摘要： A method of establishing and checking the axial preload in a tightening portion (34) of at least one shank of the screw or stud type (4). The establishing of the preload involves a step of tensioning an extension portion (33) of the shank (4) comprising the tightening portion (34) using a shank (4) gripper member (9) and a tensioner (6). The checking method involves a step in which, prior to establishing the preload, the tensioner is brought into a rest configuration and the gripper member (9) is brought into contact with the tensioner (6) in said rest configuration, and a step in which, having established the preload, the tensioner is returned to said rest configuration, and the tensioner in said rest configuration is pressed toward one of the ends of the extension portion (33) and the difference between the initial length (Liθ) and the final length (Lfθ) of the extension portion (33) is compared against a threshold.

摘要： Described herein are fasteners and devices for securing together several components so that the load applied to the components is constant or nearly constant. The fasteners described herein include a hyperelastic member having first end to which a first retainer is coupled and a second end to which a second retainer is coupled. The retainers are configured to contact the structures being fastened and transfer the load from the structures to the hyperelastic member. The hyperelastic member may be an elongate shaft (e.g., a rod, cylinder, strut, etc.), and is a shape memory alloy that is typically fabricated as a single crystal.

摘要： The present invention consists of a connection, having an anchored, elongated tension member, a fastening member attached to the elongated tension member, a resisting member that receives the elongated tension member and an expansion device that receives the elongated tension member there through and is compressively loaded between the fastening member and the resisting member by operation of the fastening member on the elongated tension member. The expansion device is formed with a sleeve. First and second bearing members are received in the central aperture of the surrounding sleeve and operatively connected to the surrounding sleeve. At least one of the bearing members is threadably connected to the sleeve. This bearing member can rotate in relation to the surrounding sleeve. A torsion spring connects the first and second bearing members and is located within the surrounding sleeve. The torsion spring biases the first and second members in opposite rotational directions such that at least one of the bearing members is forced to rotate along the thread of the surrounding sleeve away from the other bearing member and out of the surrounding sleeve.

摘要： A locking fastener assembly comprising a fastener having a shaft (12) and a head (14 or 114) and first threads (16) for placing the shaft (12) in tension to clamp a part (18). A threaded washer (20) has second threads (22) for disposition between the head (14 or 114) and the part (18). A torsion spring (24) reacts between the head (14 or 114) and the washer (20) for urging the head (14 or 114) and the washer (20) to rotate in opposite directions. The assembly is characterized by the first and second threads (22) being of different pitches and in the same helical direction whereby the torsion spring (24) continually rotates the washer (20) to maintain a pre-load on the shaft (12). To assemble the components, the hex head (14 or 114) is first torsionally loaded against the washer (20) utilizing the torsional spring (24) such that the components would rotate apart if the pre-load was removed. The hex head (14 or 114) and washer (20) are of the same polygonal (hexagonal) shape and are rotated together with a conventional socket type wrench disposed over both at the same time. The locking fastener assembly is then tightened as the head (14 or 114) and washer (20) are rotated together or in unison to the desired torque.
摘要翻译：一种锁定紧固件组件，包括具有轴（12）和头部（14或114）的紧固件和用于将所述轴（12）放置在张力中以夹紧部件（18）的第一螺纹（16）。螺纹垫圈（20）具有用于设置在头部（14或114）和部件（18）之间的第二螺纹（22）。扭簧（24）在头部（14或114）和垫圈（20）之间起作用，用于推动头部（14或114）和垫圈（20）沿相反的方向旋转。组件的特征在于第一和第二螺纹（22）具有不同的间距并且在相同的螺旋方向上，由此扭簧（24）使垫圈（20）连续地旋转以在轴（12）上保持预加载。为了组装部件，利用扭转弹簧（24），六角头（14或114）首先被扭转地装在垫圈（20）上，使得如果预加载被移除，部件将旋转分开。六角头（14或114）和垫圈（20）具有相同的多边形（六边形）形状，并与同时布置在两者上的常规插座式扳手一起旋转。然后当头部（14或114）和垫圈（20）一起旋转或一致地旋转到期望的扭矩时，锁定紧固件组件被紧固。

摘要： An assembly arrangement includes: an assembly element defining a mounting hole therein; and a cuff inserted into the mounting hole in a vibration-damping manner, the cuff being made of an elastic rubber material and defining a through hole therein. The cuff further includes a cuff neck resting in the mounting hole and defining, over an entire length thereof, an outer circumferential surface extending essentially along a longitudinal axis of the cuff, and a fastening region having an inner wall which protrudes radially inwardly into the through hole, the fastening region extending over a portion of a circumference of the through hole. The assembly arrangement further includes: an assembly sleeve inserted into the through hole and including a jacket having a circumferential configuration such that when the assembly sleeve passes through the fastening region of the cuff, it widens the inner walls of the fastening region in a radial direction thereby fastening the cuff and the assembly sleeve in the mounting hole; and a screw. The screw includes a screw shaft inserted into the assembly sleeve and a screw head adjacent the screw shaft, wherein the cuff is configured such that it is acted upon in a tightening direction of the screw by at least one of the screw head and an annular collar of the assembly sleeve.
