摘要：
The paper reports a comparative study for the performance of a multirecess 2-lobe hybrid worn journal bearing system compensated with different flow control devices, such as capillary, constant flow valve, orifice and membrane restrictors. The Reynolds equation governing the flow of lubricant in the clearance space of a 2-lobe multirecess worn hybrid journal bearing system together with restrictor flow equation has been solved using Finite Element Method. The proposed results helps to the proper selection of the type of compensating device and the value of offset factor which provides an improved and accurate bearing performance.
