Abstract
In this study a power transmission spur gear is recommended as a profile corrected spur gear. Supposing it is allowable that the given value deviates about ten-odd percent from actual acceleration, it is synthesized how a tooth profile error with waved form influences the rotational vibration of a profile corrected spur gear, using a simulator developed by authors. The influence degrees are revealed in an influence chart in which they are determined in relation to a rotational speed and a contact ratio. According to the result, the performance of spur gears having a waved form error is closely related to the speed but not associated with contact ratio. Especially at high speed a gear having this error is not recommendable, because this type of error influences adversely the rotational vibration of the gear at high speed.
