Large module gears refer to gears with a larger module. The module is a basic parameter in gear design, which defines the size of the gear teeth. The larger the module, the larger the teeth of the gear, and the gear itself will be larger and stronger. Here are some of the main features of large module gears:

• Larger teeth: Large module gears have wider tooth spaces and thicker teeth, which allows them to withstand greater loads.
• High strength: Due to their larger teeth, large module gears are generally stronger and can withstand greater forces without being easily damaged.
• Good wear resistance: The tooth surface of a large module gear is larger, so when meshing with another gear, the pressure per unit area is smaller, which helps to improve the wear resistance of the gear.
• High accuracy requirements: Since large module gears are often used in precision and large machinery, the manufacturing accuracy of gears is very high.
• Wide range of applications: Large module gears are often used in heavy industry, mining, large machinery and equipment, such as excavators, cranes and large transmission systems.
• Noise and vibration: Due to the large teeth, greater noise and vibration may be generated when meshing, so special attention is required to shock absorption and noise reduction measures.
• Design and manufacturing costs: Due to the size and accuracy requirements of large module gears, their design and manufacturing costs are usually higher.

Our company was formerly known as Changsha Double Star Gear Industrial Co., Ltd, which was established in 1994. It is a directly affiliated university-run enterprise founded by Central South University Professor Zeng Tao, the leading expert on spiral bevel gears in China. It was later renamed as Changsha Senjie Gear Co., Ltd (abbreviated as "CSG") in 2016. CSG is a production R&D base specializing in professional design, reserch, manufacture and sales of high-quality small module spiral bevel gears and high reduction hypoid gears and cylindrical gears. In 2023, Hunan Dinghan New Material Technology Co., Ltd. was established as a specialized international export business department. CSG has strong scientific research and development capabilities and is also equipped a full set of advanced equipment including seven-axis five-linkage CNC spiral bevel gear grinding machines and gear milling machines. By making the best use of the scientific and technological achievements and equipment of the Gear Research Institute of Central South University, machanical processing, heat treatment and testing. We have developed high-quality products featuring high reduction, high speed, heavy load, low noise and less teeth for users.

With the quality policy of "scientific and technological innovation, quality first, being first-class firm and customer‘s satisfaction", we have won the trust of well-known domestic and abroad enterprises with stable and excellent quality. It is committed to be a pioneer of the industry of China's small-module spiral bevel gears, and is dedicated to providing service for any related industry requiring industrial robots, CNC turning and milling compound power tool turrets, industrial sewing machines, reducers, bicycles, power tools and aeromodelling. We sincerely look forward to your cooperation!
