A bus bar assembly includes a bus bar formed of a first electrically conductive material having a planar contact portion. The bus bar defines a first bore extending through the contact portion. The bus bar assembly further includes a contact insert formed of a second electrically conductive material that has a greater hardness than the first electrically conductive material. The contact insert defines a first surface that is mechanically and electrically connected to the contact portion of the bus bar. The contact insert defines a second surface this is plated with a third electrically conductive material which is different than the second electrically conductive material. The contact insert defines a smooth second bore coaxial with the first bore and extending from the first surface to the second surface.

The present invention relates to an assembly of a first component (1) and a second component (2) of a wind turbine, the assembly comprises, a paired eccentric cam adjuster (10) adapted for a connection of the first component and the second component of a wind turbine, said components (1,2) each having at least one hole (3,4), the adjuster comprising, a first and second eccentric cam adjuster (7,8), both comprising, a tube (101) with an outer surface and an inner bore (103), with a first central longitudinal axis (321) of the outer surface having an offset (320) from a second central longitudinal axis (322) of the inner bore and a flange (102) arranged at one end of the tube, said cam adjusters (7,8) arranged to be inserted into said holes, and a bolt (5) and a nut (6) arranged to be inserted in the inner bores.

A buoyant fastener structure includes a body portion and a fastening element. The body portion has a rotation-preventing portion and a position-limiting portion. The fastening element has a position-corresponding rotation-preventing portion, a position-corresponding position-limiting portion and a fastening portion. The rotation-preventing portion and the position-corresponding rotation-preventing portion prevent each other from rotating. A rotation-preventing buoyancy level exists between the rotation-preventing portion and the position-corresponding rotation-preventing portion. The position-limiting portion corresponds in position to and limits the position of the position-corresponding position-limiting portion. Therefore, the body portion is coupled to a first object, whereas the fastening portion is coupled to or removed from a second object, so as for the first and second objects to be coupled together and separated, repeatedly and quickly. Furthermore, the second object coupled to the first object is movable on the fastening element to adjust the position of the second object.

A spacer element serving to obtain a spacer washer positioned between first and second parts of an assembly. The spacer element includes a body having the same geometry as the spacer washer that is to be obtained and a circular score line whose diameter is equal to the internal diameter of the spacer washer that is to be obtained, this score line being configured to break upon insertion of a shank of a connection element, and a centering pad configured to center the score line with respect to the through-orifices of the first and second parts that are configured to accommodate the shank of a connection element when the centering pad is inserted into one of the through-orifices.

A mating assembly is provided and includes a first mating component, a second mating component, a bolt to bolt first and second mating components together and an alignment pin. The alignment pin aligns the first and second mating components so that the first and second mating components can be bolted together. The alignment pin is configured to yield upon an application of a specified load thereto. A magnitude of the specified load is less than magnitudes of loads expected to be transferred between the first and second mating components through the bolt once bolting is complete.

The present invention relates to a vehicle body assembly structure allowing a distance between a vehicle body and a part to be adjusted in any of left-right, front-rear, and up-down directions with a simple structure such as a screw.

A dual-sleeve, locking adjustment arrangement includes a position-sensitive component comprising an aperture, an outer eccentric sleeve disposed in the aperture, and an inner eccentric sleeve disposed in the outer sleeve. Rotation of the outer sleeve with respect to the position-sensitive component and the inner sleeve drives rotation of the position-sensitive component to adjust an angular position of the component.

A bolt connection is provided for connecting two flanges. The bolt connection includes a threaded bar extending through a hole of a first flange and a hole of a second flange, the first flange abutting the second flange; an anti-fatigue sleeve; and a nut. The anti-fatigue sleeve is disposed on the threaded bar on the side of the first flange between the nut and the first flange, the nut is configured to be screwed onto the threaded bar and is configured to press the anti-fatigue sleeve against the first flange to fasten the first flange and the second flange together.

Methods and apparatus for retaining a fastener receiver are disclosed. An example apparatus includes a retainer to retain a nut assembly adjacent an object. The retainer includes a first plate defining a first opening. The first plate is to couple to the object. The first opening is to receive a portion of the nut assembly when the retainer is coupled to the object. The retainer includes a second plate defining a second opening and including a first deflectable tab adjacent the second opening. The second plate is to couple to the first plate opposite the object. The deflectable tab of the second plate is to cover a portion of the first opening of the first plate. The first deflectable tab is to deflect to receive and retain the portion of the nut assembly in the first opening when the retainer is coupled to the object.

A bolt for joining a first component and a second component, the bolt being capable of correcting a position of the second component with respect to the first component is provided. A bolt is fitted in a first hole of a first component and in a second hole of a second component in order to join the first component and the second component. The bolt includes a flange part, a threaded part, a head part, and a centering part. The centering part has a centering part body, and a plurality of blades. Each blade has an external-diameter increase portion in which a distance from the axis to an outer edge gradually increases toward a direction opposite to a tightening rotation direction of the bolt, and a distance from the axis to the outer edge gradually increases along an axial direction toward the flange part.
