Investigation about the Strength of Plastic Gears : 4th Report ; Abrasion and State of Tooth Profile Change of Driven Nylon Gear

Abstract

When the nylon gear is meshed with the steel gear, the data is short that the nylon gear would be used the driving gear or the follower. Nylon gear should be used as the follower, because as the follower is the reduction gear, the contact ratio is less at the follower. But as the materials of nylon is expensive than the materials of steel, the nylon gear request the predominancy. In this report, the abrasion, the state of tooth form variation and the life for the nylon gear of follower was examined. And about these things, the nylon gear of driving was compared and examined with the nylon gear of follower. Then the characteristic of the nylon gear of follower was distinct.
