Problems solved by technology
The transmission disc needs to rotate relative to the installation housing, so there must be a rotation gap between the transmission disc and the installation housing; fine powder particles will enter the harmonic reducer through the rotation gap, thereby affecting the transmission efficiency of the harmonic reducer ; Moreover, the existence of fine powder particles is also easy to cause loss to the service life of the harmonic reducer
