Vibrational characteristics of developed harmonic reduction gear and fault diagnosis by campbell diagram

摘要

This paper introduces dynamic characteristics of the developed harmonic reduction gear, namely KCSF-20 through the vibrational and structural analysis. Considering the modal testing, the developed harmonic gear was evaluated by comparing with THK product, CSF-20. The Campbell diagram was an useful tool to diagnose fault cases through analysing the vibrational characteristic of the harmonic reduction gear.
