... tribological test (ASTM D2266) and simultaneously in a rolling bearing at various speeds and loads against two commercial greases as the benchmark. The vibrations and shock pulse measurements are recorded to assess the bearing performance. The tribo-dynamic investigation suggests that the eco-friendly nano...

...–thermal–load coupling model, a 30,205 tapered roller bearing with curved contact is examined by reading the real-time key point temperatures using thermocouple. Finally, the effectiveness of the presented model is verified through experiments and comparison. To simplify the analysis of the contact...

...Hiromu Hashimoto; Tadashi Namba Grooved thrust air bearings are widely used to support high-speed, low-loaded shafts in many rotating systems because of their low friction, noiseless operation, and simple structure. Several types of groove geometries, such as straight line, spiral, and herringbone...

...Hiromu Hashimoto; Masayuki Ochiai Hydrodynamic gas film bearings are widely used for very-high-speed, lightly loaded rotating machinery. In the design of hydrodynamic gas film bearings, it is of cardinal importance to enhance the stiffness of gas films to minimize vibration due to external...

...Jun Sun; Changlin Gui There is direct interaction between crankshaft and bearing in an internal combustion engine. The effect of lubrication status of bearing was not considered in the present calculation of crankshaft strength. A given oil film pressure distribution of bearing was generally used...

...Woon Yik Yong; Patrick S. Keogh Annular components are used widely in engineering systems and include bearing bushes and races, which may be exposed to extreme operating conditions. A method to establish the localized transient thermoelastic deformation of a homogeneous two-dimensional annular...

...Shigeka Yoshimoto; Makoto Yamamoto; Kazuyuki Toda This paper describes the pressure distribution in the bearing clearance of circular aerostatic thrust bearings with a single air supply inlet. For high air supply pressure, large bearing clearance, and a relatively small bearing outer radius...

...M. S. Kalsi, Ph.D.; P. D. Alvarez; D. Somogyi, Ph.D.; Aaron Richie A load-responsive hydrodynamic thrust bearing has been developed that has capabilities to operate under higher load and speed combinations than the current bearing designs used in roller cone drill bits, downhole drilling motors...
