AI Technical Summary
Existing bearing housings cannot effectively utilize thin oil lubrication systems, resulting in high thin oil fluidity, oil film rupture, uneven distribution, and susceptibility to corrosion, thus affecting the bearing's operating condition and lifespan.
A directional oil spray nozzle is installed inside the bearing housing to spray thin oil directly onto the bottom of the bearing mounting chamber to form an oil reservoir. The lubrication status is monitored through an observation port. Combined with the oil return channel and air filter, the thin oil is ensured to circulate and prevent corrosion.
This achieves uniform distribution and effective lubrication of the thin oil, extends the service life of the bearing, and ensures the reliability and safety of the lubrication system.
