Adriver can determine the actuator (planetary) movement, driver is usually the center wheel or tied; that is in direct contact with the planet gear center wheel ortied as a driving member drives the planetary gear, a planetary wheel itselfaround the axis of rotation of the O1-O1, on the other hand, along with the component H (or tied) rotation about a fixed axis (O-O axis rotary center wheel). Planetary gear train and a differential gear system called epicyclic gear trains (anepicyclic gear train is composed of three types of component 1 a tie. The 2 one or several planetary wheel. Center wheel 3 or a few and the planetary wheel meshed.). Planetary gear train, two center wheel has a fixed; differential gear train, the twocenter wheel can be moved (i.e. F=2). It has the features of compact structure, small volume, small mass, large bearing capacity, high, range of power and transmission range transfer operation low noise, high efficiency and long service life etc.. Mainly used in machinery,metallurgy, national defense, mine hoisting and transportation, chemical, textile,building industry and other departments of the. The main content of this paper is based on the NGW type planetary gear reducer, the force generating gear contact, and 3D modeling with
