And a hub 31 connected by a pair of circular sheets 36, 36, a pair of circular hubs are rotatably mounted on an axle 38. The left and right flanges 34, 34 were fitted, the rim and the hub body were joined by circular sheets from both sides with the flange width being the same as the rim width, and then the pair of flanges were expanded to expand the disk. Things
In particular, a pair of left and right flanges 34, 34 each having an annular and internally formed female thread are screwed to opposite male screws 32, 33 formed on the left and right sides of the outer periphery of the hub cylinder, and the flanges are connected to the shaft of the hub body. It can be expanded and moved in any direction.

In order to separate the hub cylinder from the disk portion where the rim and flange are integrated by a circular sheet, the hub cylinder and the flange are relatively rotated to widen the flange interval. The hub cylinder must be removed from the left and right flanges. However, since the flange has already been joined to the rim by a circular sheet to form a disk, the hub cylinder and the disk are separated from each other when the hub cylinder and disk are separated from each other. And it cannot be taken out from between the circular sheets of the disk part.

みが雄ねじ部を左側へと移動する。The hub according to the present invention has a small-diameter smooth surface portion on the outer peripheral surface and a slightly larger-diameter male screw portion provided with a male screw in one direction and a hub cylinder body which slides and fits only on the small-diameter smooth surface portion. Since it is composed of a flange and a female threaded flange having an internal thread on the inner peripheral surface that is screwed into a slightly larger diameter male thread part, when manufacturing a disc wheel by stretching a disc on the outer surface of the rim and the flange, first, the female threaded flange must be Then, the sliding flange, which is slidably fitted only on the small-diameter smooth surface portion, is set on the right side as shown in FIG. 3 with the small-diameter smooth surface portion of the hub cylindrical body. Slide the flange toward the left male thread and rotate both flanges around the hub cylinder. That is, if the male screw in one direction is a right-hand thread at this time, the hub cylinder rotates in a counterclockwise direction (arrow R direction). When turning, only the female threaded flange Along the axial direction of the hub tubular body moves is sent to the left (arrow A direction). On the other hand, the sliding flange slidingly fitted to the small-diameter smooth surface portion is prevented from moving to the left male screw portion side by a male screw portion slightly larger in diameter than the diameter of the fitting hole of the flange. Therefore, only the female threaded flange moves the male thread to the left.

ク間の接着剤を硬化させ、押さえ板で固定する。In this manner, the female threaded flange is disposed on the male threaded portion, the left and right flange spacings are made equal to the rim width, and the outer peripheral side surfaces of the pair of left and right disks are joined to both side surfaces of the rim. After applying the adhesive to the outer surfaces of both flanges on the side surfaces and rotating the hub cylinder counterclockwise, only the left female threaded flange is fed to the left.
By the way, since the pair of left and right disks are made of exactly the same material and have the same shape, each disk has a uniform working relationship with both flanges. Therefore, since the same tension is applied to the outer surface of the rim from the left and right disks, the rim is pulled by the left disk and moves in the same direction as the left female threaded flange moves. The amount of movement is one half of the amount of movement of the left female threaded flange. When the two flanges are spread at the optimum interval, the radial and axial deflections of the rim are properly corrected, and then the adhesive between the flange and the disc is hardened and fixed with a holding plate.

すことが出来ない。Further, a conventional hub structure in which male screws opposite to each other are engraved on the outer periphery of the hub cylinder body on the right and left sides, and the left and right flanges on which the female screws are engraved are relatively rotated to open and widen the left and right flanges. After completing the disc wheel by stretching a circular sheet that is a disc between the rim and the hub flange, even if the hub cylinder is removed from the hub flange as described above, the hub cylinder remains on the left and right sides of the disc wheel. Since it falls between the circular sheets, it cannot be taken out of the disc wheel.

To go to the right side,
The entire disc portion in which the disc is interposed between the rim and the flange can be inserted and removed from the hub cylinder.
