2-Stage NMRV Gearbox 75 – 130

The 2-Stage NMRV Gearbox 75 – 130 is a high-end gearbox designed to meet the demands of high-power, low-speed, and high-torque transmission. Featuring an independent two-stage transmission structure, this 2-stage gearbox delivers durable, stable, and energy-efficient working performance, making it suitable for modern industrial machinery systems.

Design of the 2-Stage NMRV Gearbox 75 – 130

The 2-stage NMRV gearbox is designed with a sturdy, compact, and sophisticated style, aiming for a combination of high performance and industrial aesthetics. The housing is cast as a single piece from high-grade aluminum alloy, helping to reduce weight while ensuring rigidity and excellent load-bearing capacity.

The surface of the gearbox is treated with electrostatic powder coating to prevent oxidation, limit wear, and ensure a long service life in dusty, humid, or mildly chemical environments. Intelligent cooling fins integrated into the housing help lower temperature quickly during continuous operation.

Structure of the 2-Stage NMRV Gearbox 75 – 130

Being a connection between two NMRV gearboxes, with the 1st stage being an NMRV 75 gearbox and the 2nd stage being an NMRV 130 gearbox. The two units are closely linked by an intermediate NMRV coupling, ensuring stable torque transmission and absolute concentricity:

• Worm Shaft: Made from high-quality alloy steel, hardened and surface-polished to reduce friction and increase operational durability.
• Worm Gear: Uses brass or wear-resistant bronze alloy material, ensuring smooth, stable, and accurate power transmission.
• Housing: Single-piece casting made of high-grade aluminum, with an anti-rust electrostatic powder-coated surface to enhance lifespan and aesthetics.
• Intermediate Coupling: Connects the two gearboxes, ensuring continuous transmission and reducing vibration when load changes.

Installation Guide for 2-Stage NMRV Gearbox

Proper installation procedure helps the 2-stage NMRV gearbox operate stably and ensures transmission capability.

Step 1: Pre-installation inspection

Check the external condition of the gearbox, input shaft, output shaft, flange, mounting holes, and bolts to ensure the equipment is not damaged or missing parts.

Step 2: Install the gearbox via flange

Place the gearbox flange into the correct mounting position with the motor or drive assembly. Align the concentricity between the mating surfaces and then tighten the bolts evenly in sequence to secure firmly.

Step 3: Check assembly positions

Check the tightness of the flange, the concentricity of the shaft, and all connecting bolts before powering on the system.

Step 4: Test run and inspection

Run the gearbox without load for a short time, monitor noise, vibration, and check assembly positions or oil leaks if any.
