2-Stage NMRV Worm Gearbox 90 – 110

The 2-Stage NMRV Worm Gearbox 90 – 110 is a compact drive unit combining two worm gear stages for a very large gear ratio. The gearbox has high torque, smooth operation, and is suitable for conveyors, mixers, lifting mechanisms, and rotation systems.

The aluminum alloy or cast iron housing helps with good heat dissipation, corrosion resistance, and easy multi-directional installation. It is widely used in automation, processing, mechanical engineering, and renewable energy.

General Design of the 2-Stage NMRV Worm Gearbox 90 – 110

This 2-stage gearbox is designed to be compact, sturdy, and easy to install even in limited spaces. With the housing made of solid aluminum alloy, it helps reduce weight, provides good heat dissipation, and resists corrosion.

The worm and worm wheel system is precisely machined, ensuring smooth transmission, reduced friction, and increased lifespan. The 2-stage design is a combination of two NMRV gearboxes, namely the NMRV 90 gearbox and NMRV 110 gearbox, helping to increase torque and reduce speed effectively, suitable for systems requiring powerful operation but low output speed.

Detailed Structure of the 2-Stage NMRV Worm Gearbox 90 – 110

The 2-stage NMRV gearbox consists of the following main components:

• Worm shaft: Made of hardened alloy steel, polished to reduce friction and withstand high loads.
• Worm wheel: Made of bronze or brass, providing stable force transmission and wear resistance.
• Housing: Solid die-cast aluminum alloy, reducing weight, resisting corrosion, and providing efficient heat dissipation.
• Intermediate coupling: Connects the two stages, ensuring stable torque transmission and minimizing vibration.
• Input shaft: Directly installed with an electric motor or through a flexible coupling/flange.
• Output shaft: Hardened steel, solid or hollow type, easy to install into conveyors, mixers, or other industrial rotating mechanisms.

Applications of the 2-Stage NMRV Worm Gearbox 90 – 110

The 2-stage NMRV 90 – 110 gearbox is applied in many operations such as:

• Because the gearbox has a high ratio, it can reduce the motor speed to a low speed suitable for conveyors.
• Solar panel wiping and adjusting systems require slow, precise, and durable outdoor transmission.
• Mixers, agitators, and crushers with slow-speed, heavy-duty drives.
• Lifting mechanisms and lifting tables requiring load-holding torque and self-locking capability.

Installation Guide for the 2-Stage NMRV Gearbox

To install the 2-stage NMRV gearbox properly, follow the sequence below:

Step 1: Pre-installation Inspection

Check the gearbox model, mounting type, flange dimensions, shaft diameter, and bolt holes. Ensure the specifications match the motor and the parts are undamaged.

Step 2: Installing the Gearbox with the Motor

Place the gearbox into the installation position, aligning the input shaft and flange with the motor. Once the parts are matched, tighten the bolts evenly to secure the drive assembly.

Step 3: Checking the Installation Assembly

Recheck the shaft concentricity, bolt tightness, and contact points between the motor flange and the gearbox to ensure proper technical installation.

Step 4: Test Run

Run the system at no-load for a short time, check for noise and vibration, and observe the assembly points to ensure there is no oil leakage or abnormality.
