Second gear and the 3rd gears meshing, the 3rd geared sleeve is located on output shaft, and the output terminal of output shaft is connected with central shaft, and the output terminal of central shaft is connected with planetary pinion output shaft;
Planetary gear set assembly comprises several planetary gear set be connected in series, driving gear and internal gears;
Each planetary gear set includes driving arm, several planetary pinions and planet axis;
Each planetary pinion engages with internal gear and driving gear simultaneously, and driving gear is set on the output terminal of output shaft;
Planetary pinion is set in planet axis, and planet axis is connected with driving arm, and driving arm serial connection on center shaft; Planet axis and driving arm Spielpassung.
In order to motor vibrations operationally can be effectively reduced, motor is arranged with shock absorbing sleeve.
In order to improve soundproof effect, described sound proof chamber is made up of six pieces of asbestos insulation boards.
The beneficial effects of the utility model are: the utility model is convenient to design and manufacture on the one hand, on the other hand, has possessed the effect of gear drive damping and noise reduction.
