摘要： A supporting device includes first and second supporting flanges coupled with first and second transmissions, respectively, and a support via which a supporting force is transmittable from the first supporting flange to the second supporting flange. The support includes a lever element which is coupled in an articulated manner with an attachment element on the first supporting flange and thus articulated with the first supporting flange, and a supporting element which is coupled in an articulated manner with the lever element and connected to the second supporting flange and which includes two spaced-apart supporting parts. The lever element is arranged partly between two spaced-apart attachment parts of the attachment element and partly between the supporting parts of the supporting element and is coupled in an articulated manner with the attachment element via the attachment parts and in an articulated manner with the supporting element via the supporting parts.

摘要： Embodiments relate to robotic arm assemblies. The robotic arm assembly includes an end-effector assembly. The end-effector assembly includes an instrument assembly. The instrument assembly includes an instrument and instrument driven portion. The elongated body includes an instrument central axis. The instrument driven portion includes a first central axis. The instrument driven portion is secured to a proximal end of the instrument in such a way that, when the instrument driven portion is driven to rotate, the instrument rotates relative to the first central axis. The end-effector assembly includes an instrument drive assembly. The instrument drive assembly includes an instrument drive portion. The instrument drive portion includes a second central axis. The instrument drive portion is configured to drive the instrument driven portion to rotate the distal end of the instrument relative to the first central axis. The second central axis intersects with and orthogonal to the first central axis.

摘要： A carrier assembly for a planetary gear assembly includes a planet frame defining a central aperture therethrough, the central aperture defining a rotation axis, the planet frame configured to rotatably support a plurality of planet gears, and a carrier connected to the planet frame via a stud. At least one of a portion of the carrier proximate the stud and a portion of the stud between the carrier and the planet frame has a dimension reduction, such as a thickness reduction, therein.

摘要： A gear transmission system embodying a unique twin pitch belt is provided. The twin pitch belt provides external first pitch gear teeth and a second pitch gear teeth synchronously engaging a fixed housing gear teeth and output gear teeth, respectively. The first and second pitch gear teeth may have the same gear pitch if different number of teeth though offset by a distance relative to each other. The first and second pitch gear teeth have less teeth than the housing and output gear teeth, in turn twice countering the rotation of an input shaft operatively associated with the twin pitch belt, resulting in the output gear teeth rotating in the same direction as the input shaft.

摘要： A first gear pair includes a first pinion on an input shaft and a first ring gear on an intermediate shaft. A second gear pair includes a second pinion on the intermediate shaft and a second ring gear on an output shaft. A first case that stores the first gear pair is coupled to a base member in a rotatable manner around an input shaft rotational axis. A second case is coupled to the first case in a rotatable manner around an intermediate shaft rotational axis.

摘要： A ring gear arrangement, including: a ring gear mount including: a ring gear having at least one internal gear for interaction with one or more gear wheels; a ring gear stator; and, a plurality of couplings which locate the ring gear within the gear stator, each coupling having a drive arm connected to the ring gear and a resiliently deformable connection, wherein the drive arm is movable between a first position in which the ring gear is in a rest position and a second position in which the ring gear has undergone some radial or rotational movement relative to the ring gear stator, wherein movement of the drive arm from a the first position to the second position loads the resiliently deformable connection against the ring gear, wherein the resiliently deformable connection biases the drive arm to return to the first position when in the second position.

摘要： A gearbox assembly for an electric power assisted steering apparatus comprises a gearbox housing which houses a worm shaft and a gear wheel, the worm shaft being supported relative to the housing by a main bearing at an end closest to the motor and by a tail bearing at an end furthest from the motor, and the gear wheel being supported by an output shaft having at least one end that provides a take-off from the gearbox assembly, in which the main bearing and tail bearing are free to move relative to the housing through a limited range of motion that enables the worm shaft to pivot away from the wheel gear facilitated by tilting of the main bearing about a pivot that is fixed relative to the housing, characterised in that the gearbox assembly is arranged such that the pivot reacts the axial component of the worm shaft tooth load that arises when a gearwheel torque is applied to the gearwheel in a first direction but not in a second, opposing, direction, and in that a tensioning device is provided that reacts the axial component of the worm shaft tooth load that arises when a gearwheel torque is applied to the gearwheel in the second direction but not in the first direction.
