Overview

Harmonic Gearbox is a precision transmission device that utilizes flexible component deformation to achieve power transfer, delivering high reduction ratios through the interaction of wave generator, flex spline, and circular spline.

Key Features:
Employs flexible meshing principle for zero-backlash, high-precision transmission.
Delivers high torque capacity while maintaining compact, lightweight design.
Provides smooth operation with low noise, ideal for precision positioning and robotic joint applications.

As a leading transmission solution provider, MOFLON's harmonic gearboxes incorporate patented wave generator technology and optimized tooth profile design, ensuring exceptional transmission accuracy and extended service life for demanding applications.

Harmonic Gearbox FAQs

How does a harmonic gearbox work?

The wave generator deforms the flex spline, causing its teeth to engage progressively with the circular spline. This controlled elastic deformation enables precise speed reduction and motion transmission.
What are the main advantages?

High precision: Near-zero backlash.
Compact design: High torque-to-weight ratio.
High reduction ratios: Single-stage ratios up to 160:1.
Smooth operation: Low vibration and noise.
Where are harmonic gearboxes commonly used?

Industrial robots (articulated joints).
Aerospace systems (solar array drives.)
Medical equipment (surgical robots).
Precision manufacturing (optical positioning stages).
How to select a suitable harmonic gearbox?

Required reduction ratio and torque capacity.
Mounting configuration and space constraints.
Backlash and positioning accuracy requirements.
Environmental conditions (temperature, cleanliness).
What is the typical service life?

Standard models: 7,000-10,000 hours.
High-performance models: Up to 15,000 hours.
(Life varies with load conditions and maintenance)
Does MOFLON provide custom solutions?

Yes. MOFLON offers:
Custom flange configurations.
Modified shaft designs.
Special materials for extreme environments.
Integrated motor-gearbox assemblies.
What maintenance is required?

Regular lubrication (3,000-5,000 hour intervals).
Periodic inspection for wear or damage.
Clean regreasing for high-precision applications.
