EP-NMRV040 Mid-Range Aluminium Worm Reducer – Product Overview

Cái 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.

✓ Các tính năng và lợi ích chính

⚙ 12 Ratios + 4 Flanges = 48 Configurations
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.
⚒ Ø18 mm Output Shaft – Industry Standard
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.
❄ Continuous Duty at 40°C Ambient
Aluminium conducts heat 3x faster than cast iron. Run at 0.37 kW continuous duty without supplementary cooling fans – reducing energy cost and maintenance.
⚖ 2.3 kg – Overhead and Wall-Mount Capable
Light enough for inverted and overhead installations without structural reinforcement. Reduces installation cost and expands design flexibility on OEM machine frames.

⚙ Ứng dụng trong công nghiệp

EP-NMRV040 aluminium worm reducer agricultural conveyor and general industrial applications

⚙ Agricultural Feed and Grain Conveyors
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.
⚒ Packaging and Filling Machine Drives
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.
⚛ Small Mixer and Agitator Drives
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.
⚊ Automated Gate and Barrier Actuators
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.

⚙ Hướng dẫn lựa chọn và vị trí lắp đặt

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.

❓ Câu hỏi thường gặp

▶ What output flange options are available for the EP-NMRV040?
The NMRV040 offers four output flange types: FA and FB are standard flanges for direct machine mounting. FC and FD are extended flanges for applications requiring greater shaft projection. All bolt onto the standard output face.
▶ What is the maximum output torque of the EP-NMRV040?
At 0.55 kW input and 30:1 ratio, the NMRV040 delivers 53 Nm output torque. At the widest ratio of 100:1, torque is 38 Nm at 14 rpm output speed. Always verify service factor is adequate for your application.
▶ Can the EP-NMRV040 accept NEMA C-face motors?
Yes. The NMRV040 inch series variant accepts NEMA 56C frame motors with 0.625-inch input bore. Input shaft keyway is 0.125 x 0.875 inch. Specify the inch series when ordering for installations using NEMA motors.
▶ How does the EP-NMRV040 compare to the NMRV050?
The NMRV040 covers input power up to 0.55 kW with 53 Nm max torque in a 2.3 kg housing. The NMRV050 extends to 0.75 kW with 80 Nm max torque at 3.5 kg. Choose NMRV040 when compact size matters more than torque capacity.
▶ Is the EP-NMRV040 suitable for continuous 24/7 operation?
Yes within the rated thermal capacity. At ambient temperatures below 30 degrees C and input power below 0.37 kW, continuous operation is standard. For higher power at continuous duty, verify the thermal service factor remains above 1.0.
