Accuracy of small encoders for gear transmission errors

Abstract

For noise investigations and development work or precision production control of gear drives there are major advantages to using small encoders for transmission error measurement in situ owing to reduced size, inertias and cost. As there was uncertainty concerning the accuracies that would be obtained in practice, a small encoder was calibrated and found to be surprisingly accurate at those frequencies of importance for gear noise.
