Abstract
Gearing is one of the most effective methods for transmitting power and rotary motion from the source to its application with or without change of speed or direction. Gears are mostly used to transmit torque and angular velocity from one shaft to another shaft. The less efficiency of gear box of a machine tool is a serious problem as it increases maintenance cost and also affects the reputation of a firm. Hence its life has to be increased and should be made more reliable. Optimization plays an important role in gear design as reducing the weight or volume of a gear set will increase its service life and improve the bearing capacity. The method of optimum design is effective in the field of gear research to determine the optimum gear parameters for satisfactory design. In gear design, number of parameters is involved. The gear design also requires an iterative approach to optimize the gear parameters. The alternative for the above problem is to design and optimization of a worm gear box which reduced maintenance and improved reliability, lack of lubrication requirements, precise peak torque transmission, inherent overload protection, physically isolated input and output shafts, misalignment tolerance, and low acoustic noise and vibration etc. And also it is multi-objective function with constraints is very difficult to optimize using conventional optimization techniques, used non-traditional optimization technique called Genetic algorithm. Genetic Algorithm is used for determining the best possible combination of gear parameters. A review of relevant literature in the areas of optimized design of gear indicates that compact design of gears involves a complicated algebraic analysis.
