Reducer troubleshooting? Safety first, pay attention to timely inspection and maintenance, 1. You can go to the repair shop to check the specific fault and find a professional maintenance person to check it. 2. It is recommended to operate and maintain according to the maintenance manual.Car owners are maintained regularly.Oil can be changed every kilometer.Some vehicles will prompt. 3. Go to the corresponding 4S shop or designated large-scale professional repair shop for service.In this way, the quality is guaranteed, and the after-sales service will be of high standard. Gear reducer maintenance: What are the skills of reducer maintenance? 1. The oil should be changed for the first time, the quality should be used in the future, and the oil mixed with impurities or deterioration should be replaced in time.Generally, for reducers that work continuously for a long time, new oil should be replaced according to the running time or every year.For reducers that have been out of use for a long time, new oil should also be replaced before restarting.The reducer should be filled with the same brand of oil as the original version, and must not be mixed with oil of different brands.Oils of the same brand, but different viscosities are allowed to be mixed; 2. When changing the oil, wait until the reducer cools down, there is no risk of burning, but keep warm, because after it is completely cooled, the viscosity of the oil increases and it is difficult to drain the oil.NOTE: Cut off power to the transmission unit to prevent unintentional power supply; 3. During operation, when the oil temperature rises above 80°C or the oil pool temperature exceeds °C, abnormal noise is generated, it should be stopped, the reason should be checked, the fault must be eliminated, and the operation can only be continued after the lubricating oil is replaced; 4. The user should use and maintain the rules and regulations reasonably, carefully record the problems in the operation and inspection of the reducer, and strictly implement the above regulations.Grease selection is based on the bearing load of the travel gear.When selecting a grease, choose a grease with low penetration for heavy loads.When working under high pressure, it has high oil film strength and extreme pressure function in addition to small penetration.Choose lubricating grease according to environmental conditions. Calcium lubricating grease is not easy to dissolve in water and is suitable for dry and less water environment.Grease is selected according to the operating temperature, the main indicators should be dropping point, oxidation stability and low temperature function.The dropping point can usually be used to evaluate the high temperature function, the actual working temperature of the bearing is 10-20℃ lower than the dropping point.The service temperature of synthetic greases is 20-30°C below the drop point. Different lubricants must not be mixed with each other.The positions of the oil level plug, oil drain plug and breather are determined by the installation position. Oil level check: 1. Cut off the power to prevent electric shock.Wait for the reducer to cool down; 2. Remove the oil level plug and check whether the oil is full; 3. Install the oil level plug. Water check: 1. Cut off the power to prevent electric shock.Wait for the reducer to cool down; 2. Open the oil drain plug and take an 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 the reducer with oil level plug: check whether the oil level is qualified; install the oil level plug. Change oil: After cooling, the viscosity of the oil increases, making it difficult to drain the oil.The reducer should change the oil at the working temperature. 1. Cut off the power to prevent electric shock.Wait until the reducer cools down and there is no danger of burning; Note: The reducer should be kept warm during the oil change; 2. Drain the oil under the drain plug; 3. Open the oil level plug, breather and drain plug; 4. Exclude all oil; 5. Install the oil drain plug; 6. Inject new oil of the same brand; 7. The amount of oil should be consistent with the installation position; 8. Check the oil level of the oil level plug; 9. Tighten the oil level plug and breathe.
