Installation for treating mass-produced parts, with secondary drive device

An installation for treating mass-produced parts, the installation comprising:

• a supporting structure with a supporting element;
• a basket carrier for at least two centrifuge baskets;
• and
• a main drive device attached to the supporting structure and having a main drive and a longitudinal shaft, wherein the longitudinal shaft is mounted rotatably about a main axis with respect to the supporting element and is drivable rotatably about the main axis by the main drive, wherein the basket carrier is held suspended on the longitudinal shaft and is connected to the longitudinal shaft in a rotationally fixed manner, and a secondary drive device with at least one motor and, for each centrifuge basket, a drivetrain for rotating the centrifuge basket about a basket axis radially distanced from the main axis,
• wherein the at least one motor of the secondary drive device is arranged on the basket carrier,
• wherein the drivetrain respectively comprises a reduction gear with a gear housing which is fixed to the basket carrier, an input shaft which is rotatably drivable by the at least one motor, and an output element coaxial with the basket axis, wherein a transmission ratio between an input speed of the input shaft and an output speed of the output element is greater than one.
