    摘要： A coupling device provides a pre-tensioned coupling between a first member and a second member. The members are arranged to define a sealed compartment. A piston is housed within the compartment and is translated between the first member and the second member. A first ratchet lock is mounted within the second member and on translation of the piston, the first ratchet lock engages with the piston. A second ratchet is mounted within the second member and, on translation of the piston into the second member, the piston engages with the ratchet. The second ratchet is mounted on a piston, and translation of the second ratchet on the piston applies a tensile force to the first piston to tension or pre-tension the piston. As the ratchets substantially prevent reverse movement of the piston, the tensile force is retained.

    摘要： A fastener system and method of inserting it, that includes a screw or bolt having two interleaved helical threads, which brackets or forms a groove for a helicoil. The helicoil expands and torques by various means to maintain hold and purchase between the screw coil combination and the substrate into which the screw and helicoil are inserted even when the substrate recedes a significant distance from the screw and helicoil combination. The fastener system includes means for latching the tilt of the coil so as to minimize the constraining forces and optimize the motion of the helicoil, that results in the screw or bolt being pushed into the substrate. The fastener may be actuated after it has been partly or completely turned into the substrate.

    摘要： An internal combustion engine connecting rod is designed with bolts having a minimum required strength. A strength safety factor Sfa is calculated based on an axial strength limit load FX of the bolt and the maximum load FB to be born by the bolt due to a piston inertia force (Sfa=FX/FB) acting on the connecting rod. A mating surface separation safety factor Sfb is calculated based on the tensile load (FB−FC) resulting from the piston inertia force and the load FE carried by the bolts at a mating surface separation limit, i.e., the maximum bolt load FE at which the connecting rod main body and the cap remain in contact without separating (Sfb=FE/(FB−FC)). The mating surface separation safety factor Sfb of the connecting rod is set to be equal to or larger than the strength safety factor Sfa of the bolts (Sfb≧Sfa).

    摘要： A hydraulic nut having a first part connected around the first end of a fixing member the first part having an annular recess which opens to receive a second part forming an annular member which fits within the annular recess, wherein a pressurized medium chamber is defined between the second part and the annular recess. The second part has an annular portion which extends longitudinally away from the first part. The annular portion has an outer surface which is spaced radially inwardly to form a locking part recess. A locking part is placed within the locking part recess, and has an inner diameter which is threadedly engaged with the second part outer surface. The locking part has a surface facing the first part first surface, and movable by the threaded engagement with the second part to an abutment with the first part first surface.

    摘要： A fastening bolt fastens flanges between a bolt head and a nut attached on the threaded portion of the shaft via spherical washers. The fastening bolt has a cavity formed within the shaft. By application of pressure in the cavity with a hydraulic fluid supplied through a hydraulic pressure port in a plug, the shaft is extended and the fastening bolt becomes unfastened condition. In the unfastened condition, a gap is created between flange and nut, and the nut and the fastening bolt are free to rotate each other, therefore, the nut can be removed easily by hand from the fastening bolt, even the bolt is large in size. The fastening force is adjustable by the width of the gap before releasing hydraulic pressure in the cavity. By releasing hydraulic pressure in the cavity, the fastened condition is obtained. Conversion between fastened condition and unfastened condition can be made quickly and easily.

    摘要翻译： 紧固螺栓通过球形垫圈将法兰紧固在螺栓头和连接在轴的螺纹部分上的螺母之间。 紧固螺栓具有形成在轴内的空腔。 通过在通过插头中的液压端口供应的液压流体在腔中施加压力，轴被延伸并且紧固螺栓变得松开状态。 在松开状态下，法兰和螺母之间产生间隙，螺母和紧固螺栓自由旋转，因此螺母可以用手从紧固螺栓上轻松取下，即使螺栓尺寸较大 。 在释放空腔内的液压之前，紧固力可以通过间隙的宽度来调节。 通过释放空腔中的液压，获得紧固状态。 紧固状态和松开状态之间的转换可以快速方便地进行。
