Profil Kaydırmalı Silindirik Evolvent Dişli Çarkların Matematik Modellenmesi

Öz

Bu çalışmada kremayer takımla imal edilen evolvent profilli dişli çark mekanizmalarının modellenmesi ele alınmıştır. Dişli teorisi ve imalat metodundan hareketle profil kaydırmalı pinyon ve çarkın tam matematik modeli verilmiştir. Asimetrik diş profile de göz önüne alınmıştır. Bir bilgisayar programı geliştirilerek profil kaydırmanın imal edilen dişli geometrisindeki etkileri incelenmiştir. Sayısal uygulamalar matematik modelin ve programlamanın doğrulunuğu ve geçerliliğini göstermiştir.

Mathematical Modelling of Profile-Shifted Cylindrical Involute Gears

Öz

This paper studies the equations of involute gears manufactured by rack-type cutters. Based on the gear theory and production method a complete mathematical model of a profile-shifted gear pair is given. Also asymmetric tooth profile is considered. A computer simulation program is developed to investigate the effect of profile shifting on the generated teeth surfaces. Numerical examples demonstrate the verification and validation of the simulation model.
