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.
Arrangement in a mobile machine for screeding floor surfaces comprising 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), and which carries an even number of up to six but not less than four screeding disks, operatively connected to the drive motor (1) and defining one screeding plane, characterised in that the operative connection comprises, on the one hand, belt sheaves (4b 1-4b4) belonging to the screeding disks, over which sheaves and over deflection sheaves (5) arranged between the belt sheaves a belt (6) runs in such a way that the belt (6) bears against a part of the circumference of the belt sheaves, which alternating from belt sheave to belt sheave lies alternately closest to the centre of the planet disk (3) and furthest away from the said centre, and on the other a belt (7), which runs between a belt sheave 1a arranged on the shaft of the motor (1) and one of the belt sheaves (4b 1-4b4) belonging to the screeding disks.
Arrangement in a mobile machine for screeding floor surfaces comprising a housing with a planet disk (3), which is rotatably supported in the bottom of the said housing and which carries a number of rotatably supported screeding disks, distributed over said planet disk and operatively connected to a drive motor (1), and defining one screeding plane, characterised in that the planet disk (3) is operatively connected to a second drive motor, intended solely for driving the planet disk (3), and that the number of screeding disks constitutes an even number up to a maximum of six, and that, 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.
