歯車におけるポリアセタールの低摩擦化の効果 : 第3報, フッ素樹脂を充てんしたポリアセタールホモポリマ

Polyacetal homopolymer is excellent in its wear resistance, mechanical strength, and so on, as is polyacetal copolymer, and it is a plastic which works well in applications to mechanical parts. Also in this plastic, the material in which friction was decreased has been developed, although insufficient evaluation has been made with regard to applications to gears. Because of this, in this study, as for the polyacetal copolymer reported already, gears were made of the polyacetal homopolymer in which friction was decreased by filling them with fluorine-containing resin, and by carrying out the operation test under various conditions. The wear and temperature of the teeth, the change in the tooth profile, the surface roughness of the teeth and so on were examined. The results were compared with the experimental results of the dears made of the polyacetal homopolymer without filling, and its usefulness was examined.
