This paper presents a study on the dynamic behavior of three types of spiral bevel gears, which have different tooth profiles and tooth bearings. The circumferential, radial and axial vibration accelerations of gear bodies, the gear noise and root stresses were measured under different running conditions by using a gear testing machine of a power absorbing type. The contact ratios of these spiral bevel gears were obtained from the measured results of root stresses. The vibration accelerations and the noise of the spiral bevel gears were found to decrease with increasing area of tooth bearing and to be almost equal irrespective of the drive side (convex side or concave side) of the gear tooth. They tended to increase with increasing gear speed but to be almost equal irrespective of the applied torque used in the range of this experiment. The maximum root stresses of these gears were found to be almost equal irrespective of the gear speed used in the range of this experiment.
