2-Stage NMRV Gearbox 40 – 50

The 2-Stage NMRV Gearbox 40-50 is a gearbox line combined by two NMRV gearboxes, designed to be compact, operate smoothly, with high efficiency and a high gear ratio, effectively reducing speed and increasing torque in industrial transmission systems.

General design of the 2-Stage NMRV Gearbox 40-50

This 2-stage gearbox is designed with a compact, modern style and high aesthetics, suitable for many industrial transmission applications.

The housing is made of solid aluminum alloy, helping to reduce weight while ensuring durability and good heat dissipation during operation.

Structure of the 2-Stage NMRV Gearbox 40-50

The 2-stage NMRV gearbox is structured by combining an NMRV 40 gearbox and an NMRV 50 gearbox, to create a larger gear ratio compared to a single-stage gearbox. This structure helps strongly reduce output speed while increasing torque. In terms of structure, the 2-stage NMRV gearbox includes:

• Worm gear: Usually made of bronze or brass alloy to increase wear resistance
• Worm shaft: Made of hardened, polished steel to reduce friction and improve working lifespan.
• Gearbox housing: Cast from high-grade aluminum alloy, with light weight, good heat dissipation and effective corrosion resistance, suitable for harsh working environments.
• NMRV intermediate coupling set: Connects the output shaft of the NMRV 40 unit to the input shaft of the NMRV 50 unit, helping to transmit torque stably, concentrically and limit vibration during operation.
• Gearbox input shaft: Usually designed to connect directly with an electric motor via a flange or flexible coupling.
• Gearbox output shaft: Made of hard steel, solid or hollow type, easily installed into transmission devices such as conveyors, agitators, or lifting systems.

Technical specifications of the 2-Stage NMRV Gearbox 40-50

To select the right model suitable for the transmission system, users should refer to the specifications of each gearbox stage below.

NMRV 40 Gearbox

NMRV 40 is the first reduction stage, receiving power directly from the motor and transmitting it to NMRV 50.

Technical specifications

NMRV 50 Gearbox

NMRV 50 performs the second reduction stage, creating a lower output speed and greater torque before transmitting to the equipment.

Practical applications of the 2-Stage NMRV Gearbox 40-50

This 2-stage NMRV gearbox 40 – 50 is commonly applied in many industries such as:

• Applied in conveyor systems, agitators, mixers.
• In the face mask manufacturing industry, fabric rolling machines.
• In conveyor systems and cargo conveyors that require slow and heavy movement.

Installation guide for 2-stage NMRV gearbox

To install the 2-stage NMRV gearbox correctly according to technical standards, the following sequence must be followed to ensure that the assembly between the motor and the gearbox meets requirements.

Step 1: Check installation specifications

Compare the model, gear ratio, mounting type, flange dimensions, shaft diameter, and bolt positions of the gearbox with the motor. At the same time, check external details to ensure no damage before installation.

Step 2: Install the gearbox onto the motor

Insert the motor shaft into the input shaft of the gearbox, align the two flanges to contact evenly, and then tighten the bolts position by position to secure the transmission assembly.

Step 3: Post-assembly inspection

Check the concentricity between the motor and the gearbox, the tightness of all bolts and contact surfaces. Ensure that the assembly is not eccentric or misaligned.

Step 4: System test run

Operate the motor at no load for a short time to check noise, vibration, and oil leakage at the connection points before putting it into use. Besides this article, you can refer to
