Detailed Product Description

Ultra Flat Zero Backlash Harmonic Drive


Product Description 

LHD - I series harmonic drive is the high torque capacity ultra-flat strain wave gear units.

LHD - I series harmonic drives are designed with a compact and simple layout for easy integration, helps offer a small footprint and reduced weight for space-constrained applications.

These ultra-flat harmonic gear reducers are highly suitable for use as robot end joints and customer-end reducers.

These new high-torque, zero-backlash gear units have an ultra-flat configuration and feature a large cross-roller bearing with high-moment stiffness.

Key Features 

  • Ultra-flat structure 
  • Compact and simple design
  • Small size and lightweight
  • High torque capacity and high rigidity
  • Coaxial input and output

FAQ


1. Can a harmonic drive be backdriven?

Yes the harmonic drive gear can be driven back. By the way, this happens in every typical robotic cycle hundreds of times every day: Every time when the axis is in motion and slowed down rapidly, the load inertia on the gear output side drives back the gear (in a controlled manner, determined by motor and controller).

2. What does a harmonic drive do?

Hamornic drives are used in increasing the output torque in gears used in milling, in manufacturing, and in machines that use robotic arms.

3. Do you support customizing a harmonic drive do?

Yes of course. We can customize a harmonic drive based on customer's specific requirements and drawing.

4. What's the biggest advantage of your products?

We can provide complete product series, and the qualty of our harmonic drive is stable. The most important is the highest cost-effective in China.

5. What are the main components of a harmonic drive?

The main components are the circular spline (fixed outer ring), the flexspline (flexible inner ring with fewer teeth), and the wave generator (an elliptical disc that fits inside the flexspline).
6. What applications are harmonic drives used in?
They are used in applications requiring high precision and reliability, such as robotics, aerospace, defense, medical equipment, and semiconductor manufacturing equipment.
7. How do you select a harmonic drive for a specific application?
Selection depends on factors like torque requirements, desired reduction ratio, space constraints, load capacity, and environmental conditions. It's essential to consult with manufacturers or experts to choose the appropriate model.
