SMD SRV Series Cycloidal Gearbox: Engineered for Ultimate Torque and Accuracy

The SRV Series uses a special disc that moves in a circular path, powered by an off-center shaft. As the disc turns, it works with fixed pins inside the gearbox to slow down and smooth out the motion. This design gives strong turning power and precise control, while also handling sudden heavy loads without any problems.

The speed reduction ratio in a cycloidal gearbox depends on the number of teeth on the cycloidal disc and the number of fixed ring pins. Typically, the disc has one fewer lobe than the number of pins, which makes manufacturing and assembly challenging and demands high precision
