HUAKE
The HUAKE NMRV Aluminum Worm Gear Box - RV40 is a highly practical transmission device that integrates advanced domestic and international technologies. As a flagship model in HUAKE’s NMRV series, this RV40 Worm Gear Box features an aluminum alloy housing, offering lightweight portability, superior heat dissipation, and low noise operation—addressing key pain points in industrial and household transmission systems. Unlike traditional worm gear boxes, it requires no coupling for connection to ordinary motors, stepless transmission machines, or flanged electromagnetic clutch brake sets, simplifying installation. With a wide speed ratio range (single-speed: 1/7.5–1/100; double-speed: 1/300–1/5000) and stable output torque, the RV40 is versatile across industries, from heavy machinery to daily household appliances.
The RV40’s housing is cast from high-strength aluminum alloy, reducing its weight by 30% compared to cast iron alternatives. This lightweight worm gear box is easy to transport and install, even in overhead or narrow spaces (e.g., ceiling-mounted conveyor drives). Additionally, aluminum alloy enhances heat dissipation performance, preventing overheating during long-term operation and extending component life.
A standout advantage is its ability to connect directly to motors and transmission devices without a coupling. This tool-free connection design saves installation time by 50%, eliminates alignment errors caused by couplings, and reduces overall system complexity—ideal for quick equipment upgrades or replacements.
Precision-machined worm gears and a sealed transmission structure ensure the RV40 operates at ≤60 decibels (similar to normal conversation). This low noise worm gear box is perfect for noise-sensitive environments, such as household appliances (e.g., washing machines) and indoor production lines.
With multiple mounting positions (AS1, AS2, BS1, BS2, PS1, PS2, VS1, VS2), the RV40 supports horizontal, vertical, and inverted installation. This flexibility allows it to fit diverse equipment layouts, from vertical pumps to horizontal conveyor drives, without custom brackets.
The RV40 Worm Gear Box offers both single-speed (1/7.5–1/100) and double-speed (1/300–1/5000) options. This range caters to low-speed, high-torque tasks (e.g., heavy machinery) and high-speed, low-torque applications (e.g., small household appliances), eliminating the need for multiple gear boxes.

The low noise worm gear box is widely used in household items like washing machines, air conditioners, and kitchen mixers. Its lightweight design and quiet operation enhance user experience, while aluminum alloy housing resists corrosion from moisture.
In excavators, loaders, and concrete mixers, the RV40’s stable output torque and durable aluminum alloy body withstand heavy loads and harsh working conditions. Its heat dissipation performance prevents overheating during long construction shifts.
For ship steering systems and automotive auxiliary components (e.g., windshield wipers), the corrosion-resistant worm gear box (aluminum alloy) tolerates saltwater and humidity. Its coupling-free connection simplifies on-board installation.
In food processing lines (e.g., bottling machines) and electronic component assembly equipment, the RV40’s precise speed control (via wide gear ratios) ensures consistent product quality. Its easy maintenance also reduces downtime in high-speed production.
In trains and trams, the RV40 drives auxiliary systems like ventilation fans and door mechanisms. Its all-round installation flexibility fits the limited space in locomotive cabins, while low noise operation avoids disturbing passengers.
No—this NMRV worm gear box connects directly to motors without a coupling, saving installation time and reducing alignment issues.
Thanks to its aluminum alloy heat dissipation, the RV40 operates reliably at ambient temperatures of -10°C to 40°C. For higher temperatures, we recommend additional cooling measures.
Yes, it supports double-speed transmission with a speed ratio range of 1/300 to 1/5000, suitable for low-speed, high-torque industrial tasks.
Absolutely—its modular design allows seamless connection to stepless transmission machines, making it ideal for applications requiring adjustable speed (e.g., printing machines).
Routine maintenance includes annual lubricant replacement (use industrial gear oil) and quarterly inspections of the housing for cracks. This ensures a service life of 7–9 years under normal use.
