摘要： A method of fabricating a fluid seal for sealing a relatively rotatable member, wherein the fluid seal has an elastomeric sealing member bonded to a PTFE insert. A wafer of PTFE material has a body portion and an end portion of a greater thickness than the body portion. The wafer is placed in a mold cavity with one side of the wafer opposed to a surface portion of the mold cavity. Elastomeric material is forced into the mold cavity to form a molded preform of the elastomeric sealing member and bond the preform to an opposite side of the wafer. The molded preform and bonded wafer are removed from the mold cavity. The end portion of the wafer and an end portion of the preform are trimmed to form the fluid seal.

摘要： A shaft seal for forming a dynamic seal along an axially extending annular running surface and method of installation thereof is provided. The shaft seal has a mounting portion configured to be connected to a stationary housing and a seal lip having an annular sealing surface extending between an oil side end and an air side end of the seal lip. The sealing surface is configured to extend axially along a shaft running surface. An annular bridge portion connects the seal lip to the mounting portion. A plurality of webs extend generally radially between the bridge portion and the mounting portion to prevent the seal lip from being inadvertently unfolded during installation or while in use. An annulus can be used to install the shaft seal into a housing and about a shaft without the need for secondary operations.

摘要翻译： 提供了一种用于沿轴向延伸的环形运行表面形成动态密封件的轴密封件及其安装方法。 轴密封件具有安装部分，其被构造成连接到固定壳体和密封唇缘，该密封唇缘具有在密封唇的油侧端部和空气侧端部之间延伸的环形密封表面。 密封表面构造成沿着轴运行表面轴向延伸。 环形桥部分将密封唇连接到安装部分。 多个腹板在桥接部分和安装部分之间大致径向地延伸，以防止密封唇在安装期间或在使用时不经意地展开。 可以使用环形件将轴密封件安装到壳体中并且围绕轴安装，而不需要二次操作。
