    • 专利摘要:
    A push element for a transmission belt comprising an endless carrier packed with a plurality of such elements to run on Vee-pulleys with variably spaced side plates. The surface of the element which comes into contact with the inside surface of the carrier is of convex shape to minimize wear resulting from improper alignment of the elements in use.

    (54) BELT TRANSMITTER
    one
    The invention relates to flexible couplings and can be used in belt drives for transmitting significant torques between two V-shaped pulleys, the distance between the side disks of which can be varied in order to change the gear ratio.
    A belt drive pusher, mounted on an endless carrier, is known, which is a single metal tape or a bag of such tapes. The smoothness of the pusher in contact with the inner surface of the supporting element is made flat in the transverse direction 1.
    However, during the operation of the pusher, intense transfer wear occurs at the points of contact between the lateral sides of the belt pack and the pushers.
    The purpose of the gear is to reduce gear wear.
    This is achieved by the fact that the surface of the pusher, which connects with the inner surface of the bearing element, is made in the transverse direction rounded and convex. In addition, the radius of curvature is convex
    surface ranges from 150 to 2000 mm.
    FIG. Figure 1 shows a pusher belt transmission; in fig. 2 5 pusher for ribbon package; in fig. 3 - pusher for two ribbon bags.
    The belt drive contains two V-shaped pulleys 1 and 2 and a belt 3, O consisting of a row of pushers 4, mounted on an endless support element.
    5, made in the form of a package of endless ribbons. Surface pusher
    6, which is in contact with the inner surface of the supporting element, is made in the transverse direction rounded AND convex, the radius of curvature of which lies in the range from 150 to 2000 mm. Pushers can
    20 be performed both for one ribbon package (see Fig. 2) and for two (see Fig. 3).
    Transmission works as follows.
    The torque between the two V-shaped pulleys 1 and 2 is transmitted by the pushing force through a series of individual pushers 4, tightly worn on the bearing to look for element 5. At the same time,
    That the tension in the bearing element was always greater than the pushing force transmitted by the thrusters mounted on the bearing element.
    Bearing element 5 tends to be disposed at a higher point on the surface of the pushers, thereby eliminating the lateral contact of bearing element 5 with pushers 4, as a result of which gear wear is reduced,

    Claims (2)
    [1]
    1. A pusher for a belt drive consisting of a row of pushers attached to a carrier.
    made in the form of a single metal tape or package, so that I, with the aim of reducing transmission wear, the surface of the pusher in contact with the inner surface of the supporting element is made in the transverse direction rounded and convex.
    [2]
    2. The pusher according to claim 1, is also distinguished by the fact that the radius of curvature of the convex surface lies in the range from 150 to 2000 mm.
