Kinematic system with motion control device
Abstract:
A kinematic system is provided that includes an outer cylinder, a mid-cylinder and an inner cylinder. The mid-cylinder is within the outer cylinder, and mated with the outer cylinder at a mid-outer threaded interface configured to transform axial translation of the outer cylinder into rotational motion of the mid cylinder along an axis. The inner cylinder is within the mid-cylinder, and mated with the mid-cylinder at a mid-inner threaded interface configured to transform the rotational movement of the mid-cylinder into axial translation of the inner cylinder along the axis. A first one of the mid-outer threaded interface and the mid-inner threaded interface includes a thread configured with a first thread portion and a second thread portion. The first thread portion is disposed at a first angle relative to the axis. The second thread portion is disposed at a second angle relative to the axis that is different from the first angle.
