EP-NMRV040 Mid-Range Aluminium Worm Reducer – Product Overview
그만큼 EP-NMRV040 occupies the critical mid-point of the NMRV aluminium worm reducer range – large enough for real conveyor and machinery loads, yet compact enough at 2.3 kg to remain practical for wall-mount, overhead, and space-constrained installations. With 12 standard ratios from 5:1 to 100:1 and input power acceptance up to 0.55 kW, the NMRV040 handles applications that the smaller NMRV025 and NMRV030 cannot reach – belt conveyors running at moderate speeds, packaging machine fold-and-seal mechanisms, agricultural feed dispensers, and small mixer drives. The Ø18 mm output shaft is the most common shaft size in small industrial drive systems, accepting standard couplings, sprocket hubs, and timing pulleys directly. Four output flange options – FA, FB, FC, and FD – provide direct machine mounting flexibility that eliminates the separate gearbox mounting bracket from the BOM. The NMRV040 also serves as the output stage for NMRV025/040 and NMRV030/040 double-stage combinations, and as a pre-stage for NMRV075 and NMRV090 in extreme-ratio configurations reaching 5000:1.

✓ 주요 특징 및 장점
One housing design covers the vast majority of light-medium industrial drive requirements. Ratio or flange changes on existing installations need only a gearbox swap – no frame modifications.
The most commonly used shaft size in small industrial drives. Standard sprockets, timing pulleys, and coupling hubs fit directly without custom machining or adaptor sleeves.
Aluminium conducts heat 3x faster than cast iron. Run at 0.37 kW continuous duty without supplementary cooling fans – reducing energy cost and maintenance.
Light enough for inverted and overhead installations without structural reinforcement. Reduces installation cost and expands design flexibility on OEM machine frames.
⚙ 산업 분야 응용
The NMRV040 is the standard drive for small grain augers, feed conveyors, and agricultural sorting tables across Australian farms. The aluminium housing handles outdoor exposure, fertiliser dust, and humidity without the corrosion issues of unprotected cast iron.
Mid-range torque for carton folding, film wrapping, and filling line conveyor drives. FA output flange mounts directly to machine frames. IEC 71B14 motor connection standardises the motor-reducer package.
NMRV040 at 80:1 to 100:1 drives small batch mixers, paint stirrers, and chemical dosing agitators. The compact aluminium housing fits inside mixer frame enclosures.
Slow-speed drives for automated car park barriers, industrial gate actuators, and access control mechanisms. 100:1 ratio delivers the controlled slow motion these applications require.
⚙ 선택 가이드 및 장착 위치
Select the NMRV040 when your application requires output torque between 11 Nm and 53 Nm at input power up to 0.55 kW. For torques above 53 Nm, step up to the NMRV050 at 80 Nm maximum. For torques below 11 Nm, the lighter NMRV030 at 24 Nm maximum may be more cost-effective.

⚖ Aluminium vs Cast Iron Comparison
For light-to-medium industrial applications, aluminium worm reducers offer significant advantages over traditional cast iron – particularly in the Australian market where corrosion resistance and shipping weight are major cost factors.
