Transmission Error Measurements in Gearbox Development,

Abstract

There is a requirement to test gears for initial development, for production monitoring and for condition monitoring in service. Traditionally the first two have been carried out by a combination of profile, helix, pitch and bedding checks and the third by measuring vibration at bearing housings. Gear drives in aircraft applications present difficulties in checking due to high distortions in the light weight gear cases. The use of transmission error (single flank) checking can give useful information on accuracy of alignment in gearboxes as well as fundamental noise generation information. Problems arise with attempts to use grating systems in turboprops but helicopters have tooth frequencies in a suitable range.
