گیربکس حلزونی NMRV075 – کاهنده دنده حلزونی آلومینیومی

⚙ Three NEMA Input Standards

Accepts NEMA 56C (0.625 in), 140TC (0.875 in), and 180TC (1.125 in) input flanges. This covers AC motors from 0.37 kW up to 2.2 kW in a single housing size — the widest motor compatibility range available in the NMRV compact series.

🔥 750 Nm Continuous Torque at 9 kg

Delivering 83 Nm/kg specific torque, the NMRV075 matches the output of typical 20–25 kg cast iron reducers in this torque class. For Australian mining and agricultural OEMs, this translates to lower shipping costs and simpler installation — especially in remote site applications accessed via light vehicles.

📈 6,603 N Output Radial Load

The highest radial load rating in the compact NMRV range (NMRV025–075). Supports direct chain sprocket mounting for 1-inch pitch roller chain — common in grain handling and aggregate conveyor systems across regional Australia — without an intermediate bearing housing.

🌞 All-Orientation Lubrication Design

Strategically positioned fill, drain, and breather ports allow correct oil level maintenance in all four primary mounting orientations. In agricultural equipment that is regularly repositioned between seasons, this flexibility eliminates the need for oil drain and refill between orientation changes.

💧 Double-Lip Seal — IP54 Standard

Double-lip NBR shaft seals on both input and output shafts prevent oil egress and dust ingress — important for grain dust environments in Australian agricultural applications and for dusty belt-conveyor headhouse environments in quarrying operations.

Mining Ancillary Equipment

Rotary screen drives, transfer conveyor tail-end drives, and dewatering screw drives — high radial load capacity withstands the vibration and impact loads of quarrying environments.

🌾

Large Agricultural Machinery

Combine harvester auger drives, silage cutter drive heads, and round baler pickup drives — three NEMA input flange options accommodate the range of PTO-connected motors used in modern farm equipment.

🏛

Water Infrastructure

Slow-speed irrigation pump actuators, weir gate drives, and sluice gate operators — the NMRV075’s self-locking characteristic at high ratios secures gate position without brakes when power is removed.

💧

Heavy Conveyor Systems

Loaded inclined belt conveyors in grain terminals, bulk material ports, and recycling facilities — 750 Nm handles starting torque peaks in fully loaded belt systems.

★★★★★

“Installed EP-NMRV075 on our grain terminal belt conveyor drives in Port Hedland. Three NEMA input flange options matched our existing motor inventory. Eighteen months of heavy-duty operation without a single issue.”

Brett Saunders 🇦🇺 — Operations Manager, Grain Terminal, Australia

★★★★★

“Replaced heavy cast iron reducers on rotary screen drives with EP-NMRV075 units. Weight reduction made the screen structure lighter and easier to service. Output torque fully meets our specification.”

Jakub Novák 🇨🇿 — Plant Engineer, Aggregate Processing, Czech Republic

★★★★½

“Using NMRV075 for irrigation weir gate actuators. Self-locking at 60:1 holds the gate perfectly without brakes. The aluminum housing resists our harsh desert environment well.”

🔌

آداپتورهای موتور IEC B5/B14

IEC 90–112 frame adaptors for three-phase motors 0.75–2.2 kW, including brake motors and high-efficiency IE3 motors.

🔨

NRV075 Torque Arm

K1=200 mm heavy-duty steel torque arm for shaft-mount NRV075 configuration — rated for the high reaction torques encountered in conveyor and agricultural applications.

🔃

Output Flanges (FA, FB)

FA and FB variants with pilot diameters 100–130 mm for direct bolted attachment to conveyor drive pulleys, pump flanges, and agricultural drive hubs.

🔒

پوشش محافظ ورودی

Heavy-duty polypropylene cover for outdoor and agricultural installations — resists UV, grain dust, and chemical spray environments common in Australian farming and quarrying.
