This paper deals with the radiated noise of strain wave gearing, which is a kind of K-H-V type planetary gears having features of lightweight and high reduction ratio. The vibration of Flex Spline (F/S), which is the element of strain wave gearing and has a thin circular cup, is considered as a main factor of the noise. The magnitude of sound power is expected to become large in proportion to the square of the amplitude of displacement of F/S in the radial direction theoretically. The displacements of 3 kinds of models are calculated using FEM. The vibration of F/S and the sound power are measured using the F/S fixed type experiment apparatus. It is confirmed that the relation between the vibration of F/S and the sound power are agreed well to the theory and the vibration of the F/S causes the radiated noise mainly. Moreover, the radiated noise with changing a rotary speed, a loaded torque and an assembly error are measured and examined. The influence of rotary speed and torque is characterized by dependence of the deformation of F/S. The noise become large with the increase of the assembly error, but the amplitude of displacement is not increased. This is analyzed by a resonance between F/S and experiment apparatus.
