[0002] A floating oil seal is a type of mechanical seal, a rotating dynamic sealing device developed to adapt to harsh working environments. This special type of mechanical seal, with its dynamic end-face sealing function, is characterized by easy maintenance, excellent sealing performance, long service life, and a simple structure. It is primarily used in construction machinery and other types of machinery. Its structure primarily consists of a pair of floating seal rings, a rubber ring, and a floating seal seat.

[0003] The existing patent number (CN216382561U) proposes a spiral floating oil seal, which can effectively adapt to the rubber ring. At the same time, the arc-shaped protrusion design makes the connection between it and the cone surface I become arc-shaped, minimizing the wear on the rubber ring. At the same time, a branch port is added to the spiral oil guide groove to allow oil to enter faster. However, the device lacks the wear-resistant and corrosion-resistant functions for the rubber ring, and the rubber ring may be damaged. In response to the above problems, the present invention proposes a double-bevel floating oil seal with excellent sealing effect to facilitate people's use. Utility Model Content
