Precision Spiral Bevel Gear Set: Engineered for Optimal Power Transmission

Spiral Bevel Gear Set – High Precision Right Angle Transmission Solution

The spiral bevel gear set represents the pinnacle of precision engineering in power transmission components. Comprising a spiral bevel gear and a pinion shaft, this assembly is designed to deliver smooth, efficient torque transfer at 90° angles, making it indispensable for applications demanding high accuracy, low noise, and robust durability.

Technical Excellence

• Design & Geometry: The spiral teeth feature a curved profile that meshes gradually, reducing impact loads and minimizing operational noise. This spiral design also enables higher load-carrying capacity compared to straight-bevel alternatives.
• Material & Hardness: Fabricated from premium alloy steel, the gears undergo precision heat treatment (e.g., carburizing, quenching) to achieve a surface hardness of HRC 58–62, ensuring exceptional wear resistance and fatigue strength.
• Manufacturing Precision: Employing advanced CNC gear cutting and grinding technologies, the gear set meets AGMA Class 10–12 standards for tooth profile, pitch, and surface finish, guaranteeing seamless meshing and long-term reliability.

Application

1. Automotive: Differential drives, power steering systems, and specialty vehicle transmissions.
2. Aerospace & Defense: Actuation systems, rotorcraft components, and mission-critical machinery.
3. Industrial Equipment: Robotics, CNC machines, packaging systems, and heavy-duty conveyors.
4. Marine & Offshore: Propulsion systems, winches, and offshore drilling equipment.
   

Key Specifications

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!
