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.

Disclosed is a wheel assembly including a main rotation part that is to be rotated about a first rotation axis, a power transmitting part that receives power from the main rotation part, and a variable rotation part that receives a rotational force from the power transmitting part to be rotated about a second rotation axis when the main rotation part is rotated, and to be moved relative to the main rotation part such that the first rotation axis and the second rotation axis overlap each other or are spaced apart from each other.

Aspects of the present disclosure are directed to, for example, drive systems for transport devices. In one example embodiment, a drive system is disclosed including at least two drive wheels, at least one wheel bearing, at least one rim of the at least one of the drive wheels mounted by means of the at least one wheel bearing, at least one drive of the at least one of the drive wheels is arranged within the at least one wheel bearing, and at least one braking device coupled to at least one of the drive wheels. The at least two drive wheels are aligned on a common first axis, the drive wheel axis of rotation, which is angled relative to a second axis, the pendulum axis, and a third axis, a pivot axis, is likewise arranged at an angle relative to the first and second axes.

A wheel bearing arrangement for a motor vehicle with a wheel hub and a wheel bearing for the rotatable bearing of the wheel hub at a wheel mount. The wheel bearing has an outer ring and an inner ring, which is rotatable with respect to the outer ring around an axis of rotation and is connected to the wheel hub. A wheel flange extends from the wheel hub and, as viewed in the axial direction, has a brake disk mount, which is open in the direction facing away from the outer ring and which, as viewed in longitudinal section with respect to the axis of rotation, is formed by a recess of the wheel flange, and has a support surface for a brake disk.

A wheel mounting structure relates to a structure for fixing the wheel to the wheel hub which includes a substantially cylindrical spigot joint part protruding from the hub axle part toward the vehicle body outer side with respect to the flange part. In the spigot joint part, the first cylindrical outer peripheral surface and the groove are formed. The annular protruding part is provided so as to protrude toward the center of the wheel from the inner peripheral surface of the center hole. In a state where the wheel is fixed to the flange part using the fastening members, the fitting part and the annular protruding part fit with each other. In a state where the fastening members are removed, the annular cylindrical protruding part is engaged with the groove.

A bicycle component includes a hub shell for a wheel of an at least partially muscle-powered bicycle, wherein the hub shell is rotatably supported by at least one bearing device. An adapter unit is disposed on one end of the hub shell. The adapter unit includes an inner stopper having an inner stop face for transferring a clamping force to the bearing device and an outer stopper with an outer stop face transmitting at least part of the clamping force. The adapter unit includes a first and a second stopper component transmitting the clamping force.

An axle assembly having a planetary gear set and an internal brake assembly. The brake assembly may have a piston that may be disposed between a disc pack and the planetary gear set. Rotation of a sun gear of the planetary gear set may be inhibited when the piston urges the disc pack against a flange of an axle housing.

A driving device for a carriage includes a motor, a speed reducer, and a mecanum wheel. The speed reducer decelerates the power input from the motor and outputs a decelerated power. The mecanum wheel is rotated by the decelerated power output from the speed reducer. The speed reducer includes a speed reducing unit, a carrier, and a case. The speed reducing unit receives the power from the motor. The carrier supports the speed reducing unit. The case is rotatable relative to the carrier. The mecanum wheel is fixed on the case or the carrier.

A combination structure of a hub and spokes is provided, including: a hub shell, having separate small and large flanges, the small and large flanges having first and second assembling holes, respectively; a plurality of first spokes, assembled to one of the first assembling holes and a wheel rim; a plurality of second spokes, including cylindrical spokes and aero bladed spokes, the cylindrical spokes and aero bladed spokes being alternatively assembled to the second assembling holes and to the wheel rim; as viewed along an axial direction of the hub shell, every two of the second spokes which are neighboring to each other intersect with each other to define an intersecting area, each first spoke extends and passes through one of the intersecting areas.

Electric motors are disclosed. The motors are preferably for use in an automated vehicle, although any one or more of a variety of motor uses are suitable. The motors include lift, turntable, and locomotion motors.
