2-Stage NMRV 50 – 63 Gearbox

The 2-Stage NMRV 50 – 63 Gearbox is a gearbox series formed by combining two NMRV gearboxes, creating a transmission assembly capable of extremely high speed reduction and exceptional torque increase.

Thanks to this special design, the 2-stage gearbox well meets the transmission requirements in industrial systems that require low rotational speed, strong pulling force, and stable, energy-efficient operation. With a large transmission ratio (ranging from 1/150 to 1/10,000), this gearbox series is an ideal choice for applications demanding high precision and durable operation over a long period.

Overall Design of the 2-Stage NMRV 50 – 63 Gearbox

The 2-stage NMRV gearbox possesses a compact design, high aesthetic appeal, and easy installation in various spaces. The housing is made of solid cast aluminum alloy, which is durable, lightweight, and has good heat dissipation, ensuring stable operation even under continuous working conditions.

Inside, the worm and worm gear transmission is manufactured with high precision, and the contact surface is finely treated to reduce friction, limit noise, and increase transmission efficiency. As a result, the gearbox operates smoothly, has a long service life, and minimizes wear during use.

Internal Structure of the 2-Stage NMRV 50 – 63 Gearbox

The 2-stage NMRV 50 – 63 gearbox consists of the combination of the output shaft of the NMRV 50 gearbox and the input shaft of the NMRV 63 gearbox via a coupling, which increases the speed reduction stages while ensuring concentricity and stability. The basic structure includes:

• Worm shaft: Machined from hardened alloy steel, with a polished surface to help reduce friction and increase durability.
• Worm gear: Made of bronze or brass alloy, offering high durability, good wear resistance, and smooth transmission.
• Housing: Solid cast from high-grade aluminum, lightweight, durable, corrosion-resistant, and provides fast heat dissipation.
• Intermediate coupling: Helps connect the output shaft of the NMRV 40 to the input shaft of the NMRV 50, ensuring continuous, stable power transmission and reducing vibration.
• Input shaft: Used to connect directly with the electric motor via a flange or flexible coupling.
• Output shaft: Made of solid or hollow hardened steel, suitable for various mechanical connection types such as conveyors, mixers, or lifting mechanisms.

Specifications of the 2-Stage NMRV 50 – 63 Gearbox

To select the correct model suitable for the motor and equipment used, users need to refer to the parameters of each gearbox stage below.

NMRV 50 Gearbox

The NMRV 50 acts as the first reduction stage, receiving power from the motor before transmitting it to the NMRV 63.

Practical Applications of the 2-Stage NMRV 50 – 63 Gearbox

Thanks to its sturdy structure and flexible speed reduction capability, the 2-stage NMRV 50 – 63 gearbox is widely applied in various industries such as:

• Industrial conveyor systems, packaging lines, and cargo transportation lines.
• Agitators, mixers, and grinders in food production, chemical manufacturing, or construction materials.
• Face mask production lines, fabric rolling machines, and industrial textile machinery.

Installation Guide for 2-Stage NMRV Gearbox

To install the 2-stage NMRV gearbox properly, the following steps must be carried out sequentially to ensure that the transmission assembly is installed accurately and operates stably.

Step 1: Check parameters before installation

Verify the model, transmission ratio, mounting type, flange dimensions, shaft diameter, and bolt holes of the gearbox. Compare them with the motor specifications to ensure that both devices can be assembled together.

Step 2: Connect the gearbox to the motor

Place the gearbox in the installation position, align the input shaft straight with the motor shaft, and bring the two flanges tightly together. Then, tighten the bolts at each position to secure the transmission assembly.

Step 3: Inspect the assembled assembly

Check the concentricity of the shafts, the tightness of the bolts, and the contact surface between the motor and the gearbox. Ensure that all components are correctly positioned with no abnormal gaps.

Step 4: Check after powering on

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