    摘要： A variable wobbler plate has a stub shaft and a pivot shaft. The pivot shaft has a smaller diameter portion and a larger diameter portion. The smaller diameter portion has a generally cylindrical outer periphery with a flat over a limited circumferential extent and a diameter to opposed portions of the generally cylindrical portion defining a first distance. A second distance is defined from an end of the smaller diameter portion spaced furthest from the stub shaft to an end of the larger diameter portion spaced closest to the stub shaft and measured along a central axis of the pivot shaft and defines a second distance. A ratio of the first distance to the second distance is between 0.60 and 0.75. An integrated drive generator and a method are also disclosed.

    摘要： Infinitely variable motion control (IVMC) using Transgear gear assemblies provides rotary motion control without any requirement for connecting or disconnecting gear meshes or use of a clutch. A bevel, miter, ring or spur gear Transgear gear assembly may be defined as a gear assembly having three or four of variables, input, output and control, assigned in a manner so as to provide, for example, one of accumulation of inputs and direction control. A four variable Transgear gear assembly may be one of a spur gear Transgear gear assembly having an additional ring gear surrounding a set of planetary gears or a bevel gear Transgear gear assembly having a double bevel gear, an outer bevel gear and a bevel gear meshing to the outer bevel gear sleeve surrounding an inner beveled gear and comprising three orthogonal carrier shafts. Rather than two sets of three variable Transgear gear assemblies connected in series or in parallel, a four variable Transgear gear assembly may provide, for example, a direction control function with just one gear assembly with two of the four variables assignable as control variables.

    摘要： A gas turbine generation system has a three-phase generator whose rotor is mechanically coupled to a gas turbine. The system comprises a three-phase voltage balancing circuit having elements independently operable for each phase to disperse or cancel unbalanced components of three-phase current, during unbalanced fault in a power grid connected to the generator, result in balancing of the three-phase voltage; and the voltage balancing constitutes a mechanism of avoiding the occurrence of the rotor vibration from mechanical resonance points on turbine blades.
