AI Technical Summary

Technical Problem

Traditional oil-scraping devices lack sufficient centrifugal force to meet the requirements of a wide range of centrifugal force thresholds, requiring repeated operations to achieve the required oil content of the cage, resulting in low oil-scraping efficiency.

Method used

A cage vacuum oil-throwing device was designed. By drawing a vacuum in the sealed working chamber, the oil-throwing adapter shaft is driven by a magnetic fluid sealing device and a high-speed motor to achieve high-speed rotation of the cage under vacuum, thereby improving the centrifugal force reserve capacity and efficiently throwing out the lubricating oil.

Benefits of technology

In a vacuum environment, the cage can reach higher speeds more quickly, significantly increasing centrifugal force, shortening oil slinging time, and improving oil slinging efficiency. It eliminates the need for repeated operations and meets the requirements of a wide range of centrifugal force thresholds.
