As a precision manufacturer with ISO/DIN/GB Grade 5 gear manufacturing accuracy (module 0.1-5.0, tooth tip diameter 3mm-300mm) and cutting-edge equipment such as Kashifuji gear scrapers, our harmonic drive features standard backlash of ≤10 arc seconds, with customizations up to ≤5 arc seconds. Leveraging ultra-precision CNC machining (mirror-like accuracy ±0.002mm) and multi-objective optimization techniques from our experienced engineering team, we can not only meet the needs of robotic joints and precision equipment, but also provide any precision component for packaging machinery (such as tobacco packaging machines), even complete machine components!
Product Overview
Hansheng Automation's High-Performance Strain-wave Harmonic Reducers utilize a classic cup-shaped design, offering high precision and zero backlash characteristics. Unlike traditional gear transmission systems, our harmonic drives provide a higher torque-to-weight ratio. Whether you are manufacturing six-axis industrial robots or collaborative robots (cobots), our harmonic reducers ensure smooth, vibration-free motion control. Below, we will provide a detailed description of our CSF-II Integrated Series, which features our proprietary harmonic drive technology.

FAQ
Q: What is the main advantage of a strain-wave harmonic reducer over a planetary gearbox?
A: primary advantage is zero backlash and a much higher reduction ratio in a single stage. While planetary gears are great for high speed, strain-wave gears excel in precision positioning and compactness.This is also the main reason why it is suitable for robot joints
Q: Can Hansheng harmonic reducers be used in collaborative robots (cobots)?
A: Yes. Our cup-shape harmonic reducers are lightweight and offer high torque density, which is critical for the safety and efficiency required in collaborative robot joints.
Q: How do I select the right model for my application?
A: Selection depends on required output torque, input speed, and available space. Please check our specification table for Rated Torque and Max Moment details, or contact our engineering team for a custom calculation.
Additional knowledge and information-What is structure of harmonic drive?
The Harmonic Drive's simple construction, consisting of just three core elements-the Wave Generator, Flex Spline, and Circular Spline-combined with its distinctive operating principle, enables the reducer to achieve exceptionally high reduction ratios while maintaining a compact and lightweight design. This streamlined setup allows the harmonic reducer to deliver high-performance characteristics that make it an ideal choice for many precision applications.
Key performance features of this technology include zero backlash, which eliminates any play or slippage in the gears, ensuring smooth and precise movement. Additionally, the harmonic reducer offers an impressive torque-to-weight ratio, meaning it can produce a significant amount of torque relative to its lightweight and compact size. This is especially advantageous in situations where space is limited but high performance is required.
The unique operating principles of the Strain Wave Gears are what give it these superior capabilities, including its ability to deliver excellent positional accuracy. This high level of precision, combined with its small size and high reduction ratios, makes the Harmonic Drive an essential component in advanced machinery where reliability, accuracy, and performance are paramount.
Wave Generator：
The Wave Generator is a thin raced ball bearing fitted onto an elliptical hub serving as a high efficiency torque converter and generally mounted onto the input shaft.
Flex Spline：
The Flexspline is a non-rigid, thin cylindrical cup with external teeth on a slightly smaller pitch diameter than the Circular Spline. It fits over and is held in an elliptical shape by the Wave Generator.
Circular Spline：
The Circular Spline is a rigid ring with internal teeth, engaging the teeth of the Flexspline across the major axis of the Wave Generator. The Circular Spline has two more teeth than the Flexspline and is generally mounted onto the housing.
