High Torque Servo Gear Reducer Hollow Shaft Rotary Actuator Harmonic Drive Systems Actuators

Hollow Shaft Rotary Actuator Harmonic Drive Systems High Torque Servo Actuators Industrial Reducer

Harmonic Drive actuators, also known as Harmonic Drive servo actuators or Harmonic Drive gearheads, offer several characteristics and advantages, including:

• High Precision: Harmonic Drive actuators are known for their exceptional precision due to the unique strain wave gear mechanism they employ. This mechanism enables precise positioning and repeatability, making them suitable for applications that require accurate motion control.
• Compact Design: Harmonic Drive actuators are designed to be compact and lightweight compared to other types of gear systems. This compactness allows for space-saving integration into various systems and applications where size constraints are a concern.
• High Torque Transmission: Harmonic Drive actuators can provide high torque output relative to their size. The strain wave gear mechanism enables efficient torque transfer, allowing for increased power transmission in a compact form factor.
• Backlash-Free Operation: Backlash refers to the clearance or play between gear teeth, which can affect positioning accuracy. Harmonic Drive actuators are known for their minimal or zero backlash operation, ensuring precise and reliable motion control.
• High Gear Reduction Ratios: Harmonic Drive actuators can achieve high gear reduction ratios in a single stage, reducing the need for multiple gear stages. This simplifies the overall system design and improves efficiency.
• Smooth and Silent Operation: Harmonic Drive actuators operate with reduced noise and vibration, providing smooth and quiet motion. This characteristic is beneficial for applications where noise reduction is important, such as in robotics or medical devices.
• Customization: Harmonic Drive actuators can be customized to meet specific application requirements. They are available in various sizes, torque capacities, and configurations, allowing for tailored solutions to fit different applications.

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!
