Abstract:
To obtain a new method to improve hydrodynamic bearing carrying capacity, hydrodynamic journal bearing’s characteristics as well as the current study direction are analyzed. According to the calculation of general cylindrical hydrodynamic journal bearing, the mathematic model for sinusoidal surface hydrodynamic bearing’s carrying capacity is established. It is used to calculate, analyze and compare these two bearings’ carrying capacity with example. The bearing, which has the characteristic of sinusoidal surface, has stronger carrying capacity than general cylindrical hydrodynamic bearing. Wha

Abstract:
Survey of patents on bearings indicates the maturity of hydrodynamic and rapid development of magnetic bearings. Active magnetic bearings are costlier compared with permanent magnetic bearings. To understand the performance characteristics of permanent magnetic bearings, an experimental setup has been developed. Experimental studies on radial permanent magnetic bearings demonstrated the drawbacks, such as high axial thrust and low load capacity. This has led the authors to hybridize the permanent magnet with hydrodynamic technology and to explore the possibility of achieving the low starting t

Abstract:
Nonequilibrium molecular dynamics simulation is used to simulate the hydrodynamics lubrication in the nanoscale bearing. A physical model of the nanascale bearing that the thin liquid water film confined between two solid walls has been set up. The simulation results indicate that the hydrodynamic pressure profiles as the macroscopic state are formed in nanoscale bearings. The hydrodynamic pressure increases with increasing shear velocity, and corresponding load capacity also increases with increasing sliding velocity of the upper driven wall. These results are in accordance with classical Rey

Abstract:
Fluid-structure interactions in hydrodynamic bearings result in load carrying and drag forces which give the bearing its characteristics. While these bearings offer many benefits as machine components, one of their shortcomings is their limited efficient range. In this paper, we demonstrate the use of micron-scale actuators to actively control the thrust and drag forces on a slider bearing. We show that for a set of control parameters, we are able to affect the performance of a bearing by more than 100 percent during operation, increasing the bearing’s range of operation.

Modern power engine concepts and environmental restrictions demand oil-free lubrication of rotors, for example, by gas bearings.

The predicted values of the Sommerfeld number are comparable to theoretical results from engineering tribology literature.

Abstract:
Oil-film hydrodynamic bearings are one of the most common forms of bearing used in rotating machinery. Because of their effect on system unbalance response and stability, care has to be exercised in the design of machines running in hydrodynamic bearings—for example they cannot usually be used in machines operating at high rotational speeds when the steady load on the bearing is low. A novel form of hydrodynamic bearing which incorporates recesses in the bearing surface has been proposed by the authors which improves the dynamic characteristics; however, earlier work has not fully assessed the

The Morton effect (ME) results from the synchronous, thermal excitation of a rotating shaft because of the uneven viscous shearing in hydrodynamic bearings and the asymmetric temperature distribution in shafts. The temperature difference bends the rotor, reducing the film thickness and increasing the thermal unbalance, which may cause excessive vibration level and unsteady phase angle. To predict the potential thermal instability from the ME, the finite element method is used to solve the transient rotordynamics and temperature distribution in the lubricant, bearing and shaft.

Abstract:
Abstract Hydrodynamic bearings have to fulfill different requirements, depending on the operating conditions. Yet, conventional hydrodynamic bearings could not be used in critical operating conditions such as permanent start / stop operations. This is the reason why rolling bearings are currently used for frequent starting operations and low circumferential velocities, as they occur in wind turbines. In order to operate hydrodynamic bearings in a fail-safe manner even under these increased requirements, new bearing materials are needed. Within this study two new bearing material concepts are d
