EP-NMRV-E130 Aluminium Worm Gearbox

🔗 Worm-Direction Tail Output Shaft — The Key Differentiator

The defining feature of the NMRV-E130 is its additional tail output shaft that extends in the same direction as the worm shaft axis. This second output enables simultaneous drive of two independent loads from a single gearbox — a primary application drive via the main output bore and a secondary auxiliary drive (encoder, tachometer, small pump, or fan) via the tail shaft.

📥 11 kW IEC + Extra-Large Tail Shaft

The NMRV-E130 delivers 12,076 N·m with direct IEC 132B5 motor flange mounting plus a 45 mm tail shaft for high-resolution encoder feedback, covering the most demanding instrumented heavy-industrial drive requirements.

◯ Same Torque as Standard NMRV130

The NMRV-E130 delivers identical maximum output torque (12,076 N·m) to the standard NMRV130, confirming that the tail shaft adds zero performance penalty on the main output. The tail shaft is driven directly off the worm shaft end, not the output stage.

🅆 Encoder & Feedback Ready

The tail output shaft provides a direct connection point for rotary encoders, tachogenerators, and pulse generators that monitor worm shaft speed in closed-loop motion control systems, eliminating external encoder brackets and coupling hardware.

🚫 IP54 — Dual-Seal Integrity

Both the main output bore and the tail shaft exit are sealed with dual-contact lip seals, maintaining IP54 protection across all mounting orientations without oil weeping at either shaft interface.

🚢 Heavy Crane Hoist Monitoring

Extra-large NMRV-E130 worm gearbox for gantry crane hoist drum drives where the tail shaft provides real-time hoist speed feedback to the crane overload protection system.

📥 Port Bulk Handling SCADA

High-power worm gear reducer with tail output shaft for port grain conveyor drives where the tail shaft speed signal confirms throughput rate to the terminal management system.

🍲 Large Mining Instrumented Drive

Aluminium worm gearbox with tail shaft for large surface mining conveyor drives where the tail-mounted encoder feeds belt speed data to the mine belt management and splice monitoring system.

⚙ Large Reactor Process Control

NMRV-E130 worm gearbox for large chemical reactor agitator drives where the tail shaft encoder provides process speed feedback to the reactor control system for viscosity-controlled mixing.

★★★★★

“We use the NMRV-E130 on our gantry crane hoist drum drive. The tail-shaft encoder provides load position feedback to our crane control PLC with 5 mm positioning resolution. The integrated encoder mount saved us two weeks of custom bracket fabrication time.”

Craig S. — Crane Engineer, Heavy Industry 🇦🇺 Australia (SA)

★★★★★

“Our large primary clarifier rake uses an NMRV-E130 with a tail-shaft pulse counter integrated into our water authority SCADA. We now monitor rake rotation remotely across all eight clarifiers from a single control room screen.”

Niamh F. — Asset Manager, City Water Services 🇮🇪 Ireland

★★★★☆

“The NMRV-E130 drives our port stacker-reclaimer slewing mechanism. The tail-shaft encoder feeds our terminal management system with real-time slewing position data. Installation was straightforward and position accuracy is excellent.”
