| 摘要 |
<p>The invention relates to a multiaxial linear actuating mechanism used in the structure of industrial robots. According to the invention, the mechanism comprises a motor (A) driving a transmission system with linear coaxial motion consisting of a non-reversible roller screw mechanism (B), the rotating screw (1) producing the displacement of a nut (2) integral with a tubular rod (3), which forms a first linear motion axis (I), while the externally threaded rod (3) forms another ball screw mechanism (C) whose also threaded tubular nut (4) wherein it is fixed forms another reversible ball screw mechanism (D) resting on a radial-axial bearing (E) allowing the displacement of a nut (6) fastened in a tubular rod (7), forming a second motion axis (II) which is rotation-free guided inside a cylindrical body (8).</p> |
