Abstract: The torsional-crosswise coupling vibration model of a central symmtric reducer gear-transmission system is developed. The cyclical excitation is expressed in Fourier series, and the system dynamic response is calculated. The sensitivity of the system natural frequencies with respect to the output spring-suspension structure is analysed, and the influence of the spring-suspension structure on the gear dynamic load factors is studied by practical example analysing.
