Abstract

The utility model relates to the technical field of sealing, in particular to a lip-shaped sealing ring of a rotary shaft. The lip-shaped sealing ring of the rotary shaft comprises a skeleton and a rubber sealing body wrapped on the inner side of the skeleton, wherein the skeleton is an L-shaped metal skeleton; the rubber sealing body is provided with a blade tail part; a spring groove is formed on the inner side of the blade tail part; a spring body is arranged in the spring groove; and a cutting surface is formed on the other side of the blade tail part. The skeleton of the lip-shaped sealing ring of the rotary shaft is designed on the basis of pure rubber so as to greatly facilitate the assembling of the sealing ring, ensure the assembling and positioning of the seal, avoid the escape or leakage of lubricating oil of an automobile lubricating system, guarantee the sealing effect, prolong the service life of the sealing ring, and meet the using requirement.

Description

Rotary shaft lip seal
Technical field
