A mechanical part (2, 3) including a functional surface intended to come into frictional contact with another functional surface, wherein the functional surface of the mechanical part (2, 3) is made of polyethylene furanoate.

A variety of transmission mechanisms are provided that include split pulleys nested within each other in order to reduce the size of the transmissions, to provide infinitely variable transmission ratios that include forward and reverse ratios, or to provide some other benefits. These transmissions include W-shaped belts, having both contact surfaces that are directed outward from the belt and inward, toward a center-line of the belt, to contact the pulleys with respective different inward- and outward-directed contact surfaces. Accordingly, the surfaces at which the belt contacts the different pulleys may be substantially the same with respect to a hinge or other structure of the belt. This improvement may permit higher levels of power transmission, increased efficiency, and increased transmission lifetime. Additionally, variable-eccentricity variable transmissions are provided wherein the eccentricity of rotation of an inner, nested pulley varies with changes in the transmission ratio of the transmission.

A method for designing a spline surface contour of a roller-type wave-motion includes of the steps of slicing radial movement track of a roller between a cam and a spline aperture and circumference rotation track at equal proportion at equal time intervals to sequentially obtain circle centers and points of tangency of the track circles during movement of the roller; connecting the points of tangency to form a unit cam circumference segment of a cam periphery in order to draw and form a single-sided tooth flank contour; and forming a correspondent side tooth flank contour by mirroring and projecting the single-sided tooth flank contour. A method of forming a spline wheel contour and a method of forming a cam periphery are obtained.

A sliding bearing 1 which is interposed between a tube 4 and a rack shaft 7 includes a bearing body 11 and two elastic rings 13 and 14 fitted on an outer surface 12 of the bearing body 11, and the bearing body 11 has slits 26 extending from an end face 22 to this side of an end face 24, slits 27 extending from the end face 24 to this side of the end face 22, an inner surface 33 having a sliding surface 28, and an outer surface 12 on which are formed grooves 34 respectively receiving the elastic rings 13 and 14 and projections 35 and 36 respectively provided on axial end portions 23 and 25 with the grooves 34 disposed therebetween.

A cladding structure and method for cladding machine components to inhibit crack propagation includes at least one set of primary bands, with each primary band being deposited adjacent to and abutting at least one other primary band, forming at least one inter-pass clad boundary, and at least one set of secondary bands deposited in a spaced configuration and oriented so as to intersect at least one inter-pass clad boundary.

A drive transmission mechanism includes a drive transmission gear, an output-side coupling, and a first drive transmission member. The drive transmission gear includes a cylindrical boss formed at the rotation center, a circular rim concentric with the boss, and a web coupling the boss with the rim. The output-side coupling outputs a driving force of the drive transmission gear to a driven member. The first drive transmission member has higher rigidity than the drive transmission gear, and transmits the driving force of the drive transmission gear to the output-side coupling by rotating together with the drive transmission gear. The output-side coupling incline in an arbitrary direction relative to the rotation axis of the first drive transmission member, and the driving force from the drive transmission gear is transmitted to the outer circumferential rim of the first drive transmission member.

A tendon actuator unit comprises a housing; a pulley disposed within the housing, the pulley comprising a screw-like groove about a predetermined portion of an outer surface of the pulley configured to accept a predetermined length of a cable; a motor disposed in or proximate to the housing and operatively in communication with the pulley; one or more online cable sensors; one or more sensor rollers; and one or more conduit force sensors.

An interlocking drive plate for an anilox roll which incorporates a dowel pin with a bushing that is able to move slightly and rotate. The interlocking drive disc is similar in structure to the current structure of a drive disc for the Mark Andy P-Series printing presses. However, the stationary dowel pin has been replaced with a modified dowel pin which includes a bushing providing slight movement and rotation. The modified dowel pin, with slight movement and rotation, reduces the shear forces on the pin which in turn reduces the wear on the pin when rotated by a servomotor. This reduction in wear will cause the interlocking drive disc to last longer than traditional drive discs without the need for repair or replacement.
