    摘要： The present disclosure relates to a grinding head (1) for a floor grinding machine (100) for grinding floor surfaces of stone or stone-like material. The grinding head comprises a lower casing member (3), comprising a lower support (31), an upper casing member (2), comprising an upper cover (21), a first belt pulley (611), arranged on an axle extending substantially parallel with an axis of rotation of the grinding head (1), and a second belt pulley (8), spaced from the first belt pulley (611) in a direction perpendicular to the axis of rotation of the grinding head (1), and partially overlapping the first belt pulley (611), its associated axle and/or its associated bearing, as seen in a plane parallel with the lower support (31). The second belt pulley (8) comprises an edge recess (81), which is sized and adapted such that when the edge recess (81) is arranged with its opening towards the axis of rotation of the first belt pulley (611), the first belt pulley (611), its associated axle and/or its associated bearing is free from said overlap.

    摘要： A rotatable disc head for a floor treatment device comprises a pair of coupling members which are pivotably connected to each other according to pivot axes which are transversely oriented with respect to each other. A rotation axis is defined which is transversely oriented with respect to said pivot axes. The coupling members are furthermore connected to each other by means of at least an elastically deformable connection element. One of the coupling members comprises fitting means for mounting said coupling member to the rotary drive of the floor treatment device and the other coupling member comprises carrier means onto which a floor treatment element, such as a grinding disc, can be mounted. The connection of the connection elements to one of the coupling members is an adjustable connection allowing displacements which are oriented transversely with respect to the rotation axis.
