Working principle of harmonic reducer
When the wave generator rotates continuously: force the flexible wheel continuously deform, the two teeth in the process of meshing, meshing, meshing and disengaging in changing their working state, the so-called wrong tooth movement, so as to realize the active wave generator and flexspline motion transmission.
Among them, the number of teeth of rigid wheel is slightly larger than the number of teeth of flexible wheel.The length of the wave generator is larger than diameter of the flexspline undeformed: when the wave generator is arranged inside the inner circle of the flexspline, forcing the flexspline generates elastic deformation and oval shaped, the long axis at the flexspline tooth groove insert rigid wheel, become fully engaged; and the short axis of the two wheel tooth no contact is in the disengaged state. The process of engaging or disengaging is in an out or out state.
Harmonic reducer is a kind of harmonic drive device, harmonic drive device includes Harmonic accelerator and harmonic reducer.Harmonic reducer mainly include: rigid wheel, flexible wheel and wave generator three, the three are indispensable.
