Anordning vid mobil maskin för slipning av golvytor

摘要

The invention relates to an arrangement in a mobile machine for screeding floor surfaces. This comprises a housing with a planet disk ( 3 ), which is rotatably supported in the bottom of the said housing and driven by a drive motor ( 1 ). The planet disk carries a number of rotatably supported screeding disks, distributed over the planet disk ( 3 ) and operatively connected to the drive motor ( 1 ). According to the invention the number of screeding disks is an even number up to a maximum of six. Viewed in the direction of rotation of the planet disk ( 3 ), half the number of screeding disks have a direction of rotation coinciding with the planet disk ( 3 ) and the remaining screeding disks an opposing direction of rotation.
