Abstract (en)
[origin: WO9730791A1] A decanter centrifuge assembly comprises a bowl (12), a screw conveyor (14) disposed inside the bowl for rotation at a speed different from an angular velocity of the bowl, and a harmonic drive unit (35) including a circular spline (16) drivingly connected to the conveyor. The harmonic drive unit further includes a flexible spline (26) drivingly connected to the bowl and a wave generator (34) disposed in contact with the flexible spline for distorting the flexible spline and enabling a driving of the flexible spline at a rate of rotation incrementally differing from a rate of rotation of the circular spline. The flexible spline has teeth partially meshing with teeth on the circular spline.
