The girth gear is the main transmission component of the ball mill and the rotary kiln. The girth gear is usually large in modulus and diameter, and generally adopts a radial structure, which is composed of two half gears. This structure determines that the girth gear will produce deformation during processing.

CHAENG has a history of manufacturing girth gears for many years. It has accumulated a lot of experience in long-term production and has formed a complete set of girth gear processing technical solutions that can provide customers with manufacturing service for girth gears with a diameter of 2m-12m.

In order to prevent the deformation of the girth gear during manufacturing, CHAENG usually adopts the following methods:

1. Before casting, CHAENG will use computer simulation technology to digitally simulate the girth gear casting process, which can well predict the problems that will occur in the casting process and complete the optimization of the girth gear casting process.

2. CHAENG will conduct non-destructive inspection to ensure the quality of the girth gear.

3. CHAENG adopts a unique heat treatment process, which makes the girth gear have good comprehensive mechanical properties. It has good plasticity and toughness while maintaining high strength, which can prevent the large gear from deforming;

4. Determine the reasonable cutting amount, especially in the finishing turning and gear hobbing processes.

5. Choose a reasonable clamping method, and in the process of lifting the workpiece, select the stress point reasonably to prevent the lifting deformation.

At present, CHAENG has sold the girth gears over the country, and has been well received by customers!
