Provide a daily maintenance guide for SA57D90S/1.1KW/12.1/M1/0 gearbox

The following is a daily maintenance guide for the SA57D90S/1.1KW/12.1/M1/0 gearbox:

Daily check

Appearance inspection: Check whether there are cracks, deformations, or damages on the gearbox housing, and whether the bolts at each connecting part are loose. If they are loose, they should be tightened in a timely manner.

Running sound: Listen for any abnormal noise or vibration during the operation of the gearbox. If there is an abnormal sound, it may be due to gear wear, bearing damage, or other component failure, and it is necessary to stop the machine for inspection in a timely manner.

Temperature check: Touch the gearbox housing with your hand to feel if the temperature is too high. Generally speaking, the temperature of the gearbox during normal operation should not exceed 80 ℃. If the temperature is too high, it may be caused by excessive load, poor lubrication, or poor heat dissipation. The cause needs to be identified and resolved.

Weekly inspection

Lubricating oil level: After shutdown, wait for a period of time for the lubricating oil to flow back to the oil pan, then open the oil level inspection hole to check if the oil level is within the specified range. When the oil level is too low, lubricating oil should be replenished in a timely manner. If it is too high, excess lubricating oil should be discharged.

Lubricating oil quality: Observe the color, transparency, and viscosity of the lubricating oil. If the oil quality turns black, cloudy, has an odor, or shows a significant change in viscosity, it indicates that the lubricating oil has deteriorated and needs to be replaced in a timely manner.

Ventilation device: Check if the ventilation opening of the gearbox is unobstructed and if there is any dust or debris blocking it. Good ventilation helps to dissipate heat from the gearbox. If the ventilation opening is blocked, it can cause an increase in internal temperature, affecting the performance and lifespan of the gearbox.

monthly inspection

Gear wear condition: Open the observation hole of the reducer, use professional tools (such as calipers, dial gauges, etc.) to check the wear condition of the gears, measure the tooth thickness, tooth profile and other parameters of the gears, and compare them with the original data. If the gear wear exceeds the specified range, the gear should be replaced in a timely manner to avoid serious faults such as gear fracture.

Bearing inspection: Check the operating condition of the bearing by listening to sound, feeling vibration, or using a bearing tester. If abnormal noise, vibration or high temperature are found in the bearing, it may be damaged and needs to be replaced in a timely manner.

Seal inspection: Check the sealing parts of the reducer, such as the shaft end seal and the box joint surface seal, for any oil leakage. If aging or damage is found in the seals, they should be replaced in a timely manner to prevent lubricating oil leakage and affect the normal operation of the gearbox.

regular maintenance

Lubricating oil replacement: Regularly replace the lubricating oil according to the user manual and actual operating conditions of the reducer. In general, a new gearbox should undergo its first oil change after running for 200-300 hours, and then change the lubricating oil every 3000-5000 hours or every six months to one year thereafter. When replacing the lubricating oil, the old oil inside the gearbox should be drained first, then the interior should be rinsed with clean oil, and finally new lubricating oil should be added.

Filter replacement: The lubricating oil filter of the gearbox should be replaced regularly, usually every 1000-2000 hours of operation or every three months. Blockage of the filter can cause poor circulation of lubricating oil, affecting the lubrication effect. Therefore, it is necessary to replace the filter in a timely manner to ensure the cleanliness of the lubricating oil.
