ABSTRACT:
A remote waveguide flange clamp system (10, 11) detachably connects a first waveguide section (20) to a second waveguide section (30, 37). System (10, 11) is controlled remotely by a controller (60). A pair of elongated clamping levers (40) is mounted pivotally to pins (42) on bracket arms (39) of section (30, 37). Levers (40) rotate about pins (42) when a motor assembly (51) moves driving ends (47) of levers (40) outwardly or inwardly relative to section (30, 37). When ends (47) move outwardly, clamping ends (44) of levers (40) apply a compressive force to flanges (22, 32) of sections (20, 30) to provide a gasketed seal (80) inhibiting RF leakage therebetween. Assembly (51) includes a torque sensor (66) for continuously applying current to a motor (50) in assembly (51) until sensor (66) measures current substantially equaling a predefined value. When sensor (66) measures current substantially equaling the value, a fail-safe brake mechanism (56) is engaged to prevent further rotation of a shaft (52) in motor (50).
