point.

摘要： A planetary gear 5 is contacted at its at least one tooth of all its teeth 51n with an end edge 23d facing an inner releasing part 23c of an inner peripheral surface of a receiving hole 23a irrespective of a rotational position of the planetary gear 5. By doing so, the planetary gear 5 is prevented from moving in the radial direction. As a result, the planetary gear 5 can be prevented from vibrating in the radial direction. Thus, vibrations of a planetary gear apparatus can be reduced, and the planetary gear and a carrier can be reduced in damage.

摘要： An internal gear 10 is rotatably received within a housing 8 (planetary carrier 2 and case 4), and a sun gear 12 is rotatably disposed on a circle located inside of and concentric with the internal gear 10. Planet gears 14 which are carried within carrying openings 2c formed in a planetary carrier 2 are disposed between the internal gear 10 and the sun gear 12 in meshing engagement with the internal gear 10 and the sun gear 12. The internal gear 10, the sun gear 12 and the planet gears 14 each have spherical gear teeth, and develops a thrust upon occurrence of a relative rotation therebetween. A coupling 16 is connected to the inner periphery of the internal gear 10 through helical splines 10d and 16a for purpose of power transmission. The helical splines provide a novel thrust generating mechanism, which enlarges the extent in which a bias ratio can be adjusted.
