装置２８０１の階段状円錐形締結具形状は、スタッドスレッド２８３４と内側スリーブスレッド２８１５との間の螺旋傾斜平面を通る機械的摺動作用によって、スタッド２８３０に引張荷重を生成する。トルク入力装置は、トルクの下で回転を内側スリーブカップリング手段２８１７に加え、一方、外側スリーブ外側スプライン２８２７上のトルクを反作用させて、摺動螺旋ねじ作用を生成する。外側表面２８１２および内面２８２１が実質的に平滑であるとき、外側スリーブ２８２０は、内側スリーブ２８１０が回転する間、静的なままである。トルク入力装置の反作用要素は、カップリング手段２８３３によって、スタッド２８３０の先端２８３２と回転カップリングされる。これは、スタッド２８３０の回転を阻止し、内側スリーブねじ２８１５とスタッドねじ２８３４との間の相対的な摺動動作を可能にする。スタッド並進はトルク入力装置が内側スリーブ２８１０にトルクを継続的に加える一方、外側スリーブ外側スプライン２８２７上で反作用し、カップリング手段２８３３によってスタッド２８３０と回転カップリングされるように、そのような並進に対する抵抗に比例して生じる。 The stepped conical fastener shape of device 2801 produces a tensile load on stud 2830 by mechanical sliding action through a helical inclined plane between stud threads 2834 and inner sleeve threads 2815 . The torque input device applies rotation under torque to the inner sleeve coupling means 2817 while reacting the torque on the outer sleeve outer splines 2827 to create a sliding helical threading action. When outer surface 2812 and inner surface 2821 are substantially smooth, outer sleeve 2820 remains static while inner sleeve 2810 rotates. The reaction element of the torque input device is rotationally coupled with the tip 2832 of stud 2830 by coupling means 2833 . This prevents rotation of stud 2830 and allows relative sliding motion between inner sleeve thread 2815 and stud thread 2834 . Stud translation resists such translation such that the torque input device continuously applies torque to inner sleeve 2810 while reacting on outer sleeve outer spline 2827 and rotationally coupled with stud 2830 by coupling means 2833 . Proportional to resistance.

図２８Ａ～１０の除去された外側（内側スリーブ２８１０）および内側（外側スリーブ２８２０）の円柱状の特徴部の量、寸法、幾何学的形状および間隔に関連する議論は、一般に、図３０Ａ～３０Ｄの除去された外側（第１の結合部材３００３）および内側（第２の結合部材３０１３）の多角形特徴部の量、寸法、幾何学的形状および間隔に適用される。内側スリーブ２８１０と外側スリーブ２８２０との間のインタフェースは円筒状であり、したがって、平滑であり、したがって、相対的回転を可能にすることに留意されたい。しかしながら、第１および第２の連結部材の間の境界面は多角形であり、角度が付けられているので、相対的な回転は不可能であることに留意されたい。 Discussions relating to the amount, size, geometry and spacing of the removed outer (inner sleeve 2810) and inner (outer sleeve 2820) cylindrical features of FIGS. 28A-10 generally refer to FIGS. applied to the amount, size, geometry and spacing of removed outer (first coupling member 3003) and inner (second coupling member 3013) polygon features. Note that the interface between inner sleeve 2810 and outer sleeve 2820 is cylindrical and therefore smooth, thus allowing relative rotation. Note, however, that the interface between the first and second connecting members is polygonal and angled so that relative rotation is not possible.
