Descriptions

As a girth gear manufacturer, we always build full-chain capabilities with strict standards and are determined to become a reliable cornerstone in the equipment manufacturing field.

In the material processing, we have established a strict material organization and control system. We carefully select high-strength alloy steel from the source. We use professional methods such as spectral analysis and metallographic testing to ensure that the materials meet the standards and resolutely prevent inferior raw materials from entering the production process.

In terms of processing, we have accumulated rich experience in CNC processing and are equipped with multiple high-precision CNC vertical lathes, gear hobbing machines, large gantry milling machines, large floor-type boring machines and other advanced equipment. Relying on mature process parameters and a team of professional technicians, we accurately control key dimensions such as the gear ring tooth shape and module to fully guarantee the processing accuracy of each product.

In terms of testing system, we have achieved complete coverage of the entire process, from rough flaw detection to hardness testing and runout testing of finished products, all of which are fully verified using professional equipment such as three-dimensional coordinate measuring machines.

The assembly team is highly professional and familiar with the assembly requirements under different working conditions. Through precise alignment and torque control, they ensure that the gear ring and the equipment are perfectly compatible.

At the same time, we have also established an efficient after-sales service team to provide customers with full-cycle support such as installation guidance and troubleshooting, and promptly respond to every need. Our full-chain professional capabilities have built a solid industry reputation.

In order to adapt to the needs of the girth gear to withstand high stress, wear resistance and adapt to harsh working conditions, we will select materials with different characteristics: in pursuit of strength and toughness to cope with the high load of large industrial machinery, we will choose cast steel; in order to extend the life of the gear with good wear resistance, machinability and vibration and noise reduction capabilities, we will choose ductile iron; because the ring gear needs to withstand extreme stress and impact, we will choose forged steel, which is stronger than cast steel; in order to obtain higher hardness, strength and wear resistance to adapt to heavy-load scenarios, we will choose alloy steel with added elements such as nickel and chromium; in applications with lower requirements, in order to take into account cost-effectiveness and basic wear resistance, we will choose cast iron, which is not as strong as steel but has a high cost performance.

Machinery Processing

Due to their large size and weight, girth gears are typically manufactured in sections. This process primarily involves turning, milling, and drilling, supplemented by heat treatment and precision grinding for final assembly. The specific process is as follows:

First, the blank is machined in sections. Turning is used to rough-turn the inner hole, outer diameter, and end faces of each section to ensure surface accuracy. Milling is then used to create the tooth profile, initially shaping the ring gear's tooth structure. Drilling is also used to create auxiliary holes, such as connection holes and locating holes, in preparation for subsequent assembly.

This manufacturing process requires tempering heat treatment, which involves quenching and high-temperature tempering to improve the material's overall mechanical properties and enhance the ring gear's strength and toughness. After basic machining is complete, the tooth surfaces are precision ground to eliminate milling errors, improve tooth surface finish and meshing accuracy, and ensure transmission stability.

Finally, the sections are precisely aligned through locating holes and bolted together using the connection holes. After assembly, the overall roundness, coaxiality, and pitch deviation are inspected to ensure the large ring gear meets overall operational requirements.
