Product Introduction

Girth gear is also called girth ring gear. It is a main spare part that is mounted around the body of cement ball mills or rotary kilns. The girth gear drives the cylinder of mills or kilns and is required to be operated for a long time. The quality of the girth gear is essential since it affects the balance and stability of the drive system.

SINOMA can produce high-quality girth gear according to the sizes, parameters, etc. required by customers. We design the casting process through simulation software to make sure the precision of the production. The manufacturing process is strictly controlled by our workshop through every step. We pay special attention to heat treatment for the key process. The ball mill gears and other kinds of gears are produced in two segments or more upon request.

Advantages of SINOMA ball mill girth gear

Higher wear resistance

SINOMA adopts a special heat treatment of the tooth surface of the large gear to further improve the hardness, wear resistance, and impact resistance of the tooth surface.

Higher precision

CAE software is used to digitally simulate the pouring system in the casting process to ensure the quality of the product. The finishing of the steel castings adopts arc air gouging, shot blasting, and other technologies to ensure the appearance quality of the steel castings.

Longer lifetime

High-strength steel is used for casting the girth gears to meet a long-time working demand. It is not easy to deform and has a better carrying capacity.

Strict quality testing

The introduction of physical and chemical testing facilities such as GS1000 direct reading spectrometer, carbon and sulfur high-speed analyzer, digital ultrasonic flaw detector, and multi-purpose magnetic particle flaw detector from German OBLF company ensures that the product components are qualified.

SINOMA girth gear manufacturing process

The girth gears are produced following the drawings provided by customers. We also offer drawing optimization services and technique support.

The machining process of girth gears includes the following steps: gear blank machining, tooth surface machining, heat treatment process, and tooth surface finishing.

The first step in the machining process of the large gear is that the gear blank enters the machining process. At this time, it is mainly to prepare the basis for the next processing of the tooth shape, so that the accuracy of the inner hole and the end face of the large gear meet the specified technical requirements.

The second step is the machining of the tooth shape, to achieve the specified hardness requirements.

Then there is the finishing of the tooth shape, mainly to make the positioning reliable, and the distribution of the allowance is relatively uniform, to achieve the purpose of finishing.

The last step is to heat treatment the large gear so that the structure of the large gear is optimized, the hardness is improved, and the wear resistance and impact resistance of the product is greatly enhanced.
