Rolling Bearing Tribology


Book Description

Rolling Bearing Tribology: Tribology and Failure Modes of Rolling Element Bearings discusses these machine elements that are used to accommodate motion on or about shafts in mechanical systems, with ball bearings, cylindrical roller bearings, spherical roller bearings, and tapered roller bearings reviewed. Each bearing type experiences different kinds of motion and forces with their respective raceway, retainers and guiding flanges. The material in this book identifies the tribology of the major bearing types and how that tribology depends upon materials, surfaces and lubrication. In addition, the book describes the best practices to mitigate common failure modes of rolling element bearings. - Discusses important tribological implications surrounding the performance and durability of rolling element bearings - Describes how the different types of roller bearings work - Explores the reasons behind the failure of roller bearings and presents information on how to mitigate those failures




Grease Lubrication in Rolling Bearings


Book Description

The definitive book on the science of grease lubrication for roller and needle bearings in industrial and vehicle engineering. Grease Lubrication in Rolling Bearings provides an overview of the existing knowledge on the various aspects of grease lubrication (including lubrication systems) and the state of the art models that exist today. The book reviews the physical and chemical aspects of grease lubrication, primarily directed towards lubrication of rolling bearings. The first part of the book covers grease composition, properties and rheology, including thermal and dynamics properties. Later chapters cover the dynamics of greased bearings, including grease life, bearing life, reliability and testing. The final chapter covers lubrications systems – the systems that deliver grease to the components requiring lubrication. Grease Lubrication in Rolling Bearings: Describes the underlying physical and chemical properties of grease. Discusses the effect of load, speed, temperature, bearing geometry, bearing materials and grease type on bearing wear. Covers both bearing and grease performance, including thermo-mechanical ageing and testing methodologies. It is intended for researchers and engineers in the petro-chemical and bearing industry, industries related to this (e.g. wind turbine industry, automotive industry) and for application engineers. It will also be of interest for teaching in post-graduate courses.

Bearings


Book Description

Bearings: A Tribology Handbook is a practical guide on bearings, based on materials published in the first edition of the Tribology Handbook. The handbook has been updated matching international requirements. The book is divided in four main parts. The first part is a description of different bearing types and forms pertaining to continuous and oscillatory movements. A selection of journal and thrust bearings as to their different load capacity, performance, and special environmental conditions is explained. The second part deals with the physical properties and load capacity of plain bearings. Other kinds of bearing, such as the dry rubbing bearings; porous metal bearings; grease, wick, and drip fed journal bearings; ring and disc fed journal bearings; steady load pressure fed journal bearings; high-speed bearings; and crankshaft bearings, are considered regarding their performance, maintenance, and suitability to specific conditions. The third part focuses on one type of bearing: the rolling bearing. The selection, composition, shaft and housing design, and fitting and mounting for this type is discussed. The last part explains special bearing types such as slide bearings, instrument jewels (which are a combination of a steel pivot and a synthetic sapphire jewel), and electromagnetic bearings that are essentially powerful electromagnets. The need for surface treatments and coatings is then explained for optimum usage. The handbook is useful for design engineers, mechanical engineers, and material researchers. Mechanical, aeronautical, and automotive students; car mechanics; and those interested in machine and car maintenance will find this handbook a handy reference.

Advanced Concepts of Bearing Technology


Book Description

Part of the fifth edition of the classic Rolling Bearing Analysis, this book examines bearing performance and service life for more complex loading, more extreme operating conditions, and higher-speed applications. Several topics are unique to this work, including mathematical relationships for internal load distribution under conditions of high speed, combined radial, axial, and moment loading, as well as the effects of various types of profiling. The authors also delve into the mathematical development of rolling element-raceway lubricant film thickness and contact friction, the stress-life method for calculating bearing fatigue, and the effects of shaft and supporting structure flexure on bearing loading and deflection.
