ROTARY SUPPORT DEVICE Russian patent published in 2019 - IPC B66C23/84 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building, in particular to the rotary support. Rotary support device contains the slewing ring consisting of movable upper and lower rings, stationary gear rim, adjusting flat gasket, bolt, fastening the movable rings upper and lower semi-cages, the turning part bolt, the ring fixed gear rim to the machine fixed part fastening bolt and the roller rolling bodies. Movable upper and lower rings and the adjusting flat gasket are made with tapered surfaces with possibility of displacement relative to each other elimination under horizontal and vertical loads. Movable upper and lower rings are made for the rings with tapered holes fastening, with the taper height of not less than equal to 0.4 mm maximum allowable gap, and the adjusting flat gaskets are made with conical ones, respectively, protruding to the height of not less than the maximum allowable clearance of 0.4 mm, profiles on the flat surface along the fastening diameter in the different directions at an angle of 180°, which tightly seat in the movable upper and lower rings conical openings, thereby not allowing the rings opportunity to move relative to each other.
