Abstract

Directing to the failure of high speed gear pair, this paper investigates its failure mechanism. Based on the failure characteristics, this paper adopts the power spectrum and empirical mode decomposition to detect two types of gear tooth failures. Defects were intentionally seeded in two separate pinions to explore feasible approach to monitor the tooth condition in a high speed gear pair. The failure mechanisms, vibration mechanism of defected tooth are presented. The empirical mode decomposition is adopted to reveal the characteristics of pitting and broken tooth failure.
