2-Stage NMRV Gearbox 50 – 90

The 2-Stage NMRV Gearbox 50 – 90 is a gearbox designed to achieve a high gear ratio and large torque. This 2-Stage Gearbox features a cast aluminum alloy (or cast iron depending on the type) housing with a compact structure to help save installation space.

The equipment operates smoothly with low noise, stable transmission capability, and good load-bearing capacity in industrial environments. Highly suitable for applications such as conveyors, packaging machines, and automation systems requiring low output speed but strong torque.

General design of the 2-Stage NMRV Gearbox 50 – 90

The 2-Stage NMRV Gearbox features a compact and easy-to-install design, suitable for various industrial spaces. With its solid cast aluminum alloy housing that is both lightweight and durable, it provides fast heat dissipation, corrosion resistance, and good impact resistance, ensuring continuous operation without performance reduction.

The internal worm and worm gear assembly is precisely machined to ensure smooth contact, reduced friction, and lower noise, helping the equipment operate smoothly and extending its lifespan.

Structure of the 2-Stage NMRV Gearbox 50 – 90

Each component in the gearbox is manufactured with high precision, contributing to enhanced transmission efficiency and durability of the equipment.

• Worm shaft: Hardened alloy steel, smooth surface, reduces friction and increases durability.
• Worm gear: Copper or brass alloy, smooth transmission, wear-resistant and high load capacity.
• Housing: Solid cast aluminum, lightweight, corrosion-resistant, good heat dissipation.
• Intermediate coupling: Connects the two reduction stages, ensuring stable torque and reducing vibration.
• Input shaft: Connects directly to the electric motor to form a gear motor, installed via a flange or flexible coupling.
• Output shaft: High-strength steel, solid or hollow type, easily connected to conveyors, mixers, screw conveyors, or lifting mechanisms.

Installation guide for the 2-Stage NMRV gearbox

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

Step 1: Pre-installation inspection

Check the model, gear ratio, mounting type, flange, input shaft, and bolt holes of the gearbox. Compare with the motor specifications to ensure compatibility for assembly.

Step 2: Connecting the gearbox to the motor

Insert the motor shaft into the shaft hole of the gearbox, align the flange so that the two contact surfaces meet evenly. Then tighten the bolts in sequence to secure the assembly.

Step 3: Checking connection points

Check the tightness of the bolts, the concentricity between the motor shaft and the input shaft of the gearbox, and ensure that the mating surfaces are not misaligned or open.

Step 4: Test running the equipment

Operate the motor in no-load mode for a short time, monitor vibration and noise, and check connection points to ensure the system operates normally.
