Rotation positioning device with long life-time for space applications

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.
