STATIC BALANCING EQUIPMENT FOR JET ENGINE COMPONENTS COMPRESSOR AND TURBINE - ROTATING TYPE FOR MEASURING UNBALANCE IN ONE TRANSVERSE PLANE
1975-01-01
HISTORICAL
ARP588A
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 capacity relating to weight and physical dimensions of the rotors which can be balanced. e Balancing speed of rotation. f Standard balancing machine drive adapter flange dimensions. g Power requirements.

Horizontal Balancing Systems - Isolating Repeatability Issues in Challenging Applications
2023-06-05
CURRENT
ARP6911
This SAE Aerospace Recommended Practice will serve as a practical resource that offers guidance to both the machine operator and process engineer for isolating the source(s) of non-repeatability in measured unbalance data. The content of this standard addresses: Machine capability to achieve the specified unbalance tolerances and repeat within those tolerances. Tooling capability to repeat within the specified unbalance tolerances. Rotor characteristics that may preclude repeating within the required unbalance tolerances.

Balancing Machines - Verification Test Requirements
2020-08-25
CURRENT
AS8617
This document specifies instructions to verify proper calibration of all balancing machines used for processing gas turbine rotors. Detailed test procedures and test log samples are provided to evaluate the condition of the machine under test. These performance and test requirements may be used for new installations, periodic surveillance, or following repairs that may have affected machine performance. Calibration of the balancing machine is an activity done prior to verification testing and is outside the scope of this document. Troubleshooting of difficulties during the verification tests is also outside the scope of this document; this document is purely an instructive procedure.

Balancing Machines - Description and Evaluation Horizontal, Two-Plane, Soft-Bearing Type for Gas Turbine Rotors
2012-12-17
CURRENT
ARP587C
The specific performance requirements preceding each test in Section 9 have been written to define certain characteristics of the machine. Conformance with the tests constitutes what is considered minimum proof that the machine will meet these requirements. The test procedures will not prove conformance with all requirements over the full range of all variables, neither will they measure nor define the exact reasons for nonconformance in a given test. Failure of a machine to conform may be due to shortcomings in specific components or to more general reasons such as lack of ruggedness, improper leveling or anchoring to the floor, etc.
