本考案は、動バランスを必要とする回転軸、た

回転軸をバランス修正する回転軸のバランス修正
装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotating shaft balance correction device for correcting the balance of a rotating shaft that requires dynamic balance, such as a long shaft whose both ends are supported by couplings.

は、該回転軸の内周面はそれほど精密な仕上げ加
工をせず、外周面のみ精密な仕上げ加工を施して

作ができなくなり、必然的に回転軸のバランス修
正を行なう必要性がでてくる。 Generally, when manufacturing a long hollow rotating shaft, the inner circumferential surface of the rotating shaft is not precisely finished, but only the outer circumferential surface is precisely finished. Therefore, there are some differences in the wall thickness of the rotating shaft in the axial direction, and as a result, when the rotating shaft is rotated, shaft vibration will occur and normal rotational movement will not be possible. There will be a need to correct the balance.

調整おもりとしてボルトを取付けてなるものが開
示されている。 Conventionally, as a balance correction device for a rotating shaft, for example, in Japanese Utility Model Application No. 53-35390, a balance adjustment ring was attached to the outer circumferential surface of the rotating shaft with screws, and the ring was adjusted to any desired position. A device is disclosed in which a bolt is attached as a weight.

転軸を回転させた場合非常に危険になり、回転軸
のバランス装置としては安全性に欠けるという宿
命的な欠点があつた。 However, in such a device, the head of the bolt serving as the adjustment weight protrudes from the outer circumferential surface of the balance adjustment ring, making it very dangerous when the rotation shaft is rotated. As a balance device, it had the fateful drawback of lacking safety.

ので、これらの取付け作業はさらに一層面倒にな
るという欠点を有していた。 Moreover, in this type of device, the attachment of the balance adjustment ring to the rotating shaft and the attachment of the adjustment weight for adjusting the balance of the rotating shaft are configured separately, so the work of attaching these is relatively troublesome. Not only that, but in order to balance the rotating shafts, it is necessary to take into account the mutual weight distribution relationship, which makes the installation work even more troublesome. It had

とにある。 The present invention was devised in view of these circumstances, and its purpose is to eliminate the above-mentioned danger during rotation of the rotating shaft, and to effectively and easily adjust the balance of the rotating shaft. An object of the present invention is to provide a device for correcting the balance of a rotating shaft.

したものである。 In order to achieve the above object, the rotating shaft balance correcting device of the present invention has two positions approximately 1/4 L from both ends of the rotating shaft that requires dynamic balance and has a shaft length L. A balance adjustment ring is fitted to the outer circumferential surface, and a fixing device such as a set screw is screwed into a predetermined position of this ring, with the upper end of the fixing device not protruding from the outer circumferential surface of the ring. The ring is fixed to the rotating shaft by pressing the tip of the fastening tool against the rotating shaft, and at the same time, the balance of the rotating shaft is adjusted by the weight of the fastening tool.
以下本考案に係る一実施例を図面を参照して説

It shows the state in which it is supported by coupling rings 2, 2 at both ends, and at a predetermined position of this rotating shaft 1,
Balance adjustment rings 3, 3 are attached.

一例であつて、回転軸１をバランス修正する状況
により、前記セツトスクリユー４の挿通する個所
および個数は適宜設定される。 As shown in FIGS. 2 and 3, the balance adjustment rings 3, 3 have an inner diameter that is approximately the same size as the outer diameter of the rotating shaft 1, and an axial center position that is similar to the rotating shaft 1.
The outer circumferential surface 3b has eight screw holes 3c formed at equal intervals in the circumferential direction and passing through to the inner circumferential surface 3a. Then, the ring 3 is placed at a predetermined position on the rotating shaft 1, that is, on the rotating shaft 1.
If the shaft length of the rotary shaft 1 is L, then two screws are fitted at 1/4L from the end surface of the rotary shaft 1, and
In order to adjust the balance, for example, set screws 4, 4 are screwed into two adjacent screw holes 3c, 3c as shown in FIG. 2 among the screw holes 3c.
The set screws 4, 4 are screwed in until their tip surfaces come into pressure contact with the outer circumferential surface of the rotating shaft 1, and the rear end surfaces of the set screws 4, 4 do not protrude from the outer circumferential surface of the balance adjustment ring 3, and the balance is adjusted. An adjustment ring 3 is fixed to the outer peripheral surface of the rotating shaft 1. Thereby, the balance during rotation of the rotary shaft 1 can be corrected by the weight of the set screws 4, 4 inserted into the adjacent screw holes 3c, 3c. However, the adjacent screw holes 3c, 3c
One example is that the set screws 4, 4 are threaded through the shaft 1, and the location and number of the set screws 4 to be inserted are appropriately set depending on the situation in which the balance of the rotating shaft 1 is to be corrected.

場合が生じてくることがあるが、この場合には前

てバランスの微調整をすればよい。 Note that after the balance adjustment ring 3 is fixed to the rotating shaft 1 using the set screws 4, 4, there may be cases where the balance of the rotating shaft 1 is further finely adjusted. Alternatively, the balance may be finely adjusted by drilling a hole in the balance adjustment ring 3 or by grinding it with a grinder or the like to reduce the weight.
また、前記バランス調整用リング３を、回転軸

位）に２個前記セツトスクリユー４，４でもつて

軸振れを最も有効に打ち消すことができるからで
ある。 Furthermore, the two balance adjusting rings 3 are fixed at a position approximately 1/4L from the end face of the rotating shaft 1 (precisely at a position 0.22L) using the set screws 4, 4. This is because shaft runout during rotation of the rotating shaft 1 can be most effectively canceled.
つまり、今回転軸１を梁と相定し、かつこれが
両端においてカツプリング２，２により支持され
ていると考えれば、回転軸１はその自重により中
央部で最大の撓みを生ずることになるが、この中
央部での最大の撓みを打ち消す最も有効な反力は

調整用リング３，３を前記セツトスクリユー４，
４でもつて固定させておけば、回転軸１の回転時
における軸振れは最も有効に打ち消すことができ
るのである。 In other words, if we consider that the rotating shaft 1 is now aligned with the beam and that this is supported by coupling rings 2, 2 at both ends, the rotating shaft 1 will experience maximum deflection at the center due to its own weight. The most effective reaction force to counteract the maximum deflection at the center is 0.22×L from both end surfaces of the rotating shaft 1, respectively.
Therefore, the balance adjusting rings 3, 3 are attached to the setting screws 4, 3 at these locations.
If the rotation shaft 1 is held fixed even by 4, the shaft runout during rotation of the rotary shaft 1 can be most effectively canceled.

回転させても冒頭で述べた従来のような危険性を
生ずることはなく、安全な回転軸のバランス修正
装置を提供できる。 As explained above, the rotating shaft balancing device of the present invention uses a fixing device such as a set screw that does not protrude from the outer peripheral surface of the balancing ring when fixing the balancing ring to the rotating shaft. However, since the rotary shaft is fixed, even if the rotary shaft is rotated, there is no danger as described in the prior art, and a safe balance correction device for the rotary shaft can be provided.

業を容易に行うことができる。 Furthermore, in the rotary shaft balance correction device of the present invention, the fixing device is used to both fix the balance adjustment ring to the rotary shaft and adjust the balance of the rotary shaft, so it is a separate component. Compared to a device that fixes the balance adjustment ring and adjusts the balance of the rotating shaft, it is possible to reduce the man-hours required to attach parts to the balance adjustment ring, and it is also a part that fixes the balance adjustment ring to the rotating shaft. It is not necessary to perform balance adjustment taking into account the arrangement state, weight, etc., and the balance adjustment work can be easily performed.

ス調整がさらに容易されるものである。 In addition, in the case of the present invention, the balance adjustment ring is placed at the most effective position to cancel the maximum deflection at the center of the rotating shaft, that is, at two positions on the outer peripheral surface approximately 1/4 L from both ends of the rotating shaft. Since the balance adjustment ring is fixed to the outer circumferential surface of the rotating shaft using a fixing device, not only can balance adjustment be performed effectively, but also the balance adjustment ring can be fixed at its mounting position. When performing balance adjustment, it is only necessary to decide the number of fasteners and the position at which the fasteners are fastened to the balance adjustment ring, which further facilitates balance adjustment.

作用効果を奏する。 In the above embodiment, a case has been described in which the coupling rings 2, 2 are supported at both ends of the rotating shaft 1, but the present invention is not necessarily limited to such a case. For example, as shown in FIG. One end of the rotary shaft 1 may be supported by a coupling ring 2, and the other end of the rotating shaft 1 may be supported by a drive shaft 5. Even with something like this, balance adjustment rings 3, 3
By fixing the rotary shaft 1 to a predetermined position on the rotating shaft 1 with a fixing device such as a set screw 4, the same effect as described above can be obtained.
