Abstract:
An orbiter floor machine for treating floors, the floor machine having a top-hat-like housing with a handle extending upwardly toward a user. The floor machine includes a motor having a rotatable drive shaft extending therefrom, the drive shaft having a shaft axis. An annular flywheel has an axial opening that fixedly receives the drive shaft so that rotation of the drive shaft causes rotation of the flywheel. A bearing assembly has an eccentric aperture through which the drive shaft extends such that the bearing assembly has an axis that is radially spaced from the shaft axis. The bearing assembly is secured to the flywheel such that the rotation of the flywheel causing the bearing assembly to orbitally rotate such that the bearing axis orbits about the drive shaft axis. A counterbalance weight is secured to an outside perimeter of the flywheel in a position opposite to the bearing assembly axis with respect to the shaft axis. The forces caused by the orbiting motion of the weight acts to counterbalance the forces caused by the orbiting motion of the bearing assembly.
