Abstract
The utility model relates to a combined magnetic induction oil seal and belongs to the technical field of magnetic induction oil seal structures. The combined magnetic induction oil seal comprises a first framework, a second framework and a third framework, wherein the axial section of the first framework is a leftward-reversed-L type, and the axial section of the third framework is leftward-reversed-T-type. The third framework is erected above the first framework and the second framework. A first seal body and a second seal body completely coat the first framework and the second framework respectively. A third seal body with the leftward-reversed-T type axial section completely coats the third framework. The leftward-reversed-T type vertical outside surface of the third seal body is a magnetization surface, and a magnetic induction area is arranged on the magnetization surface and used for inducing a digital signal. The magnetic induction area comprises magnetic areas and nonmagnetic areas, wherein the magnetic areas and the nonmagnetic areas are evenly arrayed at intervals. The combined magnetic induction oil seal is reasonable in structure design, low in cost, light in weight and good in seal effect and meanwhile has the function of a gear ring.
