✅ Fitur Utama & Manfaat Unik
🔗 Poros Keluaran Ekor Arah Cacing — Pembeda Utama
The defining feature of the NRV-E063 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.
🖼 Line Shaft + Master Encoder Reference
The NRV-E063 is the preferred solution for central-line-shaft packaging facilities where each station requires chain input for drive and a tail shaft encoder for PLC synchronisation.
◯ Same Torque as Standard NRV063
The NRV-E063 delivers identical maximum output torque (5,595 N·m) to the standard NRV063, 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 Siap
Poros keluaran ekor menyediakan titik koneksi langsung untuk encoder putar, tachogenerator, dan generator pulsa yang memantau kecepatan poros cacing dalam sistem kontrol gerak loop tertutup, sehingga menghilangkan braket encoder eksternal dan perangkat keras kopling.
🚫 IP54 — Integritas Segel Ganda
Baik lubang keluaran utama maupun lubang keluar poros ekor disegel dengan segel bibir kontak ganda, mempertahankan perlindungan IP54 di semua orientasi pemasangan tanpa kebocoran oli pada antarmuka poros mana pun.

❓ Pertanyaan yang Sering Diajukan
What is the tail output shaft on the EP-NRV-E063 and how is it different from the main output?
The tail shaft on the NRV-E063 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 5,595 N·m load torque.
Does the tail shaft reduce the main output torque of the NRV-E063?
No. The tail shaft draws only the small torque needed for its connected device. The main output retains the full 5,595 N·m rating, identical to the standard NRV063.
What is the input shaft specification for the NRV-E063?
The NRV-E063 has a solid keyed input shaft (no IEC flange). The shaft diameter matches the equivalent NMRV063 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-E063 tail shaft?
Any standard keyed rotary encoder with the matching bore diameter can be mounted on the NRV-E063 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-E063.
Can the NRV-E063 be used for closed-loop speed control in a chain-driven system?
Yes. The NRV-E063 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.

★★★★★
“Eight NRV-E063 units drive our packaging hall central-line-shaft chain conveyors. The tail-shaft encoders synchronise all eight lines via our PLC. Production throughput increased 12% after synchronisation was implemented.”
Marcus L. — Maintenance Engineer, Packaging Plant 🇦🇺 Australia (NSW)
★★★★★
“We use NRV-E063 on our grain cleaning machine chain drive. The tail-shaft rotation sensor confirms grain flow and triggers an alarm if the screen stops. The system has prevented three cleaning machine jams from escalating to equipment damage.”
