  • Patent number: 5093610
    Abstract: An apparatus for measurement of absolute position of a movable machine member is provided. The machine member is moved by a motor and reduction device producing rotation of the machine member in proportion to relative rotation of the motor rotor and motor stator. Two angular position measuring devices provide output signals representing relative positions related to the machine member position and differentiated one from another.

  • Patent number: 5028153
    Abstract: A bearing block for anchoring a self-contained bearing for a moving part of a robotic manipulator to such robotic manipulator is provided, wherein the self-contained bearing has a known outside diameter. In particular, the bearing block comprises a body portion having attachment means for attaching the bearing block to the robotic manipulator, with such body portion being split into a base piece and a clamp piece along a dividing axis. A bearing race or bore is formed through the body portion and centered therewithin on the dividing axis. The bore is formed after the body portion has been split along the dividing axis, and has an effective diameter slightly undersized relative the outside diameter of the self-contained bearing to be held therewithin.

  • Patent number: 4827786
    Abstract: There is provided a backlash control rotation gear assembly for robotic applications, with such assembly comprising an input device to provide rotational force of a predetermined maximum torque. The system further includes a first drive gear which is connected to the rotational input device and a second drive gear which is connected to the first drive gear by an elastic torsion spring preloaded with a predetermined spring torque force. An output driven gear is connected to a moveable robotic part to be rotated, with such driven gear being connected to the first and second drive gears, wherein the first drive gear is driven by the rotational input device and the second drive gear is driven indirectly by the input device through the preloaded elastic torsion spring.

  • Patent number: 4787260
    Abstract: There is provided a self-aligning ballscrew assembly for a manipulator device for reciprocating an extension element along a linear extension axis, with the self-aligning ballscrew assembly including a ballscrew having a longitudinal axis. A ballscrew bearing block is provided having a ballscrew nut mounted on the ballscrew for translating an extension element of the manipulator device along a linear extension axis in response to relative rotation between the ballscrew and the ballscrew nut, and a drive motor selectively provides relative rotation between the ballscrew and the ballscrew nut.

  • Patent number: 4764033
    Abstract: There is provided a rotator bearing shock and vibration dampener for the rotator bearing of a robotic manipulator, with such shock dampener including a stationary robot base and a rotary turntable, and a large rotary turntable bearing having its inner race bolted to the stationary base and its outer race bolted to the rotary turntable. An oil damp well space having a relatively thin, predetermined depth squared relative its surface area is formed in the base below the outer race and in the turntable above the inner race. A predetermined volume of damping oil is located adjacent the turntable bearing in the base and fills the oil damp well space, whereby the damping oil normally resides in the well space to provide an oil film therewithin.

  • Patent number: 4642212
    Abstract: A robotic base compartment has an interior locating surface. A plurality of pins extend squarely from the locating surface. The pins are located by pre-assembly machining and the extending pin surfaces are coated with a release agent. A robotic component plate, such as a gear-carrying plate, is assembled in the base compartment, with clearance slots surrounding the locating pins. After adjustably positioning the gear elements with one another by shifting the component plate, the slots are filled, for at least a portion, with a pourable hardenable material such as epoxy which is then allowed to harden. The components may thereafter be disassembled and reassembled without the loss of precision location. The assembly method obviates the need for manual drilling and reaming of pin holes at assembly and the attendant chip contamination that results therefrom.

  • Patent number: 4606667
    Abstract: A stationary robotic base carries a movable robotic platform and supports a pair of vertical striker plates spaced apart by a central, elastomeric block. The striker plates are confined within a compartment of the stationary base, and extend upward into a pathway defined by a lug depending from the moving platform. The lug contacts the top portion of a given striker plate and, as the plate is struck, it tends to pivot about its bottom edge toward the other plate, compressing the elastomeric block, while the other plate is held from moving away from the block. The assembly is bidirectional, with each striker plate being yieldable toward the other as it is encountered by the moving lug.
