High Precision Helical Gears for Industrial Transmission Systems

The helical gears shown are precision-machined transmission components designed for smooth, high-efficiency power transfer in demanding industrial applications. Manufactured with tight tolerances and superior surface finishing, these gears ensure stable torque transmission, reduced vibration, and extended service life.

Engineered for performance and reliability, they are ideal for high-speed and heavy-load operating environments.

Key Features

✔ Precision Tooth Geometry
Optimized involute tooth profile ensures accurate meshing, reduced noise, and improved load distribution.

✔ Smooth & Stable Operation
Helical tooth design provides gradual engagement, minimizing impact force and enhancing transmission smoothness.

✔ High Load Capacity
Designed to handle medium to heavy torque loads with excellent structural rigidity.

✔ Superior Surface Finish
Ground or precision-machined tooth surfaces improve wear resistance and operational efficiency.

✔ Consistent Batch Quality
Strict dimensional control guarantees uniformity across large-volume production.

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!
