RCSG Cup-shaped Strain Wave Gear
Working Principle
Harmonic reduce working principle refers to the use of relative motion of the flexspline, circular spline and wave generator. The motion and power transmission is mainly achieved by using the controlled elastic deformation of the flexspline. The elliptical cams in the wave generator rotate inside the flexspline to deform the flexspline. While the teeth of the flexpline at the long end of the elliptical cam of the wave generator enter into engagement with the teeth of the circular spline, the teeth of the flexspline at the short end are disengaged from the teeth of the circular spline. For the teeth between the long and short axes of the wave generator, they are in the semi-engaged state of gradually entering engagement in different sections along the circumference of the flexspline and the circular spline, called engagement. And in the semi-engaged state of gradually exiting engagement, called engagement-out. When the wave generator rotates continuously, the flexspline continuously generates deformation, so that the teeth of the two wheels continuously change their original working state in four kinds of motion: engaging, meshing, engaging and disengaging, and generate the motion of misaligned teeth to realize the motion transmission from the active wave generator to the flexspline.
