2-Stage NMRV Gearbox 63 – 90

2-Stage NMRV Gearbox 63 – 90 is a gearbox line specifically designed to create a very large gear ratio, helping to reduce rotational speed to a low level while maintaining strong torque, ensuring stable equipment operation, energy saving, and high durability. Thanks to the combination of two NMRV gearboxes, the product becomes a top choice in drive systems requiring high traction and low speed.

General Design of the 2-Stage NMRV Gearbox 63 – 90

The 2-stage gearbox is designed with a compact, sophisticated style while ensuring rigidity and high load capacity. The entire housing body is cast from solid aluminum alloy, lightweight yet durable, and the surface is treated with an anti-oxidation electrostatic powder coating, helping the product operate stably in dusty and high-humidity industrial environments.

The two-stage worm and gear structure is scientifically arranged to increase the gear ratio while maintaining smoothness and stability during operation. With a flexible design, the device is easily installed with an electric motor or other drive devices, suitable for various mounting directions depending on system requirements.

The structure of the 2-stage NMRV gearbox is formed by the combination of two transmission stages, the first stage being the NMRV 63 gearbox and the subsequent stage being the NMRV 90 gearbox. This connection helps create a much higher gear ratio than a single-stage gearbox, helping the device achieve strong traction and effective speed reduction.

Structure of the 2-Stage NMRV Gearbox 63 – 90

The main components of the 2-stage NMRV gearbox 63 – 90 include:

• Worm Shaft: Made of hardened alloy steel, precision machined to increase load capacity, reduce wear, and ensure stable transmission.
• Worm Gear: Usually made of copper alloy, meshing with the worm shaft to transmit torque, reduce friction, and enhance the service life of the gearbox.
• Housing: Both NMRV 63 and NMRV 90 gearboxes use die-cast aluminum alloy housings, which are lightweight, have good heat dissipation, resist corrosion, and are easy to install in various positions.Input and Output Shafts: The input shaft connects to the motor via a flange or coupling. The output shaft transmits torque to the machinery, which can be a hollow shaft or solid shaft depending on the configuration.
• Bearings and Oil Seals: Bearings help the shafts rotate stably and reduce friction during operation. Oil seals keep lubricating oil inside the gearbox and prevent dust and moisture from entering.
• Lubricating Oil: Contained inside the two gearbox stages to lubricate the worm and worm gear pair, reduce heat, and extend the service life of the transmission parts.

Technical Specifications of the 2-Stage NMRV Gearbox 63 – 90

The parameters below assist in selecting the appropriate gearbox for the motor and application requirements.

NMRV 63 Gearbox Technical Specifications

NMRV 63 is the first transmission stage, receiving power from the motor before transmitting it to the NMRV 90 stage.

NMRV 90 Gearbox Technical Specifications

NMRV 90 is the second transmission stage, continuing to reduce speed and increase torque before transmitting to the working equipment.

Applications of the 2-Stage NMRV Gearbox 63 – 90

The 2-stage NMRV gearbox 63 – 90 is widely applied in various industrial fields such as:

• Conveyor systems in manufacturing plants.
• Mixers, agitators, and packaging machines requiring high traction.
• Food, pharmaceutical, and wood processing production lines.
• Lifting systems, winding machines, and fabric cutting machines.

Installation Guide for 2-Stage NMRV Gearbox

To install the 2-stage NMRV gearbox correctly according to technical standards, follow the steps below:

Step 1: Check the Gearbox and Motor

Compare the mounting type, flange dimensions, input shaft, and bolt locations between the motor and the gearbox. Check that the components are not bent, cracked, or missing before installation.

Step 2: Install the Flange with the Motor

Place the gearbox in the correct position, aligning the flange and input shaft concentric with the motor shaft. Then tighten the bolts in order to secure the transmission assembly.

Step 3: Post-Installation Inspection

Recheck the connecting bolts, shaft concentricity, and clearance between mating surfaces to ensure the assembly meets technical requirements.

Step 4: Test Run

Run the system under no-load conditions for a short time, monitor noise, vibration, and check for oil leaks before putting it into operation.
