本発明は、高速回転体の軸受振動荷重軽減方法に係シ、
特にバランスウェイトの付加によるバランス修正に関す
る。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a method for reducing vibration load on a bearing of a high-speed rotating body.
In particular, it relates to balance correction by adding balance weights.
高速回転体においては、従来から回転体の精密なバラン

ランス研削、もしくは、ねじを利用したバランス９エイ
トの付加が打力われている。For high-speed rotating bodies, precise balancing of the rotating bodies has been conventionally performed. If the vibration of the 11 rotation support shaft is large and the bearing vibration load is large, it is necessary to balance the rotation support shaft. In this case, balance grinding of the rotation support shaft or balance 9 eight using screws is required. The addition of this is a powerful addition.

合がある。[1 point about background technology] However, in the case of balance grinding, it is difficult to control the amount of grinding, and at the same time there are problems such as loss of accuracy of the shaft. If the shaft is thin, there may be problems with the phase accuracy or the inability to make minute corrections.

。In balancing a high-speed rotating body, the present invention attaches a hollow balance ring whose center of gravity is centered with respect to the center of the inner diameter, or a horseshoe-shaped balance ring with a part of the ring removed, to the rotation support shaft. It is characterized by what it did.

-, the center of the inner diameter and the center of the outer diameter are A-A in Figure 1.
As shown in FIG. 2, which is a cross-sectional view, a broken balun 2 ringer is installed.

とによって、修正量を自由に選択することができる。However, since the center of gravity of the balance ring 4L is damaged with respect to the center of the rotating shaft, an unbalanced force due to centrifugal force is generated, so that shaft vibration can be balanced. Further, according to such a scattering method, not only the phase can be freely selected, but also the amount of correction can be freely selected by changing the amount of eccentricity or length.

A part of the cylinder has been removed to form a window. In either case, the amount of correction can be controlled by the deletion process, as shown in FIG. 3(a).

つかかシが回転支持軸に詐けられている。Figure 6 shows an example of how to attach the balance ring 4I.
In order to avoid applying force to the entire J1 rotation support shaft, the press-fitting jig's hook is replaced by the rotation support shaft.

グを圧入装着することができる。tJA4I (Fig. 6L) is a structure in which an annular convex part is provided on the rotation support shaft, and Fig. 9 (1)) is a structure in which the outer diameter of the rotation support shaft is made smaller than the outer diameter of the rotation support shaft. 4 is crossed out. With this structure, we have 1.
The balun 2 ring can be press-fitted without affecting the accuracy of the 11-turn support shaft.

適する輔の効果を奏する。As explained below, by using the balance ring as described above, the balance of the rotation support shaft can be corrected with high accuracy. Furthermore, compared to adding the balance 98 by grinding or screwing, it is easier to make one piece, and it has the effect of being suitable for connotation.
