These gearboxes are widely used in robotics for precise rotational motion, simulating joints. They are also capable of transmitting high torque with great accuracy, making them suitable for aerospace, medical, industrial automation, and military applications.
Harmonic drive consists of three main components:
-
Wave Generator: A ring bearing with a flange connected to the motor. The Wave Generator typically integrates into the Flex-spline on one side and interfaces with the motor via flange and bolts on the other side.
-
Flex-spline: A flexible ring with external teeth, positioned between the Wave Generator and the output ring (Circular Spline). The teeth of the Flex-spline engage at two contact points with the internal teeth of the Circular Spline.
-
Circular Spline: A ring with internal teeth that rotates the output shaft.
This design ensures precise and efficient transmission of motion, critical for demanding applications across various industries.
