Abstract (en)

Assembly of an engine-driven shaft (1) and a boss (5) connectable with it, of a part (4), in which, for establishing said connection, said shaft (1) and said boss (5) are provided with mutually adapted screw threads arranged on an outer and inner conical part, respectively, said screw thread having a trapezoidal cross-section. For connecting a cutter shaft (1) and the boss (5) of a cutter (4), the screw threads (2, 7) of both parts and the parts themselves are designed such, that screwing said parts together can take place until one flank (9) and top (13) of one screw thread (2) tightly abut a flank (12) and a valley (14) of the screw thread (7) of said other part (4), while both trapezoidal screw threads (2, 7) have been designed such, that there is tolerance between the other flanks (10, 11). <IMAGE>
