Our Bearings

Pages : 96

Book Description
Our Bearings is a collection of narrative poetry that examines and celebrates Anishinaabe life in modern Minneapolis. Crafted around the four elements—earth, air, water, and fire— the poems are a beautifully layered discourse between landscapes, stories, and the people who inhabit them. Throughout the collection, McGlennen weaves the natural elements of Minnesota with rich historical commentary and current images of urban Native life. Reverence for wildlife and foliage is pierced by the sharp man-made skylines of Minneapolis while McGlennen reckons with the heavy impact of industrial progress on the souls and everyday lives of individuals. While working with both traditional and contemporary form, McGlennen’s unique use of space and rhythm creates poetry that is both captivating and accessible. Our Bearings does not attempt to speak for a population; rather it offers vibrant stories and moments that give voice to pieces of a large and complex tapestry of experiences. Through keen observation and a deep understanding of Native life in Minneapolis, McGlennen has created a timely collection that contributes beautifully to the important conversation about contemporary urban Native life in North America and globally.

Grease Lubrication in Rolling Bearings

Pages : 472

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.

Air Bearings

Languages : en
Pages : 592

Book Description
Comprehensive treatise on gas bearing theory, design and application This book treats the fundamental aspects of gas bearings of different configurations (thrust, radial, circular, conical) and operating principles (externally pressurized, self-acting, hybrid, squeeze), guiding the reader throughout the design process from theoretical modelling, design parameters, numerical formulation, through experimental characterisation and practical design and fabrication. The book devotes a substantial part to the dynamic stability issues (pneumatic hammering, sub-synchronous whirling, active dynamic compensation and control), treating them comprehensively from theoretical and experimental points of view. Key features: Systematic and thorough treatment of the topic. Summarizes relevant previous knowledge with extensive references. Includes numerical modelling and solutions useful for practical application. Thorough treatment of the gas-film dynamics problem including active control. Discusses high-speed bearings and applications. Air Bearings: Theory, Design and Applications is a useful reference for academics, researchers, instructors, and design engineers. The contents will help readers to formulate a gas-bearing problem correctly, set up the basic equations, solve them establishing the static and dynamic characteristics, utilise these to examine the scope of the design space of a given problem, and evaluate practical issues, be they in design, construction or testing.

Bearings and Distances

Book Description
Bearings and Distances by Glenn Arbery, is a novel of comic ironies and tragic recurrences set in the "post-racial" moment of the American experiment. In the summer after Barack Obama's election, Hermia Watson, a scholar of black history, lures the famous (and famously irresponsible) Professor Braxton Forrest back to his hometown in Georgia, using his two daughters as unwitting hostages. Returning alone while his pious wife continues touring Italy, Forrest arrives to the tremblings of his abandoned past and a confrontation with the Furies he thought modernity had left behind. In the course of a few days, Hermia realizes what violent revelations she has begun to unleash about her former lover, her mother, and her own identity-but it is too late to stop what is coming to light. Arbery revisits the obsessions of the 20th century Southern renaissance in a work that satirizes misconceptions and shallow pieties but takes seriously the wisdom of the Southern literary tradition-and its classical antecedents.

Book Description
Bearings are used in the construction of bridges, for the distribution of loads between different elements and for compensating stresses. This volume describes their construction, function, calculation and applications, and is supplemented by normative regulations and research results. The book takes account of EN 1337 standards, which are binding on a European level. It also takes into account the latest experiences gained in practice as well as on the basis of recent tests, and includes examples for the correct placing of bearings and dampers.

Hydrodynamic Lubrication

ISBN: 0080534317
Category : Technology & Engineering
Languages : en
Pages : 499

Book Description
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.
