Bu çalışmada, pinyon takımla imal edilen helisel dişli çarkların bilgisayar simülasyonu ele alınmaktadır. Dişli teorisi esas alınarak evolvent profilli kesici takımların ve imal edilen dişlilerin matematik
modelleri verilmiştir. Profil kaydırma ve asimetrik profil gibi tashihler de göz önüne alınmıştır. Matematik modellerden hareketle bilgisayar programları geliştirilmiş, evolvent profilli helisel dişlilerin
bilgisayar grafikleri elde edilmiştir. 3-Boyutlu katı model ve sonlu eleman modelleri gösterilmiştir.
Bu simülasyonla imalattan önce takım dizayn parametrelerinin dişli geometrisi üzerindeki etkileri
incelenebilir.

COMPUTERIZED TOOTH PROFILE GENERATION OF INVOLUTE HELICAL GEARS MANUFACTURED BY SHAPER CUTTERS

Öz

This paper studies the computerized tooth profile generation of helical gears cut with pinion-type shaper cutters. Based on the theory of gearing the mathematical models of pinion-type shaper cutters and
generated gears with involute teeth are given. The corrections on geometry such as addendum modification (profile shift) and asymmetric tooth profile are also considered. Computer simulation programs
are developed to obtain graphs of generating tools and generated teeth surfaces. Also 3-D solid and
finite element models of helical gears are obtained. The effect of tool parameters on generated gear can
be investigated before manufacturing.
