THEORETICAL TESTS OF HYDRODYNAMIC JOURNAL BEARING WITH SELF-ALIGNING SPHERICAL SUPPORT
Journal Title: Tribologia - Year 2009, Vol 226, Issue 4
Abstract
A new concept of a hydrodynamic bearing computer model with selfaligning spherical support is presented in the paper. It takes into account the interaction between the bearing and spherical support. The model is composed of two modules. The first module is used for calculating hydrodynamic pressure distribution, and the second one (FEM module) describes the tribological characteristics of the spherical support of the bearing. During the simulations, both bearing geometry and spherical support geometry were changed. Several bearings were tested, varying clearance, length and preload. Different spherical seats were also studied, varying clearance and friction coefficient. The influence of the groove in the bearing shell sliding surface on tribological behaviour was also investigated. The proposed computer model offers an efficient design stage simulation of the behaviour of a sliding bearing in a spherical support. The model is being verified during experimental tests in a modernised test rig.<br/><br/>
