Strain wave harmonic drive gearbox applications

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.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
