Journal bearing design
NettetJournal bearings, which are used in all kinds of rotating machinery, do not only support static loads, such as the weight of rotors and load caused by transmitted torque of reduction gears, but are, in addition almost the only machine element that is able to suppress various exciting forces acting on the rotating shaft. Nettet12. okt. 2009 · The success of modern journal bearings is due to the understanding that lubrication, the function of which is to separate the surfaces, is an integral part of journal bearing design. A journal bearing may be subject to four types of lubrication, namely: Hydrodynamic, hydrostatic, boundary and solid film. However, only hydrodynamic and …
