Therefore, if the bolt 53 is rotated too tightly when the 1294018 is connected, the shaft 55, the rotating body 54, and the push-out surface will be bitten. Death is not easy to remove (demolition). The improved type of the connecting device is the connecting device 6 shown in Fig. 5 (see Patent Document 1). The connecting device 60 includes an outer ring 62 having a cylindrical outer peripheral surface that is aged from the inner side of the wheel, a push-shaped inner peripheral surface, and a small-diameter side formed on the inner peripheral surface of the push-out shape and from the outer side. The flange portion 66 fitted to the shaft 65, the cylindrical inner circumferential surface formed on the large-diameter side of the push-out inner circumferential surface, and the enlarged diameter flange portion 67 formed on the large-diameter side end portion of the push-out inner circumferential surface a slit (not shown) in the axial direction; the inner ring 61 has a cylindrical inner peripheral surface fitted to the outer side of the vehicle from the outer side, and the outer ring 62 is pushed to the skin; The outer peripheral surface of the outer peripheral surface of the draped shape is in a push-out shape. (4) The cylindrical outer peripheral surface on the large-diameter side of the push-out outer peripheral surface and the cylindrical surface of the outer 裒 62 is formed in the push 峨^ ^ The enlarged diameter flange portion 68 of the end portion is formed in the axial direction hole of the enlarged diameter flange portion 68 and the slit (not shown) in the axial direction; and the hole in the direction of the bolt 63 is screwed to the rotating body. 64 screw holes. According to the connecting member 60, since the flange portion 68 is integral with the inner ring and the screw hole for removal is provided in the flange portion 68, it is easy to perform the work. In addition, since the work of the section 58 of the middle portion of Fig. 4 is not required, it is not necessary to apply a step difference to the number of holes of the rotating body 64, and it is necessary to have a circular hole shape. Therefore, the machining capacity of the hub hole is only processed with precision holes. Also, in the installation of the rotation ... won't care to apply high directionality. Furthermore, it is possible to guide the rotation on both sides of the push-out surface:: Think of it 65 for centering. Xia 64 and shaft 1294018 Next, the connection of 16 is 7〇, including: outer ring 72, which has a cylindrical outer peripheral surface from the Π:: wheel hole, and a push-shaped inner peripheral surface, and the inner ring 71 ' The outer peripheral surface of the outer peripheral surface of the cylindrical outer peripheral surface of the outer ring 72 and the outer peripheral surface of the outer peripheral surface of the push-out outer peripheral surface are expanded. a flange portion Μ and a shaft hole formed in the enlarged diameter flange portion 78; and "73, which is formed in the axial direction hole formed in the inner ring 71 and screwed into the screw hole 0 formed in the outer ring 72" The connecting member 7G prevents the movement of the rotating body 74 by abutting the end surface of the end plate of the rotating body 74: the edge portion 78. Therefore, the right screw is enlarged, and the locking force of k 73 is Only the outer ring 72 is moved toward the rim side of the flange portion, and the position of the rotator 74 is not changed. [Patent Document 1] Japanese Patent Laid-Open No. Hei 4 638 〇 公报 然而 ' ' ' 图 图 图 图 图 图 图 图 图 图 制造The shape of the inner ring 61 is fixed to the shaft first. Therefore, the tighter the bolt is locked, the more the rotating body "and the outer ring 62 will move toward the flange portion 68. Further, in the coupling device 70 of Fig. 6, since the bolt 73 enters the outer ring 72, it is necessary to increase the inner diameter of the hub hole, and as a result, the rotating body 74 is made larger. [Invention] The present invention has been made in view of the above problems. Further, an object of the invention is to provide a coupling for a shaft and a rotating body, comprising a hub hole, comprising: an inner ring having a cylindrical inner peripheral surface fitted to the shaft from the outer side, and a push-like shape The outer peripheral piece and the outer ring have a cylindrical outer peripheral surface 1294018 fitted to the hub hole from the inner side, and the push-out outer peripheral surface of the ring is matched with each other and is pushed into a circle on the small meniscus side of the push-shaped inner peripheral surface. The inner peripheral surface of the cylindrical inner peripheral surface and the small-diameter side end portion of the second inner peripheral surface are formed in the axial direction of the β-thickness portion, the enlarged diameter flange _ direction hole, and the thread are passed through the / In the screw body of the rotating body 〇p tired & in accordance with the present invention 'by the flange and the outer ring integrated shape, because the inner ring is first fixed to the shaft, so the gravity, the complex gentleman At - Β疋 Move the axis of the basket ^ I... Gu Yi’s position during the installation of the link is used for life and death. The efficiency of the connection work. In addition, because the bolt is not in the exterior, it can be directly connected to the rotating body in a more compact design, and the coupling is provided under the tapping hole of the outer ring. Figure 1 shows the shaft and rotation of the present invention. This connection has 1G, including the directional cross section 1 of _ 2λ U, and the inner ring I has a ring 30 and a snail. Check 40. As shown in Figure 12, and the inner peripheral surface 24 of the push-pull shape (the diameter is slightly larger than the slit 23 which penetrates the axial direction (refer to the figure: the other 'this inner ring 2. 'Outer ring 3〇, including: slightly smaller than the rim of the rotating body 14 ° ° 31 (its diameter, by; & H internal), and the inner ring 20 and the outer peripheral surface 22 The inner peripheral surface η of the pull-out inner peripheral surface η, the cylindrical inner surface of the small-diameter side: the small-diameter side end portion of the split-shaped inner surface 32 (four) (four) the rim portion-shaped inner circumference 1 36 at the flared flange portion 36 , I294〇i8 does not have the ability to insert the bolt 40. Figure 2). Shaft direction hole 37 and decomposition screw hole 38 (see also ring 3 0, and right also + / 33 ^ 32 ° rr ^ ^ l3 (!MW 3) near the crotch portion 36. The end portion extends to the enlarged diameter flange using the above-mentioned connecting gentleman and n is as follows. ~, 1〇' is used to connect the wheel 2 and the rotating body 14 to be processed. Between the hub hole 15 and the screw hole ”, as shown in FIG. 1 , the bolts 4 装入 are inserted into the joint body 14 and the shaft 12 . At this time, the circle of the lock 20 is made by the tolerance and the predetermined joint torque. The relationship between the inner peripheral surface 24 of the cylindrical shape and the open shape of the inner ring 4, the outer surface of the inner ring 4 zr axis, the surface of the inner ring 20 is fixed, and the position of the inner ring 20 is fixed. The cylindrical outer peripheral surface 3 is formed between the inner peripheral surface 16 of the wheel hole 15 and the surface genus. Re-entry _: 14' does not accompany the movement of the rotating body, but only one, when locking: move the respective push-out faces 22, 32 to engage, by changing the two inner rings 2. And the side of the rotating body 14 generates a locking force. That is, the shaft 12 side and the inner ring 2 are. Between the cylindrical inner peripheral surface 24, the rotating body = the outer circumference: the inner circumference S 169 of the 与 and the cylindrical outer peripheral surface 31 of the outer ring 3G, the wedges of the holes 22, 32 act to generate a locking force, Because of this, the shaft 12 and the rotating body can be pressed by the surface pressure. Because of this, the torque can be transmitted by friction. When the connection of the bulls is to be broken down, remove all the bolts 40 or the same size of the bolts and the price of the king. The screw is inserted into the screw hole 1294018. Abutting against the rotating body i 4 , a force for separating the rotating body 4 from the outer ring 30 is generated, and since the inner ring 2 is provided with the shaft T penetrating the slit 23, the original locking state is The garment 20 in the expanded state is restored to its original shape after the lock is released, and can be easily pulled out. Further, in the screw hole 38 for disassembly, a balance weight can be attached in response to high-speed rotation. In the above description, although the connecting device of the present invention has an inner ring and a ring, the present invention is not limited thereto, and may have a slit in any of them, and may have a slit. Further, regarding the shape of the slit, the through slit or the slit to the middle can be appropriately selected. According to the present invention, since the flange and the outer ring are integrated, the movement of the rotating body at the time of joining is eliminated, so that the alignment of the connecting device can be easily performed. As a result, Can greatly improve the efficiency of the work. In addition, since the bolts are not attached to the outer ring but are directly coupled to the rotating body, a more compact design can be employed. _ Furthermore, the coupling can be easily removed (removed) by providing a screw hole for disassembly in the outer ring.
