There was an inconvenience that could have been the cause.
更に、上述の(3)の方法においては、空気を吸い込む
方式であるため、真空になっても最大1kg/c++!
以上の気体の流れを発生させることはできず、軸の穴に
対する求心力は限定され、効果的に芯合わせを行なうこ
とが困難であるという不都合があった。Furthermore, in method (3) above, since air is sucked in, even if it becomes a vacuum, the maximum weight is 1 kg/c++!
It is not possible to generate the above gas flow, and the centripetal force against the hole in the shaft is limited, making it difficult to perform centering effectively.
本発明は上記に鑑み創案されたもので、その要旨とする
