Summary:The friction loss and noise of gears has been studied for along time, but it has not yet been made clear. Moreover, JIS gear accuracy class is not necessarily linked with the performance operation of gears, and hence it is important to find the relations between the tooth form accuracy and performance of gears. In the present study, we carried out the experiments to obtain the influence of tooth profile error on the friction loss and noise of spur gears. Nine kinds of tooth profile error with grinding with the similar error amount were used and also we prepared a barrel polished gear which had tip relief by grind. Test results showed that tooth profile error shapes affect the friction loss and noise very much even if the amount of error is the same. Further, it was found that the friction loss and noise have a certain correlation with each other and a barrel polishing showed the lowest friction loss and noise.
