The girth gear driving pinion ends up getting aligned to the reducer, causing a misalignment issue between the girth gear teeth and the driving pinion teeth (Fig. 1). Proper alignment should consist of: axial and radial alignment of the girth gear to the center line of kiln/mill; center line of the driving pinion is aligned to the center line
There are three ways to align the pinion skew to the girth gear; 1) Using the pitch lines 2) Setting root clearance 3) Setting backlash (only applicable to a new gear and pinion). Measuring the root clearance is best done using Babbitt or lead slugs. Use % 1" diameter Babbitt slugs about 1 to 2" in length.

Girth gears are now being used to drive ball and SAG mills having total installed power in excess of 17,000 kW (23,000 hp). The development of highhardness materials suitable for these applications has resulted in the design and manufacturing of cast girth gears up to 350 HBW in steel and 340 HBW in ductile iron.
2. Remove the rotary kiln girth gear. When one of the semicircle gears of rotary kiln rotates to the top, remove the pinion to separate the girth gear from the drive system, and remove the bolts after making marks. Then use the winch to rotate kiln body, remove the other half girth gear. At the same time, make sure to prevent spring plate from ...
