Common faults and solutions in gear reducer operation

Common faults and solutions in gear reducer operation:
1. Abnormal sound or noise of gear reducer
Reasons: There are many impurities in the lubricating oil; the gear meshing part is damaged, the gear clearance increases, and the bearing clearance is large; the bearing is damaged or severely worn.
Response: Check the meshing parts of the reducer, replace damaged parts, adjust the bearing clearance and replace damaged bearings.
2. Bearing temperature is too high
Reasons: The oil level in the reducer is too low; there is too little lubricating oil, the lubricating oil is aging; the bearing is damaged.
Response: Check oil level at room temperature and relubrication may be required.It may be necessary to change the lubricant when the last oil change was checked.Check bearings and replace if necessary.
3. Abrasion or erosion of tooth surfaces
Reason: The lubricating oil is unqualified or contains impurities.
Response: Replace worn gears and change lubricant.
4. Box cracking
Reasons: too much radial force, fractured gear teeth and quality problems.
Response: When users use chain drives to output power, it is very necessary to check the radial force.If the radial force exceeds the maximum value specified, a welded box or enlarged model should be used.
5. The input shaft is broken
Reason: The radial force is too large, the installation error of the coupling is too large, and the quality is poor.
Response: Replace the part.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 exceeds the tolerance.
6. Gear tooth fracture
Reasons: Overload work, equipment quality problems.
Response: Replace the part and recalculate the load to see if the type selection is correct.
