Dynamic loads on spur gear teeth are examined by a gear testing machine and a strain gauge apparatus. The ground pinion and gear are tested at the periphery speed 80 m/s and below. Some teeth of the gear have normal pitch errors which were given about 15μ on purpose. The magnitude of the dynamic load increases at the critical speed at which the conjugating frequency is equal to the natural frequency of the vibratory system consisting of the pinion, gear and the teeth stiffness. At a speed higher than the critical speed, the heavy dynamic load occurs on the tooth which has the postitive error. If there is a tooth which has the negative error, the tooth tends to carry no load, and the heavy dynamic load will occur after several teeth. The calculated results, which are analysed as a vibration problem, are nearly coincident with the measured results.
