6 Key Maintenance Points for Planetary Reducers
Release time:
Nov 10,2025
Information Summary:
The maintenance of planetary reducers directly affects their lifespan (normal maintenance can extend the lifespan to 8-10 years, while improper maintenance may only last 3-5 years). It is essential to strictly follow the following 6 points:
Lubrication Management (Core):
Lubricating oil selection: Use L-CKC 220 industrial gear oil for general types, synthetic gear oil (such as PAO-based) for precision types, and low-temperature gear oil (pour point ≤ -30℃) in low-temperature environments (<-10℃). Please provide the text you would like translated.
Oil change cycle: For new equipment, the first oil change should be carried out after 50 hours of operation. Subsequently, oil changes should be conducted every 2000 hours (every 1500 hours for precision models and every 1000 hours for explosion-proof models). Please provide the text you would like translated.
Oil level check: Check the oil level weekly and keep it at 1/2 to 2/3 of the oil gauge. Add the same type of oil in time if it is insufficient. Please provide the text you would like translated.
Temperature Monitoring:
Normal operating temperature ≤ 70℃. If it exceeds 80℃, the machine needs to be shut down for inspection. Possible causes: insufficient or deteriorated lubricating oil, overload operation, or bearing damage. Please provide the text you would like translated.
It is suggested that a temperature sensor be installed on the outer shell to monitor the temperature in real time. An automatic alarm will be triggered when the temperature exceeds the threshold. Please provide the text you would like translated.
Seal inspection:
Check the input/output shaft oil seals monthly. If leakage (oil drops/oil stains) is found, replace the oil seals promptly (fluoro rubber is recommended, with a temperature resistance range of -20 to 200℃). Please provide the text you would like translated.
For explosion-proof types, the flameproof surface should be inspected. If there are scratches (depth > 0.5mm), they need to be ground and repaired to ensure the flameproof performance. Please provide the text you would like translated.
Vibration and noise detection:
The vibration value is detected by a vibration detector every quarter. For the common type, it should be ≤ 4.5mm/s, and for the precision type, it should be ≤ 2.5mm/s. Please provide the text you would like translated.
If the noise suddenly increases (exceeding 75 dB), it may be due to gear wear (tooth surface spalling / pitting) or excessive bearing clearance. The machine needs to be disassembled for inspection. Please provide the text you would like translated.
Cleaning and Maintenance:
Clean the dust on the shell weekly to avoid poor heat dissipation. Please provide the text you would like translated.
Precision reducers need to be regularly cleaned with compressed air (below 0.3 MPa) to clear the heat dissipation holes and prevent blockage. Please provide the text you would like translated.
Regular maintenance:
A comprehensive inspection should be carried out once a year: disassemble and check the gear tooth surface (wear ≤ 0.1mm is normal), bearing clearance (for ordinary bearings ≤ 0.05mm, for precision bearings ≤ 0.02mm), and deformation of the planet carrier (bending degree ≤ 0.1mm/m). Please provide the text you would like translated.
Replace aged parts (such as oil seals and O-rings), ensure coaxiality when reassembling, and apply sealant (silicone sealant for precision types, with a temperature resistance range of -60 to 200℃).
