Experimental Research on Noise and Vibration Level of Gearbox using Worm Face-Gear with Reverse Tapered Pinion

Order to study and determine the performance of a gear, one of the fundamental criteria of operation is to determine the gear noise. Comparison of acquired data on noise and vibration levels for worm gear reducers equipped with reverse tapered front, is an important indicator regarding the level of quietness in operation of these gears. This has become especially given the particular cone snail related to asymmetric flanks (?1=100, ?2=300). This paper presents some aspects obtained on an experimental basis, on the determination of noise and vibration level in operation of a gearbox with worm face-gear with reverse tapered pinion to a pair of steel-bronze materials, oil lubricated T90, with 1:47 transmission ratio.
