Abstract: The constituents of constructional elements and the interconnection
of design for drive systems of various general reducers are analysed.The
main idea for their design sy nthesis is presented.The synthetic program
counting with computer suitable for them is made up,The adopted BASIC
source progra m has been practiced, proved and passed in IBM computer,It
can be used to design the drive systems for general reducers that consist
of involute cylinder gears,point contact helical gears，bevel gears，worm
drive a nd V-belt drive respecsively.It can still make continuous calcula-
lions of a lot of plans for the same type of reducers, It has the charac-
teristics of synthesis, elasticity, self-adjustment，practicality of higher
efficiency, wider application and simple usage
