3-POINT LINK VECTOR THRUSTER AND MANUFACTURING METHOD

摘要

PURPOSE: A 3-point link vector thruster and a manufacturing method thereof are provided to use in an underwater robot such as a small autonomous underwater vehicle. CONSTITUTION: A 3-point link vector thruster comprises a first ball joint(11), a second ball joint(12), a first linear actuator(21), a second linear actuator(22), and a second axial link(30). The first and second ball joints are attached at the top of a propulsion motor housing(2). One end of the first and second linear actuators is connected to the first and second ball joints, respectively. The other end of the first and second actuators is connected to a hull structure. One end of the second axial link is attached at the bottom of the propulsion motor housing and the other end thereof is fixed in the hull structure.
