Abstract (en)
[origin: WO2019143278A1] A floor grinding machine comprising a supporting frame, a grinding unit attached to the supporting frame, and a drive unit connected to the grinding unit. The grinding unit comprises an upper housing, a lower housing rotatably arranged in relation to the upper housing, and a planetary drive system connected to the drive unit, where the upper housing comprises a top plate and a first side wall projecting downwards from the top plate in an axial direction. The lower housing comprises a bottom plate and a second side wall, where one or more grinding disks adapted for holding a tool are rotatably attached to the bottom plate, where the planetary drive system is arranged to rotate the lower housing and the one or more grinding disks respectively. The first side wall is coaxially arranged in relation to the second side wall, and the first side wall is in the axial direction at least partly overlapping the second side wall. A gap is formed in a radial direction between the first side wall and the second side wall, and a sealing element is arranged in the gap.
