<p>A rack and pinion arrangement includes rack and pinion rods having a carrier bar, a guide bar and inner rack and pinion teeth for interaction with a driving sprocket. An end tooth at both ends of the each rack and pinion rod has a change in radius of curvature, and the tooth profile of the inner rack and pinion teeth has a change in radius of curvature. The change in radius of curvature of the end teeth is lower than the change in radius of the inner rack and pinion teeth. The end tooth head of the end teeth is lower than the tooth heads of the inner rack and pinion teeth. The end tooth in the region of the change in radius of curvature has a greater tooth width than the inner rack and pinion teeth in the region of the change in radius of curvature.</p> |
