The NMRV worm gear speed reducer is made of aluminum. It's often
employed with the working conditions of low power and light load.
But it features of small volume and low noise.
1. Power: 0.18-15 kw
2. Speed Ratio: 7-100
3. Output Rotational Speed: 14.5-207 rpm
4. Output Torque: 1.5-118 N.m
The shell of the NMRV worm gear speed reducer is casted with high
quality aluminum alloy, which has the features of light weight and
rust resistance. With the shell processed with shot blasting
firstly and then special anti-corrosion treatment, the worm gear
speed reducer is resistant to organic solvent such as gasoline and
After being treated with phosphating and then painted with blue or
silver-white paint, it has a beautiful and unique external
appearance. The worm of the device keeps the thickness of
carburized case of 0.3mm to 0.5mm after it being treated with
carburization, quenching and fine grinding. The turbo of the device
is made of wearable tin bronze, which can keep a service life up to
10 years under the condition of normal operation.
With the features of steady transmission and low noise, the NMRV
worm gear speed reducer can work continuously in a long period with
The users should know that don't mount the NMRV worm gear speed
reducer vertically as much as possible if the space is large
enough. Or the added lubricating oil is needed much more than
horizontally mounting the device, which may lead to heating and oil
leakage easily to the device.
