Equipment for moving shaft parts, with inner and outer arms

摘要

The outer arm (2) touching the exterior of the shaft part (S) wall, and inner arm (3) fitting into the interior of the shaft part are joined by a support arm (4). A lever arm (5) rotarily linked to the inner arm has one end supported on the inside of the shaft wall, while the other end is rotarily linked to one end of an element (10) rotarily joined to a pressure element (12) on a pivot point (11). The pressure element is rotarily linked to one end of a tie(15). the angle between the longitudinal axis of the tie and that of the pressure bar (12) is restricted by a thrust piece (17).
