More Information
Summary:The utility model relates to a magnetic encoder provided with an oil control ring and a magnet part, wherein the oil control ring is provided with a cylinder part and a flange part, the cylinder part can be externally embedded on a rotating body, the flange part is formed through outward extension in the direction of a radius from the cylinder part, the magnet part is roughly shaped as a circular ring and is mounted on the outer side face of the flange part of the oil control ring, the oil control ring is made of a ferromagnetic material, and the magnet part is formed by a rubber magnet material or a plastic magnet material. When the axial thickness of a part, starting from the outer side face of the flange part, of the magnet part is set as T1 and the axial thickness of the flange part is set as T2, a condition of T2<T1 is satisfied.
