✅ 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-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.

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。

❓ 常见问题解答

What is the tail output shaft on the EP-NMRV-E130 and what is it used for?

The tail output shaft on the NMRV-E130 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-E130?

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 12,076 N·m, identical to the standard NMRV130.

What encoder types are compatible with the NMRV-E130 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-E130?

The NMRV-E130 accepts the following IEC input flanges: 90B5, 90B14, 100/112B5, 100/112B14, 132B5. This covers the standard motor frame range for the 11 kW power class. Servo and stepper motor adaptor plates available on request.

Can the NMRV-E130 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

★★★★★

“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
