NMRV series worm gearbox
adopt a pair of worm gear and worm wheel make structure more
rationalization, it not only providing better transmission
efficiency and carrying capacity, but also reduces space area in
structure position, meanwhile, at the condition of close volume, it
can get bigger transmission ratio. it can combine with all kinds of
speed reducer and speed variator, which can satisfy different using
demand. Size: NMRV*0. NMRV*0. NMRV*0.
NMRV*3. NMRV*5. NMRV*0. NMRV**0. NMRV**0. NMRV**0
Structure Features
1. Made of high-quality aluminumalloy, light in Weight and
non-rusting
2. Large in output torque
3. Smooth in running and low in noise, can work long time in
dreadful conditions
4. High in radiating efficiency
5. Good-looking in appearance, durable in service lifa end small in
volume
6. Suitable for ominbearing installation
Main Materials
1. Housing: Die-cast aluminum alloy(size ******0), cast iron(size

thickness between 0.3 and 0.5mm after precise grinding
3. Worm wheel: Wearable stannum bronze alloy
Surface painting
Aluminum alloy housing:
1. Shot blasing and special antiseptice treatment on the aluminum
alloy surface
2. After phosphating, pain with bule. Sliver, grey, red or based on
customer demands.
