The core to determine the actual operating load type of the ZFY560-112-2 gear reducer is to conduct a comprehensive evaluation based on the drive equipment characteristics, working machine operating conditions and field operation data. The conclusion cannot be made based on a single indicator. For the hard-tooth surface reducer you are interested in, it is usually necessary to determine whether it is a 'constant load', 'slight impact' or 'strong impact load' by observing the operating noise and vibration, measuring the motor current fluctuations, and comparing the working condition coefficient table.
To accurately define the load type of ZFY560-112-2, it is recommended to cross-verify from the following three dimensions:
1. The matching characteristics of the driving source and the working machine (theoretical prediction) This is the most basic basis for judgment. You need to confirm the motor power connected to the reducer, the starting method and the type of back-end load machinery.
Constant load: If the rear end is connected to a belt conveyor, centrifugal pump or fan that feeds uniformly and starts smoothly, it usually falls into this category.
Slight impact load: If used in scrapers, low-speed mixers with uneven material distribution (materials may be slightly agglomerated) or ordinary machine tool feed mechanisms, the load will fluctuate slightly (the peak value does not exceed 1.2~1.5 times the rated torque), which falls into this category.
Strong impact load: If applied to crushers, rolling mills or heavy lifting equipment that frequently starts and stops, the load peak may far exceed the rated value, and it must be treated as a strong impact load.
2. Observation of on-site operating phenomena (qualitative analysis) Use your rich on-site experience to make preliminary diagnosis through 'listening' and 'seeing':
Listen to the sound: There should be a steady 'buzzing' sound during normal operation. If you hear periodic banging or sharp meshing noises, it often means there is an impact load.
Look at vibration: Use a vibration meter to check the vibration value of the bearing seat. The vibration waveform is smooth under constant load; if there are periodic spikes or large fluctuations, it indicates the presence of impact.
Check the temperature rise: Under the same ambient temperature, if the oil temperature of the reducer rises abnormally and is accompanied by an increase in noise, it may be that long-term overload or impact load causes a decrease in efficiency.
3. Motor current monitoring (quantitative analysis) This is the most objective data support method. It is recommended to install a current recorder on the motor at the input end of the reducer:
Current Fluctuation Rate: Record the current changes during operation. If the current fluctuation range is within ±10%, it is mostly a constant load; if it is around ±30% and there are low-frequency fluctuations, it is consistent with slight impact characteristics.
Peak factor: Calculates the ratio of the maximum instantaneous current to the rated current. If the coefficient continues to exceed 1.5, or even reaches above 2.0, it must be determined as a strong impact load, and the safety factor of the reducer Selection needs to be rechecked.
