The technology disclosed herein can include a motor unit having a motor with a motor gear to rotate a drive shaft and a drive gear. A manual input shaft can also be configured to transmit rotation to the drive shaft. The motor can have a central axis that forms an angle of less than 90 degrees with a plane substantially defined by an outer surface of a gear box coupled to the motor. A mounting bracket is configured to allow mechanical communication between the motor unit and an internal ring gear. The internal ring gear can be mounted to a vehicle and a turret can be pivotably disposed within the internal ring gear. A motor unit is mounted on the turret and a drive gear is rotatably mounted on the motor unit and in direct engagement with the internal ring gear.

A torque transmission and sealing assembly includes a ring gear having a first axial end, a second axial end opposite the first axial end, an inner surface including a plurality of teeth and an axial-facing surface at the first axial end, a barrel portion joined to the second axial end of the ring gear, and a plurality of annular, axial extending fingers integrally formed with the ring gear and extending from the axial-facing surface.

The arm structure of a robot includes a first motor and a second motor attached to an arm member, a first bearing attached to the arm member, an arm member supported on the arm member by the first bearing, a first gear rotating together with the first bearing, a first motor transmission gear transmitting rotation force of the first motor to the first gear, a second bearing attached to the arm member and having a center axis perpendicular to a center axis of the first bearing, a rotary member supported on the arm member by the second bearing and rotatable relative to the arm member, a second gear attached to the rotary member, and a second motor transmission gear transmitting rotation force of the second motor to the second gear to make the rotary member rotate.

Systems and methods in accordance with embodiments of the invention implement bulk metallic glass-based macroscale gears. In one embodiment, a method of fabricating a bulk metallic glass-based macroscale gear, where at least either the thickness of the gear is greater than 3 mm or the diameter of the gear is greater than 9 mm, includes: obtaining design parameters of the gear to be formed; selecting a bulk metallic glass from which the gear will be formed based on the obtained design parameters, where the selected bulk metallic glass is characterized by a resistance to standard modes of wear and a resistance to brittle fracture such that a gear can be formed from the selected bulk metallic glass that accords with the obtained design parameters; and fabricating the gear from the selected bulk metallic glass that accords with the obtained design parameters.

Apparatus and associated methods relate to a motor-less cartridge ring gear engagement module (CRGEM) for a turret-rotating system that includes a main drive gear configured to rotate in a rotation plane, a manual input shaft that extends substantially orthogonal relative to the rotation plane, and a drive shaft that extends substantially orthogonal relative to the rotation plane, where the drive shaft and the manual input shaft extend substantially parallel to one another. In an illustrative example, both the main drive gear and a hand crank may be located on a top surface of the CRGEM. In some embodiments, a manual drive cap may be hingedly coupled to the gearbox and configured to rotate in a vertical plane that is substantially orthogonal to the rotation plane. At least some examples may provide for a hand-operated, manual traverse unit that advantageously does not require electrical power to operate.
