2-Stage NMRV 50-75 Gearbox

The 2-Stage NMRV 50-75 Gearbox is a type of gearbox capable of large speed reduction and high output torque generation. The two-stage design provides smooth transmission, stable performance, and a compact size. The housing of the 2-stage gearbox is made of aluminum alloy or cast iron, offering good heat dissipation and durability in industrial environments. Commonly used in conveyors, packaging machines, and automation systems requiring low speed and high torque.

General design of the 2-Stage NMRV 50-75 Gearbox

The 2-stage NMRV gearbox is composed of two NMRV gearboxes, which are the NMRV 50 gearbox and the NMRV 75 gearbox, featuring a right-angle, compact design that is easy to install in various positions.

The housing is made of monolithic die-cast aluminum alloy, featuring lightweight, fast heat dissipation, and corrosion resistance, helping the device operate efficiently even in continuous industrial environments.

The 2-Stage NMRV 50-75 Gearbox is precision-machined with a smooth surface to reduce friction, limit noise, and increase transmission efficiency. This design ensures smooth operation, long service life, and low wear.

Internal structure of the 2-Stage NMRV 50-75 Gearbox

The 2-Stage NMRV 50-75 Gearbox is formed by connecting the output shaft of the NMRV 50 to the input shaft of the NMRV 75 via an intermediate coupling, ensuring stable and concentric force transmission. Basic components include:

• Worm screw: Made of hardened alloy steel with a polished surface to reduce friction and increase durability.
• Worm gear: Made of high-grade copper alloy, ensuring smooth force transmission and good wear resistance.
• Housing: Monolithic die-cast aluminum, lightweight, durable, corrosion-resistant, and provides good heat dissipation.
• Intermediate coupling: Connects the two reduction stages, ensuring continuous power transmission and limiting vibration.
• Input shaft: Directly installed with the electric motor via a flange or flexible coupling.
• Output shaft: High-strength steel, solid or hollow type, easily connected to equipment such as conveyors, agitators, screw conveyors.

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 installation parameters

Compare the model, ratio, mounting type, flange dimensions, shaft diameter, and bolt hole locations between the motor and the gearbox. Check the components to ensure they are undamaged before installation.

Step 2: Install the gearbox with the motor

Insert the motor shaft into the input shaft of the gearbox, aligning the flange so that the two contact surfaces are in the correct position. Then, evenly tighten the bolts to secure the drive assembly.

Step 3: Check the drive assembly

Check the coaxiality of the shaft, the tightness of all bolts, and the contact points between the motor and the gearbox. Ensure all parts are installed correctly before operation.

Step 4: Test run inspection

Run the system without load for a short time, monitor noise and vibration, and check the installation positions to ensure there are no oil leaks or abnormalities.
