Abstract
The utility model discloses an automobile oil seal which comprises an oil seal body; the oil seal body mainly comprises an outer-layer rubber sleeve and an inner-layer metal skeleton; the automobile oil seal is characterized in that the outer edge of the inner-layer metal skeleton is vertical outwards to extend into a plane; and the bottom of the outer-layer rubber sleeve is tightly connected with the plane. The automobile oil seal of the utility model can ensure that a lip surface of the oil seal is vertical to a rotating shaft to effectively avoid sealing failure caused by installation errors, thereby having excellent promotion value.
Description
Technical field
The utility model relates to the seal arrangement technical field, relates to a kind of oil seal structure in particular.
Background technique
Oil sealing is to be used for the mechanical component of oil sealing, and it isolates the parts that need in the transmission part to lubricate and the parts of exerting oneself, and is unlikely to allow oil seepage.Can be divided into various ways and different calls from seal action, characteristics, structure type, working state and the sealing mechanism etc. of oil sealing, but traditionally generally with rotary shaft lip seal on oil sealing, static seal and motive sealing (general to-and-fro motion) with Sealing Sealing.At present; the oil sealing labial surface takes place in installation process through regular meeting and departs from running shaft in automobile oil seal; cause problems such as seal failure because of setup error, for this reason, how to develop a kind of when guaranteeing to install the oil sealing labial surface automobile oil seal vertical with running shaft become people's urgent problem.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, easy for installation, and long service life, the automobile oil seal of good seal performance.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of automobile oil seal, comprise the oil sealing main body, the oil sealing main body mainly is made of outer layer rubber cover and inner layer metal skeleton, it is characterized in that, outwards vertical extension of the outer rim of described inner layer metal skeleton is a plane, and outer layer rubber cover bottom closely is connected with this plane.
As further specifying of such scheme, the lip bottom side of described outer layer rubber cover is provided with caulking groove, the middle part of inner layer metal skeleton is provided with arch support, the outer layer rubber cover is close to the arch support surface, and the inner side edge of arch support is a plane and is flush-mounted in the described caulking groove to the vertical extension of lip direction.
The lip position of described outer layer rubber cover is provided with the leaf tail, and the arranged outside of leaf tail has the spring ditch of mounting spring.
The inboard of described leaf tail is provided with to cut and has a shave, and cuts the below of having a shave and is provided with deflection division, and the inwall of deflection division circumferentially is provided with the return wire that is rearranged by many convex tendons that are obliquely installed.
The below of described deflection division is provided with dust excluder lips, and dust excluder lips is provided with the inclined-plane, and the angle of inclination is the 45-80 degree.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts the vertical plane of extending of oil sealing external diameter, and plane and installation cavity coincide during installation, and the oil sealing labial surface is vertical with running shaft when guaranteeing to install, and effectively prevents the seal failure that causes because of setup error.
