Abstract

A screw-nut screw transmission coupling 1 of the circulation-ball bearing type, in which the screw-nut 12 includes an inner sleeve 6 of which a first portion 7 is formed with a helical groove 8 for ball bearings 10, and another portion 15 forms an extension for connection of the screw-nut 12 to another member of a kinematic chain, which is a motor 14 in the embodiment described. The rotor windings 16 of the motor are directly mounted on the portion 15. <IMAGE>
