Detailed Explanation of the Working Principle and Maintenance Techniques of Inkjet Printer Couplings

Inkjet printer couplings compensate for the relative misalignment between two shafts and transmit torque through the elastic deformation of a diaphragm. During maintenance, first check the diaphragm for wear or deformation, and replace it if necessary. Regular lubrication of the bearings is also required; lithium-based grease is recommended. When installing the coupling, ensure that the coaxiality error of the two shafts does not exceed 0.1mm. Furthermore, the permissible speed range of inkjet printer couplings is generally between 3000-6000 rpm; overspeeding should be avoided to ensure equipment stability.
