<p>The invention relates to a rotary transmission device for machine tools, comprising a stator part that is rigidly attached to the machine, a rotor part that is rigidly attached to the tool and can be rotated about a rotational axis, and stator-side and rotor-side transmitting and receiving elements for bidirectionally transferring data without contact. According to the invention, in order to guarantee trouble-free data transfer even for inductive energy transmission at high power, the transmitting and receiving elements are designed as optoelectronic components, which are combined on the stator part and the rotor part to form stator-side and rotor-side transmitter groups and receiver groups each having associated transmitting and receiving electronics. The transmitting and receiving elements of the rotor-side and stator-side transmitter and receiver groups associated with each other face each other in pairs by means of an axial light-guiding segment and are arranged relative to each other in such a way that the transmitter and receiver groups associated with each other communicate with each other by means of at least one of the transmitting and receiving elements thereof in each rotational position of the rotor part relative to the stator part.</p> |
