In the chemical industry, production equipment is often subject to corrosion, heavy dust, heavy oil contamination, heavy loads and high‑intensity continuous operation. Therefore, transmission equipment is required to deliver high performance in terms of stability, sealing, durability and safety.

JIUWEI NMRV series worm gear reducer features a compact structure, right‑angle transmission, self‑locking function, low noise and high stability. It is particularly suitable for various general‑purpose and non‑standard transmission equipment, such as chemical mixers, conveyors, dust collectors and three‑waste treatment equipment.

 

Core Advantages of JIUWEI NMRV Series Worm Gear Reducer

1. Compact structure with diverse models

Available sizes include NMRV025, NMRV030, NMRV040, NMRV050, NMRV063, NMRV075, NMRV090, NMRV110, NMRV130 and NMRV150. Models below NMRV090 adopt high‑quality aluminum‑alloy cast housing, featuring small size and light weight. For complex, highly corrosive working conditions, we can also supply housings cast from premium stainless steel. In addition, various accessories such as output shafts and output flanges in different specifications are optional, to fully adapt to equipment that cannot operate due to limited installation space.

2. Worm gear drive with low noise and low vibration

JIUWEI NMRV series reducer uses high‑quality Tin & Copper alloy for the key worm‑wheel components. The meshing tooth surfaces of the worm and worm‑wheel are precision ground, supported by high‑precision bearings. This ensures smooth operation with low noise and minimal vibration. It maintains quiet and reliable performance even under continuous heavy‑load working conditions.

3. Cost‑effective and easy‑to‑maintain

Compared with conventional multi‑stage gear transmissions, the NMRV series adopts a single‑set worm‑gear mechanism with a simple and compact structure. Regular oil change is generally all that is required for maintenance. The lubricating oil shall be VG220 or higher‑grade oil according to local climatic temperature and working‑condition requirements. The NMRV series reducer is equipped with oil holes on multiple surfaces, enabling convenient oil replacement regardless of the mounting orientation.
