Abstract

The invention discloses an oil seal, which includes an oil lip and a steel plate framework (3), wherein the steel plate framework is L-shaped, a connection base (4) part of the oil lip is arranged and clung to the outer side of the steel plate framework, the connection base is connected with an oil lip section (8), upper leftwards and upper rightwards bulges are arranged at the two ends of the oil lip section, the upper leftwards bulges is an outer oil lip (5), and the upper rightwards bulge is an inner oil lip (6). The outer oil lip plays the dustproof function better; and the inner oil lip and a spring ring play the function of oil sealing. The invention further provides a pivoting support employing the oil seal.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to an oil seal and a slewing bearing using the oil seal. [0002] Background technique [0003] The existing slewing bearings are also equipped with oil seals, but most of them are ordinary lip seals with a single sealing structure, and this structure cannot effectively prevent the leakage of lubricating grease, and the dustproof effect is poor, thus affecting the service life of the slewing bearings. [0004] Contents of the invention [0005] The technical problem to be solved by the invention is to provide an oil seal with good sealing effect and long service life, and the invention also provides a slewing bearing using the oil seal. [0006] An oil seal, including an oil lip and a steel plate frame, the steel plate frame is set in an L-shape, and the connecting base part of the oil lip is arranged on the outside of the steel plate frame, the connecting base is connected to ...
