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： In a differential gear system disclosed, a pair of sun gears and a plurality of pairs of planetary gears are received in a housing. The pair of sun gears are coaxial with a rotational axis of the housing. End portions of a pair of drive shafts extending through a pair of end walls of the housing are spline-engaged respectively with the pair of sun gears. The pair of sun gears have helical teeth, respectively. Each pair of intermeshing planetary gears are meshed respectively with the helical teeth of the pair of sun gears, respectively. A plurality of washers are interposed between the pair of sun gears. The plurality of washers have first washers and second washers, respectively, which first and second washers are alternately arranged. The first washers are engaged with end portions of reduced diameters of the sun gears such that the first washers are capable of moving axially but incapable of rotation. The second washers are engaged with the housing such that the second washers are capable of moving axially but incapable of rotation.

摘要： A receiving portion 2e for rotatably receiving therein a planetary gear 3, is formed between a plurality of retaining protrusions 2d of a carrier. A connection portion 2f extending annularly about a rotation axis L is formed on an outer peripheral of a distal end portion of each retaining protrusion 2d. Through this connection portion 2f, the distal end portions of the respective retaining protrusions 2d are connected to each other. Owing to this arrangement, each retaining protrusion 2d is reinforced to minimize its deformation. As a result, deformation of the receiving portion 2e is greatly reduced and the planetary gear 3 receiving in the receiving portion 2e can rotate smoothly.
