List some common faults and solutions for ZSC320 reducer

Gear wear

Fault manifestation: abnormal noise occurs during the reducer operation, the transmission efficiency decreases, and sometimes lag occurs.

Cause analysis: Long-term high-load operation, insufficient lubrication, poor gear material or insufficient gear meshing accuracy may all lead to gear wear.

Solution: Check the wear of the gear regularly and repair or replace it according to the wear level. Optimize the lubrication system to ensure the gears are well lubricated. Select gears with reliable quality to improve gear processing and installation accuracy.

Bearings damaged

Fault manifestation: The vibration increases, the temperature increases, and abnormal noise when the reducer is running. In severe cases, the reducer cannot operate normally.

Cause analysis: Factors such as excessive bearing load, poor lubrication, bearing quality problems, and improper installation may cause bearing damage.

Solution: Replace damaged bearings and select the appropriate bearing model to ensure that their load-bearing capacity meets the operating requirements of the reducer. Improve lubrication conditions, check and replace lubricant regularly. When installing bearings, you must strictly follow the installation requirements to ensure installation accuracy.

Oil leak

Fault manifestation: There are oil marks on the surface of the reducer shell and the oil level gradually drops.

Cause analysis: The seal is aging and damaged, the uneven joint surface of the box, excessive oil level or blocked ventilation holes may all lead to oil leakage.

Solution: Replace aging or damaged seals, such as oil seals, O-rings, etc. Repair or reprocess the joint surface of the box to ensure that the joint surface is flat. Adjust the oil level to normal height, clear the ventilation holes, and ensure the pressure balance inside and outside the box.

The oil temperature is too high

Fault manifestation: After the reducer is running for a period of time, the oil temperature exceeds the specified value, and even smoke occurs.

Cause analysis: Excessive load, poor heat dissipation, improper lubricant selection or deterioration of oil quality may all lead to excessive oil temperature.

Solution: Adjust the load reasonably to avoid long-term overload operation of the reducer. Improve heat dissipation conditions, such as cleaning the heat sink, adding cooling fans, or checking whether the cooling system is working properly. Select the right lubricant, check the quality of the oil regularly, and replace the deteriorated lubricant in time.

Too much noise

Fault manifestation: The reducer makes harsh or abnormal noise during operation.

Cause analysis: In addition to the noise caused by wear and bearing damage, poor gear meshing, unstable installation of reducer, uneven foundation or different centers of the motor and reducer can also cause noise.

Solution: Adjust the gear meshing clearance to meet the requirements. Check the installation of the reducer to ensure that the installation is firm and the foundation is flat. Adjust the connection between the motor and the reducer to ensure that the two are concentric.

Transmission accuracy decreases

Fault manifestation: The speed and steering of the reducer output shaft differ from the theoretical value, which affects the normal operation of the working mechanism.

Cause analysis: Gear wear, increased bearing clearance, damage to the coupling or loose internal parts of the reducer may all lead to a decrease in transmission accuracy.

Solution: Perform corresponding treatments for different reasons, such as replacing worn gears and damaged couplings, adjusting bearing clearance, tightening loose parts, etc.

Motor overload

Fault manifestations: The motor current is too high, the motor heats up severely, and even the protection device trips.

Cause analysis: The motor may be overloaded by excessive load of the reducer, the transmission parts are stuck, the motor and the reducer are not matched or the power supply voltage is abnormal.

Solution: Check the load condition, reduce the load or replace the reducer with a higher power. Troubleshoot the stagnation of the transmission parts to ensure smooth transmission. Select the appropriate motor to match the reducer, check the power supply voltage to ensure that it is stable within the specified range.

High vibration of reducer

Fault manifestation: The overall vibration of the reducer is obvious, affecting the stability and service life of the equipment.

Cause analysis: In addition to the bearing damage and unstable installation, unbalanced gears, foreign objects inside the reducer, insufficient foundation stiffness, etc. may also cause vibration.

Solution: Perform dynamic balance tests on the gears, adjust or replace unbalanced gears. Clean foreign matter inside the reducer, strengthen the foundation, and improve the stiffness of the foundation.
