    摘要: Provided is a method of driving a joint device suitably used for a robot joint with improved back drivability. A first motor and a second motor are fixedly connected to a first link. An output shaft of the first motor is coupled to an internal gear of a differential speed reducer. An output shaft of the second motor is coupled to an external gear of the differential speed reducer. A second link is coupled to the internal gear of the differential speed reducer. When the first link and the second link are relatively stopped to keep a joint angle fixed, both of the first motor and the second motor are rotated with a rotational speed larger than zero, and the rotational speed of the first motor and that of the second motor are differentiated to stop the second link.

    摘要: An improved robotic arm system for servicing the tubesheet located within the channel head of a nuclear steam generator is provided. The system includes a robotic arm whose shoulder and elbow joints are rotatable only in the plane parallel to the tubesheet in order to eliminate the imposition of cantileverly-induced torques on the electric motors driving these joints, as well as to minimize the possibility of mechanical interference between the arm and the walls of the channel head. Each of the motorized joint assemblies of the arm includes resolvers connected not only to the output of the drive train that moves the joint, but also to the drive shaft of the electric motor that drives the drive train, wherein the feedback signal generated by the resolver connected to the drive shaft of the electric motor is the primary signal used to modulate the amount of electric power conducted to the motor of the joint. Such a configuration advantageously results in smoother robotic arm movement. Finally, the control circuit assembly of the robotic arm system includes a control processing unit (CPU) which is capable of simultaneously driving not only the joint assemblies of the robotic arm, but also any computer-operated mechanisms associated with a variety of end effectors which the arm is capable of delivering. The CPU, power supply and other components of the control circuit assembly are installable in the containment area surrounding the steam generator in order to eliminate the number of cable penetrations through the containment walls that are necessary to operate the system.

    摘要: A robot joint has a support carrying a rotary robot arm. An electric drive motor is mounted on the support and its drive shaft is coupled to the robot arm by harmonic drive-type reduction gears. The reduction gears include an elastically deformable, externally toothed ring whose elliptical shape is rotated by the drive shaft. The externally toothed ring itself is stationary and is firmly connected to the support by a flexible sleeve provided at its free end with a rigid mounting flange. The annular mounting face of the flange and the opposite mounting face on the support is each provided with radial teeth, preferably in the form of Hirth-type gears, which guarantee an accurate centering of the sleeve and safeguard the same against turning. Preferably, the flange is fastened to the end face of a steel bushing which is pressed into a bore in the support and secured against turning by knurled serrations. The robot arm is mounted for rotation in a pretensioned cross-roller bearing which provides a compact and bend resistant connection to the support.
