EFFECT OF THE DIFFERENT GEAR BASE GEOMETRIES OF HELICAL GEARS ON THE WEIGHT OF GEAR AND STRESS ANALYSIS
Abstract
The aim of this study, is to decrease weight of helical gears used frequently in power and motion transmission in order to provide energy and material saving. For this purpose, gear surfaces, where the stresses at minimal level are acted under normal working conditions, were removed for seven different geometries. The specimens modeled in SolidWorks 2010 package program were exported ANSYS Workbench 12.0 finite elements package program then stress analysis was accomplished. Throughout the whole analysis, steel AISI 1045 as a gear material was chosen. At the end, results obtained from performed study were presented in comparisons each other and the most appropriate design that provides 27 percent material saving was specified as a model 7 mm in diameter and has 6 circular holes drilled.

Abstract
Bu çaly?manyn amacy, enerji ve malzeme tasarrufu sa?lamak amacyyla güç ve hareket iletiminde syklykla kullanylan helis di?li çarklaryn a?yrlyklaryny azaltmaktyr. Bu amaçla di?li çarklaryn normal çaly?ma ?artlary içerisinde gerilmeye en az maruz kalan yüzeyleri 7 farkly geometride delinerek bo?altylmy?tyr. Modeller SolidWorks 2010 programy kullanylarak modellenmi? ve daha sonra olu?turulan katy modeller ANSYS Workbench 12.0 sonlu elemanlar paket programyna aktarylarak gerilme analizleri gerçekle?tirilmi?tir. Tüm analizlerde di?li çark malzemesi olarak AISI 1045 çeli?i seçilmi?tir. Gerçekle?tirilen çaly?ma neticesinde elde edilen sonuçlar birbiriyle kar?yla?tyrmaly olarak verilmi? ve en uygun tasarymyn malzemeden % 27 kazanym sa?layan 7 mm çapynda 6 adet dairesel delik açylan model oldu?u tespit edilmi?tir.
