HARMONIC DRIVE

High accuracy: a significant proportion of its teeth are in mesh at all times, and are engaged in two zones 180 degrees apart. This means that the effects of tooth pitch errors and accumulated pitch errors on rotational accuracy are neutralised, ensuring high positional and rotational accuracy. High reduction ratio: A harmonic gearbox offers high single-stage reduction ratios ranging from 1:30 to 1:500. Three basic components arranged along the same axis, without complex structures, can achieve these high reduction ratios. High torque capacity: although each tooth is subjected to a negligible amount of force, it provides a high torque capacity due to the manner in which the teeth come into contact with one another and because a significant proportion of the teeth in the flexspline are engaged at all times. Compact and lightweight: whilst being smaller in size and lighter in weight than conventional gearing mechanisms, the harmonic gearbox delivers the same levels of torque and speed reduction ratios as its conventional counterparts, enabling machinery and equipment to be made smaller and lighter.
