When encountering the problem of excessive temperature rise of the WB85-WD-11-180W reducer, we can quickly solve it in three steps: first stop the machine for troubleshooting, then deal with it in a targeted manner, and finally strengthen prevention . The specific plans are as follows:
1. Immediately stop the machine for inspection
Safety first: Cut off the power supply to avoid burns from hot parts.
Preliminary Observation: Check whether the lubricating oil is turbid, whether the oil level is normal, and listen for abnormal noises.
2. Troubleshooting and handling of core issues
1. Lubrication system problems
Abnormal oil level: If the oil level is too high, it will increase the oil stirring resistance, and if it is too low, there will be insufficient lubrication. After stopping the machine to cool down, adjust the oil level to the middle position of the oil level gauge.
Oil product problem: If the oil is oxidized and deteriorated or mixed with impurities, the old oil needs to be completely drained, and the inside of the gear box should be flushed 2 to 3 times with new oil of the same type and then refilled.
2. Loading and installation issues
Overload operation: Check the load conditions and reduce the operating load to within 80% of the rated load.
Installation deviation: Use a dial indicator to check the coaxiality of the coupling to ensure that the radial runout is ≤0.1mm and the axial runout is ≤0.05mm.
3. Cooling system optimization
Dust protection: Install a dust cover on the outside of the heat sink, and use compressed air to blow out the heat dissipation channel after shutting down every day.
Oil-cooled heat exchanger: Use a backwash device and use high-pressure water to backwash once a week to remove dust accumulation on the fins.
3. Long-term maintenance suggestions
Replace lubricating oil regularly: Choose the appropriate oil according to the working conditions. For high temperature and heavy load, choose ISO VG 320 heavy-duty gear oil.
Optimize the installation environment: Install the reducer in a well-ventilated location away from heat sources, and install an awning during open-pit drilling.
Intelligent monitoring: Install a temperature control device or intelligent monitoring system to provide early warning of overheating risks.
