AI Technical Summary
In existing worm gear reducers, magnets are not very effective at attracting iron filings and are inconvenient to clean, which affects the quality of lubricating oil and the life of the equipment.
A worm gear reducer mechanism is designed, which expands the magnet distribution range by setting a switchable mounting bracket on the oil plug, and facilitates magnet cleaning without removing the oil pan.
It improves the magnet's ability to attract iron filings, simplifies the magnet cleaning process, facilitates lubricant replacement, and extends the equipment's service life.
