2-Stage NMRV Gearbox 75 – 150

The 2-Stage NMRV Gearbox 75 – 150 is a gearbox line formed by two NMRV gearboxes connected in series. As a result, the 2-stage gearbox can achieve deep speed reduction and strong pulling force, making it ideal for industrial machinery such as conveyors, presses, mixers, or automation equipment requiring continuous operation.

Overview Design of the 2-Stage NMRV Gearbox 75 – 150

This 2-stage NMRV gearbox series is designed with a modern style, sturdy structure, and high finish, ensuring both durability and aesthetics. The housing is cast as a single piece from high-grade aluminum alloy, helping to reduce weight while maintaining rigidity, good heat dissipation, and high corrosion resistance.

Inside, the worm and worm gear assembly is precisely machined using CNC technology, ensuring smooth transmission, reduced noise and friction, and enhanced working efficiency. As a result, the device operates stably for a long time, suitable for harsh working environments such as workshops, heavy-duty conveyors, or continuous production lines.

Structure of the 2-Stage NMRV Gearbox 75 – 150

The 2-Stage NMRV Gearbox 75 – 150 has a detailed structure including:

• Worm gear: Made of high-quality copper alloy or brass, offering good wear resistance and ensuring smooth, stable power transmission.
• Worm shaft: Machined from hardened alloy steel, with a polished surface to reduce friction and increase operating lifespan.
• Housing: Made of die-cast aluminum, featuring lightweight, fast heat dissipation, and oxidation resistance, suitable for harsh environments.
• Intermediate coupling: Connects the two transmission stages, ensuring smooth torque transmission and reducing vibration during operation.
• Input shaft: Directly connects to the electric motor through a flange or flexible coupling.
• Output shaft: Made of high-strength hardened steel, available in solid or hollow forms, allowing easy connection to drive equipment such as conveyors, screw conveyors, or rotating mechanisms.

Technical Specifications of the 2-Stage NMRV Gearbox 75 – 150

The 2-Stage NMRV Gearbox 75 – 150 is assembled from two worm gearboxes, namely NMRV 75 and NMRV 150. Each stage handles a reduction phase, helping to create a large gear ratio and high torque.

NMRV 75 Gearbox

The NMRV 75 gearbox is the first transmission stage, responsible for reducing speed from the motor before transmitting it to the NMRV 150 stage.

Installation Guide for 2-Stage NMRV Gearbox

To properly install the 2-stage NMRV gearbox, follow these steps:

Step 1: Inspect the equipment

Inspect the gearbox body, input shaft, output shaft, flange, and bolt holes. Ensure all components are complete and free of damage prior to installation.

Step 2: Connect the flange to the motor

Bring the gearbox flange into position to mount with the motor. Align the shaft and flange concentrically, then tighten the bolts to secure the assembly.

Step 3: Post-installation inspection

Check all bolts, shaft concentricity, and contact points between the motor and the gearbox before powering on.

Step 4: Trial operation

Run the system with no load, check vibration, noise, and observe joining points to detect oil leaks or abnormal signs.
