Low Backlash Strain Wave Reducer Harmonic Gears
Product description
A harmonic drive is backlash-free with a high-ratio of speed reduction by design. This is advantageous for systems that require precise gear positioning.
Harmonic drives are integral to applications that demand high precision, high torque, and compact design. Their unique working principle and advantages make them suitable for a wide range of industries, from robotics and aerospace to medical devices and industrial automation. By providing precise and reliable motion control, harmonic drives contribute significantly to the performance and efficiency of modern technological systems.
 | Operation When the wave generator rotates, it deforms the flexspline, causing its external teeth to engage with the internal teeth of the circular spline at two opposite points. As the wave generator continues to rotate, the engagement points move around the circumference, causing the flexspline to rotate. The flexspline has fewer teeth than the circular spline, so one complete rotation of the wave generator results in the flexspline rotating by the difference in the number of teeth between the two splines, achieving a high reduction ratio. |
