Description

Girth gear also called gear ring, ball mill girth gear, kiln girth gear, is one of the main parts of a rotary kiln and ball mill. The girth gear needs to drive the whole cylinder to run for a long time, so the casting quality of the girth gear is required to be high.

Due to the large modulus and diameter of the girth gear, the girth gear processed by DEYU adopts a spoke plate structure, which is composed of two semi-tooth rings.

The operation steps of the large-scale girth gear casting process are controlled by special personnel, and the entire processing process is relatively fine, especially the gear running in has higher requirements for the process, so special attention should be paid during processing, and the products must pass strict strictures. Only after testing can it leave the factory.
