    摘要： A welding wire feeding apparatus with orbital mounting assembly for use in combination with an industrial manipulator of the type including a "Z" axis assembly from which there is dependingly supported an extended welding axis post for rotational movement about the "Z" axis. The improved welding wire feeding apparatus mounting assembly is rotatably mounted on the bottom of the "Z" axis or wrist assembly of the robot and is in communication with the extended axis post by a rubber-lined yoke so that the rotational movement of the orbital welding wire feeding apparatus is simultaneous with that of the extended welding post. As a result of a support bearing and the attachment through a rubber-lined yoke, no mass or stiffness coupling occurs between the wire feeding apparatus and the extended axis post so that the natural frequencies of the extended axis post remain unchanged.

    摘要： A dynamoelectric machine utilizing stiff, multiple component phase leads for connecting potentially misaligned stator coils and parallel phase rings. The phase leads, when attached to stator coil and phase ring coolant headers, provide electrical communication therebetween. The first and second phase lead components have a hole and cylindrical portion respectively wherein the cylindrical portion is insertable in the hole. Such phase lead hole has a longitudinal axis perpendicular to both slot elongation directions. Intimate electrical contact between the phase lead components and their connected coolant headers is insured by disposidng solder between their mateable, plane surfaces. Intimate electrical contact between the phase lead components is insured by brazing the components together at the interface between the assembled cylindrical portion and hole. Translational misalignment between the connectable phase ring and coil is accommodated in the three perpendicular directions by providing the slotted openings and permitting insertion of the cylindrical phase lead portion into the phase lead hole for selected distances. Such selective insertion is obtained by supplying extra stock to the cylindrical phase lead portion and trimming that portion to the appropriate length at assembly time.

    摘要： A fluidly cooled flat plate neutral bus for electrically connecting the neutral bushings on dynamoelectric machines. The current carrying flat plate is in heat transmissive contact with a coolant carrying conduit which transfers heat generated in the neutral bus to the coolant flowing therethrough. The fluidly cooled flat plate neutral bus provides high heat flux while occupying a small volume.BACKGROUND OF THE INVENTION1. Field of the Invention:This invention relates to the neutral bushings on dynamoelectric electric machines, and more particularly to means for electrically connecting those neutral bushings and means for cooling the electrically connecting means.2. Description of the Prior Art:Large turbine generators often have several (three for a three-phase machine) neutral lead bushings which are electrically connected by a bus. Several schemes have been utilized in the past to remove the heat generated in the bus as a result of the current flow therethrough during generator operation.For some small generators satisfactory cooling of the bus was obtained by natural convection while larger machines required a forced convection air flow to maintain the bus at an acceptable temperature. More recently, buses on certain, selected generators were altered to accommodate still higher amperage ratings in those generators. These buses were typically water cooled members having rectangular cross sectioned copper current carriers within which stainless steel piping was brazed. Through the stainless steel piping or other suitable material coolant was transmitted which was effective in carrying away heat generated in the current carrier. This internally cooled neutral bus was acceptable for generators rated at less than 34,000 amperes. However, this design was no longer practical for a variety of reasons in machines whose ratings were larger than 34,000 amperes. Space limitations set by attachment requirements between the bus and the bushings prohibit additional coolant carrying pipes. Enlargement of the current carrier to accommodate an increased number of coolant carrying tubes would cause an increased cantilever type load to be imposed upon the attached neutral bushings. Such increased load could damage the bushings or adversely affect the performance of the entire generator. A neutral enclosure surrounds and isolates the neutral bushings and their connecting bus from the atmosphere. The purpose of the neutral enclosure is to prevent damage to and contamination of the bushings while shielding the electrically charged bushings and bus from any possible human contact. Any increase in the size of the rectangular current carrier bus must be reflected in a concomittant increase in the size of the neutral enclosure which surrounds that bus. Increasing the size of the neutral enclosure requires additional material and, more importantly, additional space in the power plant central station.A further method for increasing the heat transfer rate from the neutral bus is to increase the coolant velocity through the stainless steel piping. However, for generator ratings higher than 34,000 amperes the required coolant velocity through the spatially limited maximum number of allowable stainless steel tubes becomes excessive resulting in possible tube erosion and drastically increased coolant pumping power. Such tube erosion can contaminate the nonconductive coolant and bring about forced turbine-generator outages while the excessive pumping power consumption can cause uneconomical operation.It is thus apparent that a new design of bus is required which will increase the heat transfer capabilities and preferably decrease the space occupied by the old model bus.SUMMARY OF THE INVENTIONIn accordance with the present invention, an improved neutral bus is provided for electrically connecting the neutral bushings in dynamoelectric machines. This invention generally comprises an electrical winding which has internally cooled neutral bushings connected thereto, a multiple plate electrically conductive bus which is connected across those neutral bushings by flexible conductors disposed between the plates, and a plurality of coolant conduits attached to the plates for cooling the bus.The conduits carry coolant therethrough and are joined to the plates in a heat conductive fashion. The coolant conduits are preferably joined to the bushing's internal coolant passages by flexible hoses. Further increases in generated heat from larger rated machines can be carried away by suitable selection of the number of conduits per bus plate member, size of the conduit, relative disposition of the conduit and plate member, and coolant velocity through each conduit. The weight and volumetric requirements of the present invention amount to 50% and 80% respectively of the previously utilized bus.
