Description

Field of the invention

[0001] The invention relates to a rolling bearing arrangement which is formed from at least a first and a second machine element, a cylindrical roller set, two bearing rings and a bypass device. Background of the invention

[0002] Rotor shafts in electrical machines are usually supported by rolling bearings. Unwanted voltage potentials often arise between the rotor shafts and housings of electric motors and generators. If countermeasures are not taken, these voltage potentials discharge through the rolling bearings. The current flowing through the affected rolling bearing can generate sparks in the rolling contact between the rolling elements and the raceways. The rolling raceways are damaged by melt pits or erosion pits.

[0003] Measures are already known to prevent the buildup or reduction of voltage potentials across the rolling bearings. For example, bypass devices are used, with which discharges are guided "around" the rolling bearings of the electric motor via so-called shaft grounding rings. DE 10 2016 010 926 A1 discloses such a bypass device consisting of a shaft grounding ring. This shaft grounding ring has a disk-shaped, electrically conductive bypass conductor, which is clamped towards the housing between two conductive angle plates and which rests against a shaft with elastic prestress on the inside. The angle plates forming the holder for the bypass conductor are inserted into a housing at any suitable location. The bypass conductor is made of a conductive material that has a lower resistance to flowing currents than, for example, steel.The advantage of such a bypass device is that the shaft grounding ring is simple and inexpensive to manufacture.

[0004] In the automotive sector, bypass conductors are also often integrated into sealing devices. An example of an upstream seal designed as a bypass conductor is disclosed in DE 10 2014 010 269 B4. The upstream seal is connected in series upstream of a main seal and, as a bypass conductor, simultaneously establishes an electrically conductive connection between two machine elements. The disc-shaped bypass conductor also protects the sealing lip of the main seal against environmental contaminants and is attached to the main seal. The main seal is mounted in the housing with a holder formed from an angled sheet.

[0005] Due to their primary application in electric motors and the resulting requirement for high relative speeds, the aforementioned bypass devices proposed in the prior art are generally used with ball bearings. The bypass devices are either provided within the bearing or are located at any point on the shaft. Cylindrical roller bearings, due to their design characteristics, are more suitable for higher loads and lower speeds and are increasingly used in industrial applications. Since the currents are greater in these applications, bypass devices for industrial applications can be arranged anywhere in the system, contacting the shaft. Description of the invention

[0006] The object of the invention is to provide an improved rolling bearing arrangement with bypass for higher-speed cylindrical roller bearings.

[0007] The object is achieved according to the subject matter of claim 1. The rolling bearing assembly has at least a first machine element and a second machine element, a cylindrical roller set, a static inner and a rotating outer bearing ring, and a bypass device. The cylindrical roller set comprises a plurality of cylindrical rollers. The cylindrical rollers of the cylindrical roller set are arranged radially between the inner and outer bearing rings and are directed radially transversely to the axis of rotation; the bearing ring is arranged concentrically on an axially aligned axis of rotation of the rolling bearing assembly. At least one electrical connection is formed between the first machine element and the second machine element via the bypass device. The bypass device has a holder and at least one electrically conductive bypass conductor, which are conductively connected to one another.The holder is secured by means of a positive fit between the inner bearing ring and a shoulder in the first machine element and holds the bypass conductor. A contact area is formed on the end face of the outer bearing ring, where the electrical contact between the bypass conductor and the outer bearing ring is established, with the bypass conductor making axial contact with the contact area.

[0008] Bypass devices are usually mounted on the outer bearing ring of a rolling bearing and rest more or less overlapping on the inner bearing ring or a shaft to ensure permanent mechanical and electrical contact. If the outer bearing ring or second machine element rotates, the bypass conductor can experience a reduction in contact force due to the rotation, even to the point of being lifted off by centrifugal force. If, however, the bypass device is instead located on the inner bearing ring, a reduction in contact force due to centrifugal force can be deliberately avoided in order to ensure reliable and permanent contact between the outer contact area and the bypass conductor. To provide the best possible protection against current passage, the bypass element is fastened in direct contact with the inner bearing ring against a shoulder on the first machine element.This provides reliable protection for the rolling bearing with a lower electrical resistance of the bypass device and enables a particularly space-saving arrangement.

[0009] Preferably, a particularly secure and simple attachment of the bypass device can be achieved if the holder of the bypass device also engages radially in a groove-shaped undercut between the inner bearing ring and the first machine element. This makes the attachment particularly space-saving, and only minimal axial space is required for the bypass device to ensure ideal positioning in the seating area.

[0010] In a preferred embodiment, the rolling bearing assembly has an annular contact element in the contact area of ​​the outer bearing ring, which is conductively connected to the outer bearing ring. Even if this seems disproportionate to the expert for economic reasons due to the increased, dimensionally accurate manufacturing, assembly, and material costs, this is consciously accepted to reduce the contact resistance in the contact area between the bypass conductor and the outer bearing ring and to protect the rolling bearing.

[0011] To make the arrangement even more space-saving, a further preferred embodiment provides that the outer contour of the annular contact element ends in the same plane YZ as the inner bearing ring in the direction of the rotation axis. This prevents the outer bearing ring from being widened by the annular contact element.

[0012] In another preferred embodiment, the electrical resistance in the contact area can be further reduced by selecting the material for the contact element. Although numerous materials, especially precious metals, are suitable, it has been found to be particularly advantageous if the contact ring contains the element Ag (silver). This represents an ideal compromise between improved conductivity and economic considerations. It is also conceivable that this is implemented only on the surface, i.e., in the form of a coating.

[0013] Furthermore, it is advantageous if the contact area of ​​the contact ring generates a lower electrical resistance to the bypass conductor than the other surfaces of the outer bearing ring. Due to the lubricant layer, an increased electrical resistance between the rolling elements and the outer bearing ring is to be expected compared to the transition from the bypass conductor to the contact ring, even if the outer bearing ring and the contact ring are made of the same material. However, to ensure the lowest electrical resistance at the transition from the bypass to the outer bearing ring or contact ring, even under exceptional circumstances, the contact area of ​​the contact ring preferably generates a lower electrical resistance to the bypass conductor than the other surfaces of the second bearing ring.

[0014] It is also particularly suitable if the holder of the bypass device is designed in two parts and comprises a retaining disc and a clamping disc that hold the bypass conductor. This allows even inherently unstable bypass conductors, i.e., those that lack reinforcement elements in the holding area, to be accommodated particularly well by the holder.

[0015] In a further preferred embodiment, the clamping disc of the holder of the bypass device has axially resilient elements. These serve, on the one hand, to make the holder elastic, allowing it to clamp the bypass conductor particularly well. On the other hand, by attaching the holder to a shoulder of the first machine element, they can generate an axial preload of the inner bearing ring, in the case of a floating bearing configuration.

[0016] To further improve this embodiment, the axially resilient elements can be designed as raised elements relative to the axial plane X, i.e., from the disc shape. These axially resilient elements thus combine two effects. Firstly, the bypass conductor is kept preloaded, and secondly, the inner bearing ring on the first machine element is preloaded. This can be achieved in a particularly suitable manner against a retaining ring on the side of the inner bearing ring opposite the shoulder on the first machine element.

[0017] Independently of the above or in combination thereof, the holder of the bypass device of the rolling bearing assembly may have annular openings.

[0018] This is particularly advantageous for so-called "wet" applications, i.e. in which the lubricant of an entire system also serves as rolling bearing lubrication. These annular recesses on the holder represent media-permeable openings. These can be designed with different geometries, i.e. in different annular segments or partial segments distributed around the circumference of the holder or as annular openings. They allow the passage of lubricant and at the same time prevent any pressure differences that may occur in the system, which would lead to excessive, damaging contact pressure of the bypass line on the second machine element. Depending on the position on the holder, it may be necessary to provide these openings on certain elements, for example a holding plate and a clamping plate, in a two-part or multi-part holder structure.This allows the lubricant to pass through the bypass device in an ideal manner.

[0019] It is conceivable for the retaining disc and the clamping disc to be caulked to each other. This caulking can create media-permeable, annular openings that are available on the holder during use. This is conceivable in the form of a circular through-hole being created through the retaining disc and the clamping disc by means of the caulking. This is particularly advantageous because the discs of the holder can be manufactured, i.e., joined, particularly efficiently in this way, while simultaneously creating media-permeable through-holes.

[0020] At least one electrical connection is established via the bypass device at least between the first and second machine elements. The design of the bypass device is focused exclusively on electrical conductivity and the installation situation, not on a sealing function. When integrating bypass conductors into sealing systems, compromises must be made regarding the material properties of the seals and also the bypass conductor. When designing the bypass conductor of a bypass device, it is advantageous to consider only the requirements for electrical conductivity and wear resistance when selecting and designing the material.

[0021] The bypass device consists of a holder and an electrically conductive bypass conductor. The holder is any component designed to hold the bypass conductor. The properties of the bypass conductor can be precisely tailored to the contact or discharge resistance of the rolling bearing.

[0022] As mentioned above, the holder and the bypass conductor are electrically connected. Generally, the bypass device is designed so that voltage potentials are discharged via this bypass device and not via the cylindrical roller set.

[0023] Two machine elements are mounted for rotation relative to one another by at least one cylindrical roller set. In this case, the first machine element, located closer to the rotation axis, is statically mounted, while the second machine element is mounted for rotation about the rotation axis of the rolling bearing by means of the cylindrical roller set. Machine elements are generally shafts, for example, rotor shafts of an electrical machine; housings, for example, bearing shields or housings or housing sections or bearing shields of an electrical machine; gears or shafts or housings of a transmission; or any other machine elements suitable for being mounted on or against one another by means of rolling bearings.

[0024] In the cases considered, the rotation axis of the cylindrical roller set is always axially aligned. Radial is perpendicular to the rotation axis.

[0025] The cylindrical roller set is used for the rotatable mounting of machine parts, elements and assemblies and has cylindrical rolling elements to reduce friction, which roll between the inner and outer bearing rings and thus reduce friction in the rotatable bearing.

[0026] The cylindrical roller set can have a cage to guide the rolling elements and, as already mentioned, is installed with an inner and an outer bearing ring to form a rolling bearing. Alternatively, the rolling bearing can also have more than just an inner and / or outer ring. In addition, the bearing ring, or the bearing rings, are alternatively split and have a raceway or part of a raceway. One or more outer raceways are formed on the radially inner contact partner, i.e. the inner ring, and one or more inner raceways are formed on the outer ring. The rolling elements rolling on the raceways are roller-shaped bodies. The rollers are, as already mentioned, often guided and held in cages. The rolling elements are either arranged in a row one behind the other in the circumferential direction or, alternatively, the arrangement comprises several rows of rolling elements arranged side by side. The bearing rings can be designed with or without rims.

[0027] In the context of the invention, a bypass is understood to mean the redirection of a current or voltage around one or more rolling bearings and / or machine parts. The rolling elements and the bearing ring are usually made of rolling bearing steel and touch each other at the raceway(s). The contact zones formed are potential passageways for currents, where the dreaded discharges lead to the damage to the raceways already described in the "Background of the Invention" chapter.

[0028] The currents are to be redirected through the bypass or bypass device. This can be "controlled" by ensuring that the bypass device, or in any case the bypass conductor, has comparatively lower electrical or specific electrical resistance than the rolling bearing.

[0029] It is conceivable that the cylindrical roller set on the inner bearing ring is insulated against the passage of current. For example, it is conceivable that an insulator or insulating layer is applied between the first machine element on / in which the bearing ring sits. The holder of the bypass device is connected to the first machine element by direct electrical contact, i.e., without an insulating layer or elements. It is conceivable that the rolling elements are made of a non-electrically conductive material such as ceramic. In this case, the bypass device only needs to redirect the current.

[0030] Although any material and configuration of the bypass conductor is conceivable, an advantageous embodiment of the rolling bearing assembly provides for the bypass conductor to be formed from loop-shaped, interwoven fibers. The term "interwoven fibers" used below refers to both individual fibers and fiber pairs or bundles. The term "interwoven" describes any joining of fibers, fiber pairs, or bundles that uses an additional thread for connection. Sewing, crocheting, or similar techniques can therefore also be considered equivalent.

[0031] The bypass conductor designed in this way represents an ideal way of transmitting current, even when in contact with lubricants. Furthermore, it allows the lubricant to flow through without causing pressure differences in the bearing or the overall system.

[0032] The looped, interwoven fibers of the bypass conductor of the rolling bearing assembly advantageously comprise carbon or carbon derivatives. These components are particularly suitable for conducting current in a bypass conductor of a rolling bearing assembly because they are characterized by high elasticity with a high elongation at break and very good electrical conductivity.

They show: - Fig. 1 - a partial section as an embodiment of a rolling bearing arrangement 1 in a partial section along the rotation axis 16; - Fig. 2 - a detailed view of the rolling bearing arrangement from Fig. 1 in an oblique partial section; - Fig. 3 - a partial section as a further embodiment of a rolling bearing arrangement 1 in a partial section along the rotation axis 16; - Fig. 4 - a detailed view of the rolling bearing arrangement from Fig. 3 in an oblique partial section; - Fig. 5 - a partial section as a further embodiment of a rolling bearing arrangement 1 in a partial section along the rotation axis 16; - Fig. 6 - a detailed view of the rolling bearing arrangement from Fig. 5 in an oblique partial section; - Fig. 7 - an embodiment of the bypass device 20; - Fig. 8 - a detailed view of the bypass device 20 from Fig. 7 in an oblique partial section; - Fig. 9 - a detailed view of the clamping disc 20.2 of the bypass device 20 from Fig. 7;

[0034] Fig. 1 and Fig. 2 - The rolling bearing assembly 1 is formed from the cylindrical roller set 5, a static inner bearing ring 7 and a rotatable outer bearing ring 2 and a bypass device 20 and has a first machine element 30 and a second machine element 31 (in Fig. 2 not shown for reasons of simplification). The second machine element 31 can be designed, for example, as a housing, the first machine element 30, for example, as a shaft or a hollow shaft. The cylindrical roller set 5 comprises a plurality of cylindrical rollers 8 and can have a cage 11. The bearing ring 2 is arranged concentrically on an axially aligned axis of rotation 16 of the cylindrical roller set 5. The cylindrical roller set 5 is provided with cylindrical rollers 8 arranged radially between the inner bearing ring 7 and the outer bearing ring 2, wherein the latter is directed radially transversely to the axis of rotation 16. An electrical connection is formed between the first machine element 30 and the second machine element 31 via the bypass device 20. The bypass device 20 has Fig. 1 comprises a holder 21 and an electrically conductive bypass conductor 23, wherein the holder 21 and bypass conductor 23 are electrically connected to each other. The holder 21 is secured by means of a positive fit between the inner bearing ring 7 and a shoulder 22 in the first machine element 30 and holds the bypass conductor 23. The holder 21 is in Fig. 1 is formed in two parts, with a retaining disc 21.1 and a clamping disc 21.2 ensuring the secure mounting of the bypass conductor 23. A contact area 14 is formed on the end face of the outer bearing ring 2, at which the electrical contact between the bypass conductor 23 and the outer bearing ring 2 is formed, with the bypass conductor 23 making axial contact with the contact area.

[0035] Fig. 2: Fig. 2 shows the embodiment of the rolling bearing arrangement from Fig. 1 also for reasons of simplification without the second machine element 31. The holder 21 of the bypass device 20 of the rolling bearing arrangement 1 has in Fig. 2 annular openings 24. This is particularly advantageous for so-called "wet" applications, i.e., in which the lubricant of an entire system also serves as rolling bearing lubrication. The annular openings 24 on the holder 21 can be designed as recesses and represent media-permeable openings. These can be designed with different geometries, i.e., distributed in different annular segments or sub-segments over the circumference of the holder, or as annular openings as in Fig. 1, and allow the passage of lubricant and at the same time prevent excessive, damaging contact pressure of the bypass conductor 23 on the second machine element 31 in the event of pressure differences that may occur in the system. Fig. Figure 2 also illustrates that the retaining disc 21.1 and the clamping disc 21.2 can be caulked to each other. The caulking creates media-permeable, annular openings 9 that are available on the holder 21 during use. Thus, the caulking creates circular through-holes 9 through the retaining disc 21.1 and the clamping disc 21.2.

[0036] Fig. 3 and Fig. 4: The holder 21 of the bypass device 20 engages in Fig. 3 and Fig. 4 ( Fig. 4 shows this in an oblique partial section (but without the second machine element 31) also radially into a groove-shaped undercut 28 between the inner bearing ring 7 and the first machine element 30. The groove-shaped undercut 28 is ideally a circumferential groove 12 which exposes the area of ​​the holder 21 that overlaps with the inner bearing ring 7. Thus, the contact between the holder 21 and the inner bearing ring 7 occurs in the area of ​​its shoulder. By means of axially springy elements 32, which are raised with respect to the plane X, which extends between the y- and z-axes (axes perpendicular to the direction of rotation), the preload between the shoulder 4 of the first machine element 30 and the inner bearing ring 7, with a stop on the retaining ring 10, can be generated, among other things. For this purpose, the bearing is designed as a floating bearing. Due to the exposure, the mobility of the inner bearing ring 7 in the x-direction is not inhibited.For a more detailed illustration of one possibility for implementing the axially resilient elements 32, see . Fig. 9. Fig. Figure 4 also illustrates that the retaining disc 21.1 and the clamping disc 21.2 can be caulked to each other. The caulking creates media-permeable, annular openings 9 that are available on the holder 21 during use. Thus, the caulking creates circular through-holes 9 through the retaining disc 21.1 and the clamping disc 21.2.

[0037] Figures 5 and 6 - Fig. 5 and shows a further embodiment of the rolling bearing arrangement 1, Fig. 6 The same in an oblique partial section but without the second machine element 31. Here, the rolling bearing arrangement 1 has in the contact area 14 in the outer bearing ring 2 an annular contact element 33, which is conductively connected to the outer bearing ring 2. As in Fig. As can be seen in Figure 5, the outer contour of the annular contact element can end in the same plane YZ as the inner bearing ring in the direction of the rotation axis. This is also illustrated by the line E in Fig. 5. This prevents the outer bearing ring 2 from being widened by the bypass device 20. Fig. Figure 6 also illustrates that the retaining disc 21.1 and the clamping disc 21.2 can be caulked to each other. The caulking creates media-permeable, annular openings 9 that are available on the holder 21 during use. Thus, the caulking creates circular through-holes 9 through the retaining disc 21.1 and the clamping disc 21.2.

[0038] Fig. 7 - A conceivable embodiment of the bypass device 20 is shown as a section with a through hole 24 pierced centrally by the rotation axis 16 in Fig. 7. The bypass device 20 comprises a holder 21 and a bypass conductor 23. The holder 21 is in Fig. 7 is constructed in two parts, with a retaining disc 21.1 and a clamping disc 21.2 ensuring secure mounting of the bypass conductor 23. The axially spring elements 32 can be seen. However, in detail, Fig. 9. For centering the clamping disc 21.2, the retaining disc 21.1 may have a rim 34 directed toward the bearing center.

[0039] Fig. 8 - Fig. 8 shows an oblique partial section of the bypass device 20 from Fig. 7. The holder 21 of the bypass device 20 has annular openings 24. This is particularly advantageous for so-called "wet" applications, i.e. in which the lubricant of an entire system also serves as rolling bearing lubrication. The annular openings 24 on the holder 21 represent recesses designed as media-permeable openings. In the embodiment shown, these are circular. In addition, the holding disk 21.1 and the clamping disk 21.2 are caulked to one another here. By means of the caulking, media-permeable, annular openings 9 are created and are available on the holder 21 during use. Thus, by means of the caulking, circular through-holes 9 are created through the holding disk 21.1 and the clamping disk 21.2.

[0040] Fig. 9 - Fig.Figure 9 illustrates one possible design for the clamping disc 21.2 of the holder 21 of the bypass device 20. Here, shaped elements 33 are raised relative to the X plane, which extends between the y- and z-axes (axes perpendicular to the direction of rotation), and form axially resilient elements 29 that can generate a preload in the rolling bearing assembly 1. The annular openings 24 are, on the one hand, circular in shape, and, on the other hand, distributed in different annular sub-segments over the circumference of the holder.
