Abstract
The utility model discloses an oil seal which comprises a framework. The outer side of the framework is sleeved with a supporting ring. The upper end and the lower end of the framework are respectively provided with an inward flanging. An inward supporting edge is arranged in the middle of the framework and provided with a rubber body. The periphery of the rubber body is sleeved with an extension spring. An annular cavity is formed inside the rubber body. A nylon tube is placed in the annular cavity. The inner wall of the rubber body is in a sawtooth shape; the bottom of the rubber body is provided with a sealing lip edge. The flanging at the upper end of the framework and the flanging at the lower end of the framework are respectively provided with a dust-proof lip edge. The outer wall of the framework is provided with protrusions. The supporting ring is provided with grooves corresponding to the protrusions. The framework, the supporting ring, the rubber body, the spring, the nylon tube, the dust-proof lip edges and the sealing lip edge are all vulcanized into a whole. As the upper end and the lower end of the framework are respectively provided with one inward flanging, and each flanging is provided with one dust-proof lip edge, the dust-proof effect is good; the nylon tube is arranged in the rubber body, so that the intensity of the rubber body is enhanced, and the service life is prolonged; the inner wall of the rubber body is in the sawtooth shape, so that the sealing effect is improved.
