There are many types of bearings available, each used for different purposes and different conditions. Two major types of bearings are contact bearings and noncontact bearings. By considering the ball material, I separate the contact bearings to steel bearings and ceramic ball bearings. On the other hand, there are bearings that can run without any contact between the sliding surfaces in the be...

An elastically deformable bearing ring is investigated. The piezo-actuated shaping of the elastic as well journal motion are coupled and determine height lubrication gap which takes a crucial part in theory hydrodynamic lubrication. influence active-dynamic on rotor dynamic behaviour has been investigated [1], especially for two-lobe bearing. present investigations aiming at active-static ring,...

Cavitation has a potential effect on the performance of full circle journal bearings. This paper studied effects cavitation steadily loaded bearings, with purpose analyzing necessity adopting mass-conserving model for ordinary The Christopherson’s method and Elrod algorithm were implemented to represent non-mass-conserving Reynolds Jakobsson-Floberg-Olsson (JFO) theory, respectively. difference...
