Tips for using strain wave harmonic drive gearbox

When the harmonic reducer is in use if the output end is aimed horizontally downwards, the grease injected into the inner wall space of the flexspline must exceed the meshing tooth surface.
The installation plane of the rigid wheel and the rigid wheel connection and the installation plane of the flexible wheel and the flexible wheel need to be statically sealed to ensure that the grease will not leak during the use of the reducer and avoid the reducer from working with little or no oil Time damage.
During the installation process of harmonic drive, please do not knock the parts of the reducer with hard objects, or apply strong pressure to avoid damage to the parts.
If you have any questions during the inspection, please contact us.
