Development of Optimal Transmission Rate of the Kinematic Chain by using Genetic Algorithms Coded in Mathcad

Abstract

Part of machine element, require time to design, to calculate and to produce it. Production of helical gears passes through these processes. In this article is considered that production of these gears was made by milling machine. The goal is to minimize the time that needed to calculate the kinematic chain that is used to create the helical profile of gear. Kinematic chain contains the gears train with given set gears of the milling machine that mounted between driven shaft and raw part. Gear train usually is with two or three steps. An optimization algorithm will be used to find the correct tooth numbers of the gears train that gives the required transmission rate with acceptable accuracy. Genetic algorithm (GA) method has been used to find the optimal solution where the numbers of the teeth were variables and the transmission rate was the objective function.
