ABSTRACT:
A linear actuator (10) comprises a slider tube (24), a mount (26) located upon the slider tube (24), slider brackets (28) through which the slider tube (24) slides, a screw rod (30) rotation of which results in translation of the slider tube (24) and the mount (26), a stop (32) and a lock nut that enable a translational setting to be set, and a buttress (36). The linear actuator (10) imparts precise translational motion to an object such as bearings (20) of a take-up pulley (18) of a conveyor (12) and is subject to forces of tension and compression in the direction of translational motion. The screw rod (30) has a first end (62) and a second end (64). Rotation of the screw rod (30) causes the first end (62) of the screw rod (30) to be inserted further within the slider tube (24) or withdrawn therefrom, depending upon the direction of rotation. The buttress (36) is located proximate the second end (64) and substantially redirects the forces of tension and compression to a side wall (16) upon which the linear actuator is fixedly mounted. The buttress (36) is of sufficient bracing so as to not deflect under the forces.
