FIELD: mechanics. ^ SUBSTANCE: choke, is assigned for overlapping of openings in structures access to which is only from one side. Choke is implemented with anaxial, relative to choked opening of structure, body, in which it is implemented through hole for clamping bolt, contains clamping bolt, centering element, implemented as a part of body with diametre, equal to diametre of choked opening of structure, herewith opening for clamping bolt relative to axis of choked opening of structure is implemented with excentricity E, value of which is Eëñ0.5-(D-d), where d - diametre of coupling bolt, and maximum remote part of bearing surface of coupling bolt head is at a distance Km from axis of coupling bolt in limits of numerical values (0.5D-E)<RMëñ(0.5*D+E), herewith coupling bolt head on circular arc is not less than 180 not allows material for all thickness of coupling bolt head beyond the diametre d of coupling bolt. ^ EFFECT: reliability enhancement. ^ 3 dwg |
