COMPENSATOR OF MIXING DRUM SKEWING Russian patent published in 2010 - IPC F16F1/44 B28C5/42 

FIELD: machine building.

SUBSTANCE: invention refers to compensator of skewing and to drive of mixing drum. The compensator consists of first element (5) and second element (12), one of which is made connectable or as a solid with a support pole. Flexible element (11, 15) compensating skewing and transferring weight of the mixing drum to the support pole is installed between the elements. First element (5) has pin (6) with external surface (7); radially projecting surface (13) adjoins each end of external surface (7) and forms a cavity between all these surfaces. Second element (12) has hollow component (8) with internal surface (10) enveloping pin (6) and with external surface (9). Radially directed surfaces (14), limiting or forming a bridge between them, are adjacent to external surface (9). The bridge is located between surfaces of the first element and divides the cavity limited with the said surfaces. Flexible elements (15) preliminary compressed with surfaces (13, 14) are arranged between surfaces (13) of the first element (5) and surfaces (14) of the second element (12). The drive of the mixing drum with the compensator includes first element (5) made integral with the case of the drive. In the case there are installed a planetary gear, crown gear of which corresponds to a driven link and a rolling bearing to transfer forces from the mixing drum to the case.

EFFECT: design of compensator receiving weight of drum and load from torque developed with drive.
