MEMBER FOR CONTROL OF PRELIMINARY TENSION IN THREADED ANCHORS

摘要

FIELD: mechanical engineering. SUBSTANCE: member consists of pressing ring 12 and stretching ring 13. The axial preliminary tension, which is exerted by tightening for securing nut 6, results in expansion of stretching ring 13 with pressure ring 12 until nut 6 abuts against stretching ring 13. EFFECT: improved accuracy of control. 1 dwg
