摘要： A fastener includes a threaded circular ring (30) half divided along a plane intersecting a central longitudinal axis. One of the end walls (42) is formed with a truncated conical load-bearing surface that is seated on a truncated conical thrust surface (58) formed on a circular ring of a stress generator. The load bearing and thrust generating surfaces are arranged to present a conjugate pair of truncated conical surfaces to provide a favorable resolution of forces developed by torque applied to jack bolts distributed about an outwardly surrounding cylindrical stress generator body section.

摘要： A compression generator (10) uses a plurality of jackbolts (38) threadedly engaged at a spaced apart relation about a bolt circle in a main core element. The main core element is releasable interlocked by threads, bayonet connection or other form of fasting system with the mounting element forming a fixed part of the mechanical connection. The jackbolts torqued to generate a pushing force in an axial direction for compressing a moveable part of the mechanical connection against a compression seat for forming a mechanical connection between juxtaposition fixed and moveable parts (12,14).

摘要： A high temperature bolting system (16) for clamping steam turbine housings (10) while operating at a temperature of 800 to 1200 degrees F. An elongated fastener shank (20) has a similar coefficient of thermal expansion as the housings sections (12, 14). The shank has a tensile strength several times greater than the housing to maintain a clamping force during thermal excursions, and a much higher creep strength than the clamped parts. A stress generating flange (28) is provided with jackbolts (34) to establish the clamping load at room temperature. A threaded sleeve (54) is interposed between the threads at the end of the shank and the threads of the housing so that the housing threads have a sufficiently large area for withstanding the clamping load. A flanged support ring (64) is mounted at a bolt hole in the flange to support a load bearing area when retrofitting existing housings.

摘要： Jackbolt (20) for a multi jackbolt tensioner embodies a thread construction which tapers from a maximum diameter adjacent to the torque receiving end (22) of the jackbolt (20) when threadedly engaged with a threaded opening in the outer peripheral part of a jackbolt body (38). The threads (26) of the jackbolt have a different thread pitch than the threads (36) in the jackbolt body (38) and the tooth flank of the jackbolt threads (26) form an angle with the tooth flanks of the threads (36) in the jackbolt body (38). By this thread construction, there is formed a helical volume of ever increasing size along the jackbolt commencing at a metal to metal relation at the torque receiving end (22). Stressing of the jackbolt (20) closes the helical volume bringing the threads (26) to a metal to metal load transfer relation. The end (28) of the jackbolt (20) has a protruding central end portion that elastically flattens under stress to reduce torque requirements.

摘要翻译：用于多抽头螺栓张紧器的插销螺栓（20）体现了螺纹结构，该螺纹结构当与插头螺栓的外周部分中的螺纹开口螺纹接合时，从与插头螺栓（20）的扭矩接收端（22）相邻的最大直径逐渐变细，（38）。吊杆的螺纹（26）具有与插头螺栓（38）中的螺纹（36）不同的螺距，并且螺纹螺纹（26）的齿面与螺纹（36）的齿面形成一角度，在吊杆本体（38）中。通过这种螺纹结构，在扭矩接收端（22）处形成从金属到金属关系的起重螺栓尺寸不断增加的螺旋体积。螺栓（20）的应力关闭螺纹体积，使得螺纹（26）具有金属与金属的负载传递关系。吊杆（20）的端部（28）具有突出的中心端部，其在应力下弹性地变平以减小扭矩要求。
