Réducteurs à vis sans fin WPA/Réducteurs à vis sans fin
A WPA worm gear reducer, also known as a worm gearbox, is a compact mechanical power transmission device designed to reduce rotational speed while increasing torque. It consists of a worm (a screw-like gear) meshing with a worm wheel (a toothed gear) at a 90-degree angle, enabling efficient power transfer between non-intersecting shafts. WPA worm gearboxes are widely used in industries like metallurgy, mining, and packaging for applications such as conveyor drives and lifting systems.
