2-Stage NMRV Gear Motor 75 – 130

The 2-Stage NMRV Gear Motor 75-130 is a gear motor combined from an electric motor, specifically a 3-phase electric motor, with a gearbox, specifically a 2-stage gearbox. The product is manufactured from high-quality die-cast aluminum alloy and solid cast iron to provide excellent corrosion and oxidation resistance. It ensures fast heat dissipation and stable operation in heavy-duty environments to maintain high performance during continuous work.

Overview of 2-Stage NMRV Gear Motor 75-130

Electric Motor

• Material: Die-cast aluminum housing or lightweight gray cast iron housing, integrated terminal box with rubber gasket sealed against dust and water reaching IP55 standards.
• Characteristics: Synchronous power is calculated at a moderate level to optimize torque efficiency, low no-load current, and low heat generation to protect the first-stage gear train.

Gearbox

• Function: Combines the primary NMRV 75 unit with the mid-size secondary NMRV 130 unit. The system deflects the transmission direction by a 90-degree angle, reducing rotational speed to an ultra-slow level through multiplied double gear ratios.
• Characteristics: The NMRV 75 housing is made of compact extruded aluminum alloy; the NMRV 130 housing is made of reinforced cast iron with good torsional stress resistance, saving more space than the 150 series. The mechanism features high mechanical self-locking capabilities when stopped.

Structure of 2-Stage NMRV Gear Motor 75-130

The 2-Stage NMRV Gear Motor 75-130 is assembled from electric motors of various powers (such as 3-phase electric motor 1.1kW 1.5Hp, 3-phase electric motor 1.5kW 2Hp) combined with a 2-stage NMRV gearbox

Structure of the electric motor:

• Stator (stationary part): Consists of a steel core and winding coils, generating a magnetic field when energized.
• Rotor (rotating part): Located inside the stator, receiving force from the magnetic field to rotate.
• Cooling fan: Cools down the motor while running.
• Bearings: Support the rotating shaft and reduce friction.

Structure of the NMRV gearbox:

• 1st Stage: The NMRV 75 gearbox has a housing made of die-cast aluminum alloy, with multiple stiffening ribs on the surface to keep it lightweight yet durable.
• 2nd Stage: The NMRV 130 gearbox is the highest-load stage, so its housing is made of thick cast iron or aluminum alloy, featuring support ribs running along the body to prevent deformation under high torque transmission.

Specifications of 2-Stage NMRV Gear Motor 75-130

The 2-Stage NMRV Gear Motor 75-130 is a transmission device composed of two connected NMRV gearboxes in series, creating a large gear ratio and significantly reducing the output speed. With a worm gear design, the product operates smoothly, has low vibration, and well meets high-torque transmission requirements.

Specifications of 3-Phase Electric Motor 1.5kW 2Hp

The 3-phase electric motor 1.5kW 2Hp is designed to high standards, ensuring continuous and stable operation in various working conditions. The flange-mounted style makes connecting to the transmission system quick and convenient.

Specifications of NMRV 75 Gearbox

The NMRV 75 gearbox acts as the first reduction stage, helping to reduce the initial rotational speed and stably transmit power to the next reduction stage.

Specifications of NMRV 130 Gearbox

The NMRV 130 gearbox is the second reduction stage, significantly increasing output torque, suitable for systems requiring low speed and high pulling force.

Applications of 2-Stage NMRV Gear Motor 75-130

The 2-Stage NMRV Gear Motor 75-130 has many outstanding advantages and is widely applied in various industries such as:

• Heavy-duty conveyors – industrial conveyor lines
• Agitator and mixer systems: High-capacity mixing machines
• Coiling, pulling, and material rolling systems
• Crushing systems: Low-speed crushers and rollers
• Feeding systems – presses – load pulling machines
• Lifting systems: Slow-speed lifting equipment
• Woodworking machines, fabric cutting machines, mechanical processing machines

Instructions for Assembling Electric Motor with 2 NMRV Gearboxes

• Step 1: Connect the electric motor to the first gearbox and secure it tightly with screws.
• Step 2: Insert the intermediate coupling shaft into the output shaft hole of the first gearbox.
• Step 3: Push the input shaft of the second gearbox so that it smoothly engages with the intermediate coupling shaft.
• Step 4: Tighten the connecting bolts between the two gearboxes firmly to prevent looseness.

Note: Align the shafts straight, clean away all dirt, and evenly tighten all perimeter bolts.
