Product Description


NMRV reducer is a new type of reducer, which can also be called RV reducer. The weight of NMRV reducer is relatively light. The shell is made of aluminium alloy. It has the advantages of light weight, superior strength, exquisite appearance, high heat dissipation performance, long service life, no noise and so on. It is convenient and simple to connect with the motor.

1.Made of high-quality aluminum alloy, 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 life and small in volume
6.Suitable for omnibearing installation



1.Housing:die-cast aluminum alloy(frame size:025 to 090); cast iron(frame size:110 to 130).

2.worm: 20Cr,carbonize & quencher heat treatment make the hardness of gear's surface up to 56~62 HRC, retain

carburization layer's thickness between 0.3 and 0.5mm after precise grinding

3.worm wheel: wearable stannum bronze alloy


To install the reduction unit it is necessary to note the following recommendation:

1.Check the correct direction of rotation of the reduction unit output shaft before fitting the unit to the machine.
2.Before mount with the prime mover and device, please check the reducer's every axial diameter, aperture, key and
key slot, to be sure their dimensions are not deviation, and avoid assembling too tight or too loose, unless it will influence
the reducer's performance.
3.The mounting on the machine must be stable to avoid any vibration.
4.Whenever possible, protect the reduction unit against solar radiation and bad weather.
5.In the case of particularly lengthy periods of storage(4-6 months), if the oil seal is not immersed in the lubricant
inside the unit, it is recommended to change it since the rubber could stick to the shaft or may even have lost the elasticity it
needs function properly.
6.Painting must definitely not go over rubber parts and the holes on the breather plugs if any.
7.When connect with hollow or solid shaft, please grease the joint to avoid lock or oxidation.
8.Check the correct level of the lubricant through the indicator, if there is one.
9.Starting must take place gradually, without immediately applying the maximum load.
10.Supporting unit is required when using various of reducer matched with motor directly and the weight of motor is a
little bigger than common.
11.Ensure the motor cools correctly by assuring good passage of air from the fan side.
12.In the case of ambient temperatures<-5 or>+40 call the Technical Service
