Conical section elastomeric shaft seal

摘要

The seal for rotating or reciprocating shaft applications consists of an elastomeric sealing part and a rigid cylindrical part by which the unit is retained in a housing or on the shaft. The conical surface of the first part meets a concave surface of the second part to form a continuous surface. The elastomeric ring (1) has a sealing face (2) and an outer conical face (3) on which an elastic ring (4) bears. A support cylinder (5) continues the surface (3) with a concave surface (7). Extending legs (8) or cylinder (8') complete the support. The two parts (1, 5) may be inverted so that the support cylinder may fit within a surrounding housing.
