Abstract
Apparatus for moving tubes (10) which are displaceable upon operation of an actuator (40) inside fixed guides (20) integral with the tower (1a) of submarines (1) and the like, said actuator (40) consisting of at least one pair of linear motors (41).
Claims18
An apparatus for moving a tube which is displaceable with respect to a tower of a submarine, comprising:
- an actuator,
- a fixed guide positioned within the tower for axially movably supporting the tube, the actuator operably connected between the fixed guide and the tube for axially moving the tube, the actuator including a pair of linear electric motors, each of which has a fixed component and a movable component arranged along a single pair of opposing sides of the fixed guide and the tube, respectively;
- wherein the movable component of each linear electric motor comprises windings integral with the movable tube and the fixed component of each linear electric motor is integral with the fixed guide and forms a structural wall of the fixed guide.
An apparatus for moving a tube which is displaceable with respect to a tower of a submarine, comprising:
- an actuator, coupled to the tube,
- at least one fixed guide positioned within the tower of the submarine for axially movably supporting the tube,
- wherein said actuator is operably connected between the fixed guide and the tube for axially moving the tube and includes at least one pair of linear electric motors, each linear motor having a fixed and movable component arranged along a single pair of opposite sides of the fixed guide and the tube, respectively;
- wherein the movable component of each linear electric motor comprises windings integral with the movable tube and the fixed component of each linear electric motor is integral with the fixed guide and forms a structural wall of the fixed guide.
1 more element
An apparatus for moving a tube which is displaceable with respect to a tower of a submarine, comprising:
- a fixed guide positioned with the tower,
- an actuator positioned inside the fixed guide and including a pair of linear motors,
- wherein the linear motors comprise windings arranged asymmetrically along a longitudinal direction of movement of the tube to produce a torque from forces of attraction between fixed components and movable components of the linear motors.
