NMRV 1-Stage Gearboxes are worm gear reducers designed with a single transmission stage, functioning to reduce the motor rotation speed and increase the output torque for the system.
In terms of structure, the NMRV gearbox consists of main components such as an aluminum alloy or cast iron housing, worm shaft, worm wheel, bearings, oil seals, and a lubrication system. The worm and worm wheel drive mechanism provides effective speed reduction, stable operation, and minimized noise during operation. With various gear ratios, this gearbox series meets diverse speed reduction needs in production and automation.

Price list for NMRV 1-Stage Gearboxes at Thành Thái Motor
Below is the reference price list for NMRV 1-StageGearboxes at Thành Thái Motor, updated according to each size and popular gear ratio, helping customers easily choose the product that suits their usage needs and actual transmission systems.
Determine the correct gear ratio: The gear ratio determines the output speed of the gearbox. It is necessary to calculate the output shaft speed to match the operating requirements of the machinery before selection.
Check output torque: The gearbox must meet actual loads such as 50kg, 100kg, 200kg of the system to avoid overload, which causes gearbox heating or reduces the lifespan of the worm wheel and worm shaft.
Choose suitable housing material: For light load applications, aluminum housings can be used, while continuous working environments or heavy loads should prioritize cast iron housing gearboxes to increase durability.
Pay attention to installation style and shaft dimensions: It is necessary to check the input shaft, output shaft, flange dimensions, and installation position to ensure connectivity with the motor and transmission equipment.
Prioritize reputable suppliers: Customers should choose products with clear origins, complete technical specifications, and warranty policies to facilitate future maintenance and repair.

Frequently Asked Questions
Why does the NMRV 1-Stage Gearbox leak oil at the shaft end even after replacing with a new seal?
Besides a damaged seal, this phenomenon can also stem from a worn shaft journal, loose bearings, or a clogged vent hole, which increases the internal pressure inside the gearbox.
Why does the NMRV gearbox emit a loud humming noise when operating at high loads?
The cause is often related to a lack of lubricating oil, misalignment of the meshing clearance between the worm shaft and worm wheel, or internal bearings being damaged after long-term use.
Why does the NMRV 1-Stage Gearbox heat up above 80°C even though the amount of lubricating oil is sufficient?
Besides overloading, this phenomenon is usually related to worn bronze worm wheels increasing sliding friction, poor concentricity between the motor and gearbox, or a gear ratio unsuited to actual working conditions.
