Positionierantriebsvorrichtung mit Spieleinstellung für variablen rohrförmigen Diffusor

摘要

A backlash adjustment mechanism comprises a housing 130 having a cylindrical body positioned concentrically about a first centerline 127 and having a bore 129 disposed axially through the body positioned about a second centerline 131. A drive shaft 126 is rotatably disposed concentric with the second centerline within the bore. An inner ring is positioned such that it operably engages a pinion gear 124. The housing 130 is rotatably operable to effect an adjustment of the backlash between the pinion gear 124 and a rack gear 123.
