High Gear Ratios Achievable Ratios: Harmonic drives can achieve very high gear reduction ratios in a single stage, which is difficult for other types of gears. Zero Backlash Low Backlash: Harmonic drives offer extremely low to zero backlash, enhancing positioning accuracy and repeatability, which is essential in precision applications like robotics and CNC machinery. High Torque Capacity Torque Transmission: Despite their compact size, harmonic drives can transmit high torque. This is due to the large number of teeth in contact between the flexspline and the circular spline. |
