A gimbal joint may employ a plurality of wear sleeves, each disposed between a pin or pin receptive bore of a first structure and a corresponding bore or pin of a second structure and between another pin or bore of the second structure and a corresponding bore or pin of a third structure. Each of these structures may be adapted to rotate in a single plane, with one structure adapted to also tilt about a first axis, and one other structure adapted to tilt about a second axis. Each integral flanged wear sleeve may comprise a right circular hollow cylindrical body portion, which may be interiorly sized to be retained on one of the pins and externally sized to be retained in one of the pin receptive bores, and a flange portion may radiate from one end of the cylindrical body portion.

A pin assembly for a component, such as a trunnion bracket, includes a pin received in pin hole of the component, and a retainer received in a retainer opening of the component to releasably secure the pin in the pin hole. The retainer can be secured to the pin, such that the pin and lock assembly rotate as a single component.

A pin assembly is provided with an axial centerline. This pin assembly includes an outer pin, an inner pin, a first collar and a second collar. The outer pin extends axially along the axial centerline between an outer pin first end and an outer pin second end. The inner pin extends axially along the axial centerline within a bore of the outer pin. The first collar circumscribes the outer pin. The first collar is connected to the outer pin and the inner pin at the outer pin first end. The second collar circumscribes the outer pin. The second collar is connected to the outer pin and the inner pin at the outer pin second end.

A concentric bushing assembly is provided. The assembly includes a bushing having a bushing cylindrical body extending to a first outer diameter and a bushing flanged end extending to a second outer diameter that is larger than the first outer diameter. The assembly also includes an insert having an insert cylindrical body extending to a third outer diameter and an insert flanged end extending to a fourth outer diameter that is larger than the third outer diameter, the cylindrical body disposed within the bushing cylindrical body.

A heat treatment method is provided in which a first steel component (11) formed with a coating (111) thereon is fitted in first holes (123, 124) of a second steel component (12) subjected to a quenching treatment. The heat treatment method includes a heating step of heating the second steel component to a first temperature (T.sub.1) equal to or higher than a tempering temperature (T.sub.0) of the second steel component and higher than a temperature of the first steel component by a temperature difference (ΔT) for achieving shrink fitting and a shrink-fitting step of shrink-fitting the first steel component in the first holes of the second steel component in a state of maintaining the temperature difference for achieving shrink fitting between the first steel component and the second steel component.

The invention relates to a hinge comprising a first part (11) that can be pivoted relative to a second part (12) about a pivot axis (a), wherein the first part (11) comprises at least one bore (13) and the second part (12) at least one recess (15a, 15b), wherein, in a final assembly position, at least pin one (17a, 17b) that is coaxial to the pivot axis (a), has a first longitudinal portion in the bore (13) and with a second longitudinal portion in the recess (15a, 15b), and the pin (17a, 17b) can be moved between a pre-assembly position, in which the pin (17a, 17b) is in the bore (13) or in the recess (15a, 15b) with a larger overlap with respect to the final assembly position, and the final assembly position. The special feature is that at least one holding element (18) can extend through a passage (31) in a seat (28) in such a way that the pin (17a, 17b) can be moved by the holding element (18) from the pre-assembly position into the final assembly position and that, in the final assembly position, the holding element (18) is positioned in such a way that it prevents a return movement of the pin (17a, 17b) from the final assembly position into the pre-assembly position.
