Additionally, in an annex, guidelines are given on the information by which users provide their data and requirements to a balancing machine manufacturer. Mechanical vibration and shock - Range of idealized values to characterize seated-body biodynamic response under vertical vibration.
It covers both the machines that measure out-of-balance effects on soft bearings and those thatmeasure this on hard bearings. Tests for other machine capacities and performance parameters are notcontained in this International Standard. Basic Definitions and Transducers.
Description and evaluation of balancing machines. They have largely replaced soft- bearing machines.
This document may also be used as a general specification for purchasers in procuring suitable vertical single-plane balancing machines. It covers both the machines that measure out-of-balance effects on soft bearings and those that measure this on hard bearings.
Full Description This International Standard gives requirements for the evaluation of the performance and characteristics of machines for balancing rotating components. This document was developed for hard-bearing balancing machines but may also be used for existing soft-bearing balancing machines. This document has been replaced.
For periodic tests, simplified procedures are specified. This document may also be used as a general specification for purchasers in procuring suitable horizontal balancing machines.
Requirements for instruments for measuring vibration severity of rotating and reciprocating machines. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. General dimensions and capacities b.
Guidance as to the manner in which users should state their requirementsis given in annex B. Measurement of Structural Vibration. Standardization of balancing machine to rotor interfaces is intended to enable a set of tooling for a particular component to be used on a variety of machines in one capacity range. Mechanical vibration - Vibration testing requirements for shipboard equipment and machinery components. Practical guidance for measurement at the workplace.
Test procedure are described in detail and test log samples along with a polar diagram for evaluating the test results are furnished. They have largely replaced soft-bearing machines.
It covers both soft-bearing balancing machines and hard-bearing balancing machines. Annexes B to F are for information only. Guidance as to the manner in which users should state their requirements is given in annex B. Balancing machine drive adapter flange dimensions f. Description and evaluation.
ISO 2953 1999-04
This International Standard gives requirements for the evaluation of the performance and characteristics of machines for balancing rotating components. Balancing machine spindle flange dimensions f. Characteristics of horizontal hard-bearing balancing machines are described which make such machines suitable for gas turbine rotor balancing. More info Full Description Characteristics of vertical hard-bearing balancing machines are described which make such machines suitable for gas turbine rotor balancing. Hard-bearing machines have been used for gas turbine rotor balancing for several years.
Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee. Processing Analysis and Presentation of Vibration Data. Performance requirements c. This document also delineates performance tests to ensure compliance with the document. Details of proving rotors, test masses and performance tests to be employed to ensure compliance with specified unbalance indicating capability are given.
If a technical problem occurs on this website. Welcome Log in Home contact sitemap Your Account. These tests are performed during acceptance of a balancing machine and also later on a periodic basis to ensure that the balancing machine is capable of handling the actual balancing tasks.
April Mechanical vibration. It contains revised and more detailedrecommendations for testing the capability of balancing machines, including outboard proving rotors and overhungtest planes. Coupled Industrial Machines. Technical requirements for such balancing machines are included, however, special features, such as those associated with automatic correction, are excluded.
Therefore it is applicable to rotors with rigid behaviour as well as to rotors with shaft-elastic behaviour balanced in accordance with low-speed balancing procedures. Test procedures are described in detail and test log samples along with a polar diagram for evaluating the test results are furnished. Specifications and verfication of balance tolerances.
