The invention relates to a system () for moving a support plate (), the support plate () being, in a so-called neutral position, substantially parallel to an XY plane defined by a so-called X direction and a so-called Y direction,saidthesystem comprising at least two control stages (EE) which are superimposed in a direction Z orthogonal tosaidtheX and Y directions, the two control stages (EE) being secured to each other, at least one ofsaidthecontrol stages (EE) comprising a control module (MM), the control module (MM) comprising only movement units designed so as to each generate a translational movement in an XY plane, respectively in different directions.

System for generating the movement of a support plate in six degrees of freedom

The invention relates to a system () for moving a support plate (), the support plate () being, in a so-called neutral position, substantially parallel to an XY plane defined by a so-called X direction and a so-called Y direction, said system comprising at least two control stages (E, E) which are superimposed in a direction Z orthogonal to said X and Y directions, the two control stages (E, E) being secured to each other, at least one of said control stages (E, E) comprising a control module (M, M), the control module (M, M) comprising only movement units designed so as to each generate a translational movement in an XY plane, respectively in different directions.

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.
