Commitment to genuine quality – Long-term 24-month warranty – Fast doorstep delivery – Full CO/CQ documentation.
The 2-Stage NMRV Worm Gearbox 75 – 110 is a combination of two gearboxes, providing smooth power transmission, high efficiency, and suitability for various industrial applications such as conveyors, agitators, mixers, and lifting equipment.
The 2-stage worm gearbox is designed to be compact, robust, and modern, suitable for installation in restricted spaces. With a solid cast aluminum alloy housing, it is lightweight yet durable, offers fast heat dissipation, resists corrosion, and performs well in harsh industrial environments.
The worm shaft and worm wheel system are precision-machined to ensure smooth transmission, reduced friction, and extended service life. The two-stage mechanism combines two NMRV gearboxes, specifically the NMRV 75 gearbox and the NMRV 110 gearbox, to create a large gear ratio, increase torque, and effectively reduce output speed.
The 2-stage NMRV worm gearbox consists of the following main components:
The specifications below help select the appropriate gearbox for the motor and operating conditions of the system.
The NMRV 75 handles the first reduction stage, receiving motion from the motor and transmitting power to the NMRV 110 gearbox.

The 2-stage NMRV worm gearbox 75 – 110 is widely used in:
To install the 2-stage NMRV worm gearbox, follow these steps:
Step 1: Check the equipment
Verify the model, gear ratio, mounting type, flange dimensions, and shaft diameter of the gearbox against the motor. Check the housing body, shaft, and bolts to ensure the equipment meets the installation conditions.
Step 2: Install the gearbox onto the motor
Insert the motor shaft into the input shaft of the gearbox, align the two contact flanges evenly, and tighten the bolts in sequence to secure the assembly.
Step 3: Post-installation inspection
Check the concentricity between the motor and gearbox, bolt tightness, and joint positions to ensure the drive assembly is properly installed.
Step 4: Test run before operation
Run the system under no-load conditions for a short time, monitor vibration and noise, and check connection points to ensure normal equipment operation.
