Investigations on the Accuracy of Molded Spur Gears of Nylon
Journal of the Japan Society of Precision Engineering, 1961 以上の結果より一般にマルチゲートにより方向性の少ないものを得ることが期待出来る。しかしながらゲート位置やその向ぎ,また各ゲート問の樹脂の流れにたいするバランスなどが適切であることが必要である。また歯車円板部の外周近くに存在する突起や穴は真円性を害する原因となる場合がある。例えば最も良好な結果を得た試料IVといえどもカム突起の影響で著しく真円性が害なわれている。本論で扱つた試料においては真円よりの最大ずれで見た場合,成形方法がシングルゲートでもマルチゲートでも差はないといつてよい。しかしながらそのずれの性質は異なつており,その可否は要求機能により判断されるべきものであろう。

Bulletin of JSME, 1986 Two prevention methods are proposed in the previous report as the prevention methods of tooth profile change in the course of operation of a nylon gear which transmits the power. And their effect is confirmed by experiments. In this report as a method simpler than those methods, a plus profile shifting of nylon gear is proposed.
