1. The first oil change should be performed after 200-300 hours of operation. Regular oil changes should be performed during subsequent use.
Regularly check the oil quality; replace any oil contaminated with impurities or deteriorated. Generally, for speed reducers operating continuously for extended periods, change the oil every 5000 hours or annually. For speed reducers that have been out of service for a long time, change the oil before restarting. The speed reducer should be filled with the same brand of oil as before; do not mix oils of different brands. Oils of the same brand but different viscosities may 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 kept warm. This is because once completely cooled, the oil viscosity increases, making draining difficult. Note: Disconnect the power supply to the transmission device to prevent accidental energization.
3. During operation, if the oil temperature rises above 80℃ or the oil sump temperature exceeds 100℃, or if abnormal noise is generated, the operation should be stopped, the cause should be checked, the fault must be eliminated, and the lubricating oil should be replaced before the operation can continue.
4. Users should have reasonable rules and regulations for use and maintenance, and should keep careful records of the operation of the reducer and the problems found during inspection. The above regulations should be strictly followed.
Inspection and maintenance
When selecting grease based on the bearing load of the travel reducer, a grease with a low penetration should be chosen for heavy loads. When operating under high pressure, in addition to low penetration, high oil film strength and extreme pressure performance are also required. When selecting grease based on environmental conditions, calcium-based greases are not easily soluble in water and are suitable for dry environments with low moisture content. When selecting grease based on operating temperature, the main indicators should be dropping point, oxidation stability, and low-temperature performance. The dropping point is generally used to evaluate high-temperature performance; the actual operating temperature of the bearing should be 10-20°C lower than the dropping point. The operating temperature of synthetic greases should be 20-30°C lower than the dropping point.
Different lubricating oils must not be mixed. The positions of the oil level plug, drain plug, and breather are determined by the installation location.
Oil level check:
1. Disconnect 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 level is full;
3. Install the oil level plug.
Oil inspection:
1. Disconnect the power supply to prevent electric shock. Wait for the reducer to cool down;
2. Open the drain plug and take an oil sample;
3. Check the oil's viscosity index: If the oil is noticeably cloudy, 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 within acceptable limits; install the oil level plug.
Oil change:
After cooling, the oil viscosity increases, making it difficult to drain. The reducer should have its oil changed at operating temperature.
1. Disconnect the power supply to prevent electric shock. Wait until the reducer has cooled down and there is no longer a risk of combustion.
Note: The gearbox should still be warm when changing the oil;
2. Place an oil collection tray under the drain plug;
3. Open the oil level plug, breather, and drain plug;
4. Drain all the oil;
5. Install the drain plug;
6. Inject new oil of the same brand;
7. The oil level should be consistent with the installation location;
8. Check the oil level at the oil level screw plug;
9. Tighten the oil level plug and breather.
