Grease selection When grease is selected according to the bearing load of walking reducer, grease with small penetration should be selected for heavy load. When working under high pressure, besides small penetration, it also needs high oil film strength and extreme pressure function. When grease is selected according to environmental premise, calcium-based grease is not soluble in water, so it is suitable for dry and less moisture environment. When selecting grease according to working temperature, main indexes should be dropping point, oxidation stability and low temperature function, dropping point can generally be used to evaluate high temperature function, and actual working temperature of bearing should be 10-20℃ lower than dropping point. The application temperature of synthetic grease should be 20-30℃ lower than the dropping point.

Different lubricating oils are forbidden to be mixed with each other. The positions of oil level plug, oil drain plug and breather 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;

2. Remove the oil level plug to check whether 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;

2. Open the oil plug and take an oil sample;

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

4. For reducer with oil level plug: check whether the oil level is qualified; Install the oil level plug.

Oil replacement:

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

1. cut off the power supply to prevent electric shock. Wait for the reducer to cool down without burning danger;

Note: the reducer should remain warm when changing oil;

2. Put an oil pan under the oil drain plug;

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

4. Eliminate all 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 breather.
