Rotating Equipment Balancing Standards

A theoretical and practical understanding of unbalance and misalignment in rotating equipment is presented here. These two conditions account for the vast majority of problems with rotating equipment encountered in the real world.;Numerous examples and solutions are...

This ARP specifies those requirements of balancing equipment which make it suitable for the subject class of work. It specifies: a Sensitivity b Accuracy of indication of amount and angle of unbalance. c Ability to measure static unbalance unaffected by couple unbalance. d Machine...

This document specifies requirements and provides calculations for the permissible static and dynamic residual unbalances of rotating single tools and tool systems. It is based on the guideline that unbalance related centrifugal forces induced by the rotational speed do not harm the spindle...

This Data Item presents four procedures for the design of counterweights which, when fixed to shafts rotating with constant angular velocity, improve the balance of machines that incorporate single degree-of-freedom, planar, multibar linkage mechanisms. The frame shaking force† and/or...

This SAE Aerospace Recommended Practice (ARP) specifies a series of balancing machine proving rotors and related test weights as directly required for the evaluation of gas turbine rotor balancing machines.

Characteristics of vertical non-rotating balancing machines are described which make such machines suitable for balancing rigid unbladed gas turbine rotors or rotors with fixed, integral blades.

This SAE Aerospace Recommended Practice (ARP) specifies a series of balancing machine proving rotors and related test weights as directly required for the evaluation of gas turbine rotor balancing machines.

This recommended practice specifies those requirements of balancing equipment which make it suitable for the subject class of work. It will specify: a Sensitivity b Accuracy of indication of amount and location of unbalance c Ability to measure force unbalance unaffected by couple...

This SAE Aerospace Recommended Practice specifies a series of balancing machine proving rotors and related test weights as directly required for the evaluation of gas turbine rotor balancing machines.

This International Standard establishes, in English and in French, a vocabulary on balancing. An alphabetical index is provided for each of the two languages. A general vocabulary on vibration and shock is given in ISO 2041. NOTE Terms in boldface in the definitions are themselves defined...

This document specifies those requirements of balancing equipment which make it suitable for the subject class of work. It will specify: (a) Sensitivity, (b) Accuracy of indications of amount and angle of unbalance, (c) Ability to separate the Dynamic Unbalance into two planes and to...

This handy reference source, is a companion volume to the authors Engineers Guide to Pressure Equipment. Heavily illustrated, and containing a wealth of useful data, it offers inspectors, engineers, operatives, and those maintaining engineering equipment a one stop everyday package of...

This International Standard gives requirements for the evaluation of the performance and characteristics of machines for balancing rotating components. It stresses the importance attached to the form in which the balancing machine characteristics should be specified by the...

This document establishes general design criteria, tolerances, and limits of application for tooling, fixtures and accessories for mounting and driving gas turbine engine rotors on horizontal and vertical balancing machines. For your own safety, while using balancing tooling, regard...

Cavities formed by discs contained within a shroud, either of which may be rotating, are a common feature of turbomachinery. Associated design problems are typically the determination of the cavity air supply required to control temperature, and of the power required to overcome the drag...

This document proposes a method of algorithmic load balancing. It enables multiple, cooperating servers to decide which one should service a client, without exchanging any information beyond initial configuration. The server selection is based on the servers hashing client Media Access...

This Practice provides guidance for the application of instrumentation to monitor rotating equipment for machinery protection, enhanced performance, and predictive maintenance. This Practice describes the following: a. Typical applications for continuous on-line monitoring of...

Introduction This document is intended to describe, discuss, and clarify the API Standard Paragraphs (SP) Section 6.8 which outlines the complete lateral and torsional rotordynamics and rotor balancing acceptance program designed by API to ensure equipment mechanical reliability....
