FIELD: machine building.SUBSTANCE: invention relates to 2K-H gearboxes with two internal engagements for the torque transfer and transformation. The gearbox contains a cylindrical casing, rear cover, face cover with fixed central internal gearwheel, output shaft with movable central internal gearwheel, double external gearwheel with hole. The cylindrical U-shape insert with two open cylindrical holes is installed in hole of the double gearwheel, in one of them (central) the geared shaft is installed, and in the another one - satellite gearwheel. Teeth of the geared shaft are in engagement with teeth of the satellite gearwheel, and satellite gearwheel teeth are engagement with teeth of the internal engagement of the double tooth-wheel. Teeth of the internal engagement of the double tooth-wheel, teeth of the geared shaft and satellite gearwheel additionally using the cylindrical tips of the tooth heads execute function of the journal bearing cage. The wave profile of teeth provides the tooth-wheel rotation during work around the own axis and axis of the central tooth-wheels with set permanent eccentricity. At that teeth are in engagement with each other during the gearbox operation.EFFECT: improved operating characteristics of the gearbox.3 cl, 5 dwg |
