A rolling element is between the cam unit and the first crown gear, and the cam unit includes a first member that couples to the input or output shaft and a second member made of steel and including a rolling element rolling portion where the rolling element rolls, the second member configured to be incapable of rotating relatively to the first member, and at least part of the first member having a lower specific gravity than the second member.

The present disclosure proposes a motive power transmission apparatus (10), comprising: a first shaft (100), extending along a central axis and comprising a hollow cavity (130), with a first spline part (110) provided on an inner peripheral wall of the hollow cavity; a second shaft (200), extending along the central axis and comprising a second spline part (210) provided on an outer peripheral wall of the second shaft, the second spline part being engaged with the first spline part to enable the second shaft to rotate together with the first shaft; wherein the motive power transmission apparatus (10) further comprises a sealing cap (300), the sealing cap comprising a base part (310) and a circumferential part (320) extending around the base part, and the sealing cap is configured to be elastically deformable.

A driver for coupling a driving device and a driven device includes a core defining a plurality of corner chamfers and a casing formed on and encasing the core. The casing has a contoured perimeter surface and a variable casing thickness, and is compressible during an interference fit installation to a coupling socket to provide a non-lubricated coupling which has zero backlash and substantially no running noise. The core is made of a metal-based material and includes a shaft bore for receiving an input shaft. In an illustrative example, the driver core is made of a stainless steel core and the casing is made of a high wear thermoset urethane material. The metal core can be recycled from the coated driver by removal of the polymeric casing, then recoated with a new casing to form a new coated driver including the recycled metal core.

A system configured to couple an implement to a work vehicle includes a first lock assembly coupled to an arm of the work vehicle, and the first lock assembly includes a first lock, a second lock, and a first actuator configured to drive the first lock and the second lock laterally outwardly to engage respective first openings formed in the implement. The system also includes a second lock assembly coupled to a frame of the work vehicle, and the second lock assembly includes a third lock, a fourth lock, and a second actuator configured to drive the third lock and the fourth lock laterally outwardly to engage respective second openings formed in the implement.

A flexible coupling assembly for a power transmission system includes a first circular disk defining a u-shaped radial cross-section including a first leg and a second leg connected at an inner diameter thereof circumscribing an axial bore of the flexible coupling and disconnected at an outer diameter of the first circular disk configured to connect to a first rotating member interface and a second circular disk defining a u-shaped radial cross-section including a first leg and a second leg connected at an inner diameter thereof circumscribing the axial bore of the flexible coupling and disconnected at an outer diameter of the first circular disk configured to connect to a first rotating member interface.

Provided are a joint component formed with fine recessed portions so that degradation of the flatness of a metal base body, such as a core, to which a joint object such as a friction member is joined can be reduced, a multiplate clutch device including the joint component, and a joint component manufacturing method. At a friction plate (200) as the joint component, many fine recessed portions (204) are formed at a joint surface (203) as a portion of a core (201) joined to friction members (207). The joint surface (203) is formed in a circular ring shape along a peripheral direction of the core (201), and is formed with a flatness of equal to or less than 0.15 mm. The fine recessed portions (204) are formed at the joint surface (203) such that adjacent ones of the fine recessed portions (204) do not overlap with each other and a formation density per unit area (Ua) at the joint surface (203) is uniform. The fine recessed portions (204) are formed as laser processing marks formed at the core (201) by irradiation with laser light L.

A joining tool (10) is provided for pressing a disk (12) to a shaft (14) that has opposite first and second ends. The first end (18) of the shaft (14) is received in a press table (22) and the second end (24) of the shaft (14) is received in a centering receptacle (26). A press plate (34) axially presses the disk (12) onto the shaft (14). A resilient ram (40) is provided on a side of the press plate (34) that faces toward the disk (12) and compensates for an axial run-out of the disk (12) relative to the press plate (34). The resilient ram (40) of the joining tool (10) enables the disk (12) that has an axial run-out to be pressed onto the shaft (14) in a correspondingly sloped manner, with the result that a rotor shaft (16) with a satisfactory bond is made possible.

A hybrid module includes a first, motor-side pre-assembly group and a second, transmission-side pre-assembly group. A separating clutch is arranged between the motor-side pre-assembly group and the transmission-side pre-assembly group, via which the pre-assembly groups can be connected in a torque-transmitting manner.

A steering shaft for a motor vehicle may have an inner shaft, an outer shaft, and a profiled sleeve that is fixed on the inner shaft such that the inner shaft is movable together with the profiled sleeve in an axial direction relative to the outer shaft. The inner shaft and the outer shaft may be coupled in a torque-transmitting manner with the profiled sleeve connected therebetween. The profiled sleeve may comprise an aperture into which a projection on an outer face of the inner shaft engages in a manner that secures the profiled sleeve in position on the inner shaft at least in the axial direction.
