An assembly is disclosed including a first component, a second component, and a spacer component. The first component has a first interface surface. The second component has a second interface surface with a curvature different to the curvature of the first interface surface. The second component is connected to the first component such that the second interface surfaces faces the first interface surface. The spacer component is disposed between the first interface surface and the second interface surface and is configured to be pivotable relative to the first interface surface.

A system, including a pin having a first cylindrical portion defining a first central axis and a second cylindrical portion defining a second central axis that is parallel to and offset from the first central axis, a first plate with a first aperture matching with the cross section of the first cylindrical portion; a second plate with a second aperture matching with the cross section of the second cylindrical portion, the second plate lying against the first plate where the first cylindrical portion of the pin is inserted in the first aperture and includes a first surface that axially abuts against the second plate and wherein the second cylindrical portion of the pin is inserted in the second aperture and includes a second surface that axially abuts against the first plate.

A connection assembly between two structures, the assembly including an assembly of two eccentric rings, one of which, the external ring, is fitted on the other, being formed as an insert, a bore of the internal ring being configured to fix to one of the structures using a fixing element, and the external ring being accommodated and retained in a through-opening of the other structure, at least one of the eccentric rings being made from a deformable material in order to at least compensate for a play when it is compressed by two retention and compression elements during assembly. Advantageously, it is thus possible to benefit from a mechanical play which facilitates the assembly and to eliminate this play during a tightening operation of the fixing element in order to improve a transfer of loads between the two structures.

A tolerance compensation arrangement for fastening first and second components with automatic or self-acting compensation of tolerances in the spacing between the components. The arrangement includes a base element having first and second metal elements with inner threads. An adjustment unit includes a threaded sleeve with an outer thread and a dragging unit at least partially arranged in the threaded sleeve. The outer thread forms a first thread pairing of a first thread direction with the inner thread of the first metal element. A fastening screw can be screwed into the inner thread of the second metal element via a second thread pairing of a second thread direction opposite to the first thread direction. The fastening screw can be connected to the adjustment unit via the dragging unit so that, during the rotation of the fastening screw, the adjustment unit co-rotates and is moved into abutment with the first component.

A fitted bolt connection is provided for connecting at least two components to holes to be matched comprises a fitted bolt having a conical surface for arrangement in a hole in the first component, three or more separate cone segments each for arrangement between the conical surface of the fitted bolt and an inner peripheral wall of the hole in the first component, and clamping bolts each associated with the cone segments, by means of which the cone segments, independently of one another, can each be individually clamped between the conical surface of the fitted bolt and the inner peripheral wall of the hole.

A fastening system has two fastening elements for mounting a bracket of a rail system of an elevator installation. The fastening elements each have a clamping plate having a through-hole and a receiving sleeve receiving an anchor bolt. The receiving sleeves each have a through-opening for the anchor bolt and an angularly movable ball joint is formed between the clamping plate and the receiving sleeve.

A liquid shim includes a bag (24) defining a closed inner volume and having sealed openings spaced inwardly from a periphery of the bag. The sealed openings are sealed from the closed inner volume and delimit holes extending through the bag. A liquid shim material (22) is flowable through the closed inner volume around the sealed openings and is curable to form a solid. The liquid shim material has a liquid shim material volume being less than the closed inner volume of the bag. A method of creating a liquid shim, and a method of shimming a gap between components, is also disclosed.

An adjustable fixed structure attachment system 200 for an aircraft wing, the attachment system 200 including a bracket 210 having: a wall 212 for connection to a wing box, a protrusion 214 protruding from the wall 212, and a slot 216 extending through the protrusion 214, wherein the slot 216 has a height and a width, and a bush 220 having a bore 222 extending therethrough for receipt of a pin, wherein the bush 222 is insertable into the slot 216 and dimensioned relative to the slot 216 so that the bush 220 is substantially immovable in a width-wise direction of the slot 216, and is moveable in a height-wise direction of the slot 216 to thereby vary a position of the bush 220 within the slot 216.

A component which is configured to be joined to a further component in a preselected relative orientation is disclosed. The further component has an interface surface and the component is configured to contact the interface surface when joined to the further component. The component includes a surface disposed on a side of the component intended to face the interface surface when the components are joined, a plurality of recesses formed in the surface, and a plurality of spacer elements. Each recess has a preselected orientation relative to the component, the preselected orientation being selected in dependence on the preselected relative orientation. Each spacer element comprises a contact surface configured to contact the interface surface when the components are joined. Each spacer element is disposed in one of the recesses such that the orientation of a given contact surface is defined by the orientation of the corresponding recess.

An eccentric bushing assembly comprises an outer eccentric bushing configured to be disposed in an opening of a panel comprising a central axis. The outer eccentric bushing is operable to float axially, rotate circumferentially, and to move radially with respect to the central axis. The eccentric bushing assembly further comprises an inner eccentric bushing disposed radially inward from the outer eccentric bushing and interfacing with the outer eccentric bushing, the inner eccentric bushing is operable to rotate relative to the outer eccentric bushing. The eccentric bushing assembly further comprises a spherical bushing comprising a through hole operable to receive a connecting pin therein and to rotate in at least one degree of freedom. The rotation of the spherical bushing can facilitate alignment of an axis of the pin with the through hole.
