A mechanical joint configured for providing dissipation of heat generated is provided. The mechanical joint includes a housing containing a motor assembly configured to drive a gear assembly for driving the mechanical joint, the motor assembly configured to be controlled by a control assembly for controlling rotation of a rotor of the motor assembly; wherein a brake disk of the control assembly is configured to increase air flow within the housing. A robot and a robotic system are also disclosed.

A seal has a non-woven fabric folded along lines transverse to the opposite side of the seal and secured by adhesive to fabric strips. The non-woven fabric forms elongated cells with a plurality of the cells receiving inserts to increase seal stiffness. By securing one of these strips to a stationary component of the sealing surfaces, the opposite strip may expand or collapse relative to a movable sealing surface to accommodate excursions of that surface. Multiple layers of cells may be provided in the seals. The inserts may have various cross-sectional configurations including circular, triangular or rhombic and formed of tubes, solid rods or coiled springs.

Apparatus () controls net thrust in a steam turbine (T) in response to changes in the operating condition of the turbine. The turbine includes a thrust bearing (B) positioned between low and intermediate pressure sections (LP, IP) of the turbine and a high pressure section (HP) thereof. Sensors () for sense thrust loads on the thrust bearing. A number of control valve (CV-CV) are used to balance pressures occurring at locations within the high pressure section of the turbine. A controller () is responsive to the sensors sensing a change within the turbine indicative of a significant change in net thrust to energize one or more of the control valves and to adjust the pressure within the high pressure section of the turbine so to maintain net thrust within an acceptable range of thrust values.

A generator gas shield includes an annular ring body having an outer radially extending flange terminating at a first free end of a first diameter; a curved inlet portion; a substantially axial portion surrounding a center opening, and a curved outlet portion terminating at a second free end of a second diameter smaller than the first diameter.

Generator gas shield and related method

A combined brush/labyrinth tooth seal is provided between a gas shield and the fan tips in the ventilation system of an electrical generator. At least a pair of brush seals straddle a labyrinth tooth providing a close or zero radial clearance with the tips of the fan blades. The brush seals are provided in two double-row bi-directional form. In one embodiment, the brush bristles are slanted toward the fan in a generally axially opposite direction. In a further embodiment, the slanted brush seals engage either the opposite sides of the fan blades or the fan blade tips.

Sealing apparatus for electrical generator ventilation system

A ventilation pathway for a cooling gas to flow extends on a radial axis in a generator stator core. The ventilation pathway comprises at least two magnetic laminations and a plurality of space blocks extending radially in the generator stator core. The space blocks are fastened and disposed between the magnetic laminations. At least one of the space blocks includes a wavy longitudinal profile that includes an alternating pattern of peaks and valleys with respect to the radial axis of the generator stator core. Alternatively, at least one of the space blocks has a plurality of protrusions defining a pattern of peaks and valleys extending from a sidewall of the space block. Several different shapes of vortex generators are punched in the lamination are located within the ventilation pathway.

A magnetic armature wedge is provided for replacing conventional dovetail wedges in high-powered large-size turbine generators. The magnetic armature wedges that are used for supporting the armature bars are made by molding resin, e.g., epoxy with ferromagnetic particles, wires, laminates and the like embedded therewithin. The magnetic particles, wires, laminates and the like increase the magnetic permeability of the wedges causing higher slot flux leakage and high generator subtransient reactants.

A brush seal assembly that in an exemplary embodiment includes an elongate brush core holder, at least three elongate brush core packs bundled together side-by-side in the brush core holder forming a single assembly. Each brush core pack includes a bristle holder and a plurality of bristles coupled to the bristle holder.

Multi-core brush seal assembly for rotary machines

A technique for enhancing heat transfer ventilation grooves is provided which allows the cooling groove dimensions to be minimizes while satisfying endwinding cooling requirements. Groove dimension may be minimized by including surface manifestations and/or selecting a non-linear groove configuration or shape to enhance heat transfer.

A seal as a non-woven fabric folded along lines transverse to the opposite side of the seal and secured by adhesive to fabric strips. The non-woven fabric forms elongated cells. By securing one of these strips to a stationary component of the sealing surfaces, the opposite strip may expand or collapse relative to a movable sealing surface to accommodate excursions of that surface. Multiple layers of cells may be provided in the seals. Additionally, to increase seal stiffness, inserts may be extended into one or more of the cells.
