Machinery vibration: Alignment
The misalignment of shafts and other component is one of the most common causes of vibration and failures. Here, at last is a practical handbook that enables you to eliminate this costly problem. Written by a pioneering and author in the field, this easy-to-follow, step-by-step resources shows you how to: Diagnose Misalignment - using vibration instruments, noise, dial indicators, hand free, and visual observations. Perform Precision Alignment - using dial indicators, lasers, optical, and electronic measuring instruments. Graphical plotting techniques are illustrated with examples of the reserve-indicator method, face-and run, and many variations. Move Machines - from small ones to the largest ones with orchestrated positioning techniques. Judge Acceptability - with alignment tolerances based on speed and stress and stresses at the joints. Deal with Complicating Factors - such as faulty foundations, bent shafts, soft foot, bar sag, piping strain, and thermal growth. Align Specific Machines - from normal two-machine one-coupling horizontal system, to long drive shafts. large and heavy machines, multiples machine trains, vertical shafts, single-bearing generators, and reciprocating machines. This authoritative guide also covers bearing alignments, gear alignment, and pulley alignment specifications and drawings to make an alignment fixture.
