FIELD: machine building. ^ SUBSTANCE: chain transmission includes sprockets (1, 2) and rope (3) with balls (4) fixed on it. Rope is entered to longitudinal slots or holes of balls, and plugs (10) serving for rope tension are entered to threaded or clearance holes perpendicular to them. In the second version of chain transmission the rope has bushes fixed on it. For compensation of pitch increase during the rope drawing at the bushes there made are longitudinal threaded holes into which threaded plugs or screws are introduced. In the third version of chain transmission the flexible transmitting element is represented with two and more ropes which are entered to transverse grooves or holes of bushes and fixed in them. In the fourth version of chain transmission, in order to obtain closed rope loop, its ends are entered on both sides to transverse holes of closing ball or bush, which are assembled of two halves. In the fifth version of chain transmission the sprockets are provided with elastic teeth the sides of tops of which and on the side of cavities throughout the length of teeth, or on the side of their end surfaces, or in staggered order, or in various combinations there made are slots in radial direction. ^ EFFECT: invention allows increasing the service life of chains and sprockets, increasing heat resistance, reducing friction, compensating the chain pitch increase during the rope drawing, improving stability of transmission ratio and reducing the sensitivity of chains to misalignment of axes. ^ 17 cl, 15 dwg |
