✅ 核心功能和独特优势

🔗蜗杆导向尾部输出轴——关键区别因素

The defining feature of the NMRV-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 with IEC Flange + Encoder

The NMRV-E040 delivers 3,118 N·m maximum output torque with direct IEC motor flange mounting AND a tail shaft encoder output, providing the complete gearmotor-plus-encoder function in a single compact unit.

◯ Same Torque as Standard NMRV040

The NMRV-E040 delivers identical maximum output torque (3,118 N·m) to the standard NMRV040, 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.

编码器和反馈就绪

尾部输出轴为旋转编码器、测速发电机和脉冲发生器提供了直接连接点,这些设备用于在闭环运动控制系统中监测蜗杆轴的速度,从而无需外部编码器支架和联轴器硬件。

🚫 IP54 — 双重密封完整性

主输出孔和尾轴出口均采用双接触唇形密封件密封,在所有安装方向上均保持 IP54 防护等级,且在任何轴接口处均无漏油现象。

🏭 应用场景

⚙ 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.

❓ 常见问题解答

What is the tail output shaft on the EP-NMRV-E040 and what is it used for?

The tail output shaft on the NMRV-E040 is a secondary shaft extending in the worm-direction axis (co-axial with the worm shaft, opposite end). It is used to mount rotary encoders, tachogenerators, or pulse generators for speed/position feedback, or to drive a small auxiliary load such as a lubrication pump, cooling fan, or pilot valve simultaneously with the main output drive.

Does the tail shaft affect the main output torque of the NMRV-E040?

No. The tail shaft is driven directly off the worm shaft end and carries only the small torque required for the encoder or auxiliary device. The main output bore delivers the full rated 3,118 N·m, identical to the standard NMRV040.

What encoder types are compatible with the NMRV-E040 tail output shaft?

尾轴为标准键槽轴,可安装任何孔径匹配的增量式或绝对式旋转编码器。常用选项包括 5–24V 增量式编码器(100–10,000 PPR)、SSI 绝对式编码器和旋转变压器式反馈装置。订购前,请与编码器供应商确认编码器孔径和键槽尺寸。

Which IEC motor flanges are available for the EP-NMRV-E040?

The NMRV-E040 accepts the following IEC input flanges: 56B5, 63B14, 71B5, 71B14. This covers the standard motor frame range for the 0.55 kW power class. Servo and stepper motor adaptor plates available on request.

Can the NMRV-E040 tail shaft be used to drive a secondary load simultaneously?

是的,前提是尾轴上的辅助负载扭矩不超过蜗杆轴的附加扭矩容量。对于轻型辅助负载,例如小型润滑泵(低于 0.05 kW)或先导阀,尾轴可以同时使用,不会影响主输出性能。对于高于 0.05 kW 的辅助负载,请咨询我们的工程团队。

⭐ 用户评价

★★★★★

“The NMRV-E040 drives our multi-section conveyor synchronisation system. The tail shaft encoder provides the PLC with speed reference for all eight conveyor sections and registration errors have dropped to near zero since installation.”

Marcus L. — Automation Engineer, Packaging Plant 🇦🇺 Australia (Victoria)

★★★★★

“We use the NMRV-E040 on our textile winding tension control system. The tail-shaft tachogenerator gives us real-time winding speed data and our fabric defect rate has fallen by 22% since switching from open-loop drives.”

Elif T. — Production Manager, Textile Manufacturer 🇹🇷 Turkey

★★★★☆

“Fitted NMRV-E040 units on our labelling machine indexing drives. The tail shaft encoder confirmed our line speed to within 0.1% and eliminated occasional label skip errors that had plagued the previous open-loop arrangement.”

James O. — Line Engineer, Label Manufacturer 🇦🇺 Australia (QLD)
