A fiber rotary joint
is used to help rotate the fiber with no mechanical stress.
The 2nd-stage targeting device consists of three magnetic pins with rotary joints
, a transparent baseboard with three conductive rings, and an indicator.
To analyze the effect of introducing a right angle bend and rotary joint
into the monopole antenna-feed network, Sn measurements were collected (in an 80: 20 glycerine: water mixture) using an Agilent E5071A network analyzer for (a) the clinical imaging system's traditional encapsulated monopoles (antenna_1 and antenna_2, resp.), (b) the straight monopoles prior to bending (antenna_3 and antenna_4, resp.), (c) the bent monopoles (antenna_5 and antenna_6, resp.), and (d) the bent monopoles incorporating the rotary joint
(antenna_7 and antenna_8, resp.) (Figure 4).
Benefits of the SX rotary joint
are said to include positive sealing; increased life and reliability; extended seal life and reduced maintenance; self-aligning seal with longer life; improved joint and syphon support; and application flexibility.
The basics of pressure rotary joints
A pressure rotary joint
consists of one or two carbon bearings, a carbon graphite seal with a spherical sealing face and a spring that keeps the seals together at zero pressure (figure 2).
The energy from the spinning reflector/feed antenna subsystem is routed through a DC to an 18 GHz coaxial rotary joint
to the base of the pedestal.
The fluid enters from the one end of the roll through a rotary joint
and is conveyed to the hole just under the surface where it travels the face of the roll, flows to the next hole and returns to the opposite end where it flows to the center of the roll and is siphoned out.
