Riduttori a vite senza fine WPS/Riduttore a vite senza fine
WPS worm gear reducers, also known as worm gearboxes, are mechanical devices designed to reduce speed and increase torque in power transmission systems. They feature a worm (a screw-like gear) meshing with a worm wheel, creating a compact, efficient system for high-ratio speed reduction. The WPS model worm reducer gearbox, distinct from the similar WPA model, has its input shaft positioned above the output shaft, while the WPA has the input shaft below. Both models share identical foot installation and shaft dimensions for the same frame size, ensuring interchangeability.
