STRUCTURAL ARRANGEMENT FOR OBSTRUCTIONLESS SUPPORTING IN BEARINGS THE FUNCTIONAL ROTARY UNITS HAVING HORIZONTAL AXIS OF AGRICULTURAL TILLING AND/OR HARVESTING ADAPTERS

摘要

The guide and penetration bearing structure comprises a cylindrical journal of the rotating active part, which journal is mounted so that it can rotate in a bearing casing fixed removably to the lateral wall or the chassis structure of the modifiable machine.
A shoulder part 7 of the bearing casing 4 and an edge sleeve 8 of the rotating active part 5 mutually overlap in the axial direction over a length which exceeds by several times the thickness of the air gap 10 left between them.
Application to agricultural machines in which the stalks and strands of plants (crops) to be harvested tend to wrap (wind) around the rotating parts of the bearings and penetrate into them.
