Speed ratio range	A single frame has 12 reduction ratios from 5:1 to 100:1

Product Features:
• Housing Construction:
○ For frames 025–105, the housing is made from lightweight and rust-resistant aluminum alloy, ensuring a durable, long-lasting product.
○ For frames 110–150, the housing is cast iron, offering enhanced durability and resistance to wear and tear.
• Worm and Worm Gear:
○ The worm is made from high-quality alloy steel, surface-hardened with a tooth surface hardness of 56–62 HRC. This provides excellent wear resistance and ensures long operational life.
○ The worm gear is constructed from premium, wear-resistant tin bronze, which guarantees superior strength and longevity.
• Self-Locking Characteristics:
○ Single-stage worm gear ratios offer superior self-locking characteristics, preventing back-driving and ensuring the system remains stationary when the motor is not engaged.
○ Multi-stage ratios reduce the self-locking effect but improve the overall transmission efficiency, providing versatility in application scenarios.

Product Advantages:
• Compact and Efficient Design: The compact design of the NMRV series gearboxes ensures space efficiency, making them an ideal choice for installations where space is limited.
• Maintenance-Free Operation: The gearbox is engineered for maintenance-free operation, reducing downtime and operational costs over the product lifecycle.
• Versatility in Gear Ratio: With a wide range of gear ratios and customizable configurations, the NMRV series provides optimal performance across various speed and torque requirements.
• Durable Construction: The choice of high-quality materials, including aluminum alloy and cast iron, ensures that the gearboxes have a long operational lifespan, even under heavy-duty conditions.
• Energy Efficiency: The gearboxes are designed to minimize energy consumption, contributing to more sustainable and cost-effective operations.
• Self-Locking and High Efficiency: Depending on the configuration, the NMRV series offers the ideal balance between self-locking and transmission efficiency, catering to different operational needs.

Product Applications:
The NMRV Series gearboxes are ideally suited for applications in various industries, including:
• Conveying Systems: Ideal for use in conveyors where consistent and reliable power transmission is required.
• Mixers and Agitators: In chemical processing and food industries, where precise control of speed and torque is crucial.
• Packaging Equipment: Offers efficient torque transmission and space-saving solutions for packaging machinery.
