2024-11-02

The sound of the gear reducer is abnormal or there is noise Reason: There are many impurities in the lubricating oil; The gear meshing area is damaged, the gear clearance increases, and the bearing clearance is large; The bearings are damaged or severely worn. Response: Check the meshing parts of the reducer, replace damaged parts, adjust the bearing clearance, and replace damaged bearings. The bearing temperature is too high Reason: The oil level in the reducer is too low; Too little lubricating oil, the lubricating oil has aged; The bearing is damaged. Response: Check the oil level at room temperature, and it may be necessary to replenish lubricating oil. When was the last time the oil was changed? It may be necessary to replace the lubricating oil. Check the bearings, they may need to be replaced.

Common faults and solutions in the operation of gear reducers

The sound of the gear reducer is abnormal or there is noise

Reason: There are many impurities in the lubricating oil; The gear meshing area is damaged, the gear clearance increases, and the bearing clearance is large; The bearings are damaged or severely worn.

Response: Check the meshing parts of the reducer, replace damaged parts, adjust the bearing clearance, and replace damaged bearings.

The bearing temperature is too high

Reason: The oil level in the reducer is too low; Too little lubricating oil, the lubricating oil has aged; The bearing is damaged.

Response: Check the oil level at room temperature, and it may be necessary to replenish lubricating oil. When was the last time the oil was changed? It may be necessary to replace the lubricating oil. Check the bearings, they may need to be replaced.

Wear or corrosion of tooth surface

Reason: The lubricating oil is of poor quality or contains impurities.

Response: Replace worn gears and change lubricating oil.

Box cracking

Reason: Excessive radial force, gear tooth fracture, quality issue.

Response: When users use chain transmission to output power, it is necessary to verify the radial force. If the radial force exceeds the specified maximum value, welded boxes or enlarged models should be used.

Input shaft fracture

Reason: The radial force is too large, the installation error of the coupling is too large, and there are quality issues.

Response: Replace parts. When the user inputs power with the pulley, check whether the radial force exceeds the specified maximum value. Check if the angle error of the coupling installation exceeds the tolerance.

Gear tooth fracture

Reason: Overloading work, gear quality issues.

Response: Replace the parts and recalculate the load to see if the selection is correct.
