(3-1) situation of the revolving force of forward direction is applied at drive source 70 pairs of rotating shafts 10
When drive source 70 pairs of rotating shafts 10 apply the revolving force of forward direction, rotating shaft 10 (revolution body 20) rotates to forward direction with rotary speed S1.
In this case, along with the rotating forward of rotating shaft 10, rotation power applies the revolving force that belt wheel 64 is applied in forward direction.At this, rotation power applies belt wheel 64 by driving-belt 68 and drive pulley 84, is associated in rotary speed with the second rotating shaft 82.Therefore, the second rotating shaft 82 is also applied in the revolving force of forward direction.But the second rotating shaft 82 restricting portion 88 restriction rotates forward.Therefore, the rotating forward that rotation power applies belt wheel 64 is limited and is in halted state.Namely the rotary speed S2 that, rotation power applies belt wheel 64 is 0rpm.
In addition, the second drive pulley 92, by driving-belt 12 and belt wheel 14, is applied in the revolving force of the forward direction from rotating shaft 10.But the second drive pulley 92 is limited due to the rotating forward of the second rotating shaft 82 (rotation power applies belt wheel 64), is therefore rotated forward independently with the second rotating shaft 82 by the effect of blocking unit 90.Namely, the second drive pulley 92 dallies relative to the second rotating shaft 82.Therefore, the transmission from rotating shaft 10 to the revolving force of the second rotating shaft 82 (rotation power applies belt wheel 64) is blocked.
At this, certainly turn 30 rotary speed S3 tried to achieve by formula 1.But, because rotary speed S2 is 0rpm, so rotary speed S3 is tried to achieve by the formula 2 this value brought into formula 1 and obtain.In addition, certainly turn 30 direction of rotation be reverse directions.
Formula 1
Formula 2
Based on more than, centrifuge 1 is when drive source 70 pairs of rotating shafts 10 apply the revolving force of forward direction, make accommodating container 50 centered by the axis L1 that revolves round the sun to forward direction with rotary speed S1 revolution, and centered by rotation axis L2 to reverse directions with rotary speed S3 rotation.
(3-2) situation of the revolving force of reverse directions is applied at drive source 70 pairs of rotating shafts 10
When drive source 70 pairs of rotating shafts 10 apply the revolving force of forward direction, rotating shaft 10 (revolution body 20) rotates to reverse directions with rotary speed S1.
In this case, rotation power applies belt wheel 64 and can rotate to reverse directions.This is because, applied the second rotating shaft 82 restricting portion 88 that belt wheel 64 is associated in rotary speed by driving-belt 68 and drive pulley 84 with rotation power and allow to reverse.
In addition, the second drive pulley 92, by driving-belt 12 and belt wheel 14, is applied in the revolving force of the reverse directions from rotating shaft 10.At this, the second drive pulley 92 is because the reversion of the second rotating shaft 82 (rotation power applies belt wheel 64) is allowed to, so reversed integratedly with the second rotating shaft 82 by the function playing blocking unit 90.Therefore, rotating shaft 10, by the second drive pulley 92 etc., makes it the revolving force reversed to the second rotating shaft 82 transmission.
Further, the second rotating shaft 82 reverses by being subject to the revolving force of transmission.Further, this revolving force is by drive pulley 84 and driving-belt 68, apply belt wheel 64 transmission from the second rotating shaft 82 to rotation power.Thus, rotation power applies belt wheel 64 and rotates with rotary speed S2 to reverse directions.
At this, the rotary speed S2 that the rotation power in this situation applies belt wheel 64 is tried to achieve by formula 3.
Formula 3
On the other hand, from turn 30 rotary speed S3 by bringing formula 3 into formula 1, the formula 4 that obtains is tried to achieve.At this, in centrifuge 1, be usually set as that rotary speed S1 is less than rotary speed S2.In this case, the value because of the rotary speed S3 tried to achieve by formula 4 is negative, thus certainly turn 30 direction of rotation be reverse directions.In addition, when rotary speed S1 is equal with rotary speed S2, rotary speed S3 is 0rpm.In addition, rotary speed S1 and rotary speed S2 is set as above-mentioned arbitrary situation, relevant with the stable Function of blocking unit 90.
Formula 4
Based on more than, centrifuge 1 is when drive source 70 pairs of rotating shafts 10 apply the revolving force of reverse directions, accommodating container 50 is revolved round the sun to reverse directions with rotary speed S1 centered by the axis L1 that revolves round the sun, and with rotary speed S3 rotation centered by rotation axis L2.
At this, in centrifuge 1, be usually set as that rotary speed S1 is less than rotary speed S2.The sense of rotation of the accommodating container 50 in this situation is reverse directions.In addition, when the rotary speed S1 of centrifuge 1 is equal with rotary speed S2, accommodating container 50 not rotation.
