It’s important to follow the manufacturer’s recommendations for maintenance intervals and procedures to ensure optimal performance and longevity of the NMRV gearbox. By adhering to these guidelines and addressing any issues promptly, users can expect an NMRV gearbox to provide reliable service for many years.
NMRV Gearbox Ratios
NMRV gearboxes are available in a variety of gear ratios to suit different applications and torque requirements. The gear ratio determines the relationship between the input and output speeds of the gearbox. Commonly available ratios include:
- 5:1: This ratio provides higher output torque at a slower output speed compared to the input speed.
- 7.5:1: This ratio offers a balance between torque and speed.
- 10:1: With this ratio, the output speed is further reduced while increasing torque output.
- 15:1: This ratio is suitable for applications requiring higher torque output at the expense of speed.
- 20:1: This ratio maximizes torque output while significantly reducing output speed.
- 25:1: It provides even higher torque output at a further reduced output speed.
- 30:1: This ratio is ideal for applications demanding maximum torque at minimum output speed.
- 40:1 and higher: These ratios are used in applications with very high torque requirements and low output speed.
The choice of gearbox ratio depends on the specific application, desired output speed, and required torque. It’s important to select the right ratio to ensure optimal performance and efficiency in your machinery.

- Efficient Power Transmission: The worm gear mechanism in NMRV gearboxes provides high gear reduction ratios, allowing for efficient power transmission while minimizing energy losses.
- Quiet Operation: The helical design of the worm screw and worm wheel contributes to quieter operation compared to traditional straight-cut worm gears.
- Wide Range of Ratios: NMRV gearboxes are available in various gear ratios, allowing users to select the appropriate configuration for their specific application needs.
The combination of these design principles results in an NMRV gearbox that offers efficient, reliable, and quiet power transmission for a wide range of industrial applications.
NMRV Gearbox Ratios
NMRV gearboxes are available in a variety of gear ratios to suit different applications and torque requirements. The gear ratio determines the relationship between the input and output speeds of the gearbox. Commonly available ratios include:
- 5:1: This ratio provides higher output torque at a slower output speed compared to the input speed.
- 7.5:1: This ratio offers a balance between torque and speed.
- 10:1: With this ratio, the output speed is further reduced while increasing torque output.
- 15:1: This ratio is suitable for applications requiring higher torque output at the expense of speed.
- 20:1: This ratio maximizes torque output while significantly reducing output speed.
- 25:1: It provides even higher torque output at a further reduced output speed.
- 30:1: This ratio is ideal for applications demanding maximum torque at minimum output speed.
- 40:1 and higher: These ratios are used in applications with very high torque requirements and low output speed.
The choice of gearbox ratio depends on the specific application, desired output speed, and required torque. It’s important to select the right ratio to ensure optimal performance and efficiency in your machinery.

erates based on a worm and worm wheel mechanism. Here’s how it works:
The gearbox consists of two main components: the worm (a screw-like shaft) and the worm wheel (a toothed wheel). The worm is driven by the input power source, while the worm wheel is connected to the output shaft.
As the worm rotates, its threaded shaft engages with the teeth of the worm wheel. The helical shape of the worm causes the teeth of the worm wheel to push against each other, resulting in a smooth and gradual transfer of motion. This mechanism provides the speed reduction and torque multiplication required for various applications.
One key characteristic of NMRV gearboxes is that the worm can turn the worm wheel, but the reverse is not possible due to the high friction generated by the helical threads. This feature prevents the output shaft from back-driving the input shaft, providing mechanical locking and enhancing safety and stability in applications.
The NMRV gearbox’s operation is continuous, and its simple design contributes to its reliability and efficiency. It is important to ensure proper lubrication to minimize wear and heat generation during operation.
