Worm geared motors series NMRV

The company "Zetek" presents a new product - worm reducers and gearmotors of RV/NMRV series. The worm geared motors of NMRV series are characterized by a size and gear ratio. Manufactured gearmotors sizes have the values from 25 to 130 (characteristic by center distance). Gear ratios have the value from 7.5 to 100 (characteristic by the ratio between angular velocity of the worm and worm wheel).


Worm geared motors of NMRV series


Сharacteristics

Worm geared motors of NMRV series position themselves as a new generation of gears made with the use of leading world technologies based on WJ series.

Advantages of the gearmotors:

● Made of high quality aluminum alloy, stainless and light.
● High torque.
● Smooth and quiet work of the mechanism.
● Taxing on a critical conditions for the work of gear mechanisms.
● High productivity in conditions of considerable excess of the background radiation.
● Compact and neat appearance, long service life.
● Suitable for installation of the bearing radio beacons.

The materials used in the making of gearmotors:
● Housing is made with the use of injection molding technology. Material: Aluminum alloy (dimensions: 025 to 090) or iron alloy (dimensions: 110 to 130).
● Due to the fact that the worm was heat treated by the carbon and chromium, the surface hardness of the gear unit has increased to 56-62 HRC, keeping the layer thickness of cementation - 0.3-0.5mm (after the careful polishing).
● Worm wheel is covered with the bronze and tin alloy.

Surface painting

Aluminium alloy housing:
● Surface passes through the shot blasting and a special antiseptic treatment.
● After phosphating it's painted with the blue (RAL5010) or silver (RAL9010). Cast iron housing is painted with the red antirust paint, then it's painted with the blue (RAL5010) or silver (RAL9010).
