Centrifuge Planetary Differential

Compoments

The centrifuge differential is composed of a two-pole planetary gear system, the first stage is a planetary mechanism, the second stage is a differential mechanism, and the tooth shape is involute. Both the first and second stages have three planetary gears. The first-stage input shaft (first-stage sun gear) is connected with the torque protection device by the rocker arm, the first-stage output shaft and the second-stage input shaft (second-stage sun gear) are connected as a whole by the short-tooth involute spline (we call this component the small three-star disc cover), and the second-stage output shaft (large three-star disc cover) is connected with the inner rotor through the spline shaft. The first and second stage inner gear rings and the differential shell are connected as a whole through the short tooth involute spline, and the differential shell is connected with the drum through the coupling plate.

How it works

When the centrifuge is working, the bowl drives the differential housing (i.e., the first and second inner ring gears) to rotate synchronously. Because the primary input shaft is fixed by a moment protection device, the relative rotation between the primary input shaft and the primary inner ring gear is formed, and this rotation is transmitted to the secondary input shaft (i.e., the planetary mechanism) by a certain rotation of the three asteroid gears meshed with the two. The relative rotation between the second-stage input shaft and the second-stage inner gear ring drives the three large planetary gears of the second-stage to transmit the relative rotation to the second-stage output shaft (i.e., the differential mechanism) according to a certain rotation.
