FIELD: machinery. ^ SUBSTANCE: this invention covers some alternatives of a bush joint. Alternative 1: the bush joint includes the body, first flange which radially protrudes the body and has a number of pits; herewith each row of pits has an arch notch. The second flange radially protrudes the body. There is a slot in the area limited by the body, the first and the second flanges. The bush is made so that it intrudes the pit, and its opening intrudes the shaft. Coupling torque between the bush and the shaft increases by max. 25% at increase of interference fit between the bush and the pit. Alternative 2: the bush joint includes the bush, first and second flange, row of pits with semicircular notches on perimeter of the first and the second flange, and spring element connected to the bush. The spring element is located around the body and adjoins at least one flange. The bush is made so that it intrudes the pit, and the shaft intrudes the bush opening. ^ EFFECT: decrease of friction and wear during mechanical parts interaction. ^ 15 cl, 11 dwg |
