摘要： A plural output differential drive system provides plural outputs that are differentially related to each other. Three or more output shafts are driven from a single input shaft, each output shaft being differentially linked with the other output shafts. The entire differential drive arrangement is contained within a single housing. The output shafts of the plural output differential will transfer power in applications wherein equal distribution of torque is required at three or more outputs. The input shaft may be arranged to be coaxial with the output shafts, or may be at any other angle, including orthogonal thereto. Typical applications include powering three or more live axles on vehicles, providing rotary power for developing equal torques for simultaneously tightening multiple bolts, and generating equal forces on the gripper fingers of robotic hands. In addition, the outputs can be applied to leveling devices where three or more legs must apply equal pressures on a surface. Differential action is made available to each of the tandem wheels of a truck vehicle, in one embodiment of the invention.

摘要： A plural output differential drive system provides plural outputs that are differentially related to each other. Four or more output shafts are driven from a single input shaft, each output shaft being differentially linked with the other output shafts. The entire differential drive arrangement may be expanded to any number of outputs, and is contained within a single housing. The output shafts of the plural output differential will transfer power in applications wherein a predetermined distribution of torque is required at four or more outputs, irrespective of their speeds. All the outputs are coupled as a series of all epicyclic differentiating mechanisms, or a series of epicyclic and bevel differentiating mechanisms. N outputs are achieved by introducing multiple epicyclic gear mechanisms. The input shaft may be arranged to be coaxial with the output shafts, or may be at any other angle, including orthogonal thereto. Typical applications include powering four or more live axles on vehicles, providing rotary power for developing equal or predeterminably proportional torques for simultaneously tightening multiple bolts, and generating equal forces on the gripper fingers of robotic hands. In addition, the outputs can be applied to leveling devices where four or more legs must apply equal pressures on a surface.

The modular design, includes a revolving tool cartridge having a plurality of tool holders, a meshing gear for engaging a tool holder with the spindle of the machine tool, and an adapter block for positioning the revolving tool cartridge on any standard machine-tool spindle head. The adapter block allows the automatic tool changer to be easily coupled to a wide variety of commercial machine-tool spindles, making the invention a truly reconfigurable and portable tool changer. The revolving tool cartridge incorporates a novel three-dimensional cam structure mechanism, which allows tool indexing to be achieved by means of only one actuator.

摘要： A variable camber airfoil has a leading portion and a trailing portion that is pivotally coupled to the trailing portion. A flexible skin substantially encloses the leading portion and the trailing portion and generally defines an airfoil profile. The skin is fixedly coupled to the trailing portion and is slidably coupled to the leading portion. Upon movement of the tail portion, the skin changes position with respect to the leading portion, and the internal structure of the wing changes the profile of the wing. The internal support structure of the wing supports a pivot bar that extends from the leading portion to the trailing portion. The pivot bar is pivotally connected to the support structure. One end of the pivot bar is coupled to the trailing portion, and the other end of the pivot bar is coupled to a movement linkage. The operator controls are ultimately coupled to the pivot bar. A plurality of support arms are coupled between the skin and the support structure. The support arms position the skin with respect to the support structure. When increased lift is desired, the tail pivots downward and the skin slides about the nose so that the upper portion of the skin extends further from support structure and lower portion of the skin is brought closer to support structure. The opposite is true for a reduction in lift.

摘要： An iris arrangement has first and second annular carrier elements annular elements coaxially arranged and circumferentially interlocked with one another so as to be independently rotatable. A plurality of iris elements each have a first compliant beam element coupled at a first end thereof to the iris element and at a second end thereof to the first annular carrier element, and a second compliant beam element coupled at a first end thereof to the associated iris element and at a second end thereof to the second annular carrier element. Rotatory motion of the carrier elements relative to each other results in substantially radial displacement of each of the iris elements. The plurality of iris elements communicate with one another when disposed in a radially innermost position. A web covers a region between the plurality of iris elements and the circumference of the first and second annular elements.

摘要： In accordance with the teachings of the present invention, a machine tool assembly is easily reconfigurable to perform single or multiple machining processes on a workpiece so that this machine has exactly the functionality required to perform a given set of machining tasks. The invention allows rapid changes in the machine structure and rapid conversion of the machine by relocating its basic building blocks. The assembly secures a raw workpiece to a table and includes support units that carry at least one single-axis spindle unit. The spindle units are easily attached to one of the support units and are easily movable thereon to perform machining processes from various positions and orientations relative the workpiece. A cutting tool, or other machining tool, is secured to each spindle, which is computer controlled to rotate the tool and stroke it linearly along its axis of rotation. The support units are reconfigurable and can be easily relocated to different positions and orientations about the workpiece.

摘要： A closed loop multi-link robotic apparatus is actuated to produce two-dimensional motion with respect to a base member. The base member is coupled to an actuator which, in a practical embodiment of the invention, moves the base member along a part which is rectilinearly orthogonal with the respect to the two-dimensional motion. A correlator, which may be an electronic system, controls the actuator to produce a predetermined composite three-dimensional motion which can be adapted to performed industrial automation tasks. Adjustability of the system is achieved by providing a mechanism for adjusting the length of one or more of the links. Additionally, other elements may be varied, such as an angular relationship between various ones of the rigid links or the angular relationship between an end-effector coupler and the multi-link system. In some embodiments, the changes in link length may be correlated to the position of the actuator.

摘要： A displacement amplifier receives an actuation displacement signal from a piezoelectric actuator. The displacement signal is amplified by one or more stages of compliant elements, and a corresponding force is applied to a load. Wide frequency response is achieved in response to the resilience characteristics of the compliant elements that are formed from any of several materials, illustratively aluminum, steel, titanium, plastics, composites, etc., and are produced by any of several manufacturing techniques, illustratively extrusion, die casting, forging, etc. The compliant elements can be configured as plural compliant mechanical displacement amplifier stages. In bilateral arrangements displacement signals from distal ends of the motive source are applied to symmetrical, or mirror image, arrangements of compliant elements. The motive source, which may be a piezoelectric actuator, delivers its displacement signal at one end thereof to one or more compliant elements. The other end of the piezoelectric actuator can be grounded.

The monolithic frame defines a longitudinal axis between opposite first and second ends thereof, and is adapted to receive the flexible drive shaft of a surgical tool, and to support at an end thereof the rotary cutting tool of a surgical tool. The monolithic frame is characterized by greater flexibility in opposite directions along a first axis defined normal to the longitudinal axis than in opposite directions along a second axis defined normal to both the first axis and the longitudinal axis.
