The invention relates to a planetary transmission (1) comprising a housing (2) and at least one planetary stage (3) that comprises at least one sun gear (5) which is provided on a sun gear shaft (6) rotatably mounted on the housing (2); at least one planet gear carrier (7) which is rotatably mounted on the housing (2), at least two planet gear pins (8) which are secured to the planet gear carrier (7) and on each of which a planet gear (9) is rotatably held; and at least one ring gear (11) which is secured within the housing (2) in a rotationally fixed manner, which comprises an inner toothing, and with which the planet gears (9) are in engagement. The invention is characterized in that an FOFW system is provided that has a request unit (23), at least one stationary antenna (24; 30) which is a electrically connected to the request unit (23) and is arranged within the housing (2); at least two FOFW sensors (25) which are secured to the planet gear pins (8); and at least a number of antennas (26) which are secured to the planet gear carrier (7) and rotate together with the planet gear carrier, said number corresponding to the number of planet gear pins (8). Each of the antennas is electrically connected to at least one of the FOFW sensors (25) and is arranged and designed to transmit measurement data detected by the FOFW sensors (25) to the at least one stationary antenna (24; 30). |
