In an example embodiment, a floor sander comprises a motor having at least two selectable speeds, and a sanding adaptor driven to rotate about a rotational axis by the motor. The sanding adaptor includes a planetary disk that rotates about the rotational axis of the sanding adaptor. In addition, the sanding adaptor includes a plurality of sanding head units, each of which is coupled to the planetary disk for independent rotational movement. Each sanding head unit therefore rotates about its own rotational axis independently of any other sanding head unit or the planetary disk. An isolator is also provided, and is positioned generally between the planetary disk and the motor.

A grinding head unit mountable in a planetary disk of a surface grinding machine generally including a housing mountable on the planetary disk, a holder supported on the housing and a surface grinding member detachably connectable to the holder wherein the holder is provided with a recess and the holder is provided with a portion receivable within such recess.

Floor grinding machine and grinding head unit therefor

A surface grinding machine generally consisting of a drive means provided with an output shaft; a planetary disk mounted on the shaft; and at least two grinding head units mounted on the planetary disk, each including a housing mounted on the planetary disk, a shaft having a flange portion, journaled in the unit housing, resilient means interposed between the housing and the flange portion of the unit shaft and a disk provided with a grit surface disposed on an outer side of the flange portion of the unit shaft.

A gearbox arrangement couples an input shaft to an output shaft whereby the output shaft is driven by the input shaft in a constant rotational direction but at two different rotational speeds depending upon the particular direction of rotation of an input shaft for a given rotational speed of the input shaft. The input shaft has an input gear integral therewith and the output shaft has an output gear integral therewith. A first unidirectional clutch couples the input shaft with the output shaft such that rotation of the input shaft in a first input direction at a first input speed rotates the output shaft in a first output direction at a first output speed, but rotation of the input shaft in a second, opposite input direction causes the first unidirectional clutch to slip. An idler gear meshes with and is driven by the input gear. An intermediate shaft has a first intermediate gear integral therewith. The first intermediate gear is meshed with and driven by the idler gear. A second intermediate gear is meshed with the output gear. A second unidirectional clutch couples the second intermediate gear with the intermediate shaft such that rotation of the input shaft in the second input direction at a second input speed rotates the output shaft in the first output direction at a second output speed, but rotation of the input shaft in the first input direction causes the second unidirectional clutch to slip. A floor maintenance machine utilizes the gearbox arrangement.
