摘要:

This paper is concerned with squeeze film damping in hydrostatic pads having the various types of compensation normally used (i.e., capillary, orifice and constant-flow). A computerized analysis is used to determine bearing squeeze film pad performance with the various compensation types.

摘要:

The various factors that determine the stability and separation rate of oil from oily water mixtures are reviewed. The effect of droplet size, viscosity and unique interfacial properties promoted by the presence of surface-active agents are considered. The appropriate means to handle the separation/removal of oil from waste water effluents, as influenced by these factors, will be discussed. Wherever possible, first principles are applied; conversely, other areas are indicated where the nature of the problem dictates the reliance on empirical results and test data. Specific problems, properties and equipment are used throughout the presentation to illustrate the various concepts.Presented at the 24th ASLE Annual Meeting in Philadelphia, May 5–9, 1969.

摘要:

The precision components used in modern fluid powered machinery demand that strict consideration be given to cleanliness levels of the operating fluid. All fluid components exhibit an explicit sensitivity to the presence of contamination. When the contamination level of the fluid exceeds the tolerance level of the components, the performance, reliability and life of the system become affected. In order to establish a contamination control condition, the tolerance level of the components must be represented in a quantitative manner commensurate with the contamination level of the fluid.

摘要:

The inherent self aligning capability and superior resistance to thermal distortion, of the gas-lubricated tilting-pad thrust bearing, can often offset load capacity limitations and make it an attractive compromise for many applications. A numerical treatment for analyzing the tilting-pad thrust bearing is presented along with extensive performance information for a particular pad geometry. An optimum hydrodynamic crown profile and related dimensions are determined. A design procedure and sample problem are also presented.Presented at the 24th ASLE Annual Meeting in Philadelphia, May 5–9, 1969.

摘要:

The performance of centrally loaded liquid-lubricated 180° partial hydrodynamic journal bearings with shaft misalignment is considered. Misalignment is restricted to shaft tilt about an axis normal to a plane bisecting the bearing arc, as would arise from elastic deflection of the shaft under load. The results of numerical calculations for L/D ratios of 1, ½, and ¼ and a range of tilt angles are presented in the form of nomograms, design charts and tables. The effect of misalignment on bearing performance is discussed and illustrated with sample calculations.Presented at the 24th ASLE Annual Meeting in Philadelphia, May 5–9, 1969.
