Abstract

Bu çalışmada AISI 8620 ve AISI 5115 çeliklerinden yapılan, modülü 1.5 ve 2 olan helisel dişli çarklara uygulanan gaz sementasyon ve düşük basınçlı sementasyon yüzey sertleştirme ısıl işlemlerinin dişli çarkların yorulma ömrü üzerindeki etkisi incelenmiştir. Yorulma analizi Solidworks Premium 2015 SP 2.0 CAD programı kullanılarak yapılmıştır. Helisel dişli çarkların ömür değerleri, yüzey sertleştirme işlemleri sonrasında oluşan sertlik dağılımına bağlı olarak belirlenmiştir. Düşük basınçlı sementasyon işleminin gaz sementasyon işlemine kıyasla, istenen yüzey sertlik ve efektif sert tabaka kalınlığını çok daha kısa işlem sürelerinde sağladığı belirlenmiştir. Dişlilerin ömür değerleri ve hasar yüzdeleri, malzemenin kimyasal içeriği, efektif sert tabaka kalınlığı ve yüzey sertlik değerlerinden etkilenmiştir.

Fatigue Analysis of Gas and Low-Pressure Carburized Helical Gears

Year 2020, Volume: 20 Issue: 6, 1124 - 1137, 31.12.2020

Abstract

In this study, the effect of case hardening treatments such as gas carburizing and low-pressure carburizing on the fatigue life was investigated for helical toothed gears made of AISI 8620 and AISI 5115 steels with modules 1.5 and 2. Solidworks Premium 2015 SP 2.0 CAD program was used for the fatigue analysis of the gear wheels. The total life values of the helical gears were determined depending on the hardness distribution that occurs as the result of case hardening treatments. Compared to the gas carburizing, it was found that the low-pressure carburizing process provided the desired surface hardness and effective case depth values within shorter processing times. The total life values and damage percentages of gears were influenced by the chemical content of the material, effective case layer thickness, and surface hardness values. For 36 Nm torque and 1400 rpm operating values in AISI 5115 helical gear wheels, fatigue life cycle was determined as 366,240,718 turns in non-heat-treated gear, 790,471,887 turns in low-pressure carburizing, and 720,619,942 turns in gas carburizing. These values were determined as 167,327,793 and 614,293,058, and 629,203,913 turns for 132 Nm torque and 212 rpm operating values in AISI 8620 helical gears wheels, respectively.
