RV Series 040 Worm Reducer-Replacement of NMRV 040 Worm Gearbox

The NMRV 040 gearbox is a versatile industrial gearbox with many uses. It is suitable for a variety of industries, including mining, metallurgy, automation, tobacco, food machinery, and packaging. The worm and gear are made of 10-1 tin bronze, which provides excellent casting properties. The gear uses 20CR alloy structural steel, which has high hardenability, strength, and wear resistance. Synthetic oil is used for high-speed bearings and seals to reduce friction. High-quality aluminum alloy casting is lightweight and durable. Military manufacturing technology ensures smooth transmission, low noise, and good heat dissipation. Its fine appearance is ideal for all-round installation.

How to Change Oil in NMRV 040 Reducer?

You should always check the oil level in your NMRV 040 worm gearbox regularly. The amount of oil in the reducer should not be less than the manufacturer's recommended level. Improper oil levels can cause premature gear failure. It may also cause excessive churning and air entrapment. To prevent any problems, check the oil level while the reducer is off and after sufficient cooling.

Before changing the oil, you should inspect the worm gearbox. It should be free from jamming and flexible. Oil and grease are recommended. The transmission shaft and installation foundation should be in the normal position. Before replacing the parts, you should test them for proper load and durability. Then, you can replace the damaged parts with new ones. Make sure that you check the oil level and condition before using them.
