Abstract
A driving device for driving in rotation a toothed wheel, in particular a turntable, has a worm intended to mesh with the toothed wheel, a motor to drive the worm in rotation, a flexible sleeve that partially surrounds the worm in such a way as to form an assembly described as a worm/sleeve assembly, and a pre-stressing unit. The motor is arranged in a structure that is fitted pivotably relative to the worm/sleeve assembly, and the driving device also has a force transfer unit connecting the motor to the sleeve at a second extremity of the worm.
