Abstract
A drive roller unit for driving articles on a conveyor track includes a drive roller which can be driven in rotation by an electric motor by way of a planetary transmission and a transmission arrangement including a drive gear. The drive roller is mounted rotatably on a guide body by means of which it is movable with respect to a base of the unit between a lower rest position and an upper drive position in which it is in engagement with the underside of the article to be driven. The guide body is mounted rotatably with respect to the electric motor. A first motor element such as the stator of the electric motor is rigidly and non-rotatably connected to the base while a second motor element is coupled to the sun wheel of the planetary transmission. The crown wheel of the planetary transmission drives the guide body and the other output of the planetary transmission drives the drive gear for driving the drive roller in rotation.
