Research on the rotation vibration in the transmission with gear box defects

Abstract

The article presents theoretical research of rotation vibrations in the transmission system. Transmission with an idle consists of electrical motor, gear box and connecting shafts. In the gear box some teeth have different size of the defects (0%, 20%, 50%, 80% of teeth width). In the dynamics model of gears, the deformation of each tooth and backlash between connection of the gear teeth are evaluated. The dynamics of the transmission is described using finite element method and discreet elements. The paper presents and analyses the results of mathematical experiment on this system.
