Technical Description
Technical description:
Gear’s manufacturing, adjusting and installation is good or bad, is one of the key conditions of ball mill can be work correctly.
Structure of the large scale ball mill gear wheel:
The large scale gear ring on drive ball mill, which normally is formed by two halves of gear ring for convenient to dismantle due to large-ring shaped and heavy weight. The number of teeth is even and the opening is on the gear groove, the two halves of gear ring must be
fit accurate.
Mounting large ring gear, commonly used with bolts fixed to the cylinder end or cover flange. Some of them with a row of bolts to fix on
the cover, cylinder flange and flange of gear ring, three of them are common used the same row of bolts, and it is not convenient to repair.
This structure is suitable for middle-small ball mill. Some of them with the two rows of bolts are fixed to the end cap and the ring gear on the same side of cylinder flange separately,
which enlarged the size of outer profile, this kind of structure is suitable for the large ball mill.

Material
Currently the material of mill ring gear is commonly used ZG270 ~ 500, ZG310 ~ 570 and alloy steel. The pinion gear use35SiMn, 45MnB, 40Cr and other materials, but need heat treatment before processing.
