ROTARY SUPPORT Russian patent published in 2009 - IPC H01Q3/08 

FIELD: mechanical engineering.

SUBSTANCE: rotary support is provided for orientation of antenna' system by azimuth and elevation bearing, but can be also used in robotics for manipulator rotating in different planes. Rotary support is implemented in the form of vertical column, external cylindrical rotary body (5) which is put with ability of rotation on immobile post support (1). Motor (14) of azimuthal rotating actuator is located in post support (1), and planetary gearbox (13) is located in the bottom part (5a) of rotary body (5). Outlet crown wheel (21) of reducer (13) is implemented on internal surface of rotary body (5). On the outside on rotary' body (5) it is installed axis (8) of rotation in elevation bearing with rotary platform (10). Slewing mechanism in elevation bearing is implemented in the form of toggle (33) on output drive shaft, cojointed to spherical linkage (34 and 36) and tension bar (35) with rotating platform (10), with formation of arm L about the axis (8), that provides usage in elevation bearing drive planetary gearbox, which other things being equal allows the least dimension and mass. Planetary gearbox (22) swing actuator elevation bearing is located in the top part (56) of rotary body, where with rotation ability it is put - carrier, formed by discs (25 and 26). Disc (25) is output member of reducer (22).

EFFECT: compactness increasing of structure, major details of which are common for two and more units.
