Directed lubrication tilting pad journal bearings are used for high peripheral speed conditions. In the bearing, oil is supplied between pads and it mixes outlet oil from an upstream pad at oil inlet region. But in some cases, especially high speed o

A direct-lubrication tilting pad bearing with a diameter of 120mm is tested to clarify the effect of the oil flow rate on the characteristics of the bearing. Measured characteristics are the bearing temperature and dynamic characteristics, namely, be

In this study, we intended to predict bearing temperature of oil bath tilting bearings with high degrees of accuracy, and developed a more detailed formula estimating mixing temperature at the inlet of the oil film on the pad. In order to consider th

In swash plate type piston pumps and motors, the slippers are used under heavy load. So the slippers are designed as a hydrostatic bearing to ensure reliability. However slippers behavior during operation is very complex, we must take into considerat

In the manufacturing process of single-shaft multistage centrifugal compressors for process gases, factory tests are conducted to confirm that the lateral vibration satisfies the allowable limits. One of the problems that must be taken care of during

Direct lubrication tilting pad journal bearings (TPJBs) require less oil flow, reduce power consumption, and offer cooler pad temperatures for operation at high surface speeds. Although apparently free of hydrodynamic instability, the literature show
