Swage Rivet to Fix Shafts

       Disclosed is a mechanical means of fastening a fixed
shaft to a cover structure using cold shrinking and swage
technologies.

      Most shafts are fastened by means of screws and nuts. The
sealing is done in different ways, such as plastic washers, RTV and
tape.  In using a swage rivet, sealing means of these kinds are not
needed.

      The swage rivet is cold shrunk into the cover structure
providing an airtight seal (see Fig. 1).  The cover is then
positioned over the shaft with the rivet tendon fitting inside the
through hole in the shaft.  A tool is placed from the bottom up
through the hole in the shaft to support the rivet as the ball is
forced into the rivet from the other side (see Fig. 2).  As the ball
is forced down the hole in the rivet, it expands the walls of the
rivet against the walls of the shaft, creating an airtight seal and
thereby fixing the shaft to the cover structure.
