A planetary gear reducer is a precision industrial transmission device that achieves speed reduction and torque amplification through a multi-stage gear meshing structure. Its core working principle relies on the coordinated movement of four main components: the sun gear, planetary gears, internal gear ring, and planetary carrier.
It is widely used in industrial automation, heavy machinery, new energy, and other fields, and is a core component of systems requiring reliable speed reduction and torque amplification.
