The ADDF-A coupling is a double-compensating gear-type metallic coupling, made of cast steel, part of Gummi's AD Line, an Argentine coupling manufacturer. It transmits torque between shafts and accommodates misalignment, so it is used in demanding industrial drives. MR Accesorios Industriales sells it as an official distributor of Gummi in Buenos Aires, Argentina.

Gummi's AD Line brings together metallic toothed couplings with heat-treated steel components. The ADDF-A is the cast steel, double-compensating variant: the teeth mesh and allow some play between hubs, so the assembly accommodates small misalignments without losing transmission. The designation is read with the line letters and the size: ADDF-A 80, ADDF-A 90, ADDF-A 100, ADDF-A 110 and ADDF-A 120 are the sizes in this series. Each product page shows the nominal torque and maximum speed of each one.

This type of coupling is chosen to join shafts in machines with high torque and continuous movement: conveyor belts, mills, mixers, process pumps, industrial fans and rolling equipment. In Argentine industry it appears in food, chemical, cement and steel plants, always as part of a drive between a motor and the driven machine. The double compensating design helps when the alignment between both shafts is not perfect.

To select the model, start from the torque the machine transmits and apply a service factor according to the type of load and working hours; then compare that value with the nominal torque of the size. Also check the maximum allowable speed and the shaft diameters, because the coupling must fit both. During assembly, align the shafts as precisely as possible and follow the manufacturer's instructions for lubrication and hub adjustment.

Maintenance of the ADDF-A focuses on lubricating the teeth and periodically checking alignment and the condition of the seals. Correct lubrication reduces wear and maintains the coupling's performance over time. If you notice noise, vibration or loss of lubricant, it is best to inspect the assembly before wear progresses. To request a quote, send us the model or part number, the diameter of both shafts, the power and the rpm of the motor and the driven machine.
