FOUR CHANNEL WAVEGUIDE ROTARY JOINT FOR HIGH POWER APPLICATION

摘要

The invented rotary joint comprises four E-plane rectangular-cross section waveguides (1, 2, 3, 4) each cut transversely into two sections at the cross section thereof where the current density in the wall is zero, two cover plates (5, 7) of which one (5) is stationary and the other (7) is rotatable, one broad wall divided transversely into two half sections (14, 15) of which half section (14) having a spindle (16) at the centre thereof is attached parallelly and co-axially to the stationary cover plate (5) holding one cut-section each of the four waveguides mounted cocentrically thereon, and the other half section (15) having a single bearing (8) at the centre is attached parallelly and co-axially to the rotatable cover plate (7) holding the other cut-section each of the four waveguides mounted cocentrically thereon, the said spindle (16) and bearing (8) being engaged co-operatingly with each other.
