Abstract

The assembly has a brush plugged on to a mounting with a drive shaft and the rotating brush in a vertical section though the axis of the drive shaft (8) overlapping a fixed baseplate on the inside. On the inside on the rotating brush part is a stepped recess which also overlaps the fixed part. The fixed part is formed as a projection of a gearbox (15) which incorporates the drive shaft, with the projection surrounding the inside end of the brush. The inside brush end is freely floating in the projection. An intermediate space between the gearbox and a cylindrical body covering it increases in size in outwards direction.
