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 mills and ball mills for use in the mining and cement industries.girth gear failures. inspections of the gear teeth are necessary to detect crack formation, spalling, severe wear and other potential failures. girth gear system function. To rotate a cylindrical drum by transferring and increasing torque from a high speed shaft to a low speed girth gear. girth gear functional failure. gear cannot transfer torque.large girth gears are used where heavy loads need to be carried in rotary tubular kilns, tube mills, and winches at sea. As the dimensions of such gears can be huge, it is often difficult to protect the gear teeth effectively against external media. In contrast to enclosed gears, dirt, abrasive cement and coal dust and salt water may enter the

Girth Gear Inspection Pre And Post Manufacture

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 proper alignment should consist of: axial and radial alignment of the girth gear to the center line of kilnmill; center line of the driving pinion is aligned to the center lineapr 24, 2011 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.the identification of mechanical vibrations due to backlash phenomena appearing between the pinion gear and the girth gear rim of the kiln is realized using the motor current signature analysis
