Machine for screeding floor surfaces
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.
1. A machine for screeding floor surfaces, comprising:
a drive motor;
a motor plate;
a planet disk configured to rotate relative to the motor plate;
a number of rotatably supported screeding disks distributed over the planet disk, the number of screeding disks being four or six, half the number of screeding disks having a direction of rotation coinciding with the planet disk and the remaining screeding disks having an opposing direction of rotation; and
first and second belt sheaves operatively connected to a respective one of the screeding disks having the same direction of rotation, a third belt sheave fixed to the motor plate, and a belt arranged between and in contact with the first, second, and third belt sheaves.
2. The machine of claim 1 , wherein the drive motor is fixedly connected to the motor plate.
3. The machine of claim 1 , wherein the drive motor drives at least a shaft belt sheave.
4. The machine of claim 3 , further comprising a second belt running over the shaft belt sheave, and operatively connected to at least the first and second belt sheaves.
5. The machine of claim 1 , further comprising a second drive motor for driving solely the planet disk.
6. The machine of claim 1 , wherein the screeding disks define one screeding plane.
7. The machine of claim 1 , further comprising deflection sheaves arranged between the belt sheaves.
8. The machine of claim 7 , further comprising a third belt that runs over the belt sheaves and the deflection sheaves.
