Abstract

With the rapid development of modern industry in China,the application of the mechanical stepless transmission is range. Adopts stepless transmission, especially with reduction drive which can further enlarge its range of variable speed and output torque, it also can better adapt to the working condition of mechanical requirements，make the efficiency of the best. As in improving yield and quality of products, meet the needs of variable speed, save energy and realize mechanization, automation and so on various aspects of the whole system, it has significant effect. So the stepless transmission has become a basic universal transmission type, used in textile, light industry, food, packaging, chemicals, machine tools, lifting the transport, mining, metallurgy, engineering, agriculture, national defence and test and other kinds of machinery, it has developed various types and has set up a series production. Thus it can be seen, the research in the field of overloading stepless transmission has important significance to the development of heavy industry in our country.

The features of the transmission that we designed are: double input, single output, planetary gears by mechanical coupling to adjust one of the small power input to the output adjustment, which can play, and reduce the cost, save energy and cost effect, is a kind of planet type stepless transmission used for the field of overloading.

This article mainly introduced the overview of mechanical planetary stepless transmission and its solution, the selection of transmission main parameters and the design of main parts, the strength calculation of gears with the material selection, strength calculation and checking of the transmission shaft.

Keywords: power confluence planetary stepless transmission structure design
