Abstract
Recently, plastic gears have been used in water, but depending on the kind of plastic, there are some gears which show a great deal of wear when they are used in water. However, it is important to note that in water or in places where moisture exists, water functions as a lubricant, and wear decreases as compared with the case without lubrication. To date, some reports have addressed this phenomenon but few have presented data on the design of plastic gears for use in water. In light of this situation, in this study, nylon gears and polyacetal gears, which are widely used plastic gears, were operated in water and with a small number of water drops, and various characteristics such as the wear of the teeth, the change in the tooth profile, the tooth surface roughness and so on, due to the difference in the quantity of bathing water were examined.
