Patent ID: 7140957

Claim:
An arrangement in a mobile machine for screeding floor surfaces comprising: a housing with a planet disk rotatably supported in the bottom of the housing and driven by a drive motor, and which carries an even number of up to six but not less than four screeding disks, operatively connected to the drive motor and defining one screeding plane, wherein the operative connection comprises: belt sheaves, wherein a belt sheave is associated with each of the screeding disks, deflection sheaves arranged between the belt sheaves, a first belt arranged such that the first belt bears against a part of the circumferences of the belt sheaves and against a part of the circumferences of the deflection sheaves, wherein the first belt alternates from belt sheave to belt sheave and lies alternately closest to the center of the planet disk and furthest away from the center of the planet disk and wherein the first belt lies furthest from the center when bearing against the deflection sheaves, and a second belt running between a belt sheave arranged on the shaft of the motor and one of the belt sheaves belonging to the screeding disks.
