The SHD-08 model is commonly used in the elbow area of robots. what is Harmonic Drive Actuator? This precision harmonic drive actuator is composed of three main components that work together to achieve high-precision motion control and torque transmission. These three components interact in a way that produces high reduction ratios with minimal backlash, enabling the harmonic reducer to deliver precise, smooth, and efficient motion control in various applications such as robotics, aerospace, and automation systems.These components are: Circular Spline: The circular spline is a rigid internal gear that has two more teeth than the flexible gear. It typically remains fixed to the casing of the device. This component plays a crucial role in the gear reduction process by interacting with the flexspline to generate precise movement and torque transmission. Flexspline: The flexspline is a cup-shaped, thin-walled, elastic metal part with external teeth located on the outer edge of its open end. This component deforms as it rotates along with the wave generator, allowing it to mesh with the circular spline. The flexspline is typically connected to the output shaft, serving as the key element that transmits motion and torque from the wave generator to the circular spline. Wave Generator：The wave generator consists of an elliptical cam and a flexible bearing. It is usually connected to the input shaft of the system. The inner ring of the flexible bearing is mounted on the elliptical cam, while the outer ring can elastically form into an elliptical shape through the rolling motion of the balls inside the bearing.
