The invention discloses a gearbox for twin-screw extruders, relating to gearbox technology, including an upper gearbox and a lower gearbox in fitted contact. During operation, the top circulating pump and bottom circulating pump work collaboratively to realize automatic circulating lubrication and improve operational efficiency. The electromagnetic filter plate generates a magnetic field when electrified to separate iron filings and impurities from lubricating oil and ensure oil cleanliness. After filtration, a micro motor drives the linkage plate to move reciprocatingly, pushing adsorbed metal debris into a collection box for automatic cleaning. The fully filtered lubricating oil flows back to the liquid storage tank for recycling, realizing continuous, efficient and clean lubrication with reduced maintenance workload.
