Gear reducers are often used in various machinery and equipment. They are widely used in many industries. In actual production, some gear reducers may have abnormal faults such as noise, wear and oil leakage. Then how to solve these faults?
1. The gear reducer has abnormal sound or noise
Reason: The lubricating oil used in the gear reducer has many impurities or has not been lubricated and maintained in time, or the gear meshing part is damaged, or the gear gap is increased, the bearing gap is large, the bearing is damaged or worn seriously, etc.
Solution: Check the meshing parts of the gear reducer, replace damaged parts or adjust the bearing clearance according to the actual situation of the inspection, or replace the bearings of the damaged gear reducer.
2. The tooth surface of the gear reducer is worn or corroded
Reason: The lubricating oil of the gear reducer is of unqualified quality or contains impurities.
Solution: Replace the worn gears of the gear reducer, or replace the lubricant.
3. The bearing temperature of the gear reducer is too high
Reason: The oil level in the gear reducer is too low; the lubricant is too little, the lubricant is aging; the bearing is damaged.
Solution: Check the oil level of the gear reducer at room temperature, and supplement or replace the lubricating oil of the gear reducer according to the actual situation. Check the bearing, if it is abnormal, it may need to be replaced.
4. Oil seal leakage and oil leakage of gear reducer
Reason: oil seal seal failure of gear reducer
Solution: Check the wear of the shaft at the oil seal and replace the oil seal of the gear reducer.
5. High working temperature of gear reducer
Reason: The oil level in the gear reducer is too high or the amount of oil is low, the oil is aging, and the lubricating oil is seriously polluted.
Solution: Check the oil level, it may need to be corrected. Increase the lubricating oil to check when was the last oil change, the lubricating oil may need to be changed.
6.gear reducer gear teeth are broken
Reason: Overload work, gear reducer quality is not good enough.
Solution: Replace the broken parts of the gear reducer, recalculate the load to see if the selection is correct.
7.the input shaft of the gear reducer is broken
Reason: The radial force is too large, the installation error of the coupling is too large, and the quality of the gear reducer is not good enough.
Solution: Replace the broken parts of the gear reducer. When the user uses the pulley to input power, check whether the radial force exceeds the specified maximum value. Check whether the angular error of the coupling installation of the gear reducer is out of tolerance.
