Yağ Çalışma Sıcaklığının Dişli Yüzey Hasarları Üzerine Etkisi

Abstract

Bu çalışmada test dişlilerinin malzemesi, devir sayısı, yağlama yağı ve uygulanan yük sabit tutulmuş olup yağ çalışma sıcaklıkları değiştirilerek yüzey yorulma hasarları incelenmiştir. Deneysel çalışmalarda dişli numunelerinin deney öncesi ve sonrası ağırlıkları tespit edilmiş, yüzey pürüzlülükleri ölçülmüş, dişli yüzeylerinde mikrograf incelemeleri yapılmıştır. Sonuç olarak sıcaklığın artması ile doğru orantılı olarak yüzey pürüzlülüğünün ve aşınmanın da arttığı tespit edilmiştir.

Keywords

Effect of the Operating Temperature of Oil on Gear Teeth Surface Damages

Abstract

This study investigates surface fatigue damages by keeping fixed the material of test gear teeth, rotation speed, lubricating oil, and the applied load, and changing the operating temperatures of oil. In experimental studies, pre- and post-test weights of gear teeth samples were established, surface roughnesses were measured, and micrograph examinations were carried out on teeth surface. As a result, surface roughness and wear were established to increase in proportion to the rise in temperature of oil.

Keywords

• Gear fatigue
• Oil temperature
• Oil viscosity
• Spur gear
