Download or read book Why Industrial Bearings Fail written by Kirshna Murty and published by Industrial Press. This book was released on 2022-08-31 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: A bearing is a common machine element used to constrain motion and reduce friction between moving parts. Bearings are used extensively in global industries, including automotive, construction, power generation, mechanical, chemical, mining, infrastructure, medical, food, etc. The estimated bearing market was valued at $128 billion in 2021, and expected to increase to nearly $227 billion by 2028. Unfortunately, sometimes bearings fail, and often at the most inopportune time. This is a source of great concern and expense to users, causing downtime and the loss of millions in damages, outages, and lack of productivity. While modern precision manufacturing and maintenance practices have reduced some of the premature failure, they haven't addressed many of the core problems that lead to bearing failure. This work presents a collection of different case studies in a multitude of industries where bearings have failed, and includes a failure description, observations, possible reasons for the failure, plausible cause and effect, and then discusses what might have been done to mitigate the problem and, when possible, provides solutions to prevent further failures. The author uses root cause failure analysis and explores such topics as alignment, lubrication, manufacturing defects, mounting practices, contamination, and fatigue. He then explains how one or a combination of these issues worked together to cause the failure, and offers preventive solutions to avoid future problems. Features Throughout the book, a classical RCFA approach is used for each case study, using a nine-step analysis with solutions: Define the problem Get information and input from various sources Locate the evidence Look for the mistakes Ishikawa / Fishbone Diagram Getting to the roots Solutions Create plans to implement the solution Monitor the solution and confirm if it works

Download or read book Root Cause Failure Analysis written by Trinath Sahoo and published by John Wiley & Sons. This book was released on 2021-05-06 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Root Cause Failure Analysis Provides the knowledge and failure analysis skills necessary for preventing and investigating process equipment failures Process equipment and piping systems are essential for plant availability and performance. Regularly exposed to hazardous service conditions and damage mechanisms, these critical plant assets can result in major failures if not effectively monitored and assessed—potentially causing serious injuries and significant business losses. When used proactively, Root Cause Failure Analysis (RCFA) helps reliability engineers inspect the process equipment and piping system before any abnormal conditions occur. RCFA is equally important after a failure happens: it determines the impact of a failure, helps control the resultant damage, and identifies the steps for preventing future problems. Root Cause Failure Analysis: A Guide to Improve Plant Reliability offers readers clear understanding of degradation mechanisms of process equipment and the concepts needed to perform industrial RCFA investigations. This comprehensive resource describes the methodology of RCFA and provides multiple techniques and industry practices for identifying, predicting, and evaluating equipment failures. Divided into two parts, the text first introduces Root Cause Analysis, explains the failure analysis process, and discusses the management of both human and latent error. The second part focuses on failure analysis of various components such as bolted joints, mechanical seals, steam traps, gearboxes, bearings, couplings, pumps, and compressors. This authoritative volume: Illustrates how failures are associated with part integrity, a complete system, or the execution of an engineering process Describes how proper design, operation, and maintenance of the equipment help to enhance their reliability Covers analysis techniques and industry practices including 5-Why RCFA, fault tree analysis, Pareto charts, and Ishikawa diagrams Features a detailed case study of process plant machinery and a chapter on proactive measures for avoiding failures Bridging the gap between engineering education and practical application, Root Cause Failure Analysis: A Guide to Improve Plant Reliability is an important reference and guide for industrial professionals, including process plant engineers, planning managers, operation and maintenance engineers, process designers, chemical engineers, and instrument engineers. It is also a valuable text for researchers, instructors, and students in relevant areas of engineering and science.

Available in PDF, EPUB and Kindle. Book excerpt: The era of lean production and excellence in manufacturing, advancing with sustainable development, demands the rational utilization of raw materials and energy resources, adopting cleaner and environmentally-friendly industrial processes. In view of the new industrial revolution, through digital transformation, the exploitation of smart and sophisticated materials systems, the need of minimizing scrap and increasing efficiency, reliability and lifetime and, on the other hand, the pursuit of fuel economy and limitation of carbon footprint, are necessary conditions for the imminent growth in a highly competitive economy. Failure analysis is an interdisciplinary scientific topic, reflecting the opinions and interpretations coming from a systematic evidence-gathering procedure, embracing various important sectors, imparting knowledge, and substantiating improvement practices. The deep understanding of material/component role (e.g., rotating shaft, extrusion die, gas pipeline) and properties will be of central importance for fitness for purpose in certain industrial processes and applications. Finally, it is hoped and strongly believed that the accumulation of additional knowledge in the field of failure mechanisms and the adoption of the principles, philosophy, and deep understanding of failure analysis process approach will strongly promote the learning concept, as a continuously evolving process leading to personal and social progress and prosperity.

Download or read book White Etching Crack Failure Mode in Roller Bearings written by Johan Luyckx and published by . This book was released on 2012 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some roller bearing applications are prone to the white etching crack (WEC) failure mode. The applications seem to have in common that they work under dynamic operating conditions. The specific feature of this failure mode is that the subsurface microstructure of a failed bearing contains modified material structures near cracks which are white after a nital etching test. In case of a WEC failure, the real lifetime of the bearing is much lower than the theoretical lifetime calculation. The hypotheses of fatigue overload, hydrogen, and accumulated plastic microstrain are evaluated and a root cause hypothesis is developed based on observations. The white etching material structures are interpreted as adiabatic shear bands generated by an impact load mechanism. We developed the root cause hypothesis that the dynamic operation of a roller bearing is generating a bearing internal pressure peak causing loads at high strain rate which result in material damage and initiate the WEC failure mode. Impact tests reveal a high sensitivity of through hardened martensitic and bainitic bearing steels for the adiabatic shear band failure mode. The origin of the bearing internal pressure peak is further explained based on available ElastoHydrodynamic Lubrication (EHL) experimental and simulation results. The generation of butterflies and WEC networks is interpreted as recrystallisation driven by high stress after many load cycles or a moderate stress combined with a high strain rate loading. The industrial experience is analysed from the perspective of the root cause hypothesis. The Weibull curve of a WEC bearing failure case is explained based on the material parameter full width at half-maximum (FWHM) at the raceway surface. The potential solutions of an optimised microstructure, black oxidized treatment, and hot assembly are identified based on positive industrial experience.
