The working principle of a harmonic drive reducer
It utilizes the elastic deformation of the flexible spline and the meshing motion of the gear teeth. Specifically, the wave generator deforms the flexible spline, and the outer teeth of the flexible spline sequentially engage with the inner teeth of the rigid spline to achieve speed reduction.
The core components of a harmonic drive reducer
Rigid Spline (Circular Spline):
A rigid gear with an internal gear ring. It has slightly more teeth than the flexible spline; the common tooth difference is 2 teeth, which is key to achieving a high reduction ratio. The rigid spline is made of high-hardness alloy steel to ensure that its shape and precision remain unchanged during long-term meshing.
Flexible Spline (Flexspline):
A flexible gear with an external gear ring. Its wall thickness is typically only 1-2 millimeters. It is made of special alloy steel through heat treatment and precision machining, requiring both sufficient elasticity to produce controllable deformation and high strength to withstand repeated stress cycles.
Wave Generator:
This is the key component that generates controllable elastic deformation waves. The most common wave generator is an elliptical cam. When the wave generator is inserted into the inner bore of the flexible spline, it causes the flexible spline to undergo regular elastic deformation, enabling meshing and motion transmission between the gears.
