Improper aligning of shafts often leads to transmission error, which causes severe vibration problems in many rotating machines. Misalignment condition is always present in gear driving system for practical applications. In this study, nonlinear dynamic characteristics of the gear driving system due to misalignment were investigated. The results showed that the gear meshing stiffness was decreased but transmission error was increased in case of misaligned gear. Transmission error was calculated for spur gear and bearing stiffness was also calculated. The relationship between force and displacement showed linearity, but one of force and stiffness showed nonlinear shape. A gear driving system was modeled and the gear signal was investigated in the cases of perfect alignment, misalignment, and bearing-housing deformation.
