描述
EP-NRV030 Solid Shaft Aluminium Worm Gearbox – Product Overview
这 EP-NRV030 is the entry-level NRV solid-shaft worm gearbox for light-duty conveyor and food processing drives, offering 11 ratios and universal motor coupling. With a solid Ø9j6 input shaft instead of an IEC motor flange, the NRV030 accepts any motor type via standard shaft coupling – servo motors, stepper motors, DC brushless, hydraulic motors, and even combustion engine PTO drives. This universal motor compatibility is the defining advantage of the NRV series over the IEC-flange-only NMRV series. At approx. 1.5 kg with 30 mm centre distance and Ø14g6 output shaft, it delivers up to 21 Nm output torque across ratios 5-80:1. The die-cast aluminium alloy housing provides corrosion resistance and thermal efficiency superior to cast iron while saving 30-50% in weight. Purpose-designed for food-grade belt conveyors, retail turntables, and packaging actuators where the solid input shaft enables coupling to washdown-rated servo motors and variable-speed DC drives.

✓ 核心功能和优势
与 IEC 法兰 NMRV 系列不同，NRV 实心输入轴可通过标准轴联器与任何类型的电机连接——交流感应电机、直流无刷电机、伺服电机、步进电机、液压电机、气动电机和内燃机 PTO 驱动器。
The widest ratio range in the small NRV sizes. Solid 9 mm j6 input shaft accepts any motor type via standard coupling – not restricted to IEC flange motors like the NMRV030.
Output shaft matches standard 14 mm bore couplings and sprocket hubs used across light-duty Australian industrial applications. Direct fit without adaptor sleeves.
压铸铝外壳的散热速度是铸铁的三倍，可在高达 40°C 的环境温度下连续运行。出厂涂层可抵抗潮湿、化学品冲洗和轻微盐雾侵蚀。
⚙ 行业应用
Corrosion-resistant aluminium worm gearbox for belt conveyors in food processing. Solid shaft accepts food-grade servo drives for variable-speed washdown applications.
Ultra-quiet foot-mount worm gearbox for motorised display platforms. 80:1 ratio delivers slow smooth rotation below 65 dB(A) noise level suitable for showroom environments.
实心轴输入可与柴油液压马达、发动机动力输出轴驱动器和电池供电的直流电机连接——不仅限于市电供电的IEC电机。是偏远地区采矿、农业和建筑业的必备设备。
通过波纹管或梁式联轴器直接耦合伺服电机或步进电机，适用于位置控制应用。可实现IEC法兰蜗轮减速器无法比拟的角度精度。
⚙ 选择指南和安装位置
Choose the NRV030 when you need universal motor coupling flexibility – servo, stepper, DC, hydraulic, or PTO. If your application uses only standard IEC AC motors, the NMRV030 with direct flange mount may offer a simpler installation. Both NRV and NMRV share identical output shaft specifications, torque ratings, and housing dimensions at each size.

⚖ NRV铝制蜗轮减速器与铸铁蜗轮减速器对比
与传统的铸铁减速器相比，NRV 铝制蜗轮减速器重量显著减轻，耐腐蚀性更强，散热性能更佳——此外，通过实心输入轴，还可实现通用电机联轴器。
| 特征 | 铝制止回阀 | 铸铁 |
|---|---|---|
| 重量 | 30-50% 打火机 | 较重 |
| 腐蚀 | 出色的 | 贫穷的 |
| 热 | 优越的 | 缓和 |
| 成本 | 降低 | 更高 |
| 输入轴 | 固体通用联轴器 | 通常固定法兰 |
| 电机兼容性 | 通过联轴器的任何电机 | 通常仅限IEC标准 |
