The present invention discloses a lubrication oil circuit for a co-rotating parallel twin-screw extruder gear reducer, comprising a reducer housing, an intermediate housing, and an output housing. The reducer housing features a rear oil inlet, a top oil inlet, and a bottom oil outlet. The intermediate housing has a top oil inlet. The output housing incorporates a top oil inlet and a side oil return port. The bottom oil outlet connects to a coarse lubricating oil filter via a ball valve. The coarse lubricating oil filter connects to a lubricating oil pump. The lubricating oil pump connects to a three-way fitting III. The three-way fitting III connects to a three-way fitting IV and a fine lubricating oil filter. The three-way fitting IV connects to a shock-resistant oil pressure gauge and a one-way check valve. which connects to the side return port. The fine lubricating oil filter connects to a plate heat exchanger, which links to each inlet port via separate oil distribution lines. This invention enables effective lubricating oil cooling, facilitates immediate inspection and assessment of oil circuit conditions, and prevents damage to gearbox gears and bearings.
