Device for transmitting an electric current to a rotatably mounted rotating body

Abstract

A device for transmitting an electric current to a rotatably mounted rotary body (10) comprising at least two slip rings (11), comprising: a contact piece carrier (1) and at least two contact pieces (2), wherein the contact piece carrier (1) is mechanically connected to the respective contact piece (2), wherein the respective contact piece (2) can be arranged such that, when installed in an electrical machine with the rotatably mounted rotary body (14), the respective contact piece (2) is in contact with the respective slip ring (11), wherein an electrically insulating layer (3) is arranged between the contact piece carrier (1) and the respective contact piece (2), characterized in that the device has at least one guide element (5), wherein the respective guide element (5) can be arranged such thatthat when installed in an electrical machine with the rotatably mounted rotary body (10), the respective guide element (5) is in contact with at least one surface (12) of the rotatably mounted rotary body (10), wherein two guide elements (5) can be arranged in such a way that when installed in an electrical machine with the rotatably mounted rotary body (10), the respective surface (12) is arranged between the two guide elements (5), wherein the contact piece carrier (1) is coupled to the respective contact piece (2) by means of a respective elastic element (4), wherein the device has a holding element (6) and a further elastic element (7), wherein the holding element (6) is mechanically coupled to the contact piece carrier (1) via the further elastic element (7).

Claims

[1] Device for transmitting an electric current to a rotatably mounted rotary body (10) which comprises at least two slip rings (11), with - a contact piece carrier (1) and - at least two contact pieces (2), wherein the contact piece carrier (1) is mechanically connected to the respective contact piece (2), wherein the respective contact piece (2) can be arranged in such a way that when installed in an electrical machine with the rotatably mounted rotary body (14), the respective contact piece (2) is in contact with the respective slip ring (11), wherein an electrically insulating layer (3) is arranged between the contact piece carrier (1) and the respective contact piece (2), characterized by , that the device has at least one guide element (5), wherein the respective guide element (5) can be arranged such that when installed in an electrical machine with the rotatably mounted rotary body (10), the respective guide element (5) is in contact with at least one surface (12) of the rotatably mounted rotary body (10), wherein two guide elements (5) can be arranged in such a way, that when installed in an electrical machine with the rotatably mounted rotary body (10), the respective surface (12) is arranged between the two guide elements (5), wherein the contact piece carrier (1) is coupled to the respective contact piece (2) by means of a respective elastic element (4), wherein the device comprises a holding element (6) and a further elastic element (7), wherein the holding element (6) is mechanically coupled to the contact piece carrier (1) via the further elastic element (7). [2] Device according to claim 1, wherein at least one of the contact pieces (2) can be arranged offset in the radial direction to the respective slip ring (11).
