The inside of the green harmonic reducer bearing harmonic is what meaning?

To make clear the inside of the green harmonic reducer bearing harmonic is what meaning? Must first understand the structure of harmonic reducer, and the principle of harmonic drive, so you know the title of source of harmonic reducer. Star yu river lake for your explanation: harmonic reducer reducer can be divided into harmonic reducer and RV reducer. Harmonic reducer is a kind of harmonic drive installation, harmonic drive installation including harmonic accelerator harmonic wave. Harmonic reducer mainly includes: first round, round, soft and wave attack three landscapes themselves. Harmonic drive is usually composed of three fundamental components, including a first round of internal tooth, a job can produce radial elastic deformation and soft round with outer teeth and a installed inside the soft round, oval, with flexible rolling bearing outer ring wave attack. Outside of the soft wheel gear teeth within less than just round. Harmonic drive is to apply the elastic deformation of a building can be controlled to complete the transfer of a mechanical movement. Among them, just the number of teeth on the wheel slightly larger than the number of teeth on the wheel. Wave of attacks on turns, corresponding with the long axis direction of soft wheel tooth just complete meshes into just the inner gear wheel; In the short axis, the teeth in the full release. When the first round of fixed, wave attack attack turns, soft round of gritting teeth will, in turn, meshes into and out of the first round of internal tooth, soft tooth ring of arbitrary point on the radial displacement will show similar to sine wave of change, so the drive called harmonic drive. Harmonic reducer internal structure when the wave of attacks when loaded soft round circle, the wave length ratio of attack without deformation of the soft wheel in large diameter, forcing produce elastic deformation and soft round oval shaped, make its long axis in the soft wheel tooth inserted just wheel tooth groove, become a complete meshing state; And its short axis two rounds of tooth full contact, not in the off state. By the meshing between the release process is in the recess action or meshes into state. Working principle of the machine of decelerate of harmonic wave of attacks when wave attack implement continuous rotation: force soft wheel deformation from time to time, make the two wheel tooth in stop meshes into, meshing, tooth out, in the process of release from time to time change their working state, the so-called wrong tooth movement, thus complete the active wave attack, and the soft wheel movement.
