Tribological Behaviors and Meshing Efficiency of a Novel Planar Ball Reducer Based on the Elastohydrodynamic Lubrication Theory
(The American Society of Mechanical Engineers (ASME), 1/9/2023 1)A novel planar ball reducer (NPBR) is invented in which the relative velocity of meshing surfaces is reduced to achieve high mechanical efficiency. In order to acquire an accurate quantitative analysis on the efficiency ... -
Numerical Study on Method for Reducing Film Pressure and Its Fluctuation due to Surface Roughness in Elastohydrodynamic Lubrication Contact
(The American Society of Mechanical Engineers (ASME), 11/23/2022)One of the methods to avoid rolling contact fatigue is to reduce the film pressure due to surface roughness and the magnitude of its fluctuation. The roughness on rolling/sliding concentrated contacting surfaces has generally ... -
