Investigation about the Strength of Plastic Gears : 5th Report; Abrasion of Nylon Gear due to the Difference in Materials of Mating Gears.

Abstract

In the no lubricant operation, it is believed that a stainless steel gear, a brass gear and a cast iron gear are better applicable as the mating gears of nylon gears for rust prevention, than a carbon steel gear. But the abrasion of nylon gear when the nylon gear meshes with these gears is not clear, because these gears have been little used. In this report an abrasion experiment of nylon gear, which meshed with these three metallic gears, was performed. And the abrasion of nylon gear in this experiment was compared and examined with the abrasion of nylon gear in the earlier report, which meshed with the carbon steel gear. The abrasion of nylon gear when the nylon gear meshed with three different materials gears has been made clear.
