MECHANISM FOR FASTENING THE BEARING SUPPORTS OF THE CONVEYING SCREW DEVICE OF THE COMBINE HARVESTER Russian patent published in 2022 - IPC A01D41/12 A01B71/04 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. The mechanism for fastening the bearing supports of the conveying screw device of the combine harvester contains a housing, bushings, a bearing assembly mounted on the end surface of the bushings, and elements of fixing the bearing assembly on the housing. Flanges and a cover plate between two flanges are installed on the inner and outer sides of the housing. The inner diameter of the lining is combined with the inner diameter of the flange hole, and the inner diameter of the lining is smaller than the inner diameter of the flange hole, but no less than the diameter of the shaft passing through the lining. The size of the radial gap between the shaft and the inner diameter of the lining does not exceed the minimum grain size. The bushings are located between the outer flange and the bearing assembly. The flanges, bushings and bearing assembly are fixed to the housing by means of a bolted connection.

EFFECT: productivity of the combine harvester is increased, grain losses are reduced, the design is simplified and the service life of the bearing supports is increased.
