摘要： An aircraft wheel rotating device for effecting rotation of a wheel of an aircraft prior to landing includes a mounting plate in which a plurality of holes is positioned. Respective holes are alignable with bolts of a hub of a wheel that is rotationally attached to an axle of an aircraft. The mounting plate thus is mountable to the hub. A tubular housing is attached to and extends axially from the mounting plate. Each blade of a plurality of blades is rotationally attached to the tubular housing. The blades engage an airstream to rotate the wheel about the axle. A pitch adjustment module is operationally engaged to the plurality of blades and is positioned to selectively adjust a pitch of each blade to substantially match a tangential speed of the wheel to a speed of the aircraft relative to the ground at landing.

摘要： A bicycle hub with an axle, a shell, a rotor with a rotor body and a freewheel device with, a hub-side toothed disk device coupled to the hub shell, and a rotor-side toothed disk device interacting therewith and coupled to the rotor body, to drivingly couple the rotor to the hub shell in the driving direction and decouple from one another when freewheeling. The toothed disk devices include an end toothing and are biased to an engagement position. A sprocket accommodation is on the rotor body which includes on the hub-side end an inner radial wall to support a hub-side rotor bearing. On an end face at the hub-side end of the rotor, radially between the inner radial wall and an rotor outer wall, a circumferential accommodation accessible from the end face is configured, so the rotor-side toothed disk device is accommodated in a fixed driving manner and axially movable.

摘要： A bicycle rear sprocket assembly comprises a plurality of bicycle sprockets comprising a first sprocket and a second sprocket. The first sprocket includes a first opening having a first minimum diameter that is smaller than a minimum outer diameter of a sprocket support body of a bicycle rear hub assembly. The second sprocket includes a second opening and at least ten internal spline teeth. The second opening has a second minimum diameter that is equal to or larger than the minimum outer diameter. The at least ten internal spline teeth are configured to engage with the sprocket support body of the bicycle rear hub assembly. The at least ten internal spline teeth include a plurality of internal-spline driving surfaces each including a radial length. A total of the radial lengths of the plurality of internal-spline driving surfaces is equal to or larger than 7 mm.

摘要： A wheel hub driving system, including a housing, an electric motor, two planetary gear sets and a wheel hub bearing. The wheel hub bearing has a middle axle and an outer ring, the middle axle is fixed relative to the housing, and both a primary sun gear and a secondary sun gear are sleeved around the periphery of the wheel hub bearing. A stator of the electric motor, a primary geared ring and a secondary geared ring are all fixed to the housing. A rotor of the electric motor is anti-torsionally connected to the primary sun gear. A primary planet carrier is anti-torsionally connected to the secondary sun gear, a secondary planet carrier is anti-torsionally connected to the outer ring and the outer ring is configured to be anti-torsionally connected to a wheel rim so as to transmit power from the electric motor to the wheel rim.

摘要： A bicycle rear wheel adapter has an annular body that abuts a sprocket-carrying body that extends in an axially outer direction and receives sprockets in radially peripheral positions. A coupling element on the annular body couples with the sprocket-carrying body so the adapter rotates as a unit with the sprocket-carrying body, and a sprocket-receiving seat on the annular body couples with a sprocket so the adapter rotates as a unit with the sprocket. The adapter is suitable for cogsets with small sprockets grouped in a monolithic grouping.
