Mobile element e.g. antenna, rotational positioning device for space equipment guiding system, has stop attached to one of rings so that relative rotation of rings is angularly limited and whose angular positioning on ring is adjustable

摘要

The device has a circular crown (1) attached to a fixed part (10) of a space equipment and a connection handle (6) actuating a pipe part (11) of the equipment. The handle is connected to a ring of a ball or roller bearing. The crown is connected to a ring (3) of the bearing in an elastic manner in rotation around an axis of the bearing. A stop (5) is attached in a rigid manner to the former ring such that relative rotation of the rings of the bearing is angularly limited. Angular positioning of the stop on the former ring is adjustable.
