“…However, due to the restriction of many factors (sealing of film space, formation mechanism of film, and various bearing structures), the multi-points monitoring must be conducted, and the measurement for film pressure of bearings is hard to be achieved [11]. At present, there are two on-line monitoring methods, one method is that the pressure sensors are installed in the measuring holes punched on the shaft, and the data of film pressure is transmitted using the brush or mercury collection rings [12]. But the contact of ring produces more noises, which greatly affect the pressure, and furthermore, the reliability and the high cost of ring make its application limited.…”

Abstract.For acquiring the precise parameters of bearing in rotating machinery, and further to study the bearing characteristics, and considering the difficult and bottleneck problems with wired monitoring method for bearing, the on-line monitoring method of bearing based on wireless sensor networks (WSNs) is proposed in this paper. Two typical engineering applications, namely the bearing of freight train and the water-lubricated bearing are studied. The key issues in application of WSNs, including the energy consumption, the routing protocol, the design of node, the compressive and coding algorithm of vibration data, and the Doppler effect are solved. Finally, the simulation and experiment results show the effective of the wireless method proposed.

“…Pai et al [2] studied the non-linear analysis of water-lubricated journal bearings having multiple axial grooves under unidirectional constant load, unidirectional periodic load, and variable rotating load. Cabrera et al [3] and Geng et al [4] measured the lubricant film pressure of water-lubricated rubber journal bearings. Dai et al [5] presented a new water lubrication hybrid journal bearing that had round recess and cooling orifice restrictors for limiting temperature rise on the surface of bush directly and had stepped recesses for enhancing dynamic effect.…”

Abstract-Hybrid sleeve bearings are normally lubricated with high viscosity lubricant, the temperature of oil film increases with the increase of rotating speed. The low viscosity lubricant can decrease the temperature, which is the efficient method to increase the rotating speed of hybrid sleeve bearings. A current situation of the published research works on high speed sleeve bearing with low viscosity lubrication was summarized. The structure of high speed sleeve bearing with low viscosity lubrication was introduced, the effect of wall slip, cavitation, surface roughness, temperature and et al. on bearing properties was analyzed, and the significance of lubrication study for high speed journal bearing with low viscosity lubricant was discussed.

The increasing ecological awareness and stringent requirements for environmental protection have led to the development of water lubricated bearings in many applications where oil was used as the lubricant. The chapter details the theoretical analysis to determine both the static and dynamic characteristics, including the stability (using both the linearised perturbation method and the nonlinear transient analysis) of multiple axial groove water lubricated bearings. Experimental measurements and computational fluid dynamics (CFD) simulations by the Tribology research group at Queensland University of Technology, Australia and Manipal Institute of Technology, India, have highlighted a significant gap in the understanding of the flow phenomena and pressure conditions within the lubricating fluid.An attempt has been made to present a CFD approach to model fluid flow in the bearing with three equi-spaced axial grooves and supplied with water from one end of the bearing. Details of the experimental method used to measure the film pressure in the bearing are outlined. The lubricant is subjected to a velocity induced flow (as the shaft rotates) and a pressure-induced flow (as the water is forced from one end of the bearing to the other). Results are presented for the circumferential and axial pressure distribution in the bearing clearance for different loads, speeds and supply pressures. The axial pressure profile along the axial groove located in the loaded part of the bearing is measured. The theoretical analysis shows that smaller the groove angle better will be the load-carrying
