kiln girth gear backlash

backlash in ball mill gear pinion

The girth gear driving pinion ends up getting aligned to the reduc-er, 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

Girth Gears - More than Just Metal and Teeth

Girth Gear Applications Girth gears fall into two basic categories; flange mounted and tangential spring mounted. Flange-mounted girth gears, the more common of the two, are most frequently utilized in “cold” processing equipment such as SAG (semi autogenous grinding) mills and ball mills for use in the mining and cement industries.

Gear Backless Calculation - CR4 Discussion Thread

If backlash is an issue, and if your system dimensions can accommodate it, you could consider an anti-backlash pinion. One way of doing this is to mount a second pinion in tandem with the first, with spring loading so that the pinion teeth "push apart" to fully occupy the spaces within the girth gear.
