Girth gear

Processing Weight: ≥5T

Materials: ZG45、ZG42CrMO

Application: cement, metallurgy,  building materials, and other industries, etc. 

Girth gear also called gear ring, ball mill girth gear, kiln girth gear, is one of the main parts of a rotary kiln and cement 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 AGICO CEMENT adopts spoke plate structure, which is composed of two semi-tooth rings.

Production process of girth gear

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.

According to customer requirements, AGICO selects suitable wooden molds for modeling design and uses Huazhu CAE to simulate pouring before pouring. Gear ring castings are cast in strict accordance with the following process:

Wood mold – modeling – smelting-pouring – heat preservation – heat treatment – inspection – teeth making – packaging and delivery process

Working principle of girth gear

Ball mill girth gear

The girth gear of the cement mill is mainly driven by the motor and the small gear drives the big gear mounted on the cylinder, so that the cement mill is driven, the big gear and the cylinder are combined.

Kiln girth gear

At the same time, the girth gear is also one of the key components of the rotary kiln, its installation quality directly affects the stability of the rotary kiln transmission system, the stability of the operation of the rotary kiln, the service life of the kiln lining and the rotary kiln operation rate.
