Abstract: Disclosed is an assembly for a gas turbine engine, the assembly includes: a spinner or nosecone comprising a threaded rear portion, an engine structure comprising a threaded front portion, the nosecone being threadingly connected to the engine structure, wherein rotation of the spinner or nosecone about the engine structure in a first direction secures the spinner or nosecone to the engine structure and rotation of the spinner or nosecone about the engine structure in a second direction releases the spinner or nosecone from the engine structure; and a lock ring slidingly connected to the engine structure to slide between: a forward position to engage the spinner or nosecone and block rotation of the spinner or nosecone in the second direction, and a rearward position, where the lock ring is spaced from the spinner or nosecone.

Abstract: A bearing structure for a shaft includes a shaft on which a male thread section is formed and a concave section recessed inside in a radial direction is partially formed in a circumferential direction thereof, a cylindrical holder in which the shaft is disposed, a bearing attached between the shaft and the holder and configured to rotatably support the shaft at an opening side thereof at which the holder is open, a thread engagement member having a female thread section threadedly engaged with the male thread section and a flat surface section crossing the circumferential direction of the shaft and formed on an outer circumference thereof, and coaxially threadedly fastened to the shaft from the opening side, and a locking member having a convex section fitted into the concave section and an engaging section engaged with the flat surface section, and partially locked to the shaft and the thread engagement member.

Abstract: A nut and washer assembly includes a washer unit that is coupled to a nut. The washer unit includes a housing and a washer that is disposed within a sleeve on an inner surface of the housing such that the washer is inseparable from and axially rotatable with respect to the housing. The housing is attached to the nut such that the washer captured within the housing of the washer unit and the nut operate as a single unit.

Abstract: An implant includes an elongate threaded portion defining a first central longitudinal axis and a groove. The groove defines a second longitudinal central axis that extends in the same direction as the first central longitudinal axis. A blade portion extends from the elongate threaded portion and has a taper terminating at a point.

Abstract: A connector bolt for securing an oil cooler to an engine block is made of first and second telescopic pieces. The bolt can be made in different lengths by adjusting the telescopic position of the first and second pieces. The length is fixed by securing the relative positions of the first and second pieces.

Abstract: A compressibly resilient strip is retainably disposed in an axial slot in a threaded shank which is advanced through a bore in a plurality of workpieces. A rigid retainer member is inserted into the slot to urge the resilient strip against the bore to increase the resistance force between bolt and bore against separation until such time as the retainer member is removed.In another application of the invention, a threaded fastener having a head and a shank is inserted into a through opening in workpieces until the end protrudes and is fastened with a nut. An axial slot in the threaded fastener is aligned with an axial channel of the nut. A strip, having a protruding lug near its distal end, is passed through the slot of the threaded fastener until the protruding lug enters the channel of the threaded nut. The portion of the strip extending beyond the head of the threaded fastener is bent into a groove in the surface of the head of the threaded fastener, preventing accidental disassembly of fastener and nut.

Abstract: A spindle nut and a locking device are disclosed for securing the nut on a spindle in a non-rotative position relative to the spindle. The assembly comprises the spindle nut, an antirotation spring and a spring backup plate mounted on the spindle. The antirotation spring and spring backup plate may be formed as a single unit.

Abstract: A spindle nut and a locking device for securing the nut in a rotative position on a spindle. An anti-rotation spring and a back up plate are mounted on the spindle in a non-rotative manner with the back up plate in abutment with the bearings that rotatively mount the hub to the spindle. The back up plate has multiple grooves aligned with and arranged to receive multiple resilient tabs on the periphery of the anti-rotation spring. The tabs of the anti-rotation spring are formed to project axially from the spring. A flange of the nut has multiple slots around its periphery that are sized to receive a tab of the anti-rotation spring. A tool having extending ears that fit in the slots of the nut is utilized to install the nut on the spindle. The extending ears prevent the tabs of the spring from entering a slot of the nut until the tool is removed. As the nut is rotated by the tool, the nut abuts the anti-rotation spring.

Abstract: A lock assembly for securing nuts to rotatably driven shafts in which a generally U-shaped locking spring is mounted with one leg thereof disposed along an opening in the rotatably drive shaft or a component keyed to the shaft and the other leg thereof disposed through and beyond a hole in the nut with a tab portion of such leg extending perpendicularly of the hole so that the tab will be urged outwardly of the hole by centrifugal force as the drive shaft is rotated to thereby create a more secure engagement of the locking spring with the nut.

Abstract: A pin lock for a turnbuckle of an ajdustable link on a three-point hitch. The pin locks the threads of the turnbuckle and is retained in the locking position by a retainer ring.
