For drives that need a robust link between shafts, the Gummi ADDF-A gear coupling uses cast steel hubs with meshing teeth. It is a double-compensating metallic coupling from Gummi's AD Line. The design allows the assembly to handle minor shaft misalignment while still transmitting torque, making it suitable for demanding industrial machinery.

The AD Line covers metallic toothed couplings built with heat-treated steel components. Within that family, the ADDF-A stands out as the cast steel, double-compensating model. Its teeth engage with clearance, so the coupling can tolerate small alignment deviations without interrupting power flow. Sizes in this series are ADDF-A 80, ADDF-A 90, ADDF-A 100, ADDF-A 110 and ADDF-A 120. Nominal torque and maximum speed for each size are listed on the individual product pages.

These couplings are typically selected for high-torque, continuous-duty applications such as conveyor belts, mills, mixers, process pumps, industrial fans and rolling equipment. They appear in food, chemical, cement and steel plants as part of a drive train between a motor and the driven machine. The double-compensating feature is useful when the two shafts are not perfectly aligned.

Selection begins with the torque the machine transmits. Apply a service factor based on the load type and operating hours, then compare that result with the nominal torque of the candidate size. Verify the maximum allowable speed and the shaft diameters as well, because the coupling must fit both shafts. During installation, align the shafts as accurately as possible and follow the manufacturer's instructions for lubrication and hub adjustment.

Maintenance centers on lubricating the teeth and routinely checking alignment and seal condition. Proper lubrication limits wear and helps the coupling perform consistently over time. If noise, vibration or lubricant loss appears, inspect the assembly before further wear develops. For a quote, provide the model or part number, the diameters of both shafts, the motor power and rpm, and the driven machine's power and rpm.
