NMRV worm gearbox is a new type of reducer, which can also be called an RV worm gearbox. “NMRV” is a general term, which refers to aluminum case worm gearbox, which has been used to be called “NMRV worm gearbox” internationally. The main components include an oil seal, oil plug, worm gearbox, ball bearing, output shaft, worm gear, worm, output shaft, motor connecting plate (flange), output shaft cover, hexagon socket head screw, double round key, gasket, etc.

NMRV series worm gear reducers have single flange input, and some have flange output or dual shaft output. The worm gear reducer could be matched with other gearboxes to reach a large ratio and torque. What’s more, due to the small size of the gearbox, it is easy to install and maintain. The NMRV worm gearboxes are manufactured with international technical requirements and possess a high technological content that guarantees high rigidity and high torque.

NMRV/NRV Series Worm Gearbox Features:

● The weight of the NMRV worm gearbox is relatively light. The shell is made of aluminum alloy. It has the advantages of being lightweight, having superior strength, exquisite appearance, high heat dissipation performance, long service life, no noise, and so on. It is easy to connect with the motor.

● NMRV worm gearbox is a more practical transmission equipment, and in appearance, design, and integration, it isis more in line with the needs of the public than other types of reducers.

●The application field and popularity of the RV worm gear reducer made of aluminum alloy are even better than other reducers. It is a kind of reducer with high practicability and a combination of advanced technology at home and abroad.

● NMRV worm gear reducer is very convenient to connect with ordinary motor, CVT, flange electromagnetic clutch brake unit, and does not need coupling. Suitable for all-around installation, the output torque is relatively large, works smoothly, and so on.

NMRV/NRV Series Worm Gearbox Application:
