Optimization of Asymmetric Spur Gear Drives for Maximum Bending Strength Using Direct Gear Design Method#

Optimization of asymmetric spur gear drives to improve the bending load capacity

“…All such available earlier studies have only suggested the methods to improve the load carrying capacity of an individual pinion or gear. An attempt has been made by the present authors [12] for the optimization of the pinion and gear of a drive for the balance fillet stresses and also proved successfully with the results of study [5] that the propositions of the gear tooth thickness ratio is equal to the square root of the speed ratio in an optimized gear drive. As a further extension of their study [12], a different approach has been examined in the present study and developed a new non-standard asymmetric rack cutter (here after it is called as non-standard cutter) by considering a standard coast side pressure angle and module, but not through an area of existence method.…”

Computer Simulation of Helical Gears Generated by Rack-Type Cutters

“…Recalling that (13) represents the equation of meshing between the generated tooth surface and the rack cutter, it can be written as follows:…”

“…The back profile of the tooth not being used in operation could be designed to decrease the maximum tensile stress at the root of the tooth. This gear type can reduce the size and the weight of the gear and increase its load capacity [12,13].…”

Effect of Face Contact Ratio on Load Sharing Based Fillet Stress in Asymmetric Helical Gear Drives

“…D.V. Muni et al (2007) have studied the optimization of asymmetric spur gear drives for maximum bending strength using direct gear design method. Costopoulos and V.Spitas (2009) have proposed the asymmetric half -involute spur gear teeth geometry and also investigated the bending stresses at the root fillet.…”
