Abstract

The invention discloses a seal assembly. The seal assembly is characterized by comprising a rubber seal (3) and a dust board, wherein the dust board and the rubber seal are arranged in a separated manner; the rubber seal comprises an inner oil lip and an outer oil lip, the inner oil lip and the outer oil lip are divergent and arranged in a'Y' shape; the outer oil lip (8) is thick and large and is arranged outside; the inner oil lip (9) is small and thin and is arranged inside; and the inner oil lip and the outer oil lip are connected to a rubber seal base (7). The dust board is arranged outside the rubber seal, better dustproof effect can be realized, and the rubber seal can be protected. The invention also discloses a slewing bearing applying the seal assembly. The outer oil lip of the rubber seal clings to the end face of an outer ring of the slewing bearing, and the inner oil lip is clings to an annular slope groove of an outer ring, thus sealing effect is enhanced.

Description

[0001] Technical field [0002] The present invention involves the field of bearing technology, which specifically involves a sealing component and a reincarnation support using the seal component. [0003] Background technique [0004] The existing rotation support is also equipped with seal components, but most of them are ordinary lip -type sealing, a single seal structure, and the dustproof effect of the structure is poor, which affects the service life of the rotary support. [0005] Invention content [0006] The technical problem to be solved by the creation of the present invention is to provide a rotary support component with good sealing effects and long service life. The creation of the present invention also provides a rotary support for using the seal component. [0007] A seal component, including rubber sealing and dustplanes, dustproof plates and rubber sealing split split; the rubber seal includes internal and external oil lips, the two fork setting, which is "Y...
