NRV-VS Dual Solid Shaft Input Worm Gearbox with Flange Output

NRV-VS Dual Solid Shaft Input Worm Gearbox with Flange Output

NRV-VS Dual Solid Shaf worm gearbox is an RV worm gear reducer that has the input solid shaft with extension, a double input form. The main function is to facilitate the use of additional accessories such as hand-cranking devices and encoder speed measurements for customers, and it can also realize the combination of multiple reducers.
RV worm gearbox has input types including hole input, shaft input, shaft input with extension, and flange input with extension. The output forms have hole output, one-way shaft output, two-way shaft output, and flange output. F…(1-2) means with output flange. VS means with the same direction input shaft. AS means is equipped with a one-way output shaft. AB means with the bidirectional output shaft.

Advantages of NRV-VS Dual Shaft Input Worm Gearbox:

• Quick stop function

For a general gear reducer, it takes 5 to 10 seconds for the stop time, but for the NRV-VS series, the stop state reach: 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-VS worm gearbox is equipped with cooling ribs so that the body has excellent thermal conductivity and low temperature-rising.

• Long service life

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

Applications of NRV-VS Dual Shaft Input Worm Gearbox

The NRV-VS worm gearboxes are widely working 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-VS Dual Shaft Input Worm Gearbox Operating Conditions:

(1) The NRV-VS worm gearbox has good versatility and is used with various mechanical equipment.
(2) A larger transmission ratio could be achieved by a single-stage transmission. Most types of speed reducers have a good self-locking ability, and mechanical devices with braking requirements can save braking devices.
(3) The meshing friction loss of the worm screw teeth and the surface of the worm gear to this large, so that the transmission efficiency should be lower than that of the gear.
(4) The NRV-VS worm gearbox has high requirements for lubrication and cooling.

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

NRV-VS Worm Gear Reducer Installation Precautions:

(1) Mount the reducer should stably to avoid any vibration.
(2) Before mounting make sure the output shaft of the reducer will turn in the correct direction.
(3) In case the reducer has been in store so long as 4 to 6 months, check the seal first, as it may stick to the shaft caused by lacking lubricant or lose its flexibility. If necessary, change the seal.
(4) For reduction units with a hollow output shaft, please use the torque arms. If it is not possible make sure that the shaft is without axial load.
(5) Whenever possible, protect the reducer from direct sunlight and any other bad weather.
(6) Make sure of good ventilating conditions.
(7) In the case of ambient temperatures <-5°C or >+40°C,contact technical department please.
(8) The various parts (pulleys, gear wheels, couplings, shafts, etc.) are mounted on solid or hollow shafts with a special screw thread that anyhow ensures correct operation without risking damage to the bearing or external parts of the units.
(9) Painting must definitely not go over rubber parts or the holes on the breather plugs.
(10) Checking the oil level.
(11) Supposing gear units have not been coupled with motors, please pay attention to the following items to make the sure right connection. Mounting to B5, B14.
(12) Checking whether the tolerance between shafts and motor flanges fits the essential standard.
(13) Washing the dirt and the paint on the surface of the shafts, center bores, and flanges.
(14) Lubricating the surface to avoid corruption.
(15) Starting must take place gradually, without immediately applying the maximum load.
(16) Some proper precautionary measures should be taken as the objects or materials under motor drives can be easily damaged.
