ABSTRACT:
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.
