✅ 핵심 기능 및 고유한 이점

🔗 웜 기어 방향 테일 출력 샤프트 — 핵심적인 차별점

The defining feature of the NRV-E050 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.

🅆 PTO Drive + Safety Monitoring

The NRV-E050 accepts PTO chain or belt input up to 1.1 kW while the tail shaft provides the rotation monitoring output for safety interlock systems — critical for grain dryer conveyor safety in Australian agriculture.

◯ Same Torque as Standard NRV050

The NRV-E050 delivers identical maximum output torque (4,280 N·m) to the standard NRV050, 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.

🅆 인코더 및 피드백 지원

꼬리 출력 샤프트는 폐쇄 루프 모션 제어 시스템에서 웜 샤프트 속도를 모니터링하는 회전 엔코더, 타코제너레이터 및 펄스 발생기를 직접 연결할 수 있는 지점을 제공하여 외부 엔코더 브래킷 및 커플링 하드웨어를 제거합니다.

🚫 IP54 — 이중 밀봉 무결성

주 출력부와 테일 샤프트 출구 모두 이중 접촉 립 씰로 밀봉되어 모든 장착 방향에서 IP54 보호 등급을 유지하며 샤프트 인터페이스에서 오일 누출이 발생하지 않습니다.

❓ 자주 묻는 질문

What is the tail output shaft on the EP-NRV-E050 and how is it different from the main output?

The tail shaft on the NRV-E050 exits the housing in the worm-direction axis (opposite end of the worm shaft), while the main output bore is perpendicular (90 degrees) to the worm axis. The tail shaft is driven off the worm shaft end and is used for encoder mounting, tachometer connection, or light auxiliary drive, while the main output delivers the full 4,280 N·m load torque.

Does the tail shaft reduce the main output torque of the NRV-E050?

No. The tail shaft draws only the small torque needed for its connected device. The main output retains the full 4,280 N·m rating, identical to the standard NRV050.

What is the input shaft specification for the NRV-E050?

The NRV-E050 has a solid keyed input shaft (no IEC flange). The shaft diameter matches the equivalent NMRV050 bore input diameter. It accepts chain sprockets, belt pulleys, and rigid couplings. A bilateral (double-ended) input shaft is standard; single-end configuration available on request.

What encoder types can be mounted on the NRV-E050 tail shaft?

Any standard keyed rotary encoder with the matching bore diameter can be mounted on the NRV-E050 tail shaft: incremental (5V–24V, 100–10,000 PPR), SSI absolute, or resolver-type. Confirm the encoder bore size and keyway before ordering. The tail shaft key dimensions match the catalogue DZ shaft specification for NMRV-E050.

Can the NRV-E050 be used for closed-loop speed control in a chain-driven system?

Yes. The NRV-E050 is the ideal solution for chain-driven systems requiring closed-loop speed feedback. The chain drives the solid input shaft; the main output drives the load; and the tail shaft mounts an encoder that feeds speed/position data back to the controller. This eliminates the need for a separate encoder mounting bracket or a second independent encoder drive arrangement.

⭐ 고객 리뷰

★★★★★

“Our grain-dryer fan conveyor uses NRV-E050 chain-driven from the dryer main shaft. The tail-shaft encoder confirms rotation to our dryer management PLC and automatically shuts down the burner if the conveyor stops. A safety-critical feature that works perfectly.”

Peter N. — Farm Operations Manager 🇦🇺 Australia (QLD)

★★★★★

“We chain-drive NRV-E050 units on our food-plant batch conveyors. The tail-shaft tachometer signal integrates with our HACCP batch tracking system, recording conveyor speed for every production run. Exactly the audit trail we needed.”

Thomas W. — Plant Engineer, Food Manufacturer 🇬🇧 UK

★★★★☆

“The NRV-E050 drives our irrigation pump chain drive and the tail shaft monitors pump rotation for our SCADA. We now get automatic alerts if the pump stops during an irrigation cycle. The combined chain-input encoder-output design simplified our installation considerably.”

Helen M. — Farm Manager, Horticulture 🇦🇺 Australia (WA)
