How to Correct One of the Most Pervasive Machine Problems - Misalignment. The misalignment of shafts and other components 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 enigneer and author in the field, this easy-to-follow, step-by-step resource shows you how to: Diagnose Misalignment - using vibration instruments, noise, dial indicators, hand feel, and visual observations. Perform Precision Alignments - using dial indicators, lasers, optical, and electronic measuring instruments. Graphical plotting techniques are illustated with examples of the reverse-indicator method, face-and-rim, 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 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 tw-machine one-coupling horizontal systems, to long drive shafts, large and heavy machines, multiple machne trains, vertical shafts, single-bearing generators, and reciprocating machines. This authoritative guide also covers bearing alignments, gear alignment, and pulley alignements. It also includes specific chapters on couplings, optical tooling, and laser systems. Plus a valuable appendix contains generic alignment specifications and drawings to make an alignment fixture.
