FIELD: mechanical engineering.
SUBSTANCE: invention can be used in machines for cleaning grain. The prefabricated crank shaft for the grain separator comprises connecting rod and main journals with ball bearings installed on them, split connecting rod cheeks and main cheeks without cuts of the same width. At the same time, the connection of the connecting rod journals with the split cheek without gaps is ensured by compression of the cheek in the region of the slot by the force of the coupling bolt. A key is installed in the connection of the connecting rod journal with the split connecting rod cheek. The connecting rod journals between the split cheeks are connected by a butt shaft.
EFFECT: simplified design.
