Gear rattle of multi-step helical gear system is treated. Mesh stiffness variations are considered with in the system. The effects of mesh stiffness variations and the ratio of static torque to dynamic one on the rattle are studied by a highly accurate numerical analysis called the shooting method. As a result, the followings were made clear. (1) Because of the interaction of dynamic torque and mesh stiffness variation, resonances like gear noise occur in the low frequency region, and the number of them is equal to the product of the number of natural frequencies and number of gear steps. (2) In gear rattles of this type and other type which is generated due to a small constant torque in extremely low frequency, the rattle of the 1st stage is dominant. (3) Chaos occurs in the large frequency region as in single-stage gear system. The route to chaos is period doubling bifurcation.
