✅ Temel Özellikler ve Benzersiz Avantajlar

🔗 Sonsuz Dişli Yönlü Kuyruk Çıkış Mili — Temel Farklılaştırıcı Özellik

The defining feature of the NRV-E040 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.

📈 3,118 N·m Chain Drive with Encoder

The NRV-E040 delivers 3,118 N·m from a chain or belt input while simultaneously providing a tail shaft encoder output — the complete instrumented chain-drive solution in a single gearbox.

◯ Same Torque as Standard NRV040

The NRV-E040 delivers identical maximum output torque (3,118 N·m) to the standard NRV040, 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.

🅆 Kodlayıcı ve Geri Besleme Hazır

Kuyruk çıkış mili, kapalı devre hareket kontrol sistemlerinde sonsuz dişli milinin hızını izleyen döner kodlayıcılar, takojeneratörler ve darbe üreteçleri için doğrudan bir bağlantı noktası sağlar ve harici kodlayıcı braketleri ve bağlantı donanımlarını ortadan kaldırır.

🚫 IP54 — Çift Conta Bütünlüğü

Hem ana çıkış deliği hem de kuyruk mili çıkışı, çift temaslı dudak contalarıyla kapatılarak, her iki mil arayüzünde de yağ sızıntısı olmadan tüm montaj yönlerinde IP54 koruma seviyesi korunmaktadır.

🏭 Uygulama Senaryoları

⚙ Conveyor Speed Synchronisation

NMRV-E040 worm gearbox for multi-drive conveyor synchronisation systems. The tail shaft mounts a pulse encoder that feeds back to a master PLC, allowing all conveyor sections to maintain matched belt speeds.

🚮 Packaging & Labelling with Feedback

Industrial worm gear reducer with tail output shaft for packaging line label applicators and capping heads where encoder-verified torque delivery prevents label misregistration.

🌿 Agricultural Controlled Seeding

Corrosion-resistant NMRV-E worm gearbox for precision seeding machinery where tail-shaft encoder feedback to a GPS-linked controller varies seed rate in real time across paddock zones.

📥 Textile Tension Control

Worm gearmotor with tail shaft for textile winding machine let-off drives where real-time winding speed feedback via the tail shaft encoder maintains precise fabric tension throughout the roll.

❓ Sıkça Sorulan Sorular

What is the tail output shaft on the EP-NRV-E040 and how is it different from the main output?

The tail shaft on the NRV-E040 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 3,118 N·m load torque.

Does the tail shaft reduce the main output torque of the NRV-E040?

No. The tail shaft draws only the small torque needed for its connected device. The main output retains the full 3,118 N·m rating, identical to the standard NRV040.

What is the input shaft specification for the NRV-E040?

The NRV-E040 has a solid keyed input shaft (no IEC flange). The shaft diameter matches the equivalent NMRV040 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-E040 tail shaft?

Any standard keyed rotary encoder with the matching bore diameter can be mounted on the NRV-E040 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-E040.

Can the NRV-E040 be used for closed-loop speed control in a chain-driven system?

Yes. The NRV-E040 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.

⭐ Müşteri Yorumları

★★★★★

“Our feed-mill conveyor uses NRV-E040 units chain-driven from a central shaft. The tail-shaft encoders provide each station’s speed to our supervisory controller, enabling automatic load balancing across the conveyor network.”

Wayne F. — Mill Manager, Stock Feed Producer 🇦🇺 Australia (QLD)

★★★★★

“The NRV-E040 drives our batch-feed conveyor via chain and the tail shaft mounts a tachogenerator for our SCADA integration. The combined chain-input and encoder-output design was exactly what our control engineer needed.”

Rosa K. — Engineering Manager, Food Ingredients 🇳🇿 New Zealand

★★★★☆

“We used six NRV-E040 units on our inclined conveyor chain drives. The tail-shaft pulse counters feed our warehouse management system with real-time belt motion confirmation and the self-locking at ratio 40 prevents backdriving on power loss.”

Jan P. — Maintenance Engineer, Packaging Warehouse 🇨🇿 Czech Republic
