Análise comparativa entre dois métodos para alinhamento de máquinas rotativas

Abstract

The present work compare two methods of alignment of rotating machinery. The alignment by dial indicator and the laser alignment user to reduce vibration in equipment. Two dial indicators are used for measuring the relative positions between the shafts the moveable machine and stationary machine. The chosen methods for Face and Rim fixed the mechanism on the shaft of the stationary machine and through stem positioning two dial indicators with spindle gauging the shaft of the coupled moveable machine. One on rim and another on face. The data collection is from the rotation set where the dial indicators measure the change in the relative position between the shafts. That way we can perform an analysis indicating misalignment of the set and the necessary adjustments to the alignment. The laser equipment performs a most improver process involving several concepts replacing mechanical components for electrical, reducing the measurement errors and calculations the necessary adjustments to alignment. Coupling and its basic types are evaluated at work. The work presents a procedure to effect the alignment on alignment and balancing bench the laboratory dynamic systems and mechanical projects by methods evaluated.
