WGT NMRV-Series Aluminum Housing Reducer

WGT NMRV-Series Aluminum Housing Reducer is a cost-effective and versatile worm gear reducer, widely recognized for its lightweight aluminum structure, compact size and stable transmission performance. Adopting ADC12 aluminum alloy die-casting housing, it is 40% lighter than cast iron counterparts, with excellent thermal conductivity to enhance heat dissipation efficiency, making it ideal for mobile and space-constrained equipment.

The core components are precision-manufactured for durability and smooth operation. The worm is made of 45# steel经过 quenching and grinding, ensuring high surface finish and transmission accuracy. The worm gear adopts wear-resistant tin bronze (ZCuSn5Pb5Zn5), which reduces meshing noise and extends service life by resisting abrasion. The optimized gear meshing design keeps operating noise below 65dB, suitable for noise-sensitive environments.

This series offers flexible configurations to meet diverse industrial needs. Its transmission ratio ranges from 5 to 100, with adaptable power output of 0.12kW to 4.0kW and maximum torque up to 320N·m. It supports multiple installation modes including horizontal, vertical and flange-mounted, with standard solid output shafts and optional hollow shafts. The housing complies with IEC standards, enabling direct connection to standard motors without custom adapters.

Equipped with IP54 standard protection, it resists dust and splashing water, with optional IP65 for harsher conditions. The double-seal structure (framework oil seal + O-ring) prevents oil leakage, while the visible oil level window facilitates daily maintenance. When the transmission ratio is ≥50:1, it features mechanical self-locking to avoid reverse rotation, ensuring operational safety in lifting and positioning scenarios.

Widely applied in automation production lines, food machinery, medical equipment, small conveyors and photovoltaic auxiliary devices, the NMRV-Series balances performance and cost-effectiveness. It serves as a core transmission component for light to medium-load scenarios, providing reliable, efficient and easy-to-maintain power support for various industrial equipment.
