Abstract

Belt drive (10) with a drive shaft (18) rotatably driven by a drive motor (14), which carries a drive pulley (20), and an output shaft (38) which carries an output pulley (40), wherein the output pulley (40) is connected to the drive pulley (20) via a belt (44) and is rotatably driven, and the drive shaft (18) of the drive motor (14) and the output shaft (38) are arranged at a mutual radial distance (d) in a common housing (12), and a device for adjusting the tension of the belt (44) is provided, wherein the device for adjusting the tension of the belt (44) comprises a motor housing (16) of the drive motor (14), which is arranged radially displaceable and lockable in the housing (12) with respect to the axis of rotation (39) of the output shaft (38) and the output pulley (40).
