“…Additionally, the profile shift has an immense effect on the main operating parameters of gear pairs (working life, efficiency, vibrations, power losses, noise, and wear); it can be used in order to optimize the design, according to the special requirements of each problem. [1][2][3] In recent decades, a variety of methods have been made for determining the profile shift coefficient values in order to satisfy various optimization criteria. In fact, Henriot 4 had proposed a graphical system required for balanced specific sliding in both gears, which reduces wear and heavy scoring risks at the extremes of contact path.…”

Profile shift has an immense effect on the sliding, load capacity, and stability of involute cylindrical gears. Available standards such as ISO/DIS 6336 and BS 436 DIN/3990 currently give the recommendation for the selection of profile shift coefficients. It is, however, very approximate and usually given in the form of implicit graphs or charts. In this article, the optimal selection values of profile shift coefficients for cylindrical involute spur and helical gears are described, using a differential evolution algorithm. The optimization procedure is developed specifically for exact balancing specific sliding coefficients at extremes of contact path and account for gear design constraints. The obtained results are compared with those of standards and research of other authors. They demonstrate the effectiveness and robustness of the applied method. A substantial improvement in balancing specific sliding coefficients is found in this work.

Gears are toothed wheels, transmitting power and motion from one shaft to another by means of successive engagement of teeth. Having a higher degree of reliability, compactness, high velocity ratio and finally able to transmit motion at a very low velocity, gears are gaining importance as the most efficient means for transmitting power. A gearing system is susceptible to problems such as interference, backlash and undercut. The contact portions of tooth profiles that are not conjugate is called interference. Furthermore due to interference and in the absence of undercut, the involute tip or face of the driven gear tends to dig out the non-involute flank of the driver. The response of a spur gear and its wear is an engineering problem that has not been completely overcome yet.With the perspective of overcoming such defects and for increase the efficiency of gearing system, the use of a non-standard spur gear i.e., an asymmetric spur gear having different pressure angles for drive and coast side of the tooth comes into picture. This paper emphasis on the generation of an asymmetric spur gear tooth using modeling software and bending stress at the root of Asymmetric spur gear tooth is estimated by finite element analysis using ANSYS software and results were compared with the standard spur gear tooth.
