TLDR
In this article, the effect of oil groove location and supply pressure on the oil feed rate of a journal bearing was investigated and the results indicated that oil groove position has a great influence on oil feed ratio.Abstract:
Oil feed rate is an important parameter governing the operating characteristics of a journal bearing. In the present paper investigation is carried out to explore the effect of oil groove location and supply pressure on the oil feed rate to the bearing. These results are further used to get variation in Sommerfeld number and attitude angle for different oil groove locations and supply pressures. The results indicate that oil groove location has a great influence on oil feed rate to the bearing. It is also observed that oil supply arrangement does not have a significant influence on Sommerfeld number and attitude angle.read more
