摘要： A linkage-based shifting assembly comprises first and second arms, having a first wheel rotatably coupled to a proximal end of the first arm and a second wheel rotatably coupled to a proximal end of the second arm. A shifting assembly is configured to couple to a chassis, wherein the shifting assembly is coupled to distal ends of the first and second arms and configured to cause a relative shifting motion between the chassis and the first and second wheels. The linkage-based shifting assembly can form part of a vehicle. The vehicle can be a two-wheeled vehicle. The vehicle can be a mobile carrier. The mobile carrier can be a two-wheeled vehicle.

摘要： A gear drive, such as for an actuator, is a right-angle drive where toothed outer ridge of a face gear is coupled to teeth of a motor output shaft, and a set of planetary gears are engaged with a central sun gear of the face gear. The sun gear and planetary gears are aligned with the motor output shaft. For instance the motor output shaft may be substantially in the same plane with the sun gear and the planetary gears. From another standpoint the axis of the motor output shaft may intersect the sun gear, as well as intersecting a volume that the planetary gears sweep through as the planetary gears engage the sun gear.

摘要： A roller shade assembly, installed in a window opening, having a frame with opposing first and second ends attached within the window opening. A roller is rotatably mounted to the frame with opposing ends, a rotational axis, and a first gear coaxially attached to one end of the roller. A drive assembly is attached to the frame between the first and second ends, having a second gear that is selectively rotatable and is operatively engaged with the first gear for imparting rotational motion from the drive assembly to the roller.

摘要： The present invention relates to a line gear mechanism with variable-angle transmission, which consists of a line gear pair having intersecting shafts which includes a driving line gear and a driven line gear. The driving line gear and the driven line gear are each composed of a wheel body and a line tooth. Contact curves of the driving line gear and the driven line gear mesh according to a pair of space conjugate curves. One or more line teeth are provided on the driving line gear. The line tooth on the driven line gear is a line tooth that has a property of variable-angle transmission. During transmission, the mechanism may adjust a transmission angle of the line gear pair having the intersecting shafts, thus causing meshing points to form on different contact curves while a transmission ratio remains unchanged and the transmission is stable.

摘要： A spatial crossed-axis transmission mechanism includes a rotatable driving member, an actuating member, and a support member for fixing the driving member and the actuating member. The driving member comprises a first end surface adjacent to the support member, and an Archimedes spiral groove is defined in the first end surface of the driving member. The actuating member includes an end surf adjacent to the support member and a sliding shaft on the end surface of the actuating member. The support member defines a straight groove passing therethrough, and the sliding shaft comprises an end that extends through the straight groove and fits into the Archimedes spiral groove.

摘要： A gear assembly is provided. The gear assembly includes a first gear that rotates about a first axis and includes a first gear face with a plurality of first gear teeth; a second gear that rotates about a second axis and includes a second gear face with a plurality of second gear teeth, where the first axis is not parallel with the second axis and the first and second teeth rotatably engage as the first gear rotates about the first axis and the second gear rotates about the second axis; a scraper that includes a distal interference surface in face-to-face proximity with at least one of the first plurality of teeth as the first gear rotates about the first axis, where the interference surface removes oil entrained adjacent to the plurality of first or second gear teeth as the first or second gears rotate.

摘要： A modular robot for use as an educational robot system having multiple degrees of freedom and mounting features that allow multiple modules to be assembled with accessories to form a multitude of configurations. Each module is independently mobile and useful when alone or assembled with other modules. An encoder gear and encoder gear track is used to sense multiple degrees of freedom with parallel and perpendicular axis of rotation using a single printed circuit board.

摘要： This mechanism for driving motions of a surface of spherical, ellipsoidal, plane, or other shape comprises a pair of drive wheels mounted on a freely pivoting frame, each wheel being driven by its own bidirectional motor. The motors and the active electronics of an angle encoder are mounted in an associated fixed frame, so no slip rings or other rotating connections are needed for motor power and control, or for determining the rotation angle of the pivoting frame. Control of the motors provides differential rotation of the two wheels to effect controlled rotation of the pivoting frame, and therefore of wheel direction. This avoids the use of a separate motor for changing the direction of motion of the surface. All parts of the mechanism driving wheel rotation are enclosed by the pivoting frame or the fixed frame.
