Available in PDF, EPUB and Kindle. Book excerpt: "The experimental methods have been thought necessary to prove the analytical and numerical analysis results or to establish various constants to enable the use of various theoretical formulas related to rolling bearing. There are various test rigs in literatures, these test rigs need to be classified and compared with each other to provide a guide for further bearing test rig optimum design. Rolling bearing test rigs found in literatures were classified here as full-scale bearing test rigs, element test rigs and the other test rigs according to the test requirements, test sample geometrical shape and test conditions. A full-scale bearing test rid can be used if the total rolling bearing assemble is tested to obtain sufficiently accurate test result. The element test rig can be used if only a bearing component of bearing raw material need to be tested to save time and cost. The test rigs found in literatures that designed for special purpose were classified as the other test rigs. Most of test rigs found in literatures are element test rigs categorized further into pure rolling contact and rolling-sliding contact according to operating conditions (speed, load, test sample surface roughness, size of abrasive particles in lubricating oil and lubrication film thickness). These two kinds of element test rigs were classified further according to the test sample geometrical shape. The test results got by an element test should be extrapolated into a real bearing application by analytical method. For the element test, different test rig configuration may lead to very different test result, but it is hard to say which test rig configuration is more important or reasonable without comparisons with the full-scale test. The main rolling bearing failure mechanism found in literature include: rolling contact fatigue failure, wear damage, crack damage, corrosion damage, lubricant deficiency, cavitation damage, vibration damage, electrical corrugation damage, fracture damage, mechanical damage, geometrical imperfection, dimensional instability. The majority of these failures often relate to bearing abuse, poor design, and lubrication failure. When all of the causes of premature bearing failure were eliminated, all normally loaded rolling bearings would still fail due to bearing material fatigue. Bearing material selection and material processing methods is also very important on rolling bearing performance. In practice, the identification of the primary cause of damage is not always easy because it is often obscured by consequential damage"--P. iii-iv.

Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: For the last four decades, Tedric Harris' Rolling Bearing Analysis has been the "bible" for engineers involved in rolling bearing technology. Why do so many students and practicing engineers rely on this book? The answer is simple: because of its complete coverage from low- to high-speed applications and full derivations of the underlying mathematics from a leader in the field. Updated, revamped, and reorganized for the new millennium, the fifth incarnation of this classic reference is the most modern, flexible, and interactive tool in the field. What makes this edition so revolutionary? For starters, the coverage is split conveniently into two books: Essential Concepts of Bearing Technology introduces the fundamentals involved in the use, design, and performance of rolling bearings for more common applications; Advanced Concepts of Bearing Technology delves into more advanced topics involving more dynamic loading, more extreme conditions, and higher-speed applications. Furthermore, each book in this edition includes a CD-ROM that contains numerical examples as well as tables of dimensional, mounting, and life-rating data obtained from ABMA/ANSI standards. Whether you are interested in the mathematics behind the empirical values or methods for estimating the effects of complex stresses on fatigue endurance, Rolling Bearing Analysis, Fifth Edition compiles the techniques and the data that you need in a single, authoritative resource.

Download or read book Experimental Analysis of Fault Diagnosis of Self Aligning Ball Bearing Under Various Speeds and Angular Misalignments Using Vibration Signal Processing written by Independently Published and published by . This book was released on 2018-09-17 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic equipments, in their vast majority, have rolling bearings in their components. Measurement and analysis of the values of rolling bearings vibration, on time, represent a safe and effective measure for identifying the state of wear of bearings, and to predict the evolution of their technical condition and of the entire equipment. The fault diagnosis of self aligning ball bearing (1205K type) at angular misalignments is the main concern of the study. This paper presents the detection of causes which lead to the damage of rolling bearing by using bearing condition signature spectrums in frequency domain and root mean square values of acceleration in time domain, by measuring its housing vibrations mounted in a test rig. The bearing fault simulator system is created for vibration signal observation by inducing fault in the bearing and misalignments in shaft. The main components of vibration observing system used is piezoelectric transducer, data transfer cable, vibscanner gadget and pc, signal investigation omnitrend software. A test bench consists of a motor and a shaft attached along with two different bearing housings with rotor disc at the centre giving constant loading. The particular imperfections are considered as defect in outer race, inner race and ball element and vibrations are recorded for five speeds and five different angles. It is clear from both the time domain and frequency domain signals that for the same defect size the maximum vibrations are produced by the bearing with ball defect and then by the outer race fault and lastly minimum by the inner race faulty bearing. So, on the basis of the results it becomes easy to recognize and diagnose the type of fault occurred in the bearing during it operation before the major failure.
