EP-NMRV-E075 Aluminium Worm Gearbox

🔗蜗杆导向尾部输出轴——关键区别因素

The defining feature of the NMRV-E075 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.

🌞 4 kW IEC Flange + High-Resolution Tail Shaft

At 4.0 kW, the NMRV-E075 accepts the full IEC 100/112 motor frame directly while simultaneously providing a tail shaft for high-resolution position feedback, covering the demanding requirements of servo-assisted heavy automation.

◯ Same Torque as Standard NMRV075

The NMRV-E075 delivers identical maximum output torque (6,603 N·m) to the standard NMRV075, 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。

🌿 Heavy Agricultural Monitoring

High-torque NMRV-E075 worm gearbox for heavy auger and elevator drives where the tail shaft mounts a rotation sensor confirming grain flow in real time and triggering an alarm if the auger jams.

💧 Mixing Tank Level-Speed Control

Worm gear reducer with tail output shaft for industrial mixing tanks where a tail-shaft encoder feeds back to a variable-frequency controller, maintaining constant tip-speed regardless of fluid viscosity.

🏗 Construction Material Monitoring

Aluminium worm gearbox with tail shaft for concrete mixer and aggregate conveyor drives where the tail-shaft tachometer provides real-time rotation monitoring to the plant SCADA system.

⚙ Servo-Assisted Automation

NMRV-E075 worm gearbox tail shaft for servo-assisted positioning stages where the tail encoder provides position feedback in semi-closed loop control, reducing servo drive cost versus full servo gearbox solutions.

★★★★★

“We installed NMRV-E075 on our heavy auger drive with a tail-shaft rotation sensor feeding our SCADA system. During harvest, we receive real-time confirmation that the auger is turning and immediate notification if it jams. Excellent peace of mind.”

Ian M. — Operations Manager, Grain Facility 🇦🇺 Australia (SA)

★★★★★

“The NMRV-E075 with tail-shaft encoder drives our concrete mixer feed conveyor. The speed feedback to our batching computer maintains accurate aggregate dosing across different mix designs. Concrete quality consistency has improved markedly.”

Tony B. — Plant Manager, Ready-Mix Concrete 🇦🇺 Australia (QLD)

★★★★☆

“We use NMRV-E075 on our chemical mixing tank agitator. The tail shaft tachogenerator monitors worm shaft speed and feeds back to our DCS. We now detect agitator stall in high-viscosity batches before the motor trips, avoiding product losses.”
