How to repair and maintain the loader gearbox |
Public date:2018-7-27 Hits：17521 |
Hydraulic transmission oil is the energy carrier for the normal operation of the gearbox. In the hydraulic transmission system, the pressure, temperature and flow of the working fluid determine whether the transmission can work normally. Therefore, special attention should be paid to the daily maintenance of the transmission. Inspection and replacement of hydraulic transmission oil. 1. Fixed oil change interval
Changing oil at the right time intervals is the key to getting the longest working life of the components in the gearbox. Lubrication and protection of lubricating oils can only be achieved if a reasonable oil change interval is ensured.
Under normal circumstances, it should be based on the maintenance cycle recommended by the whole machine manufacturer, but this can only be relative. It must be combined with the oil sample extraction analysis results to know the actual working conditions. For example, in the maintenance manual, the oil change interval of the gearbox is 1000h. According to the operation of the loader, the oil sample is sampled every 500h or 250h to determine when to change the oil, but the oil should be used up to 1000h. Replace it now. In addition to regular replacement of new oil, in the usual inspection, if the oil is found to be deteriorated or mixed with impurities, it should also be cleaned and replaced with new oil.
2, using the correct row, oil change method
When draining oil, the oil temperature should reach 40~50 °C, and the oil flow should be discharged under agitation. The dirty oil should be drained as completely as possible. When refueling, the oil should be added by using a tanker with a filtering device.
3. Use the correct transmission system oil, the lubricant used in the gearbox must meet the specifications.
4. Refer to the replacement filter period provided in the service manual and replace the filter in time.
5, all kinds of lubricants must be pure, and after a period of precipitation, in line with the specified quality requirements.
Therefore, it is necessary to strengthen the fault prevention and daily maintenance of the gearbox during daily use, which not only can reduce the work efficiency caused by the shutdown and maintenance, delay the working hours, but also prevent and avoid further follow-up faults. The occurrence, reduce maintenance costs, improve the safety of the machine. |
