  • Patent number: 8820183
    Abstract: A deceleration mechanism comprises a base, a transmission device rotatably connected to the base, and a driving device fixed to the base. The transmission device includes a driving assembly having a driving wheel and a driven assembly having a driven wheel. Diameter of the driven wheel is greater than that of the driving wheel.

  • Publication number: 20130090194
    Abstract: A reducing device having a cable or a belt and cable, providing a high reduction ratio, and including: two driving drums; two sheave wheels; at least one driving cable traveling from a first driving drum to one sheave wheel, from the one sheave wheel to the second driving drum, from the second driving drum to the other sheave wheel, and from the other sheave wheel to the first driving drum; a driven cable, including one strand which travels from a fork of the one sheave wheel to a driven wheel, and one strand which travels from the driven wheel to a fork of the other sheave wheel. The driving drums have different diameters and/or different rotation speeds so rotation thereof causes movement of the sheave wheels driving the driven cable, and rotation movement of the driven wheel. The reducing device is applicable, for example, to robots and haptic interfaces.

  • Patent number: 7654923
    Abstract: By providing a plurality of cylindrically shaped tube members nested together in coaxially aligned relationship, with each tube member being connected to a separate and independent control segment, with the control segments being constructed for raising and lowering the associated tube segment, an easily produced, reliable, dependable, and highly portable telescopically extendable and retractable multi-element system is realized. In the preferred embodiment, each control segment incorporates a separate endless loop drive belt which is cooperatively associated with a pair of pulleys mounted at opposed ends of the segment. Furthermore, each control segment is interconnected to the endless loop drive belt of an adjacent segment for causing all of the segments to move simultaneously in response to the initial movement of a first control segment.

  • Publication number: 20030176247
    Abstract: This invention replaces the crank-and-chain drive system of the conventional bicycle. A flexible drive line is pulled directly away from the hip by a stirrup located at the “ball” of the foot and drives the rear-wheel hub by means of a cone-shaped spool with a spiral groove. Routing pulleys mounted to a sliding shifter provide drive-ratio variability by adding line to or removing line from the spools, thus utilizing spool segments of varying diameter. A tensioned rewind system enables each spool, when driving the hub, to rewind the other. Benefits of this system as compared to prior art include: (1) the fact that the machine itself, as opposed to the operator's leg, changes the leg's naturally linear motion to rotary; and (2) a smoother, more efficient means of drive-ratio variation with the added advantage of infinite variability within limits.

  • Patent number: 6622072
    Abstract: To improve the maintainability of a vehicle by properly identifying a worn endless belt in a belt-type automatic transmission and informing a driver of the proper belt replacement interval. The belt replacement timing annunciator relies upon the radii of the endless belt wound around a drive pulley and around a driven pulley that vary to produce shifting change gear ratios. Various operating conditions and the actual change gear ratio for the specific operating condition are detected, and a comparison between a reference change gear ratio and the actual change gear ratio is made to determine if belt replacement is necessary. A timer device provides a predetermined observation interval for avoiding erroneous readings and a display is also provided for indicating the necessity of belt replacement.

  • Patent number: 5830093
    Abstract: A continuously variable transmission system for coupling between a rotating drive shaft and an output shaft employs a first drum rotated by the drive shaft and a second drum connected to the output shaft. At least one, and typically both, of the drums have a region of adjustable effective diameter. A closed cable encircling the first and the second drums is wrapped around each of the first and the second drums a plurality of times so as to provide effective tractional locking even at low clamping forces. In preferred embodiments, a mechanism is provided for preventing creep of the cable along the drum. The mechanism typically includes a number of elements each having a helical groove and deployed such that the cable engages a part of the groove, and a mechanism for rotating the elements so as to change the portion of the groove with which the cable engages.

  • Patent number: 5152575
    Abstract: A manual tarp enclosing system is disclosed for enclosing flat bed trailers which has an elongate track on each side and a plurality of U-shaped bows bridging the bed with one of the legs of the bow received in the track on each side of the bed for movement longitudinally in the track means. A cable positioning system for moving and positioning the bow is provided which comprises a closed loop of cable which extends along one side, across the width and down the other side of the bed as parallel double strands. A first bow is secured to one of the cable strands running parallel each of the tracks whereby on manually pulling on the loop of the cable, the first bow is moved towards the front or rear of the bed. A cover is secured to the first bow and at successive intervals to successive of the bows. On drawing the first bow, the cover extends or collapses in an accordion-like manner.

  • Patent number: 4351197
    Abstract: Precision positioning apparatus includes a rotatable driving element connected to a rotatable driven element having a diameter substantially greater than that of the driven element, and rotary movement of the driving element imparts rotary movement to the driven element. The diameters of the two elements are related so that a relatively large movement of the driving element results in a relatively small movement of the driven element, and vice versa.
