RV Series Worm Gearbox - Shengjie Reducer

RV series gearbox is a widely used worm gearbox, also named NMRV worm gearbox. It draws on advanced technology at home and abroad, and owns a unique and novel square box-shaped outer structure with beautiful appearance. It is made of high-quality aluminum alloy die-casting with anti-corrosion treatment. RV worm gearbox has a series of advantages such as small size, light weight, large speed ratio range, low noise, good sealing, smooth transmission and long service life. RV gearbox is suitable for all-round installation and can be connected with various motors (single-phase motor, three-phase motor, stepper motor, servo motor, etc.). Its application field and popularity are better than other types of reducers, and it is widely used in metallurgy, mining, transportation, water conservancy, chemical industry, food, beverage, textile, tobacco, packaging, environmental protection and many other industries and fields.

The main components of RV gearbox are box body, worm gear and worm, bearing, oil seal, output shaft, motor connecting flange, etc. Sizes 25-90 of Shengjie RV gearbox are made of high-quality aluminum alloy die-casting, and sizes 110-150 are made of cast iron. The worm wheel is made of tin bronze and the inner core is made of ductile cast iron, which has a large bearing capacity and good wear resistance. The worm is made of 20Cr steel and undergoes carburizing and quenching heat treatment. The shaft is made of 45# high-quality steel also with heat treatment. The input forms of RV series worm gearbox have IEC standardized motor flange, solid shaft input, worm shaft tail extension input, output forms have hollow shaft with output flange, key hollow shaft output, plug-in solid shaft output, which can be easily combined with other mechanical combination.
