The first step in girth gear alignment is preparation. The equipment must be shut down and deenergized, and safety protocols should be followed. Once safety measures are in place, the equipment should be cleaned, and any debris or dirt removed. The second step is measuring the alignment of the girth gear and pinion.
II84 The pinion and girth gears of two 9 MW ball mills exhibited severe scoring within . and the gears would appear to be out of alignment even if their mechanical . II84 gears on both ball mills exhibited excessive excursions in the thermal . alignment, that is, the pinions were now misaligned in the opposite direction.
By delivering the lateral gear drive together with the girth gear, we ensure that both components match perfectly. Our girth gears have a key role in meeting the highest power demands in vertical rollers mills. The MAX Drive powers vertical roller mills up to 15,000 kW with two spur gear drive units that mesh with the girth gear under the mill ...
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.
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.
The girth gear is one of the more commonly used parts in large mechanical equipment (such as rotary kiln, ball mill). Its function is to transmit and change the direction of force through the large ring gear. The large ring gear belongs to the thinwalled ring castings. ... To complete the installation and alignment of the girth gear with high ...
