Transmission of power and data by means of an oil bushing ring
An arrangement includes a structure affixed to a housing, a planetary carrier mounted rotatably in the structure affixed to the housing, an oil bushing ring, and a first means and a second means for contactless power transmission. The oil bushing ring forms a lubricant-conducting joint between the structure affixed to the housing and the planetary carrier. The structure affixed to the housing has the first means and the oil bushing ring has the second means.
1. An arrangement, comprising:
a structure affixed to a housing,
a planetary carrier mounted rotatably in the structure affixed to the housing,
an oil bushing ring having a central axis, and
a first means and a second means for contactless power transmission,
wherein the oil bushing ring forms a lubricant-conducting joint between the structure affixed to the housing and the planetary carrier,
wherein the structure affixed to the housing has the first means and the oil bushing ring has the second means, and
wherein the first means is arranged radially further from the central axis of the oil bushing ring than the second means.
2. The arrangement according to claim 1 , wherein the oil bushing ring is made of plastic.
3. The arrangement according to claim 1 , wherein the first means is configured to be cast into the oil bushing ring.
4. The arrangement according to claim 1 , wherein the first means is a coil or a permanent magnet, and wherein the second means is a coil.
5. The arrangement according to claim 1 , wherein the planetary carrier has at least one sensor and at least one means for transmitting power from the at least second means to the at least one sensor.
6. The arrangement according to claim 5 , wherein the first means and the second means are configured to transmit data between one another.
7. The arrangement according to claim 1 , wherein the contactless power is transmitted in a radial direction relative to the central axis of the oil bushing ring.
8. The arrangement according to claim 1 , wherein the first means is configured to rotate about the central axis of the oil bushing ring and around a radial circumference delimited by the second means.
9. A planetary transmission, comprising:
a transmission structure affixed to a transmission housing;
a planetary carrier mounted rotatably in the transmission structure;
an oil bushing ring having a central axis, the oil bushing ring forming a lubricant-conducting joint between the transmission structure and the planetary carrier;
a transmitter arranged in the transmission structure; and
a receiver arranged in the oil bushing ring,
wherein the transmitter and the receiver are configured to contactlessly transmit electrical power between one another, and
wherein the transmitter is arranged radially further from the central axis of the oil bushing ring than the receiver.
