摘要：
A linear actuator (10) comprising:
- a rotatory input shaft (13) driven by an electric motor having a helical threaded zone (15) in its external surface at its inner end:
- an output shaft (29) having a helical threaded zone (18) in its external surface at its inner end;
- a plurality of first helical roller gears (21,21',21") configured to engage with the rotatory input shaft (13) in its helical threaded zone (15) so that they rotate with respect to their axis (22,22',22") when the input shaft (13) rotates;
- a plurality of second helical roller gears (23,23',23") configured to engage with the first helical roller gears (21,21',21") and with the output shaft (29) in its helical threaded zone (18) so that the rotation of the first helical roller gears (21,21',21") is firstly transmitted to the second helical roller gears (23,23',23"), which rotate with respect to their axis (24,24',24"), and secondly converted in a linear movement of the output shaft (29).
