FLOOR-TREATING MACHINE

摘要

A floor-treating machine comprises a frame (2) with actuating means (10), a housing (3), which is attached to the frame in such a manner that it can rotate about a substantially vertical axis and in which at least three heads (7), which can each rotate about a substantially vertical axis, are mounted, which heads are provided, on their bottom surface, with treating means and/or coupling means for treating means to be coupled to, a motor (22), the shaft (28) of which is concentric with respect to the vertical axis of the frame, which shaft is in driving interaction with the housing and the heads by means of respective transmissions. The transmission for driving the housing comprises an auxiliary shaft (23) which runs parallel to and at a distance from the centre axis of the frame, which auxiliary shaft is connected, via a first auxiliary transmission (25, 26, 27), to the motor shaft and is connected, via a second auxiliary transmission (5, 13, 18), to the housing.
