Nmrv 030 Worm Gearbox

The nmrv 030 worm gearbox is widely used in many fields, such as packaging equipment in the food industry, conveying equipment in the logistics industry, ceramics, chemicals, glass, and woodworking. The following is the nmrv 030 worm gearbox,Some of the maintenance methods below

Technique:

1.After running for 200 to 300 hours, the first oil change should be carried out. During subsequent use, the quality of the oil should be regularly checked. Oil mixed with impurities or deteriorated should be replaced in a timely manner. Under normal circumstances, for reducers that operate continuously for a long time, new oil should be replaced every 5,000 hours of operation or once a year. For reducers that have been idle for a long time, new oil should also be replaced before they are put back into operation. The reducer should be filled with oil of the same grade as the original one. It is not allowed to mix oil of different grades. Oil of the same grade but different viscosities can be mixed.

2. When changing the oil, wait until the reducer has cooled down to a point where there is no risk of combustion, but it should still be warm. This is because after complete cooling, the viscosity of the oil increases, making it difficult to drain. Note: The power supply of the transmission device should be cut off to prevent accidental power-on.

3. During operation, if the oil temperature rise exceeds 80℃ or the oil pool temperature exceeds 100℃, or abnormal noises occur, the use should be stopped immediately. Check the cause, eliminate the fault, and replace the lubricating oil before resuming operation.

4. Users should have reasonable usage and maintenance rules and regulations. They should carefully record the operation status of the reducer and the problems found during inspection. The above regulations should be strictly followed.

Maintenance:

When choosing grease based on the bearing load of the walking reducer, for heavy loads, grease with a small penetration should be selected. When working under high pressure, in addition to having a small penetration, it is also necessary to have a high oil film strength and extreme pressure performance. Calcium-based grease has excellent water resistance and is not prone to emulsification or deterioration when exposed to water. It can be used for lubricating various mechanical parts in damp environments or in contact with water. When choosing grease based on the working temperature, the main indicators should be the dropping point, oxidation stability and low-temperature performance. The dropping point can generally be used to evaluate the high-temperature performance. The actual working temperature of the bearing should be 10-20℃ lower than the dropping point. The operating temperature of synthetic grease should be 20-30℃ lower than its dropping point.

Different lubricating oils must not be mixed with each other. The positions of the oil level plug, the oil drain plug and the vent are determined by the installation position.

Oil level check:

1.Cut off the power supply to prevent electric shock. Wait for the reducer to cool down;

2. Remove the oil level plug to check if the oil is full.

3. Install the oil level plug.

Inspection of oil:

1.Cut off the power supply to prevent electric shock. Wait for the reducer to cool down;

2. Open the oil drain plug and take the oil sample.

3. Check the viscosity index of the oil: If the oil is obviously turbid, it is recommended to replace it as soon as possible.

4. For reducers with oil level plugs: Check the oil level to see if it is qualified; Install the oil level plug.

Oil replacement:

After cooling, the viscosity of the oil increases, making it difficult to drain. The oil of the reducer should be changed at the operating temperature.

Cut off the power supply to prevent electric shock. Wait until the reducer cools down and there is no risk of combustion.

Note: When changing the oil, the reducer should still be kept warm.

2. Place an oil collection tray under the oil drain plug.

3. Open the oil level plug, vent and oil drain plug;

4. Drain all the oil.

5. Install the oil drain plug;

6. Inject new oil of the same brand;

7. The oil quantity should be consistent with the installation position.

8. Check the oil level at the oil level plug.

9. Tighten the oil level plug and the vent.
