問題点があった。By the way, the measuring chamber in which the rotor is accommodated has a structure in which a casing is divided into at least two parts in order to accommodate one rotor, and is composed of a casing body and a lid body, each having a dividing surface in a direction perpendicular to the direction of the rotation axis. Equipped with therefore,
The bearings that support the rotating shaft of the rotor need to be formed in two places, the casing body and the lid, with high precision, and this high precision machining not only increases costs, but also increases the cost of weighing the rotor. Rotor drive tests and adjustment tests can only be carried out in a room covered by the assembly body and lid, which is extremely inconvenient, inconvenient, and inefficient, and also requires work such as maintenance or rotor repair/replacement. However, there were many problems in that the procedure after removing the lid was extremely troublesome and could not be carried out efficiently.

The precision machining of the bearing part is only required on one side, and the rotor assembly operation is simple and efficient, which prevents high costs and eliminates work such as rotor rotation adjustment, maintenance, or rotor repair/replacement. We can expect direct effects such as making it extremely simple.
