摘要： An expandable washer for use with a fastener to maintain tension in the fastener after connection to a component comprises first and second disks. The first and second disks cooperatively define a channel having a dimension parallel to the expansion axis which decreases from a location remote from to a location closer to the expansion axis. The first and second disks are configured to pass the fastener through them and to the component. The fastener operatively engages the first disk for moving with the first disk and to place the fastener in tension when the fastener is connected to the component. The expandable washer further includes a cam located radially outward from the expansion axis and biased for movement toward the expansion axis to drive the first and second disks apart to maintain the application of force against the fastener.

摘要： The present disclosure relates to fastening collars, multi-piece fasteners, and methods for fastening. A fastening collar comprises a first collar end, a second collar end, and an elongate portion intermediate the first collar end and the second collar end and defining a longitudinal axis of the fastening collar. The elongate portion comprises a first region adjacent the first collar end, extending a first distance along the longitudinal axis; a second region adjacent to the second collar end, extending a second distance along the longitudinal axis, and comprising a flange; and an inner collar surface defining collar cavity extending through the elongate portion from the first collar end to the second collar end. The second collar end extends away from the longitudinal axis of the elongate portion at a first angle offset from an angle perpendicular to the longitudinal axis of the elongate portion.

摘要： A bolt includes a shank having a first end, a second end, a first external thread proximate to the first end, and a second external thread proximate to the second end. The first external thread twists in a first direction, the second external thread twists in a second direction, and the first direction is different from the second direction. The first external thread includes a minor diameter, the second external thread includes a major diameter, and the minor diameter of the first external thread is greater than the major diameter of the second external thread.

摘要： An improved screwed fastening system for railway rails is proposed to allow rail fastening clips to be moved onto and off the rail more easily, facilitating track installation and maintenance. One improvement comprises providing in the screwed fastening system a clip guiding device, for guiding the rail fastening clip whilst it is being driven, which has an asymmetrically-located hole for receiving the screw-threaded shank of a screwbolt. Another improvement comprises providing in the screwed fastening system a rail fastening clip and screwbolt assembly which have inter-engaging driving portions. In each case, rotation of the screwbolt in one direction brings about translational movement of the rail bearing portion of the clip away from the screwbolt, and rotation of the screwbolt in the opposite direction brings about translational movement of the rail bearing portion of the clip towards the screwbolt.

摘要： A method of installing a releasable shade membrane to a shade system is presented. The method comprises installing a tension release system within a structural component of the shade system. The tension release system comprises a threaded member configured to, when actuated, cause a coupling mechanism to move along an axis defined by the threaded member. The method also comprises coupling a shade membrane to the coupling mechanism. The method also comprises actuating the threaded member in a first direction, such that the coupling mechanism moves along the axis in a tensioning direction. The tension release system is configured to release applied tension upon actuation of the threaded member in a second direction, causing the coupling mechanism to move along the axis in a release direction. The release direction is substantially the reverse direction of the tensioning direction.

摘要： Embodiments disclosed herein generally relate to a system and method for tensioning a bolt. The bolt tensioning system may be used with variable length connection members, for example studs, in any one or more of the drilling, subsea, and process industries to couple a first member to a second member. The bolt tensioning system may remain coupled to the first member and the second member, while applying tension to all of the bolts at the same time, rather than having to torque or tension each bolt individually. The bolt system may accurately and uniformly tension all bolts in a single operation to provide reliable connections.

摘要： A torque retention arrangement for a flange bolt connector for use with pipe. The torque retention arrangement a carrier body and a plurality of springs. The carrier body can include a plurality of spring holes equi-spaced around a circumference. A plurality of springs in a vertical stack can be mounted in each of the plurality of spring holes in the carrier. Each spring is in a convex orientation in a pre-torque condition and is in a planar orientation in a post-torque condition.

摘要： A two-piece locking nut assembly for securing a mantle to a head assembly of a cone crusher. The two-piece locking nut assembly includes an inner nut and an outer nut. The inner nut includes a set of axial bores that each receive a jackscrew. Once the locking nut assembly is in position on the head assembly, the series of jackscrews are tightened to exert a force on the mantle that is counteracted by forces through the inner nut and into the head to create a locking force between the locking nut assembly and the head assembly. The outer nut is turned along the inner nut to hold the locking nut assembly in place. Once the outer nut is moved into position, the jackscrews are removed such that the outer nut continues to apply the locking force between the mantle and the head through the locking nut assembly.
