Published Online: June 17, 2011
...Roberto Bassani This chapter deals with a hydrodynamic journal bearing provided with hollow bushings, capable of supporting very high loads, even at low speeds, at which separation between the shaft and the housing’s bushing is induced by a specific self-regulating hydrostatic system. The same...

...Jun Wen; M. M. Khonsari; D. Y. Hua A three-dimensional computational thermal contact model is developed. The approach utilizes a combination of the transfer matrix and finite element methods. The frictional heat generated at the contact interface is instantaneously partitioned between the bushing...

... bench and some preliminary experimental results. A rotor of 1 kg mass and 37 mm diameter is rotated up to 75,000 rpm by an air turbine machined on the rotor. Capacitance probes, placed in two radial planes, allow orbit scanning of both the rotor and the bushing at different rotating speeds and suitable...

...Xiaobin Lu; M. M. Khonsari A series of experimental results is presented to explore the frictional characteristics of a grease-lubricated journal bearing. Load, grease type, and bushing material are varied to examine their effects on the friction coefficient. The results attest to the existence...

... function is developed in a form that is effective over short or long time scales and local to the source. This enables the transient thermal response of an auxiliary bearing to be assessed for a range of dynamic contact conditions. Auxiliary bearings consisting of fixed bushings and free to rotate inner...

... at the mid-plane of the bearing, temperature profiles at the oil-bush and oil-shaft interfaces, bush torque, oil flow rate, and the position of the shaft were measured for variable operating conditions. Shaft rotational speed ranged from 1000 to 4000 rpm and two different values of applied load were tested...

... for solids. It is known that the thermal transients on the film-solid interfaces and the dynamic loading have the same period (one cycle). However, beyond the thermal boundary layers, the time scale for thermal transient in the journal and bushing are several orders of magnitude greater than those...
