Here are some key functions of gears in aircraft models:

• Gearbox Applications: Aircraft models often incorporate gearboxes that consist of multiple gears and shafts. Gearboxes enable the distribution and control of power among various systems, such as the main rotor, tail rotor, landing gear, or auxiliary systems.
• Control Surfaces: Gears can be used to actuate control surfaces, such as flaps, ailerons, elevators, or rudders, in aircraft models. They convert the rotational motion from actuators or hydraulic systems into the desired linear or angular movement of the control surfaces.
• Landing Gear: Gears are crucial components of the landing gear system in aircraft models. They support the weight of the aircraft during takeoff, landing, and taxiing, providing stability and shock absorption. Landing gear gears may include mechanisms for retracting and extending the landing gear .
• Auxiliary Systems: Gears are employed in various auxiliary systems within aircraft models. They can be used in systems such as hydraulic pumps, fuel pumps, cooling fans, or electrical generators, where they contribute to driving and controlling these systems.

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!
