Definitions
- the invention relates to a slip ring transmitter according to the features in the preamble of claim 1.
- Slip ring assemblies are electromechanical components that are used to transfer energy, data and/or control signals from a rotating to a stationary component or vice versa. They are used in applications that, due to their rotary motion, do not allow energy and data to be supplied via a permanently installed cable.
- a slip ring transmitter of the usual design has a slip ring carrier and at least one slip ring arranged on the slip ring carrier and a contact module with contact elements, in particular contact springs.
- a contact module is also referred to as a brush block in technical terms.
- the slip rings and contact elements are an essential part of the construction.
- the contact elements make contact with a sliding track of the slip ring and together with this form a sliding contact. Due to the relative movement between the components, there is a continuous slight abrasion during operation. In order to keep abrasion as low as possible, the running partners are wetted with oil. Despite this lubrication, abrasion cannot be avoided. The abrasion combines with the oil and adheres to the components, especially the slideway. This Pollution is not only detrimental to the transmission of energy and data, but can also lead to a disruption in the insulation, resulting in operational interruptions.
- the DE 298 07 515 U1 a rotating cleaning device for the continuous cleaning or keeping clean of contact-tapping grinding devices.
- the device has a cleaning roller formed from cleaning rings, which is pressed against the sliding track.

- a cleaning module with a movable cleaning brush is arranged on the stator of the electric motor, which is pressed onto the collector by means of a spring and retracted by means of an electromagnet when an electrical voltage is applied to the electric motor.
- the invention is based on the object of creating a slip ring transmitter with a functionally and operationally improved cleaning device.
- a slip ring transmitter has a slip ring carrier and at least one slip ring arranged on the slip ring carrier and a contact module with contact elements.
- the contact elements are in particular contact springs. However, other contact elements, for example carbon brushes, can also be used as contact elements.
- the contact elements make contact with a sliding track of the slip ring.
- a cleaning device for cleaning the sliding track.
- the cleaning device has a cleaning brush with a brush lining that makes contact with the sliding track.
- the cleaning brush absorbs the abrasion and ensures a thin, even film of oil on the grinding track. As a result, impairments caused by abrasion or dirt can be avoided. In particular, very good energy and/or data transmission between the slip ring or slip track and the contact elements is ensured.
- the cleaning brush has a base body which has a back web and a brush holder.
- the cleaning brush is fixed to a carrier plate of the contact module over the back web and connecting elements.

Description
Die Erfindung betrifft einen Schleifringübertrager gemäß den Merkmalen im Oberbegriff von Anspruch 1.The invention relates to a slip ring transmitter according to the features in the preamble of
Schleifringübertrager sind elektromechanische Bauteile mit deren Hilfe Energie, Daten und/oder Steuersignale von einem rotierenden auf ein feststehendes Bauteil oder umgekehrt übertragen werden. Sie werden bei Anwendungen eingesetzt, die aufgrund ihrer Drehbewegung keine Energie- und Datenversorgung über eine ortsfest verlegte Leitung zulassen.Slip ring assemblies are electromechanical components that are used to transfer energy, data and/or control signals from a rotating to a stationary component or vice versa. They are used in applications that, due to their rotary motion, do not allow energy and data to be supplied via a permanently installed cable.
Ein Schleifringübertrager der üblichen Bauart weist einen Schleifringträger und zumindest einen auf dem Schleifringträger angeordneten Schleifring sowie ein Kontaktmodul mit Kontaktelementen, insbesondere Kontaktfedern auf. Ein Kontaktmodul wird fachterminologisch auch als Bürstenblock bezeichnet. Die Schleifringe und Kontaktelemente sind wesentlicher Bestandteil der Konstruktionen.A slip ring transmitter of the usual design has a slip ring carrier and at least one slip ring arranged on the slip ring carrier and a contact module with contact elements, in particular contact springs. A contact module is also referred to as a brush block in technical terms. The slip rings and contact elements are an essential part of the construction.
Die Kontaktelemente kontaktieren eine Schleifbahn des Schleifrings und bilden zusammen mit dieser einen Schleifkontakt. Aufgrund der Relativbewegung zwischen den Bauteilen kommt es im Betrieb kontinuierlich zu einem geringfügigen Abrieb. Um den Abrieb so gering wie möglich zu behalten, werden die Laufpartner mit Öl benetzt. Trotz dieser Schmierung lässt sich der Abrieb nicht vermeiden. Der Abrieb verbindet sich mit dem Öl und haftet auf den Bauteilen, insbesondere der Schleifbahn. Diese Verschmutzung ist nicht nur nachteilig für die Energie- und Datenübertragung, sondern kann auch zu einer Störung der Isolation führen, mit der Folge von Betriebsunterbrechungen.The contact elements make contact with a sliding track of the slip ring and together with this form a sliding contact. Due to the relative movement between the components, there is a continuous slight abrasion during operation. In order to keep abrasion as low as possible, the running partners are wetted with oil. Despite this lubrication, abrasion cannot be avoided. The abrasion combines with the oil and adheres to the components, especially the slideway. This Pollution is not only detrimental to the transmission of energy and data, but can also lead to a disruption in the insulation, resulting in operational interruptions.
