SOLUTION: The number of teeth of ring gears 41 and 42, and those of normal module, normal pressure angle, twisting angle, pitch circular radius, basic semidiameter, tooth bottom diameter, tooth top diameter, tooth depth, dedendum, addendum, lead, normal addendum modification coefficient and circular tooth thickness in two planetary gear mechanisms 36 and 38, where the ratios of the number of teeth of two sun gears 37, 39 and that of ring gears 41 and 42 are different from each other, are all made into the same respectively. In addition, at least those of circular tooth thickness, normal angle addendum modification coefficient, dedendum, addendum, tooth depth, twisting angle, normal pressure angle, and normal module of two pinions 43 and 44 of these two planetary gear mechanisms 36 and 38 are made the same respectively. With this constitution, tools required for cutting work of the ring gears 41 and 42 are jointly usable, so that promotion of inexpensiveness in equipment cost is made achievable.

摘要： PROBLEM TO BE SOLVED: To prevent any transfer of the axial vibration of an output member to a planetary gear mechanism by installing a first connecting means, unifying those of connected elements themselves in one direction of the axial directions, and also a second connecting means connecting the connected element and an output member free of relative movements in the axial direction. SOLUTION: A carrier cover 41 of a third planetary gear mechanism 21 installs a recess part 43 and a projection part 44 on the whole circumference, and likewise a recess part 45 and a projection part 46 are alternately installed on the whole circumference at the end at the side of the carrier cover 41 in a ring gear 25, and the projection part 46 is inserted into the recess part 43 and the projection part 44 into the recess part 45, respectively. With this, the ring gear 25 and the carrier cover 41 are unified as one body in the circumferential direction with an axis B as the center, turning to a first connecting means. In addition, a recess part 48 and a projection part 49 are alternately installed on the whole circumference at the side end of the ring gear 25 in a connecting drum 35, and the projection part 44 is inserted into this recess part 48. With this, the carrier cover 41 and the connecting drum 35 are connected to each other free of relative movement in the axial B direction, turning to a second connecting means. Therefore an axial vibration of the output member is absorbable with the second connecting member.

摘要： PURPOSE:To eliminate thrust force occurring in compound planet gears so as to obtain always a good intermeshing state by providing mutual eequivalence in twist directions of respective intermeshing teeth and leads of large diameter and small diameter pinions. CONSTITUTION:In each planetary gear 10, a sun gear 14 is disposed concentrically with the center line, and it is spline fitted to a motor shaft 12, and its position in axial direction is then regulated by a carrier 16 through thrust bearings 30, 32. A large diameter pinion 26 intermeshes to the sun gear 14, and a small diameter pinion 28 intermeshes to a ring gear 24. In this case, both pinions 26, 28 are left twisted in their intermeshing teeth and are some mutually same in leads. Accordingly, plural compound planet gears 20 are able to move independently in their axial directions. And thus, proper intermeshing state can be easily obtained, and also thrust forces occurring in the pinions 26, 28 due to the twist of intermeshing teeth are mutually opposite in orientation and are similar in their magnitudes. So, overall thrust force in the compound planet gears 20 becomes almost 'zero' and thus load in the carrier 16 is reduced.
