Product Introduction:
Harmonic Gear Reducers consist of a fixed internal gear, a flexible gear, and a wave generator that causes radial deformation of the flexible gear. Harmonic Gear Reducers are a new type of transmission structure among gear reducers. They utilize the controllable elastic deformation wave generated by the flexible gear to cause relative tooth misalignment between the teeth of the rigid and flexible gears, thereby transmitting power and motion. This transmission method differs fundamentally from ordinary gear transmission, possessing unique characteristics in meshing theory, set calculations, and structural design. Harmonic gear reducers offer advantages such as high precision and high load-bearing capacity. Compared to ordinary reducers, they use 50% less material, reducing their volume and weight by at least one-third.
Core Features:
Small and lightweight; High transmission precision; Large transmission ratio; Simple and compact structure, easy installation; High load-bearing capacity, capable of transmitting motion to confined spaces; High transmission efficiency, smooth operation.
Product Characteristics:
High dynamic precision and accurate control: Multi-tooth meshing achieves error averaging, resulting in small transmission errors and enabling zero or low backlash meshing. Reverse transmission has no idle stroke, providing outstanding positioning accuracy.
Wide transmission ratio range and strong adaptability: Single-stage transmission ratios can reach 30~320, and double-stage transmission ratios can reach thousands, meeting different speed requirements without complex transmission chains.
High load-bearing capacity and high reliability: The tooth surfaces are in surface contact, resulting in uniform force distribution. The flexible wheel is made of high-strength materials, ensuring high load-bearing capacity.
Compact structure and lightweight design: Composed of only three core components—a rigid wheel, a flexible wheel, and a wave generator—it is small in size and light in weight, facilitating installation in confined spaces.
Smooth transmission and high efficiency: Gradual entry and exit meshing of the gear teeth eliminates impact, resulting in low operating noise and vibration.
Unique functional characteristics and wide applicability: Coaxial design of input and output shafts facilitates easy installation and provides strong transmission stability.

The QDY-CDUH Harmonic Gear Reducers are precision transmission components developed for modern intelligent automation systems. They are designed to meet the increasing demand for accurate motion control in industries such as robotics, CNC machining, semiconductor manufacturing, new energy production, and automated assembly.
Unlike traditional gear reducers that mainly depend on rigid gear transmission, harmonic gear reducers use flexible deformation technology. This unique structure allows multiple teeth to engage simultaneously, improving transmission accuracy while reducing mechanical clearance.
The QDY-CDUH series provides excellent performance in applications where installation space is limited but high precision movement is required. The compact structure allows engineers to design smaller equipment while maintaining strong transmission capability.
The main components of QDY-CDUH Harmonic Gear Reducers include:
Wave Generator: The input component that creates controlled deformation of the flex spline and transfers movement.
Flex Spline: A flexible gear component that changes shape during operation and enables precise motion transmission.
Circular Spline: A rigid gear component that works with the flex spline to achieve speed reduction.
Through the cooperation of these three core components, QDY-CDUH Harmonic Gear Reducers achieve high precision transmission, low backlash performance, stable torque output, and reliable operation.
For industrial robots and precision automation equipment, even small transmission errors may influence final product quality. Therefore, selecting a reliable harmonic gear reducer is important for improving equipment accuracy and production stability.

Source: Technical characteristics are based on harmonic transmission principles and Qiandeyi Transmission Technology product development experience.
The working principle of QDY-CDUH Harmonic Gear Reducers is based on harmonic transmission technology. Instead of relying only on rigid gear rotation, the system uses controlled elastic deformation to achieve precise speed reduction and power transmission.
When the motor drives the wave generator, the wave generator changes the shape of the flex spline. This creates continuous engagement between the flex spline and circular spline, generating the required reduction effect.
Because the flex spline and circular spline have different numbers of teeth, the reducer can achieve a high reduction ratio while maintaining a compact structure.
This transmission method provides excellent advantages including high accuracy, low backlash, smooth operation, and stable torque output, making QDY-CDUH Harmonic Gear Reducers suitable for precision motion control systems.
The special structure of QDY-CDUH Harmonic Gear Reducers allows multiple teeth to engage at the same time during operation. This improves load distribution and helps the reducer maintain stable performance under different working conditions.
Compared with many traditional transmission solutions, harmonic transmission technology provides higher precision within a smaller structure. This makes it especially suitable for robotic joints, precision positioning platforms, and compact automation systems.
