A rotary mechanism comprises a fastener and a tone wheel. The tone wheel comprises a first radial flange, a second radial flange, a first target, and a second target. The first and second targets mounted respectively to the first and second radial flanges to be sensed by a sensor. Each of the first radial flange and the second radial flange comprises a plurality of mounting points, the plurality of mounting points of the first radial flange and the second radial flange provided for adjustment of a diameter of the tone wheel. The fastener is provided to mount the first radial flange and the second radial flange to a shaft at a selected mounting point among the plurality of mounting points of each of the first radial flange and the second radial flange to set the diameter of the tone wheel. An associated method is disclosed.

A quick release connecting assembly is provided. The quick release connecting assembly includes a first connector and a second connector, wherein the first connector includes an upper fixed plate, a middle portion of the upper fixed plate is connected to a connecting column, and a clamping slot is formed in a middle portion of the connecting column; and the second connector includes a lower fixed plate, a middle portion of the lower fixed plate is connected to a connecting pipe matched with the connecting column, a side surface of the connecting pipe is connected to a side pipe communicating with the connecting pipe, and a bolt column is arranged in the side pipe. The connecting column of the first connector and the bolt column of the second connector are clamped, such that the quick release connecting assembly is simple in integral structure and convenient to disassemble and assemble.

A coupling mechanism securing a first object having a well to a second object having a lug, including a shuttle movable within the lug, a resilient biasing means biasing the shuttle away from a base of the well when the lug is inserted, and locking elements movable radially in the lug between a retracted position and an extended position. Each locking element moves from the retracted position and retains in the extended position by a surface profile of the shuttle. The coupling mechanism includes a movable stop having: a first position in which movement of the shuttle is limited so the locking elements interact with the surface profile, and a second position in which movement of the shuttle is extended to cause the locking elements to interact with another surface profile of the shuttle, moving the locking elements from their extended position to their retracted position.

The invention relates to an assembly for a turbomachine with a longitudinal axis comprising a first annular wall (24), panels (38) being arranged around the longitudinal axis (A) and extending radially opposite said first annular wall (24) so as to form a flow surface for a flow of air, each panel (38) being secured to the first annular wall (24) by at least one fixing member (72) passing through an orifice in the panel (38) and secured to the first annular wall (24) by means of a sleeve and a stud forming a spacer.

A fastener having two branches extending on either side of a median plane, each branch carrying a tongue, the tongues defining between them a throat between the two branches. When the fastener is reversed with respect to another identical fastener, their respective median planes forming a non-zero angle between them, one branch of the fastener having its distal portion in contact with at least one of the two tongues of the other fastener and its outer face in contact with an inner face of one branch of the other fastener, the distal portion of the other branch of the fastener is substantially in contact with the distal portion of the other branch of the other fastener.

A spacer-locator with integrated locator pins and spacer tabs for use in joining applications. The spacer-locator provides consistent and accurate spacing between mating surfaces and the locator pins provide enhanced location control of the joining components while providing a mechanical advantage to the shear strength at the joint. Also, a spacer-locator for joining at least two objects along mating surfaces, the spacer-locator constraining at least two degrees of freedom for the objects to be joined.

A fastener structure used to arrange a second object on a first object and a method of use of the fastener structure includes an engaging portion, a direction limiting portion, and an assembly portion. The engaging portion is for engaging to a second object. The direction limiting portion is connected to the engaging portion and is for limiting a movement direction of the second object engaged with the engaging portion. The assembly portion is for assembling to the first object.

A structural assembly including a first member having an external side and an internal side, the first member defining a first member through-bore, a second member having an external side and an internal side, the second member defining a second member through-bore aligned with the first member through-bore, and a mechanical fastening system including a bushing at least partially received in the first member through-bore, the bushing defining a bushing through-bore and including a flange, wherein the flange is positioned in a gap between the internal side of the first member and the external side of the second member, a nut plate connected to the internal side of the second member, the nut plate defining a clearance bore aligned with the second member through-bore and the bushing through-bore, the nut plate including a nut, and a bolt extending through the bushing through-bore and into threaded engagement with the nut.

In various embodiments, a mounting system may comprise a downslope rail, an upslope rail, a first clamp and a second clamp. The downslope rail may have a first profile and comprising a downslope face and an upslope shelf. The upslope rail may have a second profile and comprising a downslope shelf and an upslope face. The first clamp may be configured to engage the downslope face and accept the installation of a first end of a solar panel. The second clamp may be configured to engage the upslope face and retain a second end of the solar panel against a downslope shelf

A fastener for securing a panel to a substructure includes a flange having a bore, a base disposed under the flange and having a post extending upwardly from the base, the post having a retaining member at an upper portion thereof, and at least one flexible hinge resiliently connecting the base and the flange such that when the base is pushed toward the flange, the post with the retaining member passes through the bore adapted to engage with other member. The flange further includes flexible walls formed around the bore and extending outward with retaining clips formed at respective leading ends thereof. The flexible walls bend towards the bore when pressed into the bore.
