Description
Technical field
The utility model belongs to laboratory centrifuge, and in particular to a kind of flexible driving device for centrifugal machine of band protection.
Background technology
Core component of the device as centrifuge of centrifuge driving rotary head, from being simply directly driven to indirect drive
It is dynamic, from rigidity driving to soft drive, realize development of the centrifuge speed to high speed.The flexibility that conventional high rate centrifuge uses
Drive device mode, generally uneven beat is detected against motor, lacks the direct detection to flexible unbalanced shaft beat, lacked
, the problem of security is bad, reliability is not high be present in dynamic support during the weary beat to flexible shaft.
Utility model content
The purpose of this utility model is the centrifuge soft drive for providing the band protection that a kind of security is good, reliability is high
Device.
Realize that the technical scheme that the utility model purpose uses is as follows：
The flexible driving device for centrifugal machine of band provided by the utility model protection, including with the flexible shaft of motor connection, set
Stop collar, centrifuge engine control system on the motor, the stop collar are provided with into gap and are enclosed on the flexible shaft
On bearing and feedback component, the centrifuge engine control system electrically connected with the motor and feedback component.
Insulation sleeve is provided between the feedback component and stop collar.
The feedback component includes the conduction for being set on flexible shaft and being electrically connected with the centrifuge engine control system
Ring and the spring in circumferentially support conductive rings.
The beneficial effects of the utility model
1st, uneven beat detection is directly carried out to flexible shaft, it is simple, accurate, the accuracy of detection is drastically increased,
The security of centrifuge.
2nd, the bearing being located on stop collar during flexible shaft beat to forming dynamic support, when effectively protecting flexible shaft beat
It will not rub to fixed part and damage.
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings.

Embodiment
See Fig. 1, Fig. 2, the flexible driving device for centrifugal machine of band protection provided by the utility model, including motor 16, be located at
Flexible shaft 5 on motor 16, the stop collar 15 for being fixed on motor 16 and being set on flexible shaft 5, it is located on stop collar 15 and connects
The feedback component 14 of nearly flexible shaft 5, the insulation sleeve 13 being located between feedback component 14 and stop collar 15, limit is located at by back-up ring 3
In position set 15 and the bearing 4, the cone that is fixed on by screw 9 positioned at the upper end of stop collar 15 on flexible shaft 5 that are set on flexible shaft 5
Shape rotor base 6, the rotor base 6 are provided with interior swivel nut 7 and clamping screw 8, and rotor base 6 is by there is the small taper hole that " self-locking " acts on
12 are fitted close with flexible shaft 5；The feedback component 14 includes the conductive rings 2 being set on flexible shaft 5 and passed in circumferentially support
The spring 1 of lead ring 2；Stop collar 15 is screwed on the shell of motor 16, and the lower end of flexible shaft 5 is fixed on rotor main shaft
On, the gap of flexible shaft 5 and the inner ring hole of bearing 4 is 1 millimeter, the gap of conductive rings 2 and flexible shaft 5 0.1 millimeter to 1 millimeter it
Between, centrifuge engine control system one end electrical connection feedback component 14, other end electrical connection motor 16.
Operation principle：
The rotary head 10 of centrifuge coordinates provided with taper hole with rotor base 6, and is fixedly mounted on rotor base 6 by clamping screw 8
On interior swivel nut 7 on.When centrifuge works, the motor 16 in flexible drive device drives installation by flexible shaft 5, rotor base 6
There is test tube（Cup）The high-speed rotation of rotary head 10, due to the insulation feature of insulation sleeve 13, feedback component 14 and flexible drive device
Other parts are not turned on.The rotary head 10 of rotation has gyroscopic effect at a high speed, because gyro has two features：Precession and dead axle
Property；During centrifuge equilbrium running, due to the gyroscopic inertia of gyroscopic effect beat or beat amplitude very little do not occur for flexible shaft 5, flexibility
Conductive rings 2 in axle 5 and feedback component 14 remain the gap between 0.1 millimeter to 1 millimeter.If test tube in rotary head 10（Cup）
Liquid feeding is uneven or abnormal rupture, rotary head 10 can produce precession, and beat occurs for flexible shaft 5, when flexible shaft 5 touches conductive rings 2,
Feedback component 14 and the other parts of flexible drive device can then turn on, and centrifuge engine control system receives Continuity signal just
Instruction stop, uneven automatic shutdown protection is provided for centrifuge.When flexible shaft 5 touches the inner ring of bearing 4, bearing 4 is with flexibility
Axle 5 is rotated together, and dynamic support is formed to flexible shaft 5, effectively protect will not be rubbed during 5 beat of flexible shaft to fixed part and
Damage.
