NBR15623-1 de 09/2008

Esta Parte da NBR15623 estabelece os procedimentos para a medição da excentricidade da ponta de eixo e para máquinas fixadas por flange, da concentricidade do diâmetro do encaixe do flange e da perpendicularidade da superfície de apoio do flange com relação ao eixo. This Part of the NBR15623 establishes the procedures for measurement of eccentricity for shaft end and for machines flange mounted, of concentricity for flange fitting diameter and the perpendicularity for flange support structure regarding to the shaft. This Part of ABNT NBR 15623 also establishes the basic dimensions for motors and shafts and the rating power for electrical rotating machinery covered by rhis regulation, as well as permissible maximum torque for AC motors for continuous operation. This Part of ABNT NBR 15623 applies to electrical rotating machinery for industrial use with the following dimensions: a) foot mounted which the height of shaft end is equal or higher than 56 mm and equal or lower than 400 mm; b) flange mounted type F wich circumference diameter that pass through the center of fitting holes is equal or higher than 55 mm and equal or lower than 1 080 mm; c) flange mounted type C wich fitting diameter is equal or lower than 406,4 mm.
