Abstract
An apparatus for vibration reduction in a linear actuator includes one or more sets of counterweights, one or more enclosures configured to receive one set of counterweights for each enclosure, and a driving shaft configured to mount the one or more sets of counterweights. The one or more sets of counterweights are disposed symmetrically with respect to a plane that extends perpendicularly and longitudinally through a longitudinal axis of the linear actuator. The driving shaft extends perpendicularly and transversely through the longitudinal axis and the plane. A portion counterweight of a given set of counterweights may rotate clockwise and another portion counterweight of the given set of counterweights may rotate counterclockwise.
