摘要：
The invention relates to a mechanism for securing a shaft-hub connection (16) of two shafts (12, 14), especially for securing a power take-off shaft extension to a power take-off shaft of a tractor. Said mechanism comprises a locking element (40) which prevents an established shaft-hub connection between the two shafts (12, 14) from detaching in an axial direction. One of the two shafts (12) is provided with a hub (15) encompassing means (38) for establishing a positive connection to the other shaft (14). The other shaft (14) is provided with means (22) for establishing a positive connection to the shaft (12) that is equipped with the hub (15). The locking element (40) is embodied in a substantially annular manner and is disposed on the first of the two shafts (12). In order to make it easier than in prior art to axially secure the shaft-hub connection (16), the locking element (40) is fitted with a gear (44) that is embodied essentially complementary to a gear (22) of the second of the two shafts (14). The locking element (40) is arranged so as to be twistable relative to the first shaft (12) from a locked position into an unlocked position. The gears (22, 44) overlap in the locked position while not overlapping in the unlocked position. The locking element (40) is placed such that an established shaft-hub connection (16) between the two shafts (12, 14) in the locked position of the locking element (40) is secured by the contact of the gear (44) of the locking element (40) with the gear (22) of the second shaft (14). The invention further relates to a shaft (12) comprising a securing mechanism.
摘要（中）：
本发明涉及一种装置，用于固定两个轴（12,14），特别是用于PTO轴固定到拖拉机的动力输出轴的轴毂连接（16）。 该装置包括一个锁定元件（40），利用该两个轴（12,14）之间产生的轴毂连接（16）的释放可在轴向方向上被阻止。 一项所述的两个轴（12）的具有用于向其他轴（14）刚性连接的轮毂（15）的装置（38）。 另一轴（14）具有装置（22）用于与所述轴（12）与所述轮毂（15）的正极连接。 所述锁定元件（40）是大致环形的并且布置在第一两个轴（12）的。 由此，轴毂连接（16）的轴向锁定比以前更容易使用，它建议，所述锁定元件（40）具有齿部（44），其是将两个中的第二个齿部（22）基本上互补 形成波（14）。 从锁定位置到解锁位置可相对于所述第一轴（12）的锁定元件（40）。 在锁定位置中，齿部（22，44）布置成彼此重叠。 在解锁位置，所述齿（22，44）不被设置成相互重叠。 所述锁定元件（40）被布置成使得在锁定元件（40）的锁定位置具有两个轴之间通过锁定元件的齿部（44）的抵接产生的轴毂连接（16）（12,14）（40 ）（在第二轴的齿22）（14）被固定。 此外，本发明涉及一种轴（12）与一固定装置。
