Analysis of journal bearing regarding number and position of lobes
M. N. V. M. Mallikarjuna Rao and Y. Venu Babu
This project entirely done by considering the basic design of a journal bearing from BHEL, Hyderabad. Major considerations in journal bearing are regarding stresses developed and vibrations produced. By utilizing the basic design, designs for no-lobe, one-lobe, two-lobe, three-lobe, four-lobe, and six-lobe has been generated in order to make a static and dynamic analysis on the journal bearing regarding no. of lobes. A lobe is a portion obtained by removing a circular portion of a known radius on the internal surface of the bearing, which results in good lubrication of the bearing, due to increase flow of lubrication. As the removal portion was in microns thickness, which may not show effect on the structural strength of bearing, by performing static analysis on types of bearings we determine the stresses developed in the structure based on the no. of lobes, position of lobe. No. of lobes, position of lobe can also be considered as criteria for selecting a journal bearing. More number of lobes may increase the lubrication but it may also decrease its strength so we concentrate on this issue also. These lobes may also result in generation of vibrations, which will be concluded by dynamic analysis.rnSoftware used are CREO 1.0 for modeling and ANSYS 15.0 for analysis work.
