Latest Patents
One of Eiji Funahashi's latest patents is for a wheel bearing and sealing device. This innovative design includes a sealing device positioned between the inner and outer members of the wheel bearing. The sealing device features an elastic member that forms an encoder grid and is mounted on a first annular sealing plate. A second annular sealing plate is equipped with sealing lips. The engagement between the cylindrical wall of the first annular sealing plate and the inner member utilizes an elastic member made from a material different from that of the elastic material. This elastic member can be a rubber-coated layer, resin paint layer, a thin film of adhesive material, or a ring-shaped rubber member. This design effectively prevents any possible ingress of water across the engagement surface of the annular sealing plate, thereby increasing the lifetime of the bearing and eliminating issues related to the separation and displacement of the annular sealing plates. Additionally, the magnetic flux density can be easily secured.
