Grease selection

When selecting the grease according to the bearing load of the traveling reducer, grease with small penetration should be selected for the heavy load. When working under high pressure, in addition to the small penetration, but also have a higher oil film strength and extreme pressure function. When greases are selected based on environmental conditions, calcium-based greases are not easily soluble in water and are suitable for drying and less water. When selecting the grease according to the operating temperature, the main indicators should be drop point, oxidation stability and low temperature performance. The dropping point can generally be used to evaluate the high temperature performance. The actual operating temperature of the bearing should be lower than the dropping point of 10-20°C. The use temperature of synthetic grease should be lower than the dropping point 20-30 °C.

Different lubricants are prohibited from mixing with each other. The position of the oil level plug, the oil drain plug and the aerator is determined by the mounting position.

 

Oil level check:

1, cut off the power 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.

Oil inspection:

1, cut off the power to prevent electric shock. Wait for the reducer to cool;

2, open the oil plug, take the oil sample;

3, check the oil viscosity index: If the oil is significantly muddy, it is recommended to replace as soon as possible;

4. For the speed reducer with oil level screw plug: check the oil level, whether it is qualified; install the oil level screw plug.

 

Oil replacement:

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

1, cut off the power to prevent electric shock. Wait for the reducer to cool down without any danger of combustion;

Note: The reducer should still keep warm when changing oil;

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

3, open the oil level plug, aerator and oil drain plug;

4. Remove all oil;

5, install oil drain plug;

6. Inject new oil of the same brand name;

7, the amount of oil should be consistent with the installation location;

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

9. Tighten oil level plugs and aerators.
