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.
