    • The safety coupling (10) comprises: a first coupling part (12) and a second coupling part (14) which are arranged coaxially with each other so as to rotate about a same axis of rotation (x) and are provided with respective front teeth (20, 62); and torque- sensitive releasing means (44, 64, 70, 72) designed to uncouple the first coupling part and second coupling part, thus interrupting the transmission of the torque, when the torque transmitted between the two coupling parts exceeds a given maximum torque value. The torque-sensitive releasing means include: a plunger (44) which is permanently connected for rotation with the second coupling part and is slidable along the axis of rotation between a normal working position, in which it ensures that the two coupling parts are coupled for rotation with each other, and a safety position, in which it uncouples the two coupling parts; a pressure chamber (64) filled with incompressible fluid such as to apply on the plunger a force tending to keep the plunger in the normal working position; and valve means (70, 72) adapted to allow the fluid to be discharged from the pressure chamber, and hence the plunger to be moved from the normal working position to the safety position when the pressure of the fluid in the pressure chamber exceeds a given maximum pressure value, the maximum torque value being linked to the maximum pressure value. The front teeth are first front teeth (20) provided on the first coupling part and second front teeth (62) provided on the plunger, which teeth directly mesh with each other when the plunger (44) is in the normal working position.
    • 安全联轴器(10)包括:第一联接部件(12)和第二联接部件(14),它们彼此同轴设置,以绕相同的旋转轴线(x)旋转,并且设有相应的前齿 (20,62); 以及扭矩敏感释放装置(44,64,70,72),其被设计成当所述两个联接部件之间传递的扭矩超过给定的最大扭矩值时,使所述第一联接部件和所述第二联接部件脱开,从而中断所述扭矩的传递 。 转矩敏感的释放装置包括:柱塞(44),其永久地连接以与第二联接部件一起旋转,并且可以在正常工作位置之间沿着旋转轴线滑动,在该工作位置确保两个联接部件联接 彼此之间旋转,以及安全位置,其中它将两个联接部分分开; 填充有不可压缩流体的压力室(64),以在柱塞上施加趋于将柱塞保持在正常工作位置的力; 以及阀装置(70,72),其适于允许流体从压力室排出,并且因此当压力室中的流体的压力超过给定值时,柱塞将从正常工作位置移动到安全位置 最大压力值,最大扭矩值与最大压力值相关联。 前齿是设置在第一联接部上的第一前齿(20)和设置在柱塞上的第二前齿(62),当柱塞(44)处于正常工作位置时,该齿彼此直接啮合。
