Predetermined breaking body for shaft of machine, shaft having predetermined breaking body, and machine having shaft of this type

The invention relates to a predetermined breaking body (1), to a shaft (2) having a predetermined breaking body (1), and to a machine (3, 35, 36) having a shaft (2). The predetermined breaking body (1) has a first partial body (4), a second partial body (5) and a predetermined breaking element (6), by means of which the partial bodies (4, 5) are connected to one another in a rotationally fixed manner along a longitudinal center axis (7) of the predetermined breaking body (1). Here, the predetermined breaking element (6) is anisotropically designed such that, when a torque (M1, M2) is transmitted between the partial bodies (4, 5), the predetermined breaking element (6) yields in a first torsion direction (D1) at a predetermined first torsional breaking moment and yields in a second torsion direction (D2) opposite the first torsion direction (D1) at a predetermined second torsional breaking moment. The predetermined torsional fracture moments are different in magnitude. 本发明涉及一种预定断裂体(1)、一种具有预定断裂体(1)的轴(2)以及一种具有轴(
