PROBLEM TO BE SOLVED: To improve performance for preventing discharge between tooth surfaces of a gear shape shaft coupling and thereby preventing electric corrosion.SOLUTION: A cylindrical pinion 2 having external teeth 21 is fastened to a rotary shaft 1 on an inner peripheral surface. A cylindrical sleeve 3 having internal teeth 31 faces an outer periphery of the pinion 2 and the internal teeth 31 engage with the external teeth 21 of the pinion 2. A conductive end cover 4 covering an axial end surface of the sleeve 3 is attached. A conductive wire 9 contacts with the pinion 2 and the end cover 4. The conductive wire 9 has flexibility and follows relative displacement between the pinion 2 and the sleeve 3. The conductive wire 9 electrically connects the pinion 2 with the sleeve 3.SELECTED DRAWING: Figure 1
【課題】歯車形軸継手の歯面間での放電を防ぎ電食を防止する性能を向上する。【解決手段】外歯21を有する筒状のピニオン2は、内周面で回転軸1に固着される。内歯31を有する円筒状のスリーブ3は、ピニオン2の外周に対向し、内歯31はピニオン2の外歯21に噛合する。スリーブ3の軸方向の端面を覆う導電性の端カバー4が取り付けられている。導線9は、ピニオン2と端カバー4に接触する。導線9は可撓性を有し、ピニオン2とスリーブ3の相対変位に追随できる。導線9は、ピニオン2とスリーブ3とを電気的に接続する。【選択図】図1
