Abstract

Condition monitoring of ball bearings by analyzing vibration signals is successfully applied both numerically and experimentally. The most critic point in vibration analysis is early and successful detection of defect formation. The characteristic vibrations due to these defects ought to be understood well enough for this reason. In this study, localized defects in balls and rings of an angular contact ball bearing are modeled and deformations at the contact between ball and rings as well as internal forces are analyzed.

Özet

Makinalarda sıklıkla kullanılan rulmanlardaki hasarın, titreşimlerin ölçülmesi ve analiziyle tespit edilebileceği birçok sayısal ve deneysel çalışmayla gösterilmiştir. Titreşimlerin analiziyle kusur tespitindeki en kritik nokta, kusurun rulmanın çalışmasını engelleyecek seviyeye gelmeden önce ve doğru olarak tespit edilebilmesidir. Bunun için kusur sonucu ortaya çıkan titreşim davranışının iyi bilinmesi gereklidir. Bu çalışmada açısal temaslı bir bilyalı rulmanın dış bileziğinde, iç bileziğinde ve yuvarlanma elemanında oluşan yerel kusurlar modellenmiş, rulmanda oluşan ezilmeler ve iç kuvvetler analiz edilmiştir.
