Özetçe— Dönme i lemine sahip makinelerde, hayati öneme sahip olan rulmanlar n ar za durumlar n n izlenmesi ve daha önceden hatalar n tespit edilmesi, prosesin aksamamas aç s ndan büyük önem ta maktad r. Bu çal mada, rulman bile enlerinden olan iç bilezik üzerine lazer n ile belirli boyutlarda yapay hatalar olu turulmu ve rulman-mil düzene inde titre im sinyalleri elde edilmi tir. Çal mada rulmanlarda meydana gelen ar zalar n boyutunu uyarlanabilir sinirsel-bulan k mant k ç kar m sistemi modelini kullanarak te his etmek amaçlanm t r. Toplanan titre im verilerinin gerçek zamanda özellikleri ç kar ld ktan sonra belirli a rl klarla çarp lm ve olu turulan s n fland rma modeline giri olarak verilmi tir. Lazer ile olu turulan 0,15cm, 0,5cm, 0,9cm çaptaki iç bilezik hatal rulmanlar n ç kar lan özelliklerinin hatan n boyutuna ba l olarak farkl oldu u gözlemlenmi tir. Bu özellikler kullan larak ANFIS s n fland rma modeli geli tirilmi ve rulman n iç bilezi inde meydana gelen hatan n büyüklü ü, gerçek hata de erinden %2.40 bir farkla bulunmu tur. Daha sonra ANFIS ç k nda bulunan hata de erlerine uygulanan 0.1mm e ik de er ile hata band olu turulmu ve bütün tahmin de erlerinin bu hata band içerisinde ç kt görülmü tür.

In this study, certain sizes artificial faults are generated by the laser beam on inner rings of bearing and vibration signals are obtained from these bearings in a shaftbearing setup. It is aimed to diagnose the size of the defects occurring in the bearings by using adaptive neuro-fuzzy inference system (ANFIS) model in the study. After extracting the real-time features of obtained vibration data, they are multiplied by the specific weight and they are given as input to the generated classification model. It has been observed difference of features extracted from of 0.15 cm, 0.5 cm, 0.9 cm diameter inner ring faulty bearings created by the laser depending on size of faults. ANFIS classification model is developed by using these features and the size of the faults occurring in these bearings were calculated with an actual error 2.40 %. Then a error band are created with 0.1mm threshold value and it is observed that all the predicted values are inside this error band. Keywords— diagnostics, ANFIS, bearings faults, classification
