Dynamic Analysis of the Inverted Tooth Chain Plates Moving Towards Sprocket

The investigation of the dynamic behaviour of the plates of an inverted tooth chain (used as driving system in a wide range of automotive applications) is still a research issue. The contact between the chain plates and the sprocket generates vibrations, with negative effect on the overall driving system performance. This paper aims to perform an in depth analysis of the behaviour of the chain plates contacting a sprocket at different moments, considering the Analogous Huygens Pendulum model and the plates movement towards the sprocket. A frequency domain analysis is performed. The study leads to a better understanding of various scenarios that a plate contacting the sprocket can produce and will allow future studies comparing similarities between a chain plate in a pendulum motion system and a chain drive motion system.
