To prevent oil leakage from bearing housings, the following measures can be taken: If the bearing housing does not have an oil return groove, it should be machined in a timely manner to ensure smooth oil return;
If the oil return groove is blocked, it should be cleaned immediately to maintain a clear circuit; check the installation position of the oil return groove to ensure it is located at the lowest point of the housing; strictly control the oil level to avoid exceeding the maximum mark, ideally maintaining it in the middle position; add an oil baffle ring to reduce oil splashing; check the vent plug for blockage, and if blocked, clear it promptly to prevent pressure buildup inside the housing from causing leakage.
