A coupler is provided for a power-take-out axle of a gearbox. The coupler includes a coupling flange, a pinion, and a threaded bolt. The coupling flange includes a screw hole and the first curvic coupling member that are arranged in a concentric manner. The pinion is connected to a front end of the coupling flange, and includes a countersink hole, teeth and a second curvic coupling member arranged in concentric manner. The threaded bolt is inserted in the screw hole from the front end of the pinion through the countersink hole. Hence, the pinion and the coupling flange are bonded.

A method of loading a rotating assembly of a turbocharger can include positioning a swage collar on an end portion of a turbocharger shaft that extends through a through bore of a compressor wheel; applying a pulling force to the end portion of the turbocharger shaft to achieve a desired amount of loading; deforming the swage collar to form a swaged collar fixed to the end portion of the turbocharger shaft; and releasing the pulling force wherein the swaged collar maintains the desired amount of loading.

A compressor wheel assembly of a turbocharger can include a compressor wheel that includes a through bore that extends from a base portion to a nose portion of the compressor wheel; a turbocharger shaft disposed in the through bore of the compressor wheel where the turbocharger shaft includes an end portion that extends axially away from the nose portion of the compressor wheel; and a swaged collar fixed to the end portion of the turbocharger shaft.

A coupling assembly having a first member drivingly connected to a second member via one or more third members. A first shaft is drivingly connected to the first member and a second shaft is drivingly connected to the second member. The second member includes a flange portion having one or more seating portions on a first end portion of the flange. Additionally, the flange has one or more flange portion attachment apertures extending from the seating portions to a second end portion of the flange. An increased diameter portion of the second shaft has one or more increased diameter portion apertures extending from a first end portion to a second end portion. The flange portion apertures and the increased diameter portion apertures have a center-line with an angle from an axial center-line of the assembly. Additionally, the seating portions have an angle relative to a radial center-line of the assembly.
