A NEW ITERATIVE ALGORITHM FOR KINEMATIC SYNTHESIS OF GEAR DRIVES FOR OPTIMAL SPEED RATIO

The double composite gear trains offer attractive design features. How ever, their analysis using the algebraic equations method involves len gthy and tedious manual manipulations. The existing theories of compos ite gear trains is useful in this process to some extent, but it will not facilitate development of an algorithm suitable for all kinematic versions of a drive. The present algorithm based on the Unified Theory has been used for analysis of all the 18 versions of the drive with s imilar structure. The input data is simplified to that of feeding valu es of index exponents for the applicable versions. The optimal version of the twelve speed drive is synthesized with the present algorithm f rom the 18 versions belonging to open type having similar structure.
