WP series gearbox is a common type of worm gearboxes. It  has compact structure, stable transmission, low vibration and noise, large reduction ratio, wide versatility, and can be used with various mechanical equipment. It has a self-locking function under certain conditions, so the braking device can be saved for some mechanical equipment with braking requirements, and its input shaft can rotate forward and reverse. WP series worm gearboxes are widely used in the reduction and transmission of various mechanical equipment such as plastics, metallurgy, beverages, mining, lifting and transportation, chemical construction and so on.

The basic structure of WP worm gearbox is mainly composed of transmission parts worm gear and worm, shaft, bearing, housing and other accessories. The housing of Shengjie WP series worm gearbox is made of cast iron, which has strong rigidity, large bearing capacity and is not easy to deform. The worm is made of 45# high-quality steel through heat treatment, and the worm gear is made of tin bronze, which has good wear resistance, especially in load capacity. And bearings, oil seals and other accessories are all from well-known brands at home and abroad.
