When such machinery is in operation, often at very high speeds of thousands of revs per minute, any imbalance will set up vibration and often noise. In addition, such imbalance will cause extra wear and loss of efficiency in the machine. The answer is to balance the affected parts of the machine so that it operates smoothly and efficiently. This book is a practical account of such balancing techniques e.g how to balance a rotor, how to set up and verify performance of a balancing machine, and procedures for on-site balancing. In addition, other common causes of vibration will be covered e.g. misalignment, bad bearings and looseness. This book is the distillation of a successful course run by the author and developed over 20 years. University engineering departments do not teach balancing techniques beyond the very basic, and there is a need for educators and engineers to have a practical book available on the topic. A practical book which will help the reader understand the importance of balance in today's high technology world Outlines the history of dynamic balancing and other vibration reduction techniques Profusely illustrated throughout 533 $aElectronic reproduction.$bAmsterdam :$cElsevier Science & Technology,$d2007.$nMode of access: World Wide Web.$nSystem requirements: Web browser.$nTitle from title screen (viewed on Aug. 2, 2007).$nAccess may be restricted to users at subscribing institutions 650 0$aBalancing of machinery 650 0$aMachinery$xVibration 655 7$aElectronic books.$2local 776 1 $cOriginal$z1856174654$z9781856174657$w(OCoLC)63134326 856 40$3Referex$uhttp://www.sciencedirect.com/science/book/9781856174657$zAn electronic book accessible through the World Wide Web; click for information 907 $a.b13654159$b03-03-22$c24-01-08 912 $a991003242359707536 996 $aPractical balancing of rotating machinery$91212777 997 $aUNISALENTO 998 $ale026$b24-01-08$cm$d@ $e-$feng$genk$h0$i0
