Specific embodiment
Specific embodiment 1: attached drawing 1 is the structural schematic diagram of one preferred embodiment of the utility model, as shown in Fig. 1,
The preferred supercentrifuge includes ontology 1 and lid 3, is equipped with centrifugal chamber 2 in ontology, lid and ontology are rotatably connected to beat
Centrifugal chamber 2 is opened and covered, centrifugation plate 4 is equipped in centrifugal chamber.Attached drawing 2 is the internal schematic of its ontology, shown in attached drawing 2, in ontology
Equipped with motor 6, the rotation axis being motor driven 5, it is rotated shaft-driven centrifugation plate, rotation axis is equipped with bearing 7, the rotation axis
Usually rigid structure, when in order to enable it has the effect of damping and absorbs irregular movement, in the utility model improvement
Scheme in, which includes input shaft 51 and output shaft 52, and input shaft is connected with motor, output shaft with centrifugation plate connect,
Spring 53 is equipped between input shaft and output shaft, spring 53 is preloaded by torsion, and input shaft is passed torque by preloading spring 53
Be delivered to output shaft, when input shaft is less than the preload force of spring to the torsion of output shaft, the preloading spring make input shaft and
Remained stationary between output shaft, when input shaft is greater than the preload force of spring to the torsion of output shaft, input shaft and output shaft it
Between relatively rotate.Therefore, when motor generates significant shock, input lever is driven to generate significant shock, the biggish vibration
Instantaneously make input lever to there is biggish torsion to transmit between output rod, when transmitting, output shaft can turn with respect to input shaft
It is dynamic, this vibration transmitting can be reduced, and then there is shock-proof effect to centrifugation plate.
Preloading for the spring can be by various ways, in a kind of preferred mode, and output shaft is entered axis limitation to mention
It is preloaded for torsion described in spring, and output shaft can only be rotated in one direction relative to output shaft.This kind is limited to
It is varied, such as can be equipped with fixed device on input shaft and output shaft surface, provide in a rotation direction input shaft and
The rigidity of output shaft, can also be by input shaft and output shaft internal structure to provide this limitation.In a preferred implementation
In mode, as illustrated in figures 4 and 7, to provide this limitation by internal structure, in this fashion, input shaft and output
Axis is connected by spring 53, and input shaft is equipped with hollow portion, and central part periphery is equipped with card chamber 501, and output shaft, which is equipped with, gos deep into hollow portion
Center-pole 521, center-pole, which is equipped with, is caught in the card division 522 of card chamber, and card division is caught in card chamber to provide the limitation.Such as Fig. 4
Shown, output shaft can not do the movement in direction 500 relative to input shaft, therefore, so that it may preloaded spring, extruding of the card division to card chamber
Power is the preload force of the spring, and when having multiple card divisions, such as two, the preload force of spring is the sum of multiple extruding forces.
It is driven in input shaft by motor, when doing the movement of direction 501, input shaft makes rotatory force by preloading spring
It is delivered on output shaft, output shaft is made to do the movement in direction 500, and be further driven to centrifugation plate.When the torsion that input shaft 51 exports
When power is less than the preload force of spring, spring will not further be applied load, and card division is limited by card chamber, in the institute of such as Fig. 3 and 4
The position shown, output shaft and input shaft will not relatively move.
When input shaft due to accelerating etc. suddenly, input shaft moment can be made to apply huge rotatory force to output shaft,
In the case, the spring of initial preload can not provide enough torsion, and spring can be by further clamp load, and output shaft is opposite
Input shaft rotation, card division is in the intracavitary movement of card, as shown in figure 5, only cracking, card division can return to initial position again.In this feelings
Under condition, the vibration of moment can not be delivered in output shaft by input shaft, with damping effect.
In the present embodiment, the preload force of spring can be adjusted by card division and the position of card chamber, the size of preload force
Can revolving speed etc. according to centrifuge, need higher revolving speed under normal conditions, preload force can be arranged larger.
In a preferred solution, card chamber is two, and card division is two, and two card chambers and card division respectively correspond, two
The cooperation of a card chamber will not generate excessive vibration so that the gravity of output shaft and input shaft is symmetrical in the rotation.
