What are the conditions for high-quality rotary kiln girth gear

24 Jun 2020 UTC+8 Views:

The girth gear, also known as the ring gear, is an important part of rotary kilns and ball mills. Its main function is to drive the entire cylinder to run for a long time. In order to ensure the use effect, it is very important to ensure the quality of the girth gear. So what conditions should a high-quality girth gear meet?

Generally, high-quality girth gear should meet the following three points:

1.High carrying capacity and smooth operation

The girth gear should have the characteristics of high bearing capacity, smooth operation and low noise.

2.Simple structure, easy to maintain

The girth gear is a split structure with two halves, and the tooth width adopts a Y-shaped structure, which is convenient for transportation and installation and ensures good rigidity of the gear.

3.Advanced technology and superior rigidity performance

The material of the girth gear is ZG45 or ZG45CrMO high-quality alloy cast steel, which is stable for a long time and has a long service life.

The rotary kiln girth gear produced by CHAENG not only meets the above conditions, but also uses a unique heat treatment technology in casting, which optimizes the girth gear structure, improves the hardness, and greatly enhances the wear resistance and impact resistance of the gear.
