Use of simulation and laboratory tests to shape the vibroactivity of toothed gears

Vibroacoustic phenomena occurring in power transmission systems affect the durability and quality of the driven devices, and also allow for evaluation their technical condition. The article presents the results of laboratory tests aimed at comparing the vibroactivity of the toothed gear, in which the pairs of wheels differ in geometric parameters. The results of research carried on test stand are supplement with results of computer simulations. The proposed test method can be used to determine general vibration and noise reduction guidelines for power transmission systems with toothed gear. The results of the numerical and laboratory tests carried out at the transmission system with circulating power system show that the uncomplicated transformation of the gear geometry used in the toothed gear from the manufacturing point of view allows to reduce the level of vibroacoustic phenomena accompanying their work.
