摘要： A shaft deflection controller includes an input driveshaft adapted for inputting power from an engine. The input driveshaft includes an axis of rotation and a spur pinion at an end of the input driveshaft. The axis of rotation of the input driveshaft changes, relative to a frame, with deflections of the input driveshaft. Two face gears are adapted for meshing with the spur pinion of the input driveshaft. A flexible shaft stabilizing mount includes an inner sleeve portion and a mounting flange. The inner sleeve portion includes a base portion connecting the inner sleeve portion to the mounting flange and a plurality of cage spring members. The mounting flange is connected to and concentric with the inner sleeve portion. The flexible shaft stabilizing mount controls the deflection of the input driveshaft by applying forces onto the input driveshaft, which tend to resist changes in the alignment of the axis of rotation of the input driveshaft. The flexible shaft stabilizing mount is connected to a rigid frame. An inner surface portion of a stiffening ring contains a curvature and surrounds and contacts the inner sleeve portion of the flexible shaft stabilizing mount.

摘要： A concentric face gear assembly includes a first face gear having first face gear teeth and second face gear having second face gear teeth. At least one input pinion contacts both the first face gear teeth and the second face gear teeth, and at least one idler pinion contacts both the first face gear teeth and the second face gear teeth. The first face gear is adapted for directly driving a rotor, but the second face gear is not adapted for directly driving a rotor. The load carried by the first face gear includes the force needed to drive the rotor. Since it does not drive a rotor, the second face gear does not comprise a web or spline attachment and is therefore lightweight. Both the first face gear and the second face gear include thrust bearings, which are located radially outwardly of the first face gear teeth and radially inwardly of the second face gear teeth. The first face gear includes a web, which is relatively thin due to the thrust bearing of the first face gear being located radially outwardly of the first face gear teeth rather than radially inwardly of the first face gear teeth.

摘要翻译： 同心面齿轮组件包括具有第一面齿轮齿的第一面齿轮和具有第二面齿轮齿的第二面齿轮。 至少一个输入小齿轮接触第一面齿轮齿和第二面齿轮齿，并且至少一个惰轮小齿轮接触第一面齿轮齿和第二面齿轮齿。 第一平面齿轮适于直接驱动转子，但是第二平面齿轮不适于直接驱动转子。 由第一面齿轮承载的载荷包括驱动转子所需的力。 由于它不驱动转子，所以第二平面齿轮不包括腹板或花键连接件，因此是轻质的。 第一面齿轮和第二面齿轮均包括止推轴承，其位于第一面齿轮齿径向向外并且位于第二面齿轮齿的径向内侧。 第一平面齿轮包括腹板，由于第一面齿轮的止推轴承位于第一面齿轮齿的径向外侧，而不是第一面齿轮齿的径向内侧，该腹板相对较薄。

摘要： A precision grinding apparatus includes a grinding worm for precision grinding a case-hardened face gear. A shaper is first placed into contact with a face gear, to thereby shape a surface of the face gear into a plurality of face gear teeth. The shaper is then removed, and the face gear is case hardened. The grinding worm is disposed in a normal orientation to the case-hardened face gear and includes a spiral tooth extending along a perimeter of the grinding worm. The spiral tooth of the grinding worm is adapted to contact and precision grind the case-hardened gear. A dressing tool includes a protrusion for contacting the spiral tooth of the grinding worm, as the spiral tooth contacts and precision grinds the case-hardened face gear. The dressing tool thus maintains the shape of the grinding worm to within a desired tolerance range.

摘要： A conversion access gearset includes a first bevel gear, which is connected to a wing cross shaft leading from the proprotor drive train path to the second turbine engine. A second bevel gear is connected to a main transmission input shaft, which is adapted for driving the proprotor. A bevel pinion receives power from the turbine engine, and drives both the first bevel gear and the second bevel gear. An input pinion is connected between the turbine engine and the bevel pinion, and several idler gears are connected between the input pinion and the bevel pinion. A helical gear is connected between the several idler gears and the bevel pinion. The main transmission input shaft is connected to a main transmission input pinion, which is located on the main transmission input shaft opposite of the second bevel gear. The main transmission input pinion receives torque from the main transmission input shaft, and a torque-splitting device splits the torque received from the main transmission input pinion. A torque recombining system recombines the split torque from the upper face gear and the lower face gear, before routing of the recombined torque to the proprotor.
