Abstract
A BACKLASH ADJUSTMENT MECHANISM FOR USE IN A VARIABLE PIPE DIFFUSER (14) HAVING INNER AND OUTER RINGS (40,42) AND A CASING.THE BACKLASH ADJUSTMENT MECHANISM INCLUDES A DRIVE SHAFT (19) AND A PINION GEAR (124) ATTACHED THERETO,A RACK GEAR (123) FIXEDLY ATTACHED TO THE INNER RING (40).THE BACKLASH ADJUSTMENT MECHANISM IS COMPRISED OF A HOUSING (31) HAVING A CYLINDRICAL BODY POSITIONED CONCENTRICALLY ABOUT A FIRST CENTERLINE AND HAVING A BORE DISPOSED AXIALLY THROUGHT THE BODY POSITIONED ABOUT A SECOND CENTERLINE.THE DRIVE SHAFT (19) IS ROTATABLY DISPOSED CONCENTRIC WITH THE SECOND CENTERLINE WITHIN THE BORE.THE INNER RING (40) IS POSITIONED SUCH THAT IT MESHES WITH THE PINION GEAR (124).THE HOUSING (31) IS DISPOSED WITHIN THE CASING AND ROTATABLY OPERABLE TO EFFECT AN ADJUSTMENT OF THE BACKLASH BETWEEN THE PINION GEAR (124) AND THE RACK GEAR (123).(FIGURE 10)
