GEAR TOUGH WHEEL Russian patent published in 2017 - IPC F16H55/14 

FIELD: machine engineering.

SUBSTANCE: gear tough wheel comprises a hub, a crown with a disk mounted rotatably relative to the hub, cylindrical elastic elements mounted without clearance in the socket, formed evenly around the wheel circumference. In the drive crown, the internal projections are made, which alternate with regulated gap with the outer ridges formed on the hub, socket made blind at the junction of mentioned projections of disk of a wreath and the hub on both ends of the wheel. One half of every slot is arranged on the internal ledge plate of disk of a wreath, the other one being made on the hub external ledge. Adjacent outer hub protrusions and the inner protrusions on the ring drive lugs conjugate on a plane perpendicular to the plane of rotation and passing through the axis of the sleeve, on which a pair of cylindrical elastic elements is coaxially placed. All external hub height projections are formed equidistant from its center, with spherical surfaces on the ends, in contact with the cavities between internal projections in the disk rim. The crown is formed of two halves releasably connected by bolts, each half of the teeth is made with the same oblique and opposite in direction to an inclination angle, and the crown surface depressions are spherical with a radius equal to the radius of the spherical surface of the hub projections.

EFFECT: increase in durability of the gear wheel.
