NRV Series Worm Gear Reducer is a versatile and efficient power transmission solution suitable for a wide range of industrial applications.
It is a reliable and versatile power transmission solution that can be applied across a wide range of industries, including material handling, industrial automation, machinery and equipment, food and beverage processing, renewable energy, mining and quarrying, marine and offshore, and general industrial applications.
High Efficiency: The NRV series utilizes a worm wheel made from bronze Cu Sn12 Ni2 (UNI7013-10) and a ground worm profile ZI (UNI4760), which provides high efficiency and load-bearing capacity in compliance with international standards such as ISO 14521, DIN 3996, BS 721, AGMA 6034, ISO 6336, DIN 3990, DIN 743, and ISO 2812.
Flexible Configuration: The NRV series is available in various configurations, including a single-stage gear with an IEC motor adaptor (NMRV), a double-stage worm gear (NMRV-NMRV), and integrated helical/worm combinations (PC-NMRV). This modularity allows the NRV to be tailored to a wide range of power ratings and application needs.
Broad Reduction Ratios: The NRV series offers reduction ratios ranging from 5 to 1000, making it suitable for a diverse array of industrial applications, such as conveying, material handling, packaging, winches, and automated guided vehicles (AGVs).
Versatile Mounting: The NRV series can be supplied with synthetic oil for universal mounting positions, eliminating the need for lubricant modifications. This feature enhances the flexibility and ease of installation.
Durability and Accessories: The NRV series is typically painted with RAL 5010 blue epoxy-polyester powder for enhanced durability. Additionally, it offers various accessories, such as hand-cranking devices and encoder speed measurements, which facilitate the combination of multiple reducers. 
1. Housing: die-cast aluminum aloy(rame size 025 to 090);cast iron(rame size:110 to 150);
2. Worm: 20Cr, carbonize&quencher heat treatment make the hardness of gear's surface up to
56-62HRC,retain carburation layer's thickness between 0.3 and 0.5mm after precise grinding.
3. Worm wheel: wearable stannum bronze alloy.
