The large girth gear of the ball mill not only has a large shape, but also has a certain weight. It is formed by combining two half-toothed gears, which is mainly for the convenience of disassembly and installation. The number of teeth of the large ring gear is generally even, and it needs to be opened on the tooth groove.

Girth gears (Gear wheels) are large ring gears which are normally fitted to the outside of ball mills or rotary kilns to provide the primary rotational drive,which is required to be operated in a long time So, the quality requirements during the actual production for the big gear ring are very high Girth gears are applied in the mining, cement, minerals industries used in various types

Industrial gear units girth gear series Girth gears are used to drive large, rotating systems such as dryers, rotary kilns or horizontal mills. The flexible concept from SEW-EURODRIVE has simplified manufacturing, transport and assembly.

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
