Abstract
A seal for a generator stator end winding seals the gap between the annular air shield and a radially inner surface of the stator end winding. The seal includes a first flat piece layer formed of a flexible rubber material and having an inner diameter side and an outer diameter side. A plurality of first radial slits are formed across the outer diameter side. A second flat piece layer is disposed in a layered configuration with the first flat piece layer. The second flat piece layer is formed of the same flexible rubber material. A plurality of second radial slits are formed across the outer diameter side of the second flat piece layer and are offset from the first radial slits in the layered configuration. The seal is secured in a radial groove formed in an end of the air shield by a locking dowel and/or glue. With this arrangement, a reliable seal is configured that is inexpensive to manufacture and easy to install.
