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 |
