2-Stage NMRV 40 – 75 Gearbox

The 2-Stage NMRV 40 - 75 gearbox is a series of gearboxes connected from two NMRV gearboxes of sizes 40 and 75, forming a powerful 2-stage drive unit that multiplies the output torque several times compared to a single-stage gearbox.

Thanks to its high reduction ratio (from 1/150 to 1/10,000), the 2-stage gearbox is considered an ideal solution for equipment requiring slow rotational speeds but strong pulling force, such as conveyors, mixers, screw conveyors, packaging machines, presses, or automation systems.

Overview of the Design of the 2-Stage NMRV 40 - 75 Gearbox

The 2-stage NMRV gearbox is designed with two perpendicular shafts, compact and refined, convenient for installation in various positions. The housing is cast from a solid aluminum alloy, which reduces weight while ensuring rigidity, good heat dissipation, and high corrosion resistance.

Inside, the worm gear set is precision machined using modern CNC technology, ensuring smooth meshing, reduced friction, and noise. This optimized design helps the 2-Stage NMRV 40 - 75 gearbox operate smoothly, stably, and durably, even when working in a continuous industrial environment.

Detailed Structure of the 2-Stage NMRV 40 - 75 Gearbox

The 2-Stage NMRV 40 - 75 gearbox is formed by connecting an NMRV 40 gearbox and an NMRV 75 gearbox via an intermediate coupling. Its main components include:

• Worm shaft: Made from hardened alloy steel, precision ground to reduce friction and increase load capacity.
• Worm wheel: Produced from brass or high-grade copper alloy, ensuring smooth and durable power transmission.
• Housing: Cast from solid aluminum, lightweight, with good heat dissipation and effective oxidation resistance.
• NMRV intermediate coupling: Used to transmit stable torque between the two reduction stages, ensuring concentricity and reducing vibration.
• Input shaft: Designed with a hollow core, it can be directly connected to an electric motor via a flange or flexible coupling.
• Output shaft: Made of high-strength steel, available in solid or hollow forms, easily installed into drive equipment such as conveyors, screw conveyors, or mixer shafts.

Specifications:

• Input shaft diameter: 11mm.
• Output shaft diameter: 28mm (hollow or solid, optional).
• Reduction ratio: 1/150 - 1/10,000.
• Flange diameter: 140mm.
• Housing material: Solid cast aluminum alloy.
• Drive mechanism: Worm gear, 2-stage transmission.
• Installation type: Various positions, easily adaptable to machine space.

Practical Applications of the 2-Stage NMRV 40 - 75 Gearbox

With its flexible design and high performance, the 2-Stage NMRV 40 - 75 gearbox is widely used in various industrial sectors such as:

• Conveyor belt systems, screw conveyors in manufacturing plants.
• Mixers, blending machines, presses, serving the food, chemical, and construction material industries.
• Packaging machines, fabric winding machines, weaving machines, CNC machines, and automation lines.
• Screening equipment, grinding machines, lifting equipment requiring high torque and slow rotational speeds.
