Product Description
NMRV-VS Dual Input Worm Gearbox with IEC Motor Flange
Product Description
- Quick stop function
For a general gear reducer, it takes 5 to 10 seconds for the stop time, but for the NRV series, the stop state could be reached in only 2 to 5 seconds. - High safety
The NRV worm gearbox adopts a different way compared with the traditional 1 in that it doesn’t need the sprocket and pulley. What’s more, the transmission structure is not exposed so that injuries to the operator could be reduced. - Good protection
Grade IP55 is adopted which has good isolation for dust and moisture. - Excellent thermal conductivity
The NRV worm gear is equipped with cooling CHINAMFG so that the body has excellent thermal conductivity and low temperature-rising. - Long service life
The worm gearbox operates smoothly with low noise which is suitable for long-term contact work in harsh environments.

Using NMRV Gearboxes in High-Load Applications
NMRV gearboxes can be used in moderate to high-load applications, but their load capacity is generally limited compared to some other gearbox types. They are best suited for applications with light to moderate loads, such as conveyor systems, packaging equipment, and small machinery. It’s important to consider the specific load requirements and consult with gearbox manufacturers or engineers to ensure the chosen NMRV gearbox can handle the intended application’s load demands.
Lubrication for an NMRV Gearbox
Lubrication is essential for the proper functioning and longevity of an NMRV gearbox. The type and amount of lubricant required may vary depending on the gearbox model and manufacturer. Here are the general lubrication practices:
- Recommended Lubricants: Use the lubricants specified by the gearbox manufacturer. Typically, high-quality gear oils with the appropriate viscosity and additives are recommended.
- Initial Fill: Prior to the gearbox’s first operation, ensure that it is properly filled with the recommended lubricant to the correct level. Follow the manufacturer’s guidelines for the proper quantity.
- Lubricant Change: Regularly change the lubricant according to the manufacturer’s recommended intervals. Over time, lubricants can degrade due to heat and contamination, which can affect gearbox performance.
- Temperature Considerations: Gearboxes operating in extreme temperatures may require lubricants with specific temperature ranges to ensure proper viscosity and protection.
- Checking Levels: Periodically check the lubricant level in the gearbox to ensure it is within the specified range. This can prevent damage caused by insufficient lubrication.
- Oil Analysis: Some gearbox systems benefit from regular oil analysis to monitor lubricant condition and identify potential issues before they cause significant damage.
Proper lubrication practices contribute to reduced friction, wear, and heat generation within the NMRV gearbox, leading to improved efficiency and extended lifespan.
Working Principle of an NMRV Gearbox
An NMRV gearbox, also known as a worm gear reducer, operates 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.
