【実用新案登録請求の範囲】[Scope of utility model registration request] 駆動モータの回転子軸の両端をころがり軸受で支持して
なる高速回転駆動装置において、上端のころがり軸受に
て上部回転体の全重量を支え、下端のころがり軸受にお
いてその回転体の荷重を軽減する方向に予圧バネが設け
られていることを特徴とする高速回転駆動装置。In a high-speed rotation drive device in which both ends of the rotor shaft of a drive motor are supported by rolling bearings, the rolling bearing at the upper end supports the entire weight of the upper rotating body, and the rolling bearing at the lower end reduces the load of the rotating body. A high-speed rotational drive device characterized in that a preload spring is provided in the direction.
