Abstract

The present invention relates to a lubricant guide ring for guiding a lubricant in a liquid state and a supply system. The lubricant guide ring includes a body having an annular shape, the body defining a channel. The channels (18) extend radially and are used for guiding the lubricant radially inwards from the radially outer part. The channel (18) is formed by a slot (15), with which the body (14) is interrupted in the circumferential direction to form free ends (16, 17), wherein the body (14) is designed to be resilient at least in sections and can be radially elastically varied by a relative movement of its free ends (16, 17) oriented in the circumferential direction. Furthermore, the body (14) is provided radially outwardly at its free ends (16, 17) with respective lubricant guide surfaces (22, 23) which extend obliquely radially inwardly relative to the outer circumferential side (28) of the body (14) toward the channel (18) and are each provided for guiding lubricant to the channel (18).

Description

Lubricant guiding ring for guiding lubricant in liquid state and supply system Technical Field The invention relates to a lubricant guiding ring for guiding a liquid lubricant, comprising a body in the shape of a ring, which defines a channel, wherein the channel extends radially and is used for guiding the lubricant radially inwards from the radially outer part. The invention also relates to a supply system with the lubricant guide ring. Background In technical terms, it is common in many fields to supply lubricant to the areas and components to be lubricated and/or cooled, for which purpose the respective areas and components are mostly connected to an associated supply system via which the lubricant is specifically supplied. In mechanical systems, therefore, for example, bearing positions, tooth meshing portions, etc. are supplied in a targeted manner. Within the respective supply system, the lubricant is here mostly removed from the lubricant reservoir via a delivery pump and delivered to the respective region or the respective component. In part, guide elements are provided in the supply system, via which guide elements a targeted guidance of the lubricant is respectively achieved in the region of the components to be supplied. A feed system is known from CN 209587U, in which a tooth engagement between the drive teeth can be supplied with lubricant, wherein a rotationally fixed connection between the two shafts is achieved via the tooth engagement. The lubricant is guided here via a lubricant guide ring, which guides the lubricant from the radially outer side. The lubricant guiding ring has an annular body, which has in particular radially extending channels, via which the lubricant is guided radially inwards from the radially outer part, respectively, and can then be guided to the tooth engagement. Disclosure of Invention Starting from the prior art described above, it is now the object of the present invention to provide a lubricant guide ring with which a suitable radial flow guiding of lubricant can be achieved, which, however, can also be fastened in a reliable manner as self-retaining as possible in the corresponding region of the supply system. This object is achieved starting from the preamble of claim 1 in combination with the distinguishing features thereof. The following dependent claims reflect advantageous refinements of the invention, respectively. Furthermore, the subject matter of claims 11 to 15 is a feed system in which a lubricant guide ring according to the invention is arranged. According to the invention, the lubricant guiding ring comprises a body in the shape of an annular, which body defines a channel, wherein the channel extends radially and is used for guiding the lubricant radially inwards from the radially outer part. The lubricant guide ring according to the invention is thus provided for guiding a liquid lubricant, in particular oil. This guiding of the lubricant takes place in the lubricant guiding ring according to the invention from the radially outer part radially inwards via a channel formed by the body of the lubricant guiding ring. The body of the lubricant guide ring is designed annular, which in the sense of the present invention is to be understood as meaning that the body of the lubricant guide ring is designed annular at least to a large extent in its cross section. Preferably, the body of the lubricant guide ring has, in addition to its annular shape, an extension in the axial direction, which, together with its annular cross section, gives the body a hollow-cylinder-like or tube-like shape. The invention now includes the technical teaching that the channel is formed by a slit with which the body is interrupted in the circumferential direction to form a free end. The body is designed to be resilient at least in sections and can be radially elastically varied by a relative movement of its free end oriented in the circumferential direction. Furthermore, the body is provided at its free end radially outwardly with a respective lubricant guiding surface which extends obliquely radially inwardly towards the channel with respect to the outer circumferential side of the body and is provided for guiding the lubricant towards the channel. In other words, the annular body is thus formed as a slit, wherein the slit extending through the body defines a radially extending channel. In addition to the radial channels, the free ends of the body are also formed in the circumferential direction via slits, wherein the body of the lubricant guide ring according to the invention is embodied to be resilient at least one partial section, so that the body can be radially elastically varied by a relative movement of the free ends of the body in the circumferential direction with respect to one another. Furthermore, the body is provided at its free end with a lubricant guiding surface, which is here arranged radially outside the body at the respective end. The respective lubricant gui
