A BEARING APPLICATION USING MAGNETORHEOLOGICAL FLUIDS
Electrorheological Fluids and Magnetorheological Suspensions, 2002A conventional automotive driveline center bearing (CB) consists of a roller bearing that rests on a U-shaped support, which includes a bladder formed by an elastomer, providing damping for radial vibrations between the roller bearing and the housing.

Evaluation of Bearing Grinding Fluids
Key Engineering Materials, 2008Grinding tests and trials on production equipment is a most expensive proposition. The expense is not only with respect to the monetary cost, but also the down time associated with interrupting a production line to make special runs and set-ups. That high cost is generally the reason given why not to conduct production grinding tests.

Fluid-lubricated Thrust Bearings
1991So far in this book the contact of bodies in relative transverse or sliding motion has been considered for the important case of sensibly dry contact. In such situations, which are common in many everyday applications, there is by definition intimate contact between the sliding, or rubbing, pairs of surfaces, and the consequences of this physical fact ...

Fluid-lubricated Journal Bearings
1991In Chapter 5 bearings of plane form only were considered and these were shown to be of use in supporting loads which act at right angles to their plane. Bearings of this type are generally recognised as thrust bearings. However, another important type of bearing is the journal bearing. Journal bearings are used to support rotating circular shafts which

The Fluid Pivot Journal Bearing
Journal of Lubrication Technology, 1977A promising new type of tilting pad journal bearing—the Fluid Pivot journal bearing—is described. The long development history of this bearing is summarized, showing how the design evolved through research and testing. Static and dynamic performance features of the bearing are presented, with sample test results compared with predictions based on an ...

Fluid film bearings are commonly used in heavy rotating machines because they possess not only high load carrying capacity but also inherent damping properties. Unlike rolling element bearings, fluid film bearings are an important machine element which offers, in addition to support stiffness, substantial damping to insure rotordynamic stability.

Porous Rayleigh Step Bearing with Second‐Order Fluid
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1990AbstractThe theoretical analysis of a porous Rayleigh Step bearing lubricated by a second‐order fluid is considered. An approximate method for the solution of the governing fluid film equations and Darcy's equations for a porous region is proposed.

Laser microfabrication of bearing structures for fluid bearing motor system
CLEO/Pacific Rim 2003. The 5th Pacific Rim Conference on Lasers and Electro-Optics (IEEE Cat. No.03TH8671), 2004A 355nm DPSS laser with an output power of up to 1W is used to prevent heat creation during the fabrication. The laser is directed by a series of mirror and lens to focus down to the bearing surface. A 4-axis motion control system is used to move the sample, so that the laser will scan along the defined path to create journal/thrust-bearing structures ...
