Abstract: A disconnect mechanism includes an input shaft defining a drive axis. A disconnect shaft is selectably engaged with the input shaft to be driven about the drive axis by the input shaft. A disconnect ramp shaft is operatively connected to the disconnect shaft to axially move the disconnect shaft between a first axial position wherein the disconnect shaft is engaged to the input shaft and a second axial position wherein the disconnect shaft is disengaged from the input shaft. The disconnect ramp shaft includes a ramp defined around an outer surface thereof. A disconnect pawl is selectably engaged with the ramp of the disconnect ramp shaft to engage or disengage the disconnect shaft from the input shaft.

Abstract: An input shaft includes an annular main shaft extending along a longitudinal axis with an internal bore configured for fluid flow through the annular main shaft. A generator spline is included on an exterior surface of a first end of the main shaft. A gearbox spline is included on an exterior surface of a second end of the main shaft opposite the first end. At least one orifice is defined through the main shaft from the internal bore to the exterior surface of the second end of the main shaft for flow of fluid from the internal bore to the exterior surface for cooling and lubrication.

Abstract: An assembly comprises a resistor plate for a rotating rectifier assembly (RRA). A shaft bore is defined through the resistor plate for passage of a shaft of an electrical machine, and the resistor plate defines a main annular body around the shaft bore. A first protrusion extends radially outward from the main annular body, so that a first pin bore extends through the first protrusion. At least one contact band is seated in a the pin bore of the resistor plate for mounting a direct current (DC) pin to the resistor plate.

Abstract: A lamination for use in an integrated drive generator is formed from a plurality of plates having a body including a pair of opposed cylindrical surfaces. Non-cylindrical ditches are defined circumferentially intermediate the pair of cylindrical surfaces. A plurality of passages are formed in an outer periphery of the cylindrical surfaces including relatively large holes extending through a slot to the outer periphery. Grooves are formed intermediate the relatively large holes.

Abstract: A terminal assembly includes a terminal block of a dielectric material defining a plurality of bores therethrough. A respective terminal contact of an electrically conductive material is seated in each of the respective bores. The terminal contact defines a longitudinal axis therethrough with a terminal bore defined through the terminal contact along the longitudinal axis. A divider wall separates the terminal bore into a solder cup for a lead wire on an interior side of the terminal bore, and a lug receptacle on an exterior side of the terminal bore.

Abstract: A port plate for use in an integrated drive generator has a body defining a semi-cylindrical charge port communicating with two circumferentially smaller charge port portions. A diametrically opposed working pressure port has three smaller working pressure ports. A center plane is defined extending through a center axis of a bore within the body and equidistance between circumferential ends of the charge port and the working fluid port. A first angle is defined between the plane and a circumferential end of the smaller charge port. The first angle is between 15 and 25 degrees. An integrated drive generator and a method are also disclosed.
