轴-齿轮-连接装置
摘要：
本发明涉及一种轴-齿轮-连接装置(1)，该轴-齿轮-连接装置具有轴(2)和热压套装的齿轮(4)。热压套装的齿轮具有借助第一热压配合部(8)固定在轴(2)上的第一轴向区段(5)和借助第二热压配合部(9)固定在轴(2)上的第二轴向区段(6)。通过第二热压配合部(9)能够将比通过第一热压配合部(8)更大的转矩从齿轮(4)传递到轴(2)上。根据本发明，在第一轴向区段(5)与第二轴向区段(6)之间设置有轴向中间区段(7)，该轴向中间区段借助第三热压配合部(10)固定在轴(2)上。通过第三热压配合部(10)能够将比通过第一热压配合部(8)更大的转矩和比通过第二热压配合部(9)更小的转矩从齿轮(4)传递到轴(2)上。根据本发明的轴-齿轮-连接装置(1)能够传递特别大的转矩，而在此不增加外齿部(11)的齿(12)上的损坏风险。此外，本发明涉及一种用于制造这种有利的轴-齿轮-连接装置(1)的方法。
摘要（英）：

The invention relates to a shaft-gear connection (1) comprising a shaft (2) and a shrunk-on gear (4). The shrunk-on gear has a first axial section (5) that is attached to the shaft (2) by means of a first shrink fit (8) and a second axial section (6) which is attached to the shaft (2) by means of a second shrink fit (9). The second shrink fit (9) allows greater torques to be transmitted from the gear (4) to the shaft (2) than the first shrink fit (8). According to the invention, an intermediate axial section (7) that is attached to the shaft (2) by means of a third shrink fit (10) is providedbetween the first axial section (5) and the second axial section (6). The third shrink fit (10) allows greater torques to be transmitted from the gear (4) to the shaft (2) than the first shrink fit (8) and smaller torques than the second shrink fit (9). The shaft-gear connection (1) according to the invention allows particularly great torques to be transmitted without increasing the risk of damaging the teeth (12) of the external gear (11). The invention further relates to a method for producing such an advantageous shaft-gear connection (1).
