Experimental Research on Vibrations of Double Harmonic Gear Transmission
Journal Title: Analele Universitatii "Eftimie Murgu" Resita. Fascicula de Inginerie - Year 2017, Vol 24, Issue 1
Abstract
Gears transmission can be important sources of vibration in the me-chanical system structures and can have a significant share in the overall vibration level. The current trend of significant increase in pow-ers and speeds transmitted by modern mechanical systems, along with the size reduction, may cause a worsening of the behaviour of trans-missions with gears in terms of vibration, especially when the optimiza-tion criteria were not respected in the design, execution and installation phase. This paper presents a study of vibrations that occur in a double harmonic gear transmission (DHGT), based on experimental research. The experimental researches revealed that in a double harmonic gear transmission the vibrations are initiated and develop in the multipara harmonics engagement of the teeth and in the kinematic couplings ma-terialized between the wave generator and the flexible toothed wheel. These vibrations are later transmitted by means of the shafts and bear-ings to the transmission housing, respectively, through the walls of it, propagating in the air.
