LHS Strain Wave Gears

Core features of LHS series reducers
1. High load capacity and high torque density:

Core advantages: By strengthening the rigid wheel/flex wheel tooth design, optimizing the bearing structure (such as using cross roller bearings) and high-strength materials, the rated/peak torque load capacity is significantly improved.

Applicable scenarios: Replace traditional RV reducers to meet the needs of high-load and high-inertia joints such as the base (J1), arm (J2), and shoulder (J3) of industrial robots.

2. Ultra-high rigidity (torsional stiffness & radial stiffness):

The structural reinforcement design makes it deform very little when subjected to heavy loads and impact loads, ensuring fast dynamic response and stable positioning of the system.

It is crucial to the overall accuracy of the robot (especially the repeatability) and the ability to resist external interference.

3. High precision and zero backlash:

Inheriting the inherent advantages of harmonic drive, maintaining an ultra-low backlash of ≤1 arc-min (some models can reach <0.1 arc-min) and excellent transmission accuracy.

Ensures precise motion control under heavy loads, suitable for tasks such as precision assembly, welding, and handling.

4. High reliability & long life:

Enhanced anti-fatigue design: Optimize the stress distribution of the flexible wheel for high-load conditions and improve anti-fatigue performance.

Industrial-grade sealing and lubrication: Adopt high-performance grease and multiple sealing structures, dustproof and waterproof (IP65 grade is common), adapt to harsh industrial environments.

Long design life: It can usually reach more than 7000-15000 hours under rated load, significantly reducing maintenance costs.

5. High power density:

With similar dimensions, LHS can transmit much greater torque than traditional harmonic reducers, especially suitable for scenarios with limited space but high torque output.

6. Good heat dissipation:

For high-power applications, the heat dissipation path is optimized (such as shell design), and some models support forced air cooling/water cooling interface to prevent overheating.

7. Wide selection of reduction ratios:

Provide common reduction ratios such as 50:1, 80:1, 100:1, 120:1 to meet the speed ratio and torque requirements of different joints.
