Generally divided into basic transmission friction type, chain and belt type and pulsating flow. By selecting device inside the different parameters, which can realize precise control of motor speed and expand the basic transmission capacity, and expand the basic transmission speed range, and even realize zero speed. The basic transmission and the differential gear train, to improve the transmission speed range, as a result, the differential transmission has the very good development space and market prospects. According to the analysis of the differential transmission and design of more complex problems, put forward a kind of differential gear train was carried out on the differential transmission of gear calculation method, and combined with the transmission assembly design method, gives the detailed design process of a differential transmission, and draw the assembly drawing, according to the parameters of the same type transmission design provides a theoretical basis and methods. By analyzing the differential stepless transmission belt type CVT working principle, the differential stepless transmission pulley transmission and the differential gear train and in the calculation and design of fixed axis gear pair, the pulley gear transmission of the important parameters, finally the combination assembly design, realized the stepless transmission speed range.
