Abstract
A motor is disposed above the protective covering or chassis of a movable surface treatment device. Via its vertically arranged power take-off shaft, the motor drives the horizontally extending rotor shafts, on which respectively one rotor cage is disposed on both sides of a gear housing. The rotor shafts are driven in opposite directions, so that one drum mills in the same direction and the other drum mills with opposite horizontal rotary movement. The gear housing is driven in a stepped-down manner via a two-stage transmission by a power take-off pulley disposed on the power take-off shaft. The rotor cages make two superimposed rotary movements. Thus, the treated surface no longer has a grooved appearance, the surface is treated more evenly and better, and finally, no self-driving force acts on the movable surface treatment device. Work safety is thus increased in addition to work quality. One rotor cage is driven in the same direction, the other in the opposite direction with respect to the horizontal rotation, by which the work output is increased and the appearance of shadows is removed.
