Girth gear and pinion are two of the most crucial components in cement making machinery such as rotary kiln and cement ball mill. They play a pivotal role in ensuring the smooth operation of the machinery and directly impact the quality and efficiency of the cement production process. The girth gear is a large ring gear that is mounted on the ...
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.
