Small Size High Precision Harmonic DriveProduct Description The model 8 and model 11 harmonic drive of LS and LH series are known as the mini-shaped strain wave reducer. LS And LH series miniature strain wave reducers provide high positioning accuracy in a very compact package. These mini strain wave gears harmonic drive are well suited for semiconductor and robotics applications, especially end of arm axes for small industrial and collaborative robots, industrial machinery where weight is a critical factor. How it Works The Flexspline is slightly smaller in diameter and has two fewer teeth than the Circular Spline. The elliptical shape of the Wave Generator causes the teeth of the Flexspline to engage the Circular Spline at two opposite regions across the major axis of the ellipse. For every 180 degree clockwise rotation of the Wave Generator the Flexspline teeth are advanced counterclockwise by one tooth in relation to the Circular Spline. Each complete clockwise rotation of the Wave Generator results in the Flexspline moving counter-clockwise by two teeth from its original position relative to the Circular Spline. Key Features

FAQ 1. What is a harmonic drive box? A harmonic drive box is a type of gear system that produces high reduction ratios in a compact size. It uses the mechanics of a flexible element deforming to transmit motion and achieve high precision and torque. 2. How does a harmonic gear box work? A harmonic gear box works by using a circular spline, flexspline, and a wave generator. The wave generator deforms the flexspline into an elliptical shape, which then engages with the teeth of the circular spline at two points, providing a high reduction ratio through the difference in tooth count between the engaged elements. 3. 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). 4. 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. 5. 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. 6. 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. |
