Numerical model of mechanical stepped speed changing system plan

Abstract：First, multiplication and addition of series is defined, and combining rotate speed chart and drive system chart of numerical model of mechanical stepped speed changing system, numerical model of mechanical stepped speed changing system plan is built up. With the numerical model computer aided design and optimization from the plan to the calculation of structure, dimension can be realized and technical problems of plan design with the computer can be solved. Numerical model put forward in this paper contains all content what rotate speed chart expresses easily and perspicuously. Through the up_building of numeral model of general drive system, embranchment drive system and drive system of multi_speed, induces the characteristic of numeral model of different type of drive system, which establishes the base for optimization design using numeral model.
