Compact Strain Wave Zero Backlash Harmonic Drive
![]() | 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. High Precision and Repeatability Accuracy The design ensures high precision in motion control, making harmonic drives suitable for applications that require accurate and repeatable positioning. High Efficiency Energy Efficient Harmonic drives exhibit high mechanical efficiency, typically around 80-90%, which reduces energy consumption and improves system performance. |
