RISFilm Thickness and Friction Investigations in a Fluid Film Thrust Bearing Employing A New Conceived Micro-Texture on Pads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the performance behaviors (coefficient of friction, minimum film thickness, and pressure distributions) of a fluid film thrust bearing using a newly conceived micro-texture on pads. In the numerical ...
Performance of Lubricated Rolling/Sliding Concentrated Contacts With Surface Textures: A Review
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Benefits of surface textures for improving the performance behaviors of tribocontacts are being explored and established by the investigators across the globe. But the consolidated information of findings of such explorations ...
Comparisons of Tribological and Vibration Behaviors of Textured Point Contacts of Bearing Steel Lubricated With Oil and Grease Under Starved Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Friction, wear, and vibration behaviors of oiland greaselubricated laser textured point contacts formed between AISI 52100 steel surfaces have been experimentally investigated under the unidirectional sliding motion using ...

Influence of Hydrodynamic Journal Bearings With Multiple Slip Zones on Rotordynamic Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper mainly reports stability investigations of rotors supported on fluid film journal bearings possessing multilocational slip-no-slip zones at the bush–film interface. The coupled solution of governing equations ...
Performance Studies of Powder-Lubricated Journal Bearing Having Different Pocket Shapes at Cylindrical Bore Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It becomes impossible to use conventional fluid film journal bearings in the hot working environments (500–800 °C) due to rapid thermal degradation of lubricating oils. Under this situation, powder lubricants prove beneficial ...
