石炭酸樹脂の耐摩耗性の研究

抄録

In this report we made experiments on the abrasion resistance of phenol resin by the Amsler abrasion testing machine under the condition of water lubrication. Phenol resin applied to tests was the laminate of canvas base which is often used as machine parts, that is, bearing materials, piston rings, brake linings, silent gears, cams, rollers and etc. For comparisons sake expriments were made also on casted bronze under the condition of oil lubrication. In the abrasion tests the materials paired with the specimens were medium carbon steel and gray cast iron, which were rotated at the peripheral velocity of 0.5m/s, while the specimens were fixed. Experiments were made till the rubbing distance of about 302 kilometer, and amount of wear, frictional moment and temperature were measured. As the rerults, it was clearedt hat the abrasion resistance of phenol resin is very superior to that of casted bronze when the contact pressure is high.
