向上させている。1 (A), 1 (B) and 1 (C) are a sectional view, a plan view, and an external view of a conical member applied to a centering member of a rotating body supporting device according to an embodiment of the present invention. In the figure, reference numeral 10 denotes a rotating body shaft supporting device, 11 denotes a rotating shaft, and a key.
A support 13 is provided via a rotating body 12 and a rotating body 15
Is arranged. In this embodiment, the rotating body 15 is described as a pulley around which a connected object (not shown) such as a tension band is wound.
The support 13 has a screw hole 13a at a position distant from the rotation axis, and a flat portion 13b is formed above. Reference numeral 14 denotes a centering member, which is formed by a conical conical member 14a, a bolt through hole 14b, and a shaft insertion hole 14c, and a thread winding body 17 is passed through the through hole 14b. Furthermore, the screw winding body 17 has a shaft
It is composed of a screw portion 17a to be attached to 11, a press-in locking portion 17b for press-fitting the conical member 14a, and a removal locking portion 18 to be similarly removed. Reference numeral 15 denotes a rotating body, which is formed by three parts, namely, a belt groove 15a, a plane part 15b, and a seat part 15c.
5a has a V-groove, the flat portion 15b has a plurality of elongated holes 15e oriented in the same direction, and the receiving portion 15c has a conical opening 15f coaxial with the rotating shaft 11. In addition, the support is in the long hole 15e.
A bolt 16a for fixing the rotating body 15 is provided between the screw hole 13a and the thirteenth screw hole 13a. FIG. 1 shows a normal operation state in which the rotating body 15 is disposed coaxially with the rotating shaft 11 on the support 13. FIG. 1 (B) shows a state in which fixing bolts serving also as four sliding guides are arranged. FIG. 1 (C) is a perspective view of the conical member 14a of the centering member 14, in which the rotating body 15 is kept coaxial with the rotating shaft 11 with only a single screw winding body 17, and complicated mounting and
Corresponds to removal. The conical member 14a is provided with slits 14f and 14g on the upper and lower sides to improve centering accuracy.

部材14自体は、回転体15および軸11との間に強固に摩擦
伝達する必要はなく、センタリング機能が維持すれば良
いので、密着性は弱く、単一のネジ巻上体17の操作だけ
で、センタリング部材14の着脱は容易である。In this manner, the conical member 14a of FIG. 1 (C) is different from a known fastening member in that one end of the shaft insertion hole 14c is closed by the closed holding portion 14b and the screw winding body 17 is held at the shaft center position. . Normally, the rotating body 15 is maintained coaxially with the shaft 11 by the centering member 14, but the power transmission itself is performed by the fixing bolts 16a,
It is transmitted at 16b. Therefore, in this example, the centering member 14 itself does not need to firmly transmit friction between the rotating body 15 and the shaft 11, and it is sufficient that the centering function is maintained. The centering member 14 can be easily attached and detached only by operating the body 17.

FIG. FIG. 7A shows the state after the centering member is removed, and FIG. 7B shows the state after the rotating body 15 has eccentrically slid after the fixing bolt 16a has been loosened. In the figure, reference numeral 22 denotes a drive shaft, and reference numeral 21 denotes a drive rotating body. The drive shaft 22 is a shaft of a prime mover (not shown) such as an electric motor.
連結物20が張帯類の場合の交換の手順は次のとおりで
ある。The procedure of replacement when the connected object 20 is a cord type is as follows.

体17と、回転体15の逆錐状開口15fとの三つの構成要素
によって、第一ステップの回転体15に加わる押圧力に抗
して回転体15を摺動する巻上摺動装置30が形成される。First, among the plurality of fixing bolts shown in FIG. 1B, the bolt 16b is removed, and the bolt 16a is loosened to some extent. In this state, the centering member 14 is then moved to the screw winding body 14.
As a result, the pressing force of the connecting body 20 is always applied to the rotating body 15 in advance, so that the rotating body 15
15 starts sliding on the support 13 in the direction of the drive shaft 22 due to the pressing tension. At this time, a part of the inverted conical opening 15f of the rotating body 15 is formed by the inclined portion 14g of the conical member 14a of the centering member 14.
The rotary member 15 eccentrically slides on the support member 13 in proportion to the withdrawal amount of the conical member 14a while contacting a part of the support member with the action of the pressing tension. Therefore, in this embodiment, the conical member 14a, the screw winding body 17 for pushing and removing the conical member 14a, and the inverted conical opening 15f A hoisting sliding device 30 that slides on the rotating body 15 against the pressing force applied to the rotating body 15 is formed.
従って、センタリング部材14を取外すと、第２図
（Ｂ）のように連結物20は回転体の外周との間に長さｌ

連結物20の取外しが可能である。Accordingly, when the centering member 14 is removed, as shown in FIG.

Is again loaded on the rotating body 11 by the screw winding body 17. Then a distance r 1 in the direction centering member 14 to wound while the connecting member 20 'to impart new pressing tension to the rotating member 15 in response to tightening of the screw winding body 17 slides as the second step Finally, the center axis of the rotating body 15 coincides with the axis of the shaft 11.

By tightening 16a and 16b, the exchange of the number of tension strips 20 'is completed. Therefore, the connection 20 can be changed without moving the shaft 11 at all, and at the same time, appropriate tensioning can be achieved. At this time, it goes without saying that the above description can be applied as it is even when only the rotating body 15 is replaced.

30として作用する。FIG. 3 is a sectional view of an apparatus according to another embodiment of the present invention. In the embodiment of FIG. 1, the sliding direction with respect to the support 14 is restricted to one direction because of the presence of the elongated hole 15e. If the load device (not shown) can be rotated manually, it can be handled, but if it cannot be rotated, it cannot be handled. Therefore, in the case of FIG. 1, the key 12 is removed between the support 13 and the rotating shaft 11 and the clearance is fitted so that when the centering member 14 is removed, the support 13 is separated from the rotating shaft 11 separately. And the rotating body 15 can be rotated together independently of the shaft 11, and can be easily modified. On the other hand, in this embodiment, since both the support 13 and the rotating body 15 are separately fixed to the rotating shaft 11 by the centering member 14 and the key 12, respectively, there is an advantage that the rotating body 15 can cope with any direction. There is. Also support
A falling-off prevention device 19 is provided below the flat portion 13a of the thirteen. The rotating body 15 is divided into a transmitting body 15a as a connected object and a disk 15b and connected by bolts 29. The disk 15b may have a rim shape. This prevents the rotating body 15 from being naturally removed or dropped even when the rotating body shaft supporting device 10 is mounted upside down. Further, unlike the example of FIG. 1, this embodiment shows an example in which the centering member 14 performs not only a different centering function but also a power transmission function between the rotating body 15 and the shaft 11, so that the member 14 itself is a wedge member. 14
f and the press-fitting member 14d, so that the conical member 14a of the member 14f is further press-fitted at the wedge portion 14e of the member 14d.
After loading the member 14f into the groove 11a with the small diameter bolt 17a, the bolt 17a is removed and the member 14d is press-fitted with the member 14d. Extraction is first member 14d
Then, a bolt (not shown) having a diameter larger than that of the bolt 17a is screwed into the thread groove 14b of the member 14f, and is pulled out while being in contact with the tip of the shaft 11. During operation, the small-diameter bolt may be fixed to the thread groove 11a, or the bolt 17b may be provided without mounting it as shown. Therefore, in this embodiment, a small diameter
The large diameter bolt forms the first screw winding body, and the bolt 17b forms the second screw winding body. The former performs the centering mechanism, and the latter performs the power transmission function. Also in this case, the first screw winding body, the conical member 14a, and the inverted conical opening 15f
Acts as 30.
また、この実施例でセンタリング部材14を第１図の例

着ボルト16を施すことが必要であることは言うまでもな
い。In this embodiment, if the centering member 14 does not have a power transmission function as in the example of FIG. 1, it goes without saying that it is necessary to provide fixing bolts 16 indicated by dotted lines.
