Abstract
Official abstract text for this publication.
A linear actuator including the gap compensating unit with the joints and the elastic units to provide the elasticity thereby compensating the offset during the linear motion and maintaining the stability and linearity.
First claim
Opening claim text (preview).
What is claimed is: 1. A linear actuator, comprising: a case, comprising a body and a space; an actuating unit, held in the space; and a gap compensating unit, reciprocating on the actuating unit and comprising a base, a plurality of apertures, a plurality of joints and a plurality of elastic units, wherein the apertures are positioned on two opposite sides of the base, the joints are respectively received in the apertures, and the elastic units are respectively received in the apertures to be disposed against the joints and an inner wall of the body; wherein the gap compensating unit comprises two covers respectively disposed on the two opposite sides of the base, each of the cover comprises a plurality of openings, and the base comprises a plurality of holes corresponding to the openings to form the apertures. 2. The linear actuator as claimed in claim 1 , wherein the diameter of the opening is less than the diameter of the hole. 3. The linear actuator as claimed in claim 1 , wherein the gap compensating unit comprises a plurality of bolts, each of the cover comprises a plurality of punctures, and the base comprises a plurality of screw holes whereby the bolts are fastened within the punctures and the screw holes. 4. The linear actuator as claimed in claim 1 , wherein the gap compensating unit comprises an axial hole positioned on the base to hold the actuating unit. 5. The linear actuator as claimed in claim 1 , wherein the joints are in the form of a ball.
