Water Lubricated Journal Bearings: Marine Applications, Design, and Operational Problems and Solutions provides cutting-edge design solutions, common problems and methods for avoiding them, and material selection considerations for use of water lubricated journal bearings in marine environments. These bearings have many advantages, among them the absence of the potential for oil contamination. They are also sensitive, and their production processes can be challenging, but this book outlines techniques and concepts designed to overcome these challenges, emphasizing their role in durable and reliable propulsion systems in modern, safe, and environment-friendly shipping. Propeller shafts, water lubricated stern tube bearings, problems frequently encountered with water lubricated propeller shaft bearings and sliding bearings alongside solutions to these problems are all covered, as are the hydrodynamic properties of water lubricated bearings, operation at low revolution speeds, high speed bearings, hybrid bearings, and more. Foundational concepts of tribology related to friction, lubrication, wear, and fluid/solid and solid/solid interactions in ship stern tube and water lubricated turbine machinery are also discussed. - Provides cutting-edge design solutions and material selection considerations for water-lubricated journal bearings - Outlines common problems and solutions for overcoming them when working with water-lubricated propeller shaft bearings, sliding bearings, and hybrid bearings - Presents theoretical and experimental research on bearings, including the influence of bush shape imperfections and misalignment

Hydrodynamic Lubrication is the culmination of over 20 years close, collaborative work by the five authors and discusses the practical use of the formalization of low pressure lubrication. The work concentrates on the developments to journal and thrust bearings and includes subjects such as: • the dynamic behaviour of plain and tilting-pads • the thermal aspects • the positive and negative effects of non-cyclindricity and shape defects resulting from manufacturing or operation • the effects of inertia • the appearance of Taylor's vortices and of turbulence and their repercussions. The book contains an abundance of test results objectively compared with theoretical conclusions and a chapter on "technical considerations" to ensure that draft mechanisms will work satisfactorily under the imposed conditions. Hydrodynamic Lubrication is an essential reference book for future and practising engineers who want to put hydrodynamic and hydrostatic journal bearings and thrust bearings into operation under conditions of total safety.

Hydrostatic lubrication is characterized by the complete separation of the conjugated surfaces of a kinematic pair, by means of a film of fluid, which is pressurized by an external piece of equipment. Its distinguishing features are lack of wear, low friction, high load capacity, a high degree of stiffness and the ability to damp vibrations.This book reviews the study of externally pressurized lubrication, both from the theoretical and the technical point of view, thereby serving the needs of both researchers as well as students and technical designers. In this connection, design suggestions for the most common types of hydrostatic bearings have been included, as well as a number of examples. A comprehensive bibliography is included with each chapter providing up to date references for more in depth coverage.
