High wear resistance floating oil seals

2020-08-03 14:31:25
The floating oil seal ring with high wear resistance, including the oil seal ring body and the groove opened on the oil seal ring body for accommodating the O-shaped rubber seal ring, is characterized in that: the upper part of the working surface of the oil seal ring body is sprayed with metal wear resistance Layer, a first slope surface is opened under the metal wear-resistant layer, the angle between the first slope surface and the working surface is a (44°-46°), a second slope surface is opened below the first slope surface, and the second slope surface The angle between the slope surface and the working surface is b (4°-6°), the upper end of the first slope surface is connected to the lower end of the metal wear-resistant layer, the lower end of the first slope surface is connected to the upper end of the second slope surface, and the lower end of the second slope surface extends to the oil seal The lower surface of the ring body.


The floating oil seal ring is made of wear-resistant metal powder with better wear-resistant performance. The wear-resistant metal powder is sprayed into the metal wear-resistant layer of the friction contact surface of the oil seal ring by supersonic flame spraying. The metal wear-resistant layer forms the oil seal bright band. Greatly extend the wear-resistant time and increase the service life of the product. The working surface is equipped with two slope surfaces, and the formed oil inlet can ensure the supply of lubricating oil to the frictional bonding ring surface, preventing dry grinding between the bonding surfaces of the oil seal ring , Enhance the oil sealing effect and service life.
