For the daily maintenance of the KAF37-6.8-3KW gear reducer, in addition to checking the oil level, the following points are also crucial. Together, they ensure the stable operation and long life of the equipment.
1. Operating status monitoring
When the equipment is running, you should initially judge its health status through your senses:
1. Listen to the sound: Listen carefully to the operating sound of the reducer. Normal operating sound is smooth and even. High-frequency whistling, intermittent banging, or a low roar may indicate worn gears, loose couplings, or damaged bearings.
2. Temperature measurement: Monitor the temperature of the reducer shell. During normal operation, the housing temperature should not exceed 80°C. If the temperature rises abnormally, it may be caused by overload, insufficient or aging lubricating oil, poor heat dissipation, etc.
3. Feel vibration: Feel whether the device has abnormal vibration. Severe vibrations are often related to out-of-axis installation, loose anchor bolts, or worn internal parts.
2. Inspection of seals and fasteners
This part of the inspection can effectively prevent oil leakage and larger failures caused by looseness.
1. Check for leaks: Carefully observe the shaft end seal of the input/output shaft, the joint surface of the box and the oil drain plug to confirm whether there are signs of lubricating oil leakage.
2. Check the breathing valve (ventilation plug): Make sure the breathing valve is unobstructed. If the breathing valve is clogged, the internal pressure of the reducer will increase, thereby "squeezing" the lubricating oil out of the weak seal, causing oil leakage.
3. Fastening bolts: Regularly check and tighten all fasteners such as anchor bolts and flange connecting bolts to prevent loosening due to vibration.
