In this Blog, find out the harmonic Drive or Harmonic Gearbox working with the help of its three basic elements; Wave Generator, Flex-Spline and Circular Spline. The teeth of circular spline is meshed with the teeth of flex spline and the wave generator acts as a link between the two rollers causing it to mesh with the circular spline. You will find the detailed structure of the Harmonic Gearbox in this article and how this structure helps in increasing the output torque. SMD Harmonic Gear Reducer is lighter, smaller and more efficient for complex precise operations. Reference Link - https://www.smdgearbox.com/Harmonic-Drive-Working-Principle.html
