The normal oil level of YCJ112-4.6-15 reducer (horizontal, gear reduction motor) can be judged in two situations according to its structure and general standards:
1. With transparent oil level window (oil mirror)
Normal range: The oil level is between the MIN (lower limit) and MAX (upper limit) of the oil window.
Recommended position: Upper middle (about 2/3), which can not only ensure sufficient lubrication of gears and bearings, but also avoid stirring heat and oil leakage.
Inspection timing: Observe after stopping the machine to cool down to avoid inaccurate readings caused by splashing during operation.
2. With oil level plug (without oil window)
Remove the oil level screw plug on the side. If the oil level is flush with the lower edge of the screw plug hole, and the oil can be seen but does not flow out, it is normal.
No oil: lack of oil; large amount of outflow: the oil level is too high.
3. General principles (common to YCJ series)
The oil level must not be lower than the lower limit (lack of oil, dry grinding, rapid temperature rise), and not higher than the upper limit (large stirring resistance, high oil temperature, oil seal leakage).
For horizontal installation, the center is preferred; for vertical installation, it can be slightly higher.
