Abstract
The actuator comprises a tubular nut () coupled by means of an external thread () to the casing () of the actuator. The nut has an internal thread () opposite the external thread, for engaging a threaded rod () which is prevented from rotating with respect to the casing. A geared motor () rotates a pinion () which, through two straight spur gears (), causes the nut () to bring about a screwing movement along a longitudinal axis (x), while the rod () translates rapidly in telescopic manner with respect to the casing (). The spur gears have a pinion portion of greater diameter () meshing with the pinion (), and a splined shaft portion () meshing with a pinion member () integral with the nut ().
