Claims (1)
回転させるモータとが、シヤフトにより接続され
ている遠心機駆動部において、シヤフトの上端に
あるクラウンの内側に軸受を設け、クラウンと軸
受の間に、径方向に伸縮可能な、可動片を設ける
ことにより、低速回転域ではスリーブでクラウン
と軸受を支持し、高速回転域では遠心力によつて
スリーブが軸受より離れるようにすることで、回
転系の一次危険速度における共振を避けることの
できる遠心機駆動装置の防振軸受。 In a centrifuge drive unit in which a rotary container containing a sample for separation and a motor for rotating it are connected by a shaft, a bearing is provided inside the crown at the upper end of the shaft, and between the crown and the bearing, By providing a movable piece that can expand and contract in the radial direction, the sleeve supports the crown and bearing in the low-speed rotation range, and the centrifugal force causes the sleeve to separate from the bearing in the high-speed rotation range, thereby improving the rotation system. Anti-vibration bearings for centrifuge drives that can avoid resonance at primary critical speeds.
