Latest Patents
Mizuno's latest patents include a bearing device for internal combustion engines. This device features a crankshaft made of steel that has not been subjected to surface hardening. The crankshaft's structure is primarily composed of pearlite, with a pro-eutectoid ferrite fraction of at most 3%. It is processed to achieve a surface roughness Rz of at most 0.8 μm. The bearings used in this device are made from an aluminum bearing alloy bonded to a back plate, containing at least 4 mass % of Si particles. This design effectively suppresses early abrasion and scratches of the crankshaft, ensuring durability comparable to conventional DCI shafts. Another notable patent is the sliding bearing half shell, which features a positioning lug that expands outwardly along the circumference of a half-circular bearing body. This innovative design prevents the failure of the positioning lug due to fatigue caused by cyclic bending stress.
