Abstract
The utility model discloses a rotating shaft oil seal. The rotating shaft oil seal comprises a framework, a main lip opening and a dustproof lip. The main lip opening is arranged on the inner circumferential end face of an oil seal body. A spring is arranged on the outer side of the main lip opening. The section of the framework comprises a vertical section and a horizontal section. The horizontal section stretches inwards from the middle of the vertical section. The dustproof lip comprises a first dustproof lip body and a second dustproof lip body, wherein the first dustproof lip body is arranged on the inner circumferential end face of the oil seal body, and the second dustproof lip body is arranged on the outer circumferential end face of the oil seal body. Annular sawtooth-shaped pointy teeth are arranged at the front end of the first dustproof lip body. According to the rotating shaft oil seal, the dustproof lip comprises the first dustproof lip body and the second dustproof lip body, wherein the first dustproof lip body is arranged on the inner circumferential end face of the oil seal body, and the second dustproof lip body is arranged on the outer circumferential end face of the oil seal body, and therefore the dual dustproof effect is good. The annular sawtooth-shaped pointy teeth are arranged on the first dustproof lip body, and therefore dust and other impurities difficultly enter lubricating oil.
