A system includes a first vehicle component and a second vehicle component. The first vehicle component includes a first panel, a T-shaped projection protruding from a mating surface of the first panel, and a locking projection protruding from the mating surface of the first panel. The second vehicle component includes a second panel and a pair of ramped ribs projecting from a non-mating surface of the second panel. The second panel defines a slot that extends through the non-mating surface thereof. The slot includes a first portion having a first width and a second portion having a second width that is less than the first width. The ramped ribs are disposed on opposite sides of the second portion of the slot. The first vehicle component is configured to be fastened to the second vehicle component and located relative to the second vehicle component.

A connection system includes a shaft, a hollow shaft, a press ring, a first ring fitted onto the hollow shaft, a second ring, a bearing, and a housing part. The hollow shaft is rotatably mounted via the bearing received in the housing part and has an inner conical region. The first ring has a first outer conical region and a second outer conical region. The first outer conical region is positioned against the inner conical region of the hollow shaft and/or at least a partial region of the first outer conical region is arranged radially between the shaft and the hollow shaft. The second ring encloses and/or surrounds the first ring. The press ring touches both a partial region of the radially outer surface of the hollow shaft and at least one partial region of the radially outer surface of the second ring and/or is mounted onto these partial regions.

A support structure including: a body (12) having a press-fitting hole (36); and a collar (34) that is press-fit into the press-fitting hole. The support structure is characterized in that: the collar includes a press-fitting part (34a) at an area that is press-fit into the press-fitting hole, a flange part (34c) provided to one end side of the press-fitting part, and a distally-tapered tapered part (34b) provided to the other end side of the press-fitting part. The press-fitting hole includes a press-fitted hole at an area into which the press-fitting part is press-fit, an intrusion hole at an area into which the tapered part intrudes, and a circumferential groove part provided between the press-fitted hole and the intrusion hole. When the axial-direction length of the press-fitting part is a, the axial-direction length of the press-fitted hole is b, and the axial-direction length of the circumferential groove part is c, b<a<b+c.

A rotary assembly for an aircraft engine is disclosed. A shaft is mounted for rotation about a central axis and a rotary part is mounted on the shaft for common rotation therewith. The rotary part has an axial end portion extending away from a center of mass of the rotary part, the axial end portion having a radial thickness smaller than that of the rotary part at an axial location aligned with the center of mass. The shaft and the rotary part have an interface defining an interference fit between the shaft and the axial end portion of the rotary part. The interface is located at a distance along the central axis from the center of mass. An undercut is defined in the rotary part. The undercut extends axially from adjacent the interface towards the center of mass.

A support structure including a cylindrical insertion hole. Collars each having a flange formed at one end are press-fitted from both ends of the insertion hole, and fixing means are inserted into the collars. One end of the insertion hole is formed as a small diameter portion, and another end thereof is formed as a large diameter portion. The collars include a small diameter collar of which a press-fit portion has an outer diameter which is press-fitted into an inner diameter of the small diameter portion, and a large diameter collar of which a press-fit portion has an outer diameter which is press-fitted into an inner diameter of the large diameter portion.

The present disclosure relates to a method for use in installation of a mill liner, the method including (a) retaining a mounting bolt at least partially within a liner opening extending through the mill liner, (b) positioning the mill liner against a mill shell so that the retained mounting bolt is aligned with a mill shell opening extending through the mill shell, (c) selectively coupling an extraction tool to the mounting bolt, the coupling performed by an operator outside of the mill shell, (d) detaching the mounting bolt from the liner using the extraction tool; (e) pulling the mounting bolt through the mill shell opening so that at least a portion of the mounting bolt protrudes outside of the mill shell, and, (e) securing a fastener onto the mounting bolt to thereby attach the mill liner to the mill.

A precision threaded locator fastener bushing includes a driver portion, an exterior precision locating surface, an interior precision locating surface, and an exterior threaded portion. The precision threaded locator fastener bushing allows various fastening and precision locating devices to be precisely located relative to a fixture plate. The driver portion includes a ten-point driver configuration.

A fastener and a method of mounting the same in place includes a fitting portion, an engaging portion and a filler portion. The fastener passes through a sliding hole of an object, and then the fitting portion presses against the object, allowing a material of the object to enter or flow into the filler portion, so as to fit the fastener and the object firmly together. The engaging portion is engaged with or removed from another object. Therefore, the fastener and the method can couple together and separate at least two objects repeatedly and rapidly.

A profile system includes a series of elongate profiles (1) and one or more intermediate and/or end elements (8; 28). A series of connecting pins (14) each are a separate part having two end portions (15, 16) and being designed to releasably connect a profile (1) on the face side with an intermediate and/or with an end element (8; 28). The profile cross sections form on their face side receiving openings (5) for receiving the first end portion (15) of a connecting pin (14). The intermediate and/or end elements (8; 28) comprise receiving holes (13) for receiving the second end portion (16) of a connecting pin (14). The receiving openings (13) of the intermediate and/or end elements (8; 28) each extend through a wall into a cavity of the intermediate and/or end element (8; 28).

The present disclosure provides a washable straw including a plurality of connectable portions that me connected by at least one clasp. The connectable portions allow the straw to be opened or separated to allow for thorough cleaning and avoid the buildup or bacteria, mold, or other contaminants that cannot be removed in conventional straw designs.
