The bigger prototype size of upward analog, thus there is irreplaceable technical advantage, drum centrifuge is in geotechnical engineering, seashore
The fields such as engineering and environmental geotechnical using more and more extensive.Drum centrifuge has inside and outside two independent concentric rotations
Shaft, wherein outer shaft is hollow shaft, and band movable model slot rotates, and inner shaft is mounted on inside outer shaft, drives actuator platform (fitting machine
Tool hand) rotation.
Only two units domestic at present have drum centrifuge, and are external development and production, Dalian University of Science & Engineering in 2009
University introduces First drum centrifuge from Broadbent company, Britain.By data consultation, the drum-type that foreign countries develop at present
Centrifuge has following feature: 1, drum centrifuge is vertical installation, has inside and outside two Concentric rotation axis；2, main drive
Dynamic system mostly uses pulley drive system；3, bearing arrangement mostly uses combination (such as cylinder of variety classes rolling bearing
Roller bearing and angular contact ball bearing combination)；4, inside and outside axis synchronously control mostly uses mechanical mode to realize inside and outside rotation axis
Combination with separate.
Drum centrifuge is different from arm-type centrifuge, it has inside and outside two independent Concentric rotation axis, outer shaft band dynamic model
Type groove rotation, inner shaft drive the rotation of actuator platform, and inside and outside axis can be rotated either synchronously or asynchronously.
Drum centrifuge belongs to rotating machinery, and according to its design feature and use condition, rotatable parts mostly use grease lubrication

The combination of bearing, drum centrifuge smaller for structure size, light load, it is sufficient to meet requirement, and for
The centrifuge that structure size is big, load is heavy, split bearing are easy fever in centrifuge high revolving speed operation for a long time.
Most of traditional drum centrifuge bottoms are fitted with clutch, to realize the combination of inside and outside rotation axis and divide
From thus outer shaft synchronous rotation or asynchronous rotary in controlling, it is ensured that the actuator platform that inner shaft drives can be at any time according to test need
Stop or re-synchronization rotates.It is this to realize connection in the high revolving speed operation of centrifuge by way of mechanical connection or divide
From being easy to produce biggish vibration.
The main drive system of traditional drum centrifuge (driving model slot) be essentially all using pulley drive system,
It is lower that drive characteristic causes transmission efficiency to compare, and belt under longtime running it is possible that loose or aging, thus shadow
Ring the stability and control precision of centrifuge speed.
We has developed a kind of geotechnological drum centrifuge device in order to solve problem above.
