Mechanische Schwingungen - Auswuchten von Rotoren - Teil 21: Beschreibung und Bewertung von Auswuchtmaschinen (ISO 21940-21:2022)
Overview
This document sets out the requirements for evaluating hard and soft bearing balancing machines that support and rotate: a) rotors with rigid behaviour at balancing speed (as described in ISO21940-11); b) rotors with shaft elastic behaviour and balanced in accordance with low speed balancing procedures (as described in ISO21940-12). This document contains the English translation of the International Standard ISO 21940 21:2022, which has been prepared by Technical Committee ISO/TC 108 "Mechanical vibration, shock and condition monitoring" (secretariat: BSI, Great Britain), Subcommittee SC 2 "Measurement and evaluation of mechanical vibration and shock as applied to machines, vehicles and structures", the secretariat of which is held by DIN (Germany).
