Abstract

An unmanned turret having a turret ring gear and first and second electrical force-producing devices with the unmanned turret being rotatably mounted to a vehicle chassis, the turret drive mechanism including at least one ring gear independent of the turret ring gear, at least one manually-operable input component rotatably coupled to the at least one ring gear, the at least one input component accessible within the vehicle chassis, and at least one output component mechanically coupled to at least one of the first and second electrical force-producing devices of the unmanned turret to cause rotation of the at least one of the first and second electrical force-producing device. Another turret drive mechanism and an unmanned turret are also disclosed.

Claims

An unmanned turret having an unmanned turret drive system comprising a turret ring gear and first and second electrical force-producing devices with the unmanned turret being rotatably mounted to a vehicle chassis wherein the unmanned turret drive system being powered by electrical power and controlled by a control signal, the unmanned turret comprising, a remote turret drive mechanism, the remote turret drive mechanism comprising:

a first ring gear independent of the turret ring gear;

a second ring gear independent of the turret ring gear and arranged in a concentric relationship with the first ring gear;

a first manually-operable input component rotatably coupled to the first ring gear, the first input component accessible within the vehicle chassis;

a second manually-operable input component rotatably coupled to the second ring gear, the second input component accessible within the vehicle chassis;

a first output component mechanically coupled to the first electrical force-producing device of the unmanned turret drive system to cause rotation of the first electrical force-producing device; and

a second output component mechanically coupled to the second electrical force-producing device of the unmanned turret drive system to cause rotation of the second electrical force-producing device wherein the remote turret drive mechanism is interfaced with the unmanned turret drive system to manually control the unmanned turret drive system when at least one of the electrical power and the control signal is lost.

2. The unmanned turret of claim 1, wherein the first ring gear is an azimuth ring gear and the first electrical force-producing device by being rotated is configured to rotate the unmanned turret azimuthally.

3. The unmanned turret of claim 2, further comprising a weapon mount and the second electrical force-producing device, by being rotated, is configured to elevate and depress the weapon mount.

4. The unmanned turret of claim 1, further comprising a surface and an interface housing having a first housing section configured to be mounted to the surface;

and a second housing section, the second housing section configured to be mounted to the vehicle chassis such that the first housing section is rotatable with respect to the second housing section and at least one of the first manually-operable input component and the second manually-operable input component is accessible within the vehicle chassis.

5. The unmanned turret of claim 4,

wherein the interface housing is integrated with a slip ring housing.

6. The unmanned turret of claim 1, wherein each of the first output component and the second output component further comprises a gear assembly comprising a first gear rotatably coupled to a second gear.

7. The unmanned turret of claim 6, wherein the first gear comprises a vertically-oriented first miter gear and the second gear comprising a horizontally-oriented second miter gear.

8. The unmanned turret of claim 1, wherein each of the first input component and the second input component comprises an input drive shaft accessible within the vehicle chassis to attach a manually manipulated element for rotating the input drive shaft.

9. A remote turret drive mechanism for an unmanned turret powered by electrical power and controlled by a control signal, the remote turret drive mechanism comprising:
