The choice of motor, coupling, keys and bearing mainly through the lookup table and bine with other parts of coordination and asked subjects to choose, and then the motion parameters and dynamic parameters is calculated. In gear was introduced in detail in the design of the gear material selection and determination of allowable stress, calculate and determine the gear parameters is designed according to the tooth root bending fatigue strength and main dimensions. Followed by designing of shaft, and determine the size of the ladder shaft, the shaft, bearing, key and coupling for checking. Finally it has carried on the design to the shape of the reducer. Application of Solidworks software modeling technology, realizing the threedimensional modelling and main reducer parts modeling, to plete the 3 d modeling of the machine, for the structure of transmission system design provides valuable parameter basis.
