Said gear wheel 9 has the number of teeth smaller by one than that of gear wheel 13. Drive rotating multiple outer teeth 13 comprises bearings 11 fitted at the center of flanges of faces 14, 15 of outer gear wheel 13. The latter can be partially knocked down for inner gear wheel 9 to be fitted therein. ^ EFFECT: reduced radial sizes, possibility to fit inner gear wheel into remove from outer gear wheel. ^ 9 cl, 9 dwg |
