✅ 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-E110 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.
🚢 Crane-Grade IEC Flange + Position Encoder
At 7.5 kW with IEC 132B5 flange compatibility, the NMRV-E110 is purpose-built for instrumented crane travel drives where both direct motor mounting and precise position feedback are required simultaneously.
◯ Same Torque as Standard NMRV110
The NMRV-E110 delivers identical maximum output torque (9,232 N·m) to the standard NMRV110, 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
🚢 Crane Travel Feedback
Large-frame NMRV-E110 worm gearbox for overhead crane long-travel drives where the tail shaft encoder provides position feedback to the crane control system, enabling precise load positioning.
⚙ Chemical Reactor Remote Monitoring
High-torque worm gear reducer with tail output shaft for large chemical reactor agitators where the tail shaft tachometer feeds into the plant DCS for real-time agitator speed verification.
🍲 Heavy Mining Instrumented Drives
Aluminium worm gearbox with tail shaft for underground mine face-conveyor drives where the tail-mounted rotation sensor provides safety interlock signals to the mine-wide emergency stop system.
💧 Municipal Water SCADA Integration
NMRV-E110 worm gearbox for large-diameter sludge thickener drives where the tail shaft speed signal integrates directly into the water authority SCADA system for remote performance monitoring.

❓ 常见问题解答
What is the tail output shaft on the EP-NMRV-E110 and what is it used for?
The tail output shaft on the NMRV-E110 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-E110?
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 9,232 N·m, identical to the standard NMRV110.
What encoder types are compatible with the NMRV-E110 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-E110?
The NMRV-E110 accepts the following IEC input flanges: 90B5, 90B14, 100/112B5, 100/112B14, 132B5. This covers the standard motor frame range for the 7.5 kW power class. Servo and stepper motor adaptor plates available on request.
Can the NMRV-E110 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
★★★★★
“Our NMRV-E110 crane travel drives include tail-shaft encoders that feed our crane position management system. Load positioning accuracy has improved from plus/minus 50 mm to plus/minus 8 mm since installation. Excellent product for precision crane control.”
Richard H. — Crane Engineer, Manufacturing Facility 🇦🇺 Australia (VIC)
★★★★★
“We installed the NMRV-E110 on our large chemical reactor agitator. The tail-shaft encoder feeds our DCS with real-time agitator speed data. We detected a partial gear wear event early via speed drift monitoring and replaced the unit before failure.”
Dr. Klaus W. — Chemical Process Engineer 🇩🇪 Germany
★★★★☆
“NMRV-E110 drives our port conveyor with tail-shaft speed feedback to the terminal management system. Throughput monitoring is now automated and we eliminated the manual rotation checks that previously required a site walk every two hours.”
