  10-15 is a figure explaining the cleaning procedure of the spline hub performed using this embodiment. In FIGS. 12 to 14, the ring-shaped hollow plate 6 that forms one side of the whole is omitted.

  When the spline hub 1 is cleaned, when the cleaning device according to this embodiment is attached to the spline hub 1, as shown in FIG. 10, for example, a ring-shaped hollow plate that forms one side surface of the entire embodiment. The end 18 of the body 6 may be opposed to the end 34 of the spline hub 1, and the ring-shaped hollow plate-like body 6 may be inserted into the spline hub 1 as shown in FIG. 11. At this time, the inner diameter 3A of the ring-shaped hollow plate 6 is set to be approximately the same as the outer diameter 2A formed by connecting the tops of the peaks 2 of the spline hub 1. The plate-like body 6 can function as an entire guide member.

  After attaching the ring-shaped hollow plate-like body 6 to the spline hub 1 in this way, as shown in FIG. 12, the corrugated shape of the convex portions 8A and concave portions 8B of the corrugated ring hollow plate-like body 11, and the spline hub 1 If the trough 7 and the crest 2 are not compatible and cannot be inserted entirely, a plurality of ring-shaped hollow plates centering on the axis of the spline hub 1 as shown by an arrow 37 in FIGS. The entire structure including the corrugated body 6 and the plurality of corrugated ring hollow plate-like bodies 11 is rotated so that the convex portions 8A and the concave portions 8B of the corrugated ring hollow plate-like body 11 are connected to the valley portions 7 of the spline hub 1 as shown in FIG. And fit to each of the ridges 2.

  In this state, as shown by the arrow 38 in FIG. 14, the entire structure including the ring-shaped hollow plate 6 and the corrugated ring hollow plate 11 may be moved. As a result, the inner peripheral portion 3 of the ring-shaped hollow plate-like body 6 comes into contact with the peak portion 2 of the spline hub 1 so that the peak portion 2 of the spline hub 1 can be cleaned. 11 ridges 8B come into contact with the crest 2 of the spline hub 1 so that the crest 2 of the spline hub 1 can be cleaned. At the same time, the convex portion 8A of the corrugated ring hollow plate-shaped body 11 comes into contact with the valley portion 7 of the spline hub 1 so that the valley portion 7 of the spline hub 1 can be cleaned. Thereafter, as indicated by an arrow 39 in FIG. 15, the cleaning device according to the present embodiment is reciprocated on the spline hub 1 to further clean the spline hub 1 as necessary.

  By the way, when assembling the spline cleaning device as described above, as shown in FIG. 9 described above, it is necessary to appropriately bond together in a state where the spline cleaning device is rotated by a predetermined angle to obtain the laminated structure 17 shown in FIG. Therefore, for example, as shown in FIG. 16A, a plurality of insertion holes 40 are provided in advance in the ring-shaped hollow plate-like body 6 and the corrugated ring hollow-plate-like body 11, and as shown in FIG. The ring-shaped hollow plate-like body 6 and the corrugated ring hollow-plate-like body 11 are alternately inserted in the direction of the arrow 43 from the distal end side of the insertion rod 42 in which the insertion hole 40 is separately erected on the fixing plate 41, and FIG.

Deviation may occur in the inner diameter 3A of the plate-like body 6. If such a deviation occurs, a dimensional relationship with the spline hub 1 may occur during assembly, which may make it difficult to insert the spline hub cleaning device 44 into the spline hub 1 and thus cannot be inserted. Then, the spline hub cleaning device 44 cannot function as a cleaning device.

  On the other hand, as shown in FIG. 17, the hire 47 is manufactured by imitating the shape of the spline hub 7, and as shown in FIGS. There is also a method in which the ring hollow plate-like bodies 11 are alternately inserted in the direction of the arrow 48 and the spline hub cleaning device 1 is assembled as shown in FIG. In this case, after assembling, the spline hub cleaning device 1 is pulled out in the direction of the arrow 49 as shown in FIG. 4D, and the spline hub cleaning device 1 is removed from the hire 47, so that it can be used as the spline hub cleaning device 1. It becomes possible. FIG. 17 is a perspective view for explaining the assembly procedure.

  In this method, since the hiring 47 has the same configuration as the spline hub 1 to be cleaned, the shift described with reference to FIG. 16 does not occur, and accurate assembly is possible. Cost increases.
