1.Wave Generator：Consists of an elliptical cam and flexible ball bearing, which generates periodic elastic deformation to drive the flexspline. The standard cam fits continuous stable operation, while the reinforced cam adapts to frequent reversing and impact loads, ideal for robot joints with cyclic start-stop shocks.
2.Flexspline：A cup-shaped thin-wall alloy steel gear serving as the core deformable component. The thin-wall structure enables elastic gear meshing; the thickened tooth-root version enhances anti-fatigue performance for long-cycle operation.
3.Circular Spline：A rigid alloy steel ring with inner teeth and more tooth quantity than the flexspline, acting as a fixed positioning reference. Conventional alloy steel applies to general automation scenarios, and surface-quenched variants are suitable for high-torque and high-wear working conditions.

4.Reduction Ratio：Single-stage reduction ratio ranges from 50 to 160. A higher ratio delivers higher positioning precision but reduces allowable output torque. 50–80 ratio is for high-speed joint rotation, while 100–160 ratio is for ultra-precision slow positioning work.
5.Output Structure：Available in solid shaft and hollow shaft types. The hollow shaft reserves a central through-hole for wiring and pipeline layout to save assembly space, preferred for robot joints. The solid shaft is applicable for fixed precision positioning platforms.

1. Ultra‑low Backlash Performance
Realizes near‑zero gear backlash through elastic strain‑wave meshing. Helps equipment maintain repeatable accurate angle positioning and prevents positioning offset for precision‑demanding automation work.
2. High Torque‑to‑Weight Ratio
Generates large output torque with small outline dimension and light weight. Helps mechanical designers miniaturize robot joint structure and reduce moving load of motion mechanism.
3. Large Single‑stage Reduction Ratio
Achieves reduction ratio 50‑160 within one gear stage without multi‑stage gear stacking. Cuts total quantity of transmission spare parts, reduces assembly difficulty and lowers equipment failure probability.

4. Smooth Stable Operation
Elastic tooth engagement reduces meshing vibration and running noise. Ensures jitter‑free movement for optical inspection equipment and medical robots.
5. Compact Installation Dimension
Three‑in‑one integrated assembly saves installation space. Fits narrow inner cavity space of collaborative robots and semiconductor handling equipment with limited layout room.

1. Collaborative Robot Joint Drive
Used for arm and wrist joints of human‑machine collaborative robots. Near‑zero backlash and light weight satisfy repeated high‑precision arm movement. Recommend hollow‑shaft harmonic reducer, reduction ratio 100‑120.
2. Semiconductor Wafer Handling Equipment
Applied on rotary positioning unit for wafer transfer and indexing station. Low vibration and high positioning accuracy avoid scratch and displacement on fragile silicon wafers. Recommend standard flexspline version, reduction ratio 120‑160.

3.Minimally‑invasive Surgical Robot Actuation Unit
Mounted inside manipulator joints of surgical robots. Stable low‑jitter output guarantees tiny‑scale precise manipulator motion. Choose low‑vibration grade hollow‑shaft harmonic reducer.
4. Precision Optical Rotary Positioning Platform
Used for rotary indexing of optical detection and laser processing devices. Near‑zero backlash eliminates angular drift during repeated indexing. Solid‑shaft harmonic reducer is suitable for this stationary platform.
