Description
【考案の詳細な説明】 〔考案の利用分野〕 本考案は、遠心機のロータに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Use of the Invention] The present invention relates to a rotor of a centrifuge.
従来は第３図に示すように、２のシャフトと４のナット
の間に８の平ワッシャもしくはスプリングワッシャがあ
り、このワッシャを紛失したり、ワッシャのバネ性が強
いとナットの締め付けに要するトルクが大きなものとな
り、締め付け不足によるロータの異常振動を招く恐れが
あった。Conventionally, as shown in Fig. 3, there are 8 flat washers or spring washers between the 2 shaft and 4 nut. If this washer is lost or the washer has a strong spring property, the torque required to tighten the nut Is large, and there is a risk of abnormal vibration of the rotor due to insufficient tightening.
本考案は従来の欠点をなくし、ロータとナットの固定を
確実にするものである。The present invention eliminates the drawbacks of the prior art and ensures the fixation of the rotor and nut.
本考案は、ロータとナットの間にサラバネを設け、その
サラバネが脱落しないようにホルダとワッシャを工夫し
たものである。In the present invention, a flat spring is provided between the rotor and the nut, and the holder and the washer are devised so that the flat spring does not fall off.

止するものである。1 and 2 show an embodiment of the present invention. 1 is a rotor that rotates by a centrifuge, 2 is a shaft, 3 is a motor, 4 is a nut, 5 is a holder integrally fixed to the rotor 1, 6
Is a washer and 7 is Sarabane. The present invention is a holding means for holding the flat spring 7 between the rotor 1 and the nut 4, and providing a thin washer 6 on the flat spring 7 so that the outer diameter of the washer 6 is larger than the outer diameter of the flat spring 7 and holding the flat spring 7 and the washer 6. The upper inner diameter of the holder 5 is made smaller than the two to prevent the holder 5 from falling off.
６のワッシャは薄い金属板でも可能である。The washer 6 can be a thin metal plate.
本発明によれば、ロータとナットの間にワッシャがある
ためサラバネを紛失しない、またワッシャとナットの底
面の摩擦係数が少ないため、小さな締め付けトルクでも
大きな軸力を得ることができる。さらにナットを締め忘
れた場合、異常振動が発生し、ナットが増し締めされは
ずれなくなることがなくなる。According to the present invention, since there is a washer between the rotor and the nut, the Sarah spring is not lost, and since the friction coefficient between the washer and the bottom surface of the nut is small, it is possible to obtain a large axial force even with a small tightening torque. Further, if the nut is forgot to be tightened, abnormal vibration will occur, and the nut will not be tightened further and will not come off.
