Patent number: 10550285Abstract: A method for manufacturing a telescopic shaft including a male shaft and a cylindrical female shaft slidably connected to each other in an axial direction, in which an outer circumferential surface of the male shaft or an inner circumferential surface of the female shaft is coated with a resin coating layer, includes a coating step, a broaching step, and a cooling step. In the coating step, a powder coating material is attached, by a fluid bed dip method, on the outer circumferential surface of the male shaft or the inner circumferential surface of the female shaft which is heated in advance and the resin coating layer is formed. In the broaching step, the resin coating layer is caused to be thin by broaching before cooling of the formed powder coating material is completed. In the cooling step, the thin resin coating layer is cooled.Type: GrantFiled: November 10, 2014Date of Patent: February 4, 2020Assignee: JTEKT CORPORATIONInventor: Tomoya Nishida

Publication number: 20150251399Abstract: A resin film is caught in a meshing portion between a spline shaft and a toothed roller. The spline shaft has an adhesive applied to the surface of splines formed on the outer periphery of the spline shaft, and has been heated. The toothed roller is rotatable about a center axis that is parallel to a center axis of the spline shaft. The resin film is wound up around the outer periphery of the spline shaft while the resin film is pressed to be adhered to the surface of the splines by the toothed roller at the meshing portion along with interlocked rotation of the spline shaft and the toothed roller. Consequently, a resin coating is formed on the surface of the splines.Type: ApplicationFiled: February 27, 2015Publication date: September 10, 2015Inventor: Tomoya NISHIDA
