NRV Shaft Input Small Worm Gearbox Worm Gear Speed Reducer

NRV Shaft Input Small Worm Gearbox / Worm Gear Speed Reducer

NRV worm gearbox(NRV Shaft Input Small Worm Gearbox) is one of the RV series worm gearbox models. NMRV means flange input and NRV means shaft input. NRV worm gearbox is generally with a single input shaft, and there are also double input shaft forms, suitable for various transmission needs. The output forms include hollow hole output and flange output. Its internal transmission structure is composed of a worm and a worm gear, which has a compact structure, a large transmission ratio, and a self-locking function under certain conditions, NRV worm gearboxes manufactured by Power-trans own the advantages of smooth transmission and low noise.

NRV Shaft Input Worm Gearbox Specifications:

Advantages of NRV Worm Gearbox:

• Quick stop function

For a general gear reducer, it takes 5 to 10 seconds for the stop time, but for the NRV series, the stop state could be reached in only 2 to 5 seconds.

• High safety

The NRV worm gearbox adopts a different way compared with the traditional one in that it doesn’t need the sprocket and pulley. What’s more, the transmission structure is not exposed so that injuries to the operator could be reduced.

• Good protection

Grade IP55 is adopted which has good isolation for dust and moisture.

• Excellent thermal conductivity

The NRV worm gear is equipped with cooling ribs so that the body has excellent thermal conductivity and low temperature-rising.

• Long service life

The worm gearbox operates smoothly with low noise which is suitable for long-term contact work in harsh environments.

Applications of NRV Shaft Input Worm Gearbox

The NRV worm gearboxes are widely used in the automation industry, industrial robots, aerospace, CNC machine tools, metallurgical mining, beer and beverage, tobacco light industry, environmental engineering, warehousing logistics, plastics machinery, lifting transport, three-dimensional parking, automobile manufacturing, textiles, food, ceramics, and other fields.

NRV Shaft Input Worm Gear Reducer Precautious:

1. Before use, please confirm that the worm gear reducer and the mechanical safety supporting strength are within the safe range of the performance parameters of the worm gear reducer.
2. The worm gearbox has been filled with WA460 lubricant at the factory. After 400 hours of operation, the lubricant should be replaced. The oil change cycle is about 4000 hours later.
3. The worm gear reducer casing body should retain enough lubricating oil, and regularly check the amount of oil.
4. Avoid damage to the worm gearbox caused by sharp shaft damage caused by sharp equipment
5. Check the direction of rotation before installing the machine.
6. Set a safety cover, etc. in the rotation area.

Other Types of Worm Gearbox Combination Options:

(1) Input: with input shaft, With square flange, With IEC standard input flange
(2) Output: with torque arm, output flange, single output shaft, double output shaft, plastic cover
(3) Worm reducers are available with different combinations: NMRV+NMRV,NMRV+NRV, NMRV+PC, NMRV+UDL, NMRV+MOTORS
