An adaptor is used to couple a prime mover to an actuator. The adaptor includes a first portion that attaches to the prime mover and a second portion that attaches to the actuator. The outer surface of the first portion is defined by at least one flat portion connected by at least one arcuate portion. The second portion has a bore configured to accept the first portion, with an inner surface shaped to complement the outer surface of the first portion. A bore through the first portion accepts a drive shaft of the prime mover therethrough where the drive shaft is configured to engage the actuator.

A locking bracket and methods of using the same are disclosed. The locking bracket includes a rigid body and a locking pin slidably and rotatably coupled to the rigid body and movable between an unlocked position and a locked position. An engagement member can enter and exit the rigid body when the locking pin is in the unlocked position but is locked to the rigid body when the locking pin is in the locked position. Optionally, the rigid body may include a guide portion that guides the engagement member to a mounting position within the rigid body. The methods include swinging an attachment component towards a main body until the engagement member engages the locking bracket coupled to the main body, removing the locking pin from the unlocked position, and locking the attachment component to the bracket by placing the locking pin in the locked position.

A connection arrangement (4, 4′) of two components (1, 2) according to the invention has a curved surface portion having a contact point on at least one of these components. The curved surface portion can extend over the entire surface of a groove, for example. The other component has a taper. When assembling the two components before a force is applied, a line connection is created from the 2-contact point connection and when force is applied, the line connection changes through plastic deformation into a strip connection, on the basis of which the two components (1, 2) hold together.

A rivet structure includes a female rivet plate and a male rivet plate. The female rivet plate defines an elongated countersunk hole. A size of the countersunk hole increases from a first side of the female rivet plate to a second side of the female rivet plate. The male rivet plate includes a rivet including a shaft portion and two head portions. The shaft portion extends from the male rivet plate. The two head portions are respectively arranged on opposite sides of the shaft portion on a side of the shaft portion facing away from the male rivet plate. The two head portions extend through the countersunk hole from the first side of the female rivet plate to the second side of the female rivet plate. The two head portions are configured to be stamped by a stamping member to fill in the countersunk hole.

A nozzle device according to some embodiments includes an annular nozzle plate, an annular nozzle mount defining a nozzle flow passage between the nozzle mount and one surface of the nozzle plate, at least one nozzle support coupling the nozzle plate and the nozzle mount, and fixed to at least the nozzle plate by caulking, and at least one nozzle vane supported between the nozzle plate and the nozzle mount. The nozzle plate has a through hole into which an end portion of the at least one nozzle support is inserted. The through hole includes a straight portion extending from the one surface toward another surface of the nozzle plate, an enlarged diameter portion formed on a side of the another surface of the nozzle plate and having a larger diameter than the straight portion, and a relief processing portion which is formed in a part of the straight portion continuing into the enlarged diameter portion and has a larger diameter than another part of the straight portion where the relief processing portion is not formed.

A profile assembly having a first profile and having a second profile connected on its long side to the first profile, which two profiles each have a hook strip integrally formed on the long side, wherein the hook projection of the hook strip of the first profile points in the one direction, and the hook projection of the hook strip of the second profile points in the opposite direction, the hook strips brought into engagement with one another in a claw-like manner. The first profile has an anchoring channel following its longitudinal extent, and the hook strip of the second profile has a clamping strip which is integrally formed thereon, which hook strip is secured by its hook projection and its clamping strip in the anchoring channel of the other profile by a cold joining connection. In order to produce the cold joining connection, one of the two hook strips comprises an adjusting strip which is formed by the cold joining process and which is supported in the produced profile assembly by its free end face while being under prestress. The hook strip secured in the anchoring channel is placed under prestress within the anchoring channel, at two points situated opposite one another in the direction of the height of the profile assembly, with respect to the adjoining portions of the first profile as a result of the cold joining connection.

A method of assembly includes forming a first member to include a plurality of elastically deformable locating protrusions extending outward from an exterior surface of the first member. A locating protrusion is an elongate member having an arcuate portion, a first linear leg portion extending from a first arc end, and a second leg portion extending from a second arc end. The method additionally includes forming a second member to include a plurality of elastically deformable compression features. The locating protrusions are inserted in press fit engagement with the plurality of compression features such that the first member and the second member are secured relative to each other and the average of the elastic deformation between all of the plurality of locating protrusions and all of the plurality of compression features precisely aligns the first member relative to the second member.

A connecting sleeve suitable for the production of a push-pull link bar includes a main body, a coupling section which is formed or arranged on the outer circumferential side on the main body, and a through bore, characterized in that the connecting sleeve has a first seal which is arranged at least partially on the outer circumferential side and a second seal which closes at least the through bore.
