Definitions
- the invention relates to a device for transmitting electrical Current from a fixed connection to a rotatable one Ring, for example in electrical machines or cable drums.
- a device for transmitting electrical Current from a fixed connection to a rotatable one Ring for example in electrical machines or cable drums.
- electrical currents for example, on the Fixed shaft of the rotor of an electrical machine isolated Metal rings arranged on which brushes as a conductive connection Grind from the runner to the stand.
- a similar power transmission takes place on cable drums, where individual slip rings on the cable drum are attached and the transmission through to the Slip rings running brushes takes place.
- These attached carbon brushes made of copper or silver graphite or similar materials essential wear part, with great abrasion of the brushes Amounts of conductive material arise, which as coal dust in the Slip ring system falls and has an extremely disruptive effect.
- DE C-198 17 796 describes a device for the transmission of electrical current from a central rotating slideway one or more arranged around the central slideway Rolls known, in which an endless wire passed over the rollers Slideway touches tangentially and by the resulting frictional forces is moved. The speed of the wire can go through appropriate damping or additional friction in the rollers to be controlled.
- US 5977691 and US 421320 describe devices for transmission of electrical current from a fixed connection a rotating ring or drum, in which the electrical contact via one or more around the ring or the Tapes of electrically conductive material that are guided around the drum are formed which are the peripheral surface of the ring or drum to contact.
- the invention is based on the object of such a system propose where the emergence of large amounts of conductive Material is avoided by abrasion.
- An advantageous embodiment provides that on the insulating tube several sockets, separated by insulating washers, are arranged.
- impellers be made of sintered Material, the alloy brass rings and the tension spring high-alloy material.
- the main advantage of the invention is that the Brush and thus the abrasion. Another advantage results from the fact that the individual poles in a narrow design can be manufactured so that control poles in a confined space can be accommodated. Due to the tension spring used the advantage that greater tolerances on the tension Center distance can be taken over by the tension spring and for example another tension wheel or the like can be omitted.
- the device has a socket 3 with a diameter enlarged part 13 and a reduced diameter part 14, an impeller 1 being mounted on part 14.
- the impeller 1 supports on the shoulder between the parts 13, 14 of the socket 3.
- the Socket 3 is on an insulating tube 4, which is above a stud 5 is arranged, attached.
- a fixed electrical connection 6 is provided, which has a Cable line 15 with cable lug connected to a cable terminal block 7 is.
- a metallic ring 2 which is held on studs 9 with insulating tubes 10, several such rings 2 are provided by interposed insulating washers are.
- the wheel 1 and the standing ring 2 are each with Provided grooves 17 and 16 and by means of a tension spring 12 as Drive element connected.
- the rings 2 can be made very narrow, so that it A number of impellers makes sense when connecting several circuits 1 with the bushings 3 distributed around the circumference of these rings 2.
- a number of impellers makes sense when connecting several circuits 1 with the bushings 3 distributed around the circumference of these rings 2.
- In the drawing is an opposite arrangement of a dashed line such impeller 1 shown to connect to a to produce middle ring 2.
- the next ring 2 can again by a roller 1 on the opposite side be connected.
- A is advantageously used for the corresponding electrical transmission high alloy tension spring used while the running wheel 1 off sintered material, expediently with gold, silver or Rhodium is staggered.
- the socket 3 is also corresponding built from highly conductive material.
- the rings 2 can be normal conductive material, such as brass, possibly alloyed with corresponding materials, such as gold, silver or rhodium.
