| ABSTRACT The use of profile shift in involute tooth gearing has permitted the gear designer to utilize conveniently different parts of the involute tooth curve generated by the base circle. The procedure is called profile shifting or profile correction, which helps achieve desirable tooth-action and to avoid interference or undercutting and also the most dangerous tooth contact in the vicinity of the base circle. Altering a tooth-sum of a gear pair operating between a specified centre distance changes the operating pressure angle and hence necessitates profile shift. This profile shift can be distributed between the gears of the pair suitably. Such gear pairs display considerable lowering of contact stresses which is a more desirable characteristic for power transmission gearing. Few cases of altered tooth-sum gearing have been subjected to experimental tests, the performance of this gearing is compared vis-à-vis standard tooth-sum gearing. The results have been highly encouraging. Such findings suggest the use of altered toothsum gearing for power transmission applications. This paper presents the use of high profile shift gearing in improving the surface durability of gears. | ||
