CLAMP BELT TYPE INTERMODULE CONNECTORS
DESCIPTION:
• For this design the modules vacuum vessels are
of the same diameter and are assembled with
butt-weld machined flanges.
• The flanges edges are 20 degree tapered at both
sides with grooves machined on the facing sides
to hold elastomer seals.
• Chain like segments are linked on 3 section, the
sections wrap around the flanges and are
fastened to each other by hinged tangential
tightening bolts.
CLAMP SEGMENT DETAIL
• The segments are
machined also with 20
degree tapered channels
that match the tapered
edges of the flanges.
• Prior to assemble the
clamp belt, elastomer
seals and a bellow ring
are inserted between
the flanges
ASSEMBLY
• During the assembly, the
meddle wedge of the clamp
segment spreads the bellow
ring leaves apart over the
the flanges tapered
surfaces, compressing the
seals and protecting them
from the wedge friction
during the insertion, the
below ring completes the
vacuum enclosure
LINK SECTION DETAIL
• The link pieces
between the clamp
segments also extend
into the bellow ring to
insure continuous
compression of the
seals and to reduce
the cross section of
the bellow supporting
the MICE vacuum.
FUNCTIONAL FEATURES (attractive)
• It is evident that for experiments change over
operations it reduces labor time by an order of
magnitude.
• Industrial tolerances for construction and
assembly are accommodated by the flexibility
provided with the hinged link connections of the
belt components.
• The configuration of the wedging/retaining
segments, provide support against the axial
magnetic forces in both directions (pending final
calculations)
DESIGN IMPROVEMENTS
• Increasing the number of sections will:
a) facilitate handling the section by the reduction
of weight, in the current design about 90
Lbs./section
b) will increase the bellow/seals contact,
c) will reduce the bellow unsupported area
increasing the pressure vessel strength to
support vacuum
d) gain lateral flexibility for better adaptation of
construction tolerances (less cost)
