Description

[0001] Bearing adjustment device, calender and method for producing a web-shaped product

[0002] The invention relates to a bearing adjustment device, a calender with a bearing adjustment device and a method for producing a web-shaped product, for example an electrode film.

[0003] Bearing adjustment devices according to the invention can be used, for example, in the production of films, e.g., plastic films. A plastic material can be introduced into a roll gap to produce a plastic film. The width of the roll gap, which can affect the film thickness and the production process, and thus the film quality, can be adjusted by a bearing adjustment device according to the invention. The film can be produced using a calender, which can have two rolls with a corresponding roll gap.

[0004] However, the bearing adjustment device according to the invention and / or calender according to the invention with corresponding bearing adjustment devices are not limited thereto, but can also be used or provided for the production of other products, in particular other web-shaped products or web-shaped materials.

[0005] For example, a calender according to the invention or a bearing adjustment device according to the invention can also enable or become a coating of a web-shaped carrier with a coating material. For example, a coating agent can be applied to a web-shaped carrier guided through a roll gap by a coating roller, the width of the roll gap being adjustable by the bearing adjustment device. This means, for example, that the roll gap can be adjusted as a function of the coating process, the coating material and / or the web-shaped carrier. Likewise, a roll gap can be adjusted by means of a bearing adjustment device according to the invention during powder milling and / or during the production of a polymer-metal dry film.

[0006] 1

[0007] REPLACEMENT BLADE (RULE 26) The bearing device can also be used to adjust engraving rollers or embossing rollers. Engraving devices or embossing devices can have a bearing device according to the invention.

[0008] Calenders are used, for example, in film production, particularly in the production of electrode films. The electrode films can then be used to produce an electrode for an electrical energy storage device such as a battery.

[0009] During the production of an electrode film, a powdered electrode precursor material is introduced into the nip of a calender roll pair and compressed, before being further processed into a dry electrode. A manufacturing method for a dry electrode is known, for example, from WO 2020 / 148410 Ä2.

[0010] The electrochemical capabilities of suitably manufactured electrode films or electrodes, e.g., the capacity and efficiency of battery electrodes, are determined by various factors such as the distribution of the active material, the binder, and additives; the physical properties of the materials contained therein, such as the particle size and surface area of ​​the active material; the surface properties of the active materials; and the physical properties of the electrode film, such as density, porosity, cohesion, and adhesion to a conductive element. Dry processing systems and processes traditionally utilize a high-shear and / or high-pressure processing step to disrupt and mix the electrode film materials. Such systems and processes can contribute to structural advantages over wet-processed electrode films.However, due to the high processing pressures, the rollers can bend during calendering, which can change the width of the roller gap, with negative effects on the quality of the produced electrode film. Adjusting the gap width is therefore desirable. To counteract this deflection of the rollers, axis crossing of the rollers can be performed, in which one or both of the rollers are pivoted about a rotational axis perpendicular to their longitudinal axis. A corresponding calender is known, for example, from EP 3792394 Ai, in which the roller or a roller bearing is pivoted in a circular arc via a rocker. This also results in an adjustment of the roller in a direction perpendicular to the main adjustment direction.

[0011] It is therefore an object of the present invention to provide a bearing adjustment device, a calender, and a method for producing an electrode film, in which a flexible and precisely adjustable adjustment of the roller and a flexible and precise adjustment of the gap width are realized, so that a high-quality electrode film can be produced. In preferred embodiments of the invention, a linear adjustment takes place only in one adjustment direction.

[0012] The object of the invention is achieved by a bearing adjustment device according to claim 1, a calender according to claim 14, and a manufacturing method according to claim 21. Preferred embodiments are the subject of the respective subclaims.

[0013] A first aspect of the invention relates to a bearing adjustment device comprising a rotatably mounted outer eccentric sleeve and a rotatable inner eccentric sleeve received in the outer eccentric sleeve, wherein the inner eccentric sleeve has a receptacle, wherein the outer eccentric sleeve and the inner eccentric sleeve are rotatable relative to one another and are configured such that, upon relative rotation of the outer eccentric sleeve to the inner eccentric sleeve, the center point of the receptacle is adjusted in an adjustment direction. In some embodiments, the outer eccentric sleeve and the inner eccentric sleeve can be rotatable relative to one another and can be configured such that, upon opposite rotation of the outer eccentric sleeve to the inner eccentric sleeve, the center point of the receptacle is adjusted in an adjustment direction. The adjustment direction can be a vertical direction.The bearing adjustment device thus allows simple and flexible adjustment of the holder and thus of a roller or roll mounted by the bearing adjustment device.

[0014] The outer eccentric sleeve and / or the inner eccentric sleeve can be substantially hollow-cylindrical. A wall thickness of the outer eccentric sleeve and / or the inner eccentric sleeve can vary in the circumferential direction. The receptacle can be cylindrical and / or round. The central axis of the receptacle can be an axis of symmetry of the receptacle. The central axis of the receptacle can be aligned perpendicular to the adjustment direction. The central axis can run in the extension direction of the receptacle. The central axis can be arranged centrally in the receptacle.

[0015] The central axis of the holder can be adjusted by a maximum distance in the adjustment direction of up to 20 mm. It can be provided that the center point of the holder can be adjusted by a maximum distance in the adjustment direction of up to 15 mm. In some embodiments, the center point of the holder can be adjusted by a maximum distance in the adjustment direction of 12 mm. In some embodiments, however, the maximum distance can also be greater or smaller, e.g. depending on a manufacturing process and / or a web-like material to be produced. The maximum distance can correspond to the maximum possible distance of the position of the central axis. The maximum distance can be measured between a "low point" of the central axis and a "highest point" of the central axis. The distance in the adjustment direction can be zero at the "low point". The low point can define a reference position of the central axis.If the distance to the reference position is measured, the distance at the "low point" can be zero. In some embodiments, the outer eccentric sleeve and the inner eccentric sleeve can be rotated such that the central axis is at the "low point", so that the distance can be zero. With further rotation of the outer eccentric sleeve and / or the inner eccentric sleeve, in some embodiments counter-rotation, the distance can increase due to the rotation until the maximum distance is reached, e.g. the central axis is at the "highest point". With further rotation, the distance can decrease again. In some embodiments, the maximum distance can depend on the dimensioning of the.

[0017] Replacement sheet] bearing adjustment device, the inner eccentric sleeve and / or the outer eccentric sleeve.

[0018] The outer eccentric sleeve and the inner eccentric sleeve can be configured such that, upon rotation of the outer eccentric sleeve in the opposite direction to the inner eccentric sleeve, the center point of the receptacle is not adjusted in a direction perpendicular to the adjustment direction. In some embodiments, the outer eccentric sleeve and the inner eccentric sleeve can be configured such that, upon rotation in the opposite direction, the center point of the receptacle is not adjusted in a horizontal direction.

[0019] The inner eccentric sleeve can have a first eccentric gear. The first eccentric gear can be or have a non-circular gear. The outer eccentric sleeve can have a second eccentric gear. The second eccentric gear can be or have a non-circular gear. If the first eccentric gear and / or the second eccentric gear is non-circular, an eccentricity of the inner bearing sleeve and / or the outer bearing sleeve can be compensated for such that the respective eccentric gear can be driven easily and simply with a simple or round gear, for example, a spur gear.

[0020] The first eccentric gear can be arranged on a first side of the bearing adjustment device, and the second eccentric gear can be arranged on a second side of the bearing adjustment device. The second side can be arranged opposite the first side. This allows the respective eccentric gears to be easily accessible, for example, to be driven by further gears. It can be provided that, with a corresponding arrangement of the eccentric gears, torques caused by their weight can also be at least partially compensated. In some embodiments, a center of gravity of the bearing adjustment device can also be moved closer to a geometric center of the bearing adjustment device and / or coincide with this, so that the bearing adjustment device can be or can be better held, for example after assembly.

[0021] The bearing adjustment device can have a drive that can be configured to drive and / or rotate the inner eccentric sleeve and / or the outer eccentric sleeve. In some embodiments, the drive can drive the inner eccentric sleeve and the outer eccentric sleeve independently of one another and / or individually. In some embodiments, the outer eccentric sleeve and the inner eccentric sleeve can be or are rotated independently of one another. In some other embodiments, the drive can drive the inner eccentric sleeve and the outer eccentric sleeve such that when the inner eccentric sleeve is rotated, the outer eccentric sleeve is also rotated, and / or vice versa.

[0022] The drive may comprise a manual adjustment, an electric motor, a stepper motor, an encoder drive and / or a hydraulic motor.

[0023] The drive may include a first gear coupled to the first eccentric gear, a second gear coupled to the first gear, and a third gear coupled to the second eccentric gear. The first gear may be or include a first spur gear. The second gear may be or include a second spur gear. The third gear may be or include a third spur gear.

[0024] The drive may include a shaft that can couple the second gear to the third gear. In some embodiments, the shaft may extend substantially parallel to the inner eccentric sleeve and the outer eccentric sleeve. The drive may be configured to drive and / or rotate the shaft, and / or apply a torque to the shaft.

[0025] The gear ratio of the first gear to the first eccentric gear, of the second gear to the first gear and of the third gear to the second eccentric gear can each be selected such that when the shaft rotates, the inner eccentric sleeve can be rotated relative to the second eccentric sleeve by the same angle in the opposite direction.

[0026] At least one of the gears can be a split gear and / or have at least two gear halves coupled to one another. It can be provided that one, several or all of the first eccentric gear, second eccentric gear, first gear, second gear and / or third gear can be a split gear and / or have at least two gear halves coupled to one another. The gear halves can be coupled and / or braced to one another, for example, via a spring, for example a torsion spring or an omega spring. Alternatively or additionally, the gear halves can be coupled and / or braced to one another using an elastic material. The elastic material can be arranged between the gear halves. The elastic material can be or comprise an elastomer, for example.

[0027] If a gear is split, the split can result in improved contact and / or meshing of the teeth of the split gear with the teeth of another gear, or better meshing. Gear backlash can be reduced or even eliminated.

[0028] The bearing adjustment device may include a second drive configured to drive the inner eccentric sleeve and / or the outer eccentric sleeve. The second drive may have one, several, or all of the features and / or advantages of the drive. The second drive may include a manual adjustment, an electric motor, a stepper motor, an encoder drive, and / or a hydraulic motor.

[0029] By preloading both drives against each other, the position of the eccentric sleeves can be held free of play. For example, one of the drives can block, and the other can build up a defined preload to eliminate play with any torque. In some embodiments, the second drive can be configured to drive and / or rotate the shaft and / or apply a torque to the shaft. It can be provided that the drive and second drive can rotate the shaft in the same and / or opposite direction of rotation and / or can each apply torques to the shaft in the same or opposite direction and / or with the same or different strengths.

[0030] The outer eccentric sleeve, the inner eccentric sleeve, and the receptacle can be aligned parallel to one another. It can be provided that the axes of rotation of the outer eccentric sleeve and the inner eccentric sleeve can be aligned parallel to one another and / or spaced parallel from one another. In some embodiments, the axes of symmetry of the outer eccentric sleeve, the inner eccentric sleeve, and the receptacle can be aligned parallel to one another and / or spaced parallel from one another.

[0031] The inner eccentric sleeve can protrude beyond the outer eccentric sleeve.

[0032] The first eccentric gear can be arranged such that it can axially secure the inner eccentric sleeve relative to the outer eccentric sleeve. The inner eccentric sleeve can have a first retaining ring that can axially secure the inner eccentric sleeve relative to the outer eccentric sleeve. The first retaining ring can be arranged opposite the first eccentric gear.

[0033] The outer eccentric sleeve can be rotatably mounted in a housing, wherein the second eccentric gear can axially secure the outer eccentric sleeve relative to the housing. The outer eccentric sleeve can have a second retaining ring that can axially secure the outer eccentric sleeve relative to the housing. The second retaining ring can be arranged opposite the second eccentric gear.

[0034] The bearing adjustment device can comprise a bearing that can be arranged in the receptacle. The bearing can be or comprise a roller bearing. For example, a roller or roll can be accommodated in the roller bearing. If a bearing is accommodated in the receptacle, the center axis of the receptacle can correspond to or coincide with a center axis of the bearing. If a roller or roll is accommodated in the

[0035] 8

[0036] Replacement sheet] bearing, the central axis of the mount may correspond to or coincide with a rotational axis of the roller or roll.

[0037] However, the bearing adjustment device according to the invention is not limited to calenders and / or calendering processes. Other applications are also conceivable.

[0038] A further aspect of the present invention relates to a calender comprising a bearing adjustment device as described above and a pair of rolls with a nip between the rolls of the roll pair, wherein one of the rolls is supported by the bearing adjustment device. Thus, one or both rolls of the roll pair can be pivoted relative to each other and / or axially crossed by adjusting the center axis of the mount. In some embodiments, alternatively or additionally, the nip can be flexibly and easily adjusted.

[0039] Each of the rollers in the roller pair can be supported at its lateral ends by a bearing adjustment device as described above. This allows the rollers to be pivoted relative to each other or crossed axially with even greater flexibility. Alternatively or additionally, the roller gap can be adjusted even more flexibly.

[0040] The calender can have a powder hopper for filling the roll gap with powder. This can ensure good and even filling of the roll gap. The powder can be or comprise a powdered electrode film precursor material.

[0041] The calender can have a support roll, which can laterally support one of the rolls in the roll pair. This allows transverse forces from the roll to be absorbed laterally by the support roll. The support roll can be mounted by another bearing adjustment device as described above. This allows the support roll to be adjusted. This ensures that even an adjusted roll can be laterally supported by the adjusted support roll.

[0042] One of the rolls of the roll pair can be pivoted and / or axially crossed relative to the other roll of the roll pair by adjusting the center axis of the bearing adjustment device holder in the adjustment direction. The adjustment and / or axial crossing, and / or the gap width of the roll gap, can be varied during operation. In some embodiments, the calender can have a sensor that can detect the adjustment and / or axial crossing, and / or the gap width of the roll gap. The adjustment can be performed during operation, for example, based on the data detected by the sensor.

[0043] Yet another aspect of the invention relates to a method for producing a web-shaped product using a calender, the method comprising the steps of:

[0044] Feeding a precursor material into a nip of a roll pair of the calender;

[0045] Producing the web-shaped product, wherein at least one of the rollers of the roller pair contacts the precursor material in the roller nip; wherein, during compression, at least one of the rollers of the roller pair is pivoted and / or axially crossed relative to the other roller, wherein the adjustment and / or axial crossing of the roller comprises adjusting a center axis of a bearing adjustment device supporting the roller and described above into an adjustment device. Thus, a web-shaped product of high and / or uniform quality can be or will be produced.

[0046] The calender may be or comprise a calender as described above.

[0047] 10

[0048] [Replacement sheet] The precursor material may comprise a plastic and the web-shaped product may be a plastic film, wherein during the manufacture of the web-shaped product the precursor material may be formed into the plastic film by the rollers.

[0049] The precursor material may comprise a web-shaped carrier and one of the rollers may be or comprise a coating roller, wherein during the production of the web-shaped product a coating agent may be applied to the web-shaped carrier by the coating roller.

[0050] The precursor material may comprise a powdered electrode film precursor material, wherein feeding the precursor material may comprise introducing the powdered electrode film precursor material into the roll gap; and wherein producing the web-shaped product may comprise compressing the powdered electrode film precursor material with the rolls of the roll pair of the calender.

[0051] Before introducing the powdered electrode film precursor material into the roll gap, the powdered electrode film precursor material can be filled into a powder hopper of the calender, and the powdered electrode film precursor material can be introduced into the roll gap with the powder hopper.

[0052] The compressed electrode film precursor material can be compressed into a film during compression. After compressing the electrode film precursor material, the compressed electrode film precursor material can be further pressed. The compressed electrode film precursor material can be further pressed using another pair of rollers.

[0053] The further compressed electrode film precursor material can be compressed into a film during further compression. After further compression, an electrode film can be formed, wherein the formation of the electrode film can comprise laminating the further compressed electrode film precursor material.

[0054] 11

[0055] [Replacement sheet] In some embodiments, it may alternatively be provided that an electrode film can be formed after compressing the electrode film precursor material, wherein forming the electrode film may comprise laminating the compressed electrode film precursor material.

[0056] In forming the electrode film, a first compressed electrode film precursor material and / or a first further compressed electrode film precursor material may be laminated onto a first side of the metal foil, and a second compressed electrode film precursor material and / or a second further compressed electrode film precursor material may be laminated onto a second side of the metal foil opposite the first side.

[0057] In some embodiments, one, several, or all of the steps of the described methods may be performed in a different order.

[0058] The invention is further explained with reference to the following figures. They show:

[0059] Fig. i: a perspective view of an embodiment of a bearing adjustment device according to the invention;

[0060] Fig. 2: a further perspective view of the embodiment shown in Figure 1;

[0061] Fig. 3: an exploded view of the embodiment shown in Figs. 1 and 2;

[0062] Fig. 4: a sectional view of the embodiment shown in Figs. 1 to 3; and

[0063] Fig. 5: a further sectional view of the embodiment shown in Figs. 1 to 4; and Fig. 6: a schematic view of an embodiment of a calender according to the invention.

[0064] Figures 1 to 5 show an embodiment of a bearing adjustment device 1 according to the invention. Figure 1 shows one side of the bearing adjustment device 1, and Figure 2 shows an opposite side. Figure 3 shows an exploded view of the bearing adjustment device 1. Figure 4 shows a cross-sectional view, and Figure 5 shows a longitudinal sectional view of the bearing adjustment device 1.

[0065] The bearing adjustment device 1 has an outer eccentric sleeve 2 and an inner eccentric sleeve 3. The outer eccentric sleeve 2 is rotatably mounted in the bearing adjustment device 1 and / or a housing 17 of the bearing adjustment device 1, for example by means of an eccentric sleeve bearing 24. The inner eccentric sleeve 3 is received in the outer eccentric sleeve 2 and rotatably mounted in the outer eccentric sleeve 2. The outer eccentric sleeve 2 and the inner eccentric sleeve 3 can be rotated in opposite directions. The outer eccentric sleeve 2 and / or the inner eccentric sleeve 3 can be substantially hollow-cylindrical and / or have a substantially hollow-cylindrical shape. The outer eccentric sleeve 2 and / or the inner eccentric sleeve 3 can be rotatable about a respective axis of rotation, which can be aligned parallel to an axial direction C of the bearing arrangement. The wall thickness of the outer eccentric sleeve and / or the inner eccentric sleeve can vary in the circumferential direction.

[0066] The inner eccentric sleeve 3 has a receptacle 4. A bearing (not shown in the figures), for example a rolling bearing, can be received in the receptacle 4. The bearing can be mounted in the receptacle 4 and / or fastened on or in it. The bearing can be or have, for example, a roller bearing or a ball bearing. The bearing can serve to support a roller and / or a cylinder. The receptacle 4 has a central axis A. The central axis A can be an axis of symmetry of the receptacle 4. The central axis A can run in the direction of extension of the receptacle 4. The central axis A can be arranged centrally in the receptacle 4. The outer eccentric sleeve 2 can be received in an outer eccentric sleeve receptacle 25 of the bearing adjustment device 1 (see, for example, Fig. 3). The inner eccentric sleeve 3 can be received in an inner eccentric sleeve receptacle 25 of the outer eccentric sleeve 2.The outer eccentric sleeve receptacle 25, the inner eccentric sleeve receptacle 26, and / or the receptacle 4 can be circular and / or cylindrical. A respective center point and / or respective center axes of the outer eccentric sleeve receptacle 25, the inner eccentric sleeve receptacle 26, and / or the receptacle 4 can be arranged eccentrically and / or non-coincidentally.

[0067] When the outer eccentric sleeve 2 and / or the inner eccentric sleeve 3 rotates, the center axis A of the receptacle 4 of the inner eccentric sleeve 3 can be or become adjusted in an adjustment direction V due to the eccentricity of the outer eccentric sleeve 2 or the inner eccentric sleeve 3.

[0068] Preferably, the outer eccentric sleeve 2 and the inner eccentric sleeve 3 can be or are rotated in opposite directions such that the central axis A or points on the central axis 4 are only adjusted in the adjustment direction V. In other words, it can be provided that the opposite rotation of the outer eccentric sleeve 2 and the inner eccentric sleeve 3 compensates for an adjustment of the central axis A in a direction H perpendicular to the adjustment device, so that the central axis A or points on the central axis A are not or will not be adjusted in the direction H. For example, the outer eccentric sleeve 2 and the inner eccentric sleeve 3 can be designed such that upon opposite rotation by a respective angle of rotation of the same amount, the central axis is or will only be adjusted in the adjustment direction V. It can be provided that the central axis A moves and / or is or will move or adjust linearly in the adjustment direction V.This can, for example, enable precise adjustment of a roller gap.

[0069] For the exemplary embodiment shown as an example, with the alignments of the outer sleeve 2 and inner sleeve 3 shown in Figures 1 and 2 along the adjustment direction V, the central axis A can be arranged at a "low point". When rotated in the opposite direction by 180°, the central axis A can have a maximum distance d relative to this low point in the adjustment direction V, i.e. the central axis B adjusted in this way can be spaced less than the maximum distance d in the adjustment direction V, parallel to the central axis running through the "low point". When rotated in the opposite direction up to an angle (amount) of 180°, the distance d can increase up to the maximum distance. When rotated in the opposite direction beyond 180°, the distance d can decrease again until it can be zero when rotated through an angle (amount) of 360°.The maximum distance d and thus the maximum adjustment of the central axis A in the adjustment direction V can, in some embodiments, be a maximum of 20 mm. The maximum distance d and thus the maximum adjustment of the central axis A in the adjustment direction V can, in some embodiments, be a maximum of 15 mm. The maximum distance d and thus the maximum adjustment of the central axis A in the adjustment direction V can, in some embodiments, be a maximum of 12 mm. The maximum distance d and thus the maximum adjustment of the central axis A in the adjustment direction V can, in some embodiments, be a maximum of 10 mm. In some embodiments, it can be provided that the maximum distance d is 12 mm. A maximum distance d of 10 mm to 20 mm, for example of 12 mm, can be provided in some embodiments during the production of plastic films. However, it can also be provided that the maximum distance d is greater or smaller.The maximum distance d can be selected depending on the intended manufacturing process, the intended use of the bearing adjustment device and / or the calender, and / or the web-like product or material to be produced. The maximum distance d can be selected, for example, by appropriately selecting the dimensions and / or eccentricity of the outer eccentric sleeve 2, the inner eccentric sleeve 3, and / or the receptacle 4.

[0070] In some embodiments, the adjustment direction V can be a vertical direction. In some embodiments, the direction H can be a horizontal direction. Depending on the orientation of the bearing device and / or the design of the outer eccentric sleeve 2 and inner eccentric sleeve 3, other adjustment directions V are also possible. If a bearing, e.g. a rolling bearing, is accommodated in the receptacle 4, the axis of rotation of the bearing accommodated in the receptacle 4 can be or become adjusted accordingly in the adjustment direction V. A roller or roll mounted by the bearing or the bearing device 1 can therefore also be adjusted accordingly.

[0071] In some other embodiments, the outer eccentric sleeve 2 and the inner eccentric sleeve 3 can be or can be rotated by different angles and / or in the same direction of rotation in order to adjust the central axis A both in the adjustment direction V and in the direction H. In some embodiments, alternatively or additionally, the shape of the outer eccentric sleeve 2 and / or the inner eccentric sleeve 3 can be selected such that the central axis A can be adjusted both in the adjustment direction V and in the direction H. The angle of rotation, direction of rotation and / or shape of the outer eccentric sleeve 2 and / or the inner eccentric sleeve 3 can be suitably selected in order to enable a predetermined adjustment of the central axis A of the receptacle 4 in the adjustment direction V and direction H. If a bearing is accommodated in the receptacle 4, e.g. a rolling bearing, the axis of rotation of the bearing accommodated in the receptacle 4 can thus be adjusted accordingly in the adjustment direction V and direction H.This enables a particularly flexible adjustment of the central axis A, and thus of a bearing accommodated in the holder 4 or of a roller or cylinder mounted by the bearing device 1.

[0072] The bearing adjustment device 1 can have a drive 10. The drive 10 can be configured to drive and / or rotate the inner eccentric sleeve 3 and / or the outer eccentric sleeve 2. The inner eccentric sleeve 3 can have a first eccentric gear 6. The first eccentric gear 6 can be arranged on an outer side of the inner eccentric sleeve 3 and / or enclose the inner eccentric sleeve 3. Alternatively, in some embodiments, the first eccentric gear 6 can also be an internal gear and / or arranged on an inner side of the inner eccentric sleeve 3. The outer eccentric sleeve 2 can have a second eccentric gear 7. The second eccentric gear 7 can be arranged on an outer side of the outer eccentric sleeve 2 and / or enclose the outer eccentric sleeve 2.Alternatively, in some embodiments, the second eccentric gear 7 can also be an internal gear and / or can be arranged on an inner side of the outer eccentric sleeve 2. The first eccentric gear 6 can be arranged on one side of the bearing adjustment device 1, and the second eccentric gear 7 can be arranged on an opposite side of the bearing adjustment device 1, as shown, for example, in Figures 3 and 5.

[0073] The drive 10 can have a first gear 11. The first gear 11 can be coupled to the first eccentric gear 6 so that a rotation of the first gear 11 can be or is transmitted to the first eccentric gear 6, and / or vice versa. The drive 10 can have a third gear 13. The third gear 13 can be coupled to the second eccentric gear 7 so that a rotation of the third gear 13 can be or is transmitted to the second eccentric gear 7, and / or vice versa. It can be provided that the drive 10 has a second gear 12. The second gear 12 can be coupled to the first gear 11 so that a rotation of the second gear 12 can be or is transmitted to the first gear 11, and thus indirectly to the first eccentric gear 6, and / or vice versa. The first gear 11 may be or comprise a spur gear. The second gear 12 may be or comprise a spur gear.The third gear 13 can be or have a spur gear.

[0074] It can be provided that the first eccentric gear 6 is non-circular. If the outer eccentric sleeve 2 is eccentric and / or the outer eccentric sleeve receptacle 25 is eccentric to the inner eccentric sleeve receptacle 26, the corresponding eccentricity can be or will be compensated for by the non-circular first eccentric gear 6, so that the first gear 11 can be a round gear, e.g. a spur gear, to drive the first eccentric gear 6. It can be provided that the second eccentric gear 7 is non-circular. If the inner eccentric sleeve 3 is eccentric and / or the inner eccentric sleeve receptacle 25 is eccentric to the receptacle 4, the corresponding eccentricity can be or will be compensated for by the non-circular second eccentric gear 7, so that the third gear 13 can be a round gear, e.g. a spur gear, to drive the second eccentric gear 7.At least one of the gears 6, 7, 11, 12, 13 can be a split gear and / or have at least two gear halves coupled to one another (not shown in the figures). For example, it can be provided that one, several, or all of the first eccentric gear 6, the second eccentric gear 7, the first gear 11, the second gear 13, and / or the third gear 13 can be a split gear and / or have at least two gear halves coupled to one another. The gear halves can be coupled and / or braced to one another, for example, via a spring, for example a torsion spring or an omega spring. Alternatively or additionally, the gear halves can be coupled and / or braced to one another via an elastic material. The elastic material can be arranged between the gear halves. The elastic material can be or have an elastomer, for example.If a gear is split, the split can result in improved contact and / or meshing of the teeth of the split gear with the teeth of another gear, or better meshing. Gear backlash can be reduced or even eliminated.

[0075] It can be provided that the drive 10 has a shaft 14. The shaft 14 can extend substantially parallel to the outer eccentric sleeve 2 and the inner eccentric sleeve 3, for example parallel to the axial direction C. The shaft 14 can couple the second gear 12 to the third gear 13. Thus, upon rotation of the shaft 14, an opposite rotation of the outer eccentric sleeve 2 to the inner eccentric sleeve 3 can result. In some embodiments, the gear ratio of the first gear 11 to the first eccentric gear 6, of the second gear 12 to the first gear 11, and of the third gear 13 to the second eccentric gear 7 can be selected such that upon rotation of the shaft 14, the outer eccentric sleeve 2 and the inner eccentric sleeve 3 are or will be rotated in opposite directions relative to one another by the same angular amount.In some embodiments, it may be provided to select the respective gear ratio by a suitable number of teeth of the respective gears.

[0077] The bearing adjustment device 1 may include a second drive (not shown in the figures) that may be configured to drive the inner eccentric sleeve 3 and / or the outer eccentric sleeve 2. The second drive may have one, several, or all of the features and / or advantages of the drive 10. The second drive may include a manual adjustment, an electric motor, a stepper motor, an encoder drive, and / or a hydraulic motor.

[0078] By preloading both drives against each other, the position of the eccentric sleeves 2, 3 can be held free of play. For example, one of the drives can block, and the other can build up a defined preload to eliminate play with any desired torque. In some embodiments, the second drive can be configured to drive and / or rotate the shaft 14 and / or apply a torque to the shaft 14. It can be provided that the drive 10 and the second drive can rotate the shaft 14 in the same and / or opposite direction of rotation and / or can each apply torques in the same or opposite direction and / or with the same or different strengths to the shaft 14.

[0079] The shaft 14 can be rotatably mounted in the bearing adjustment device 1 and / or the housing 17 of the bearing adjustment device 1 by means of a gear rolling bearing 19.

For example, the first retaining ring 15 can secure the inner eccentric sleeve 3 relative to the second eccentric sleeve 2 in a second axial direction. The first and second axial directions can be aligned opposite one another.Thus, in some embodiments, the inner eccentric sleeve 3 can be axially secured relative to the outer eccentric sleeve 2 by the first retaining ring 15 and the first eccentric gear 6 and / or the protruding web.

[0082] As can be seen from Figure 5, for example, the outer eccentric sleeve 2 can project beyond the eccentric sleeve bearing 24, by means of which the outer eccentric sleeve can be rotatably mounted relative to the housing 17 and / or the bearing adjustment device 1. In this way, the outer eccentric sleeve 3 can be or become easily axially secured relative to the eccentric sleeve bearing 24, or the housing 17 and / or the bearing adjustment device 1. In some embodiments, the second eccentric gear 7 and / or a web protruding from the outer eccentric sleeve 2 can secure the outer eccentric sleeve 2 relative to the eccentric sleeve bearing 24 in a first axial direction. It can be provided that the outer eccentric sleeve 2 has a second retaining ring 16, which can axially secure the outer eccentric sleeve 2 relative to the eccentric sleeve bearing 24.For example, the second retaining ring 16 can secure the outer eccentric sleeve 2 relative to the eccentric sleeve bearing 24 in a second axial direction. The first and second axial directions can be oriented opposite to each other. Thus, in some embodiments, the outer eccentric sleeve 2 can be axially secured relative to the eccentric sleeve bearing 24, or the housing 17 and / or the bearing adjustment device 1, by the second retaining ring 16 as well as the second eccentric gear 7 and / or the protruding web.

[0083] An embodiment of a calender 100 according to the invention is shown in Figure 6. The calender 100 has at least one bearing adjustment device 1 according to the invention (not shown in Figure 6). The bearing adjustment device 1 can have one, several, or all features of the bearing adjustment devices 1 described above and shown in Figures 1 to 5.

[0084] The calender 100 has a roll pair formed from two rolls 102. A roll nip 104 is formed between the rolls 102. The calender 100 can be configured to produce a web-shaped material and / or to be used in at least one step of the production process. For example, the calender 100 can be used in the production of films, e.g., plastic films. In some embodiments, a material, e.g., a plastic material, can be introduced into the roll nip 104 and formed into a film, e.g., a plastic film, by the rolls 102. The bearing adjustment device 1 can be used to vary the roll nip 104 in order to adjust, for example, the film thickness and film quality. In some other embodiments, the calender 100 can be configured or used to coat a web-shaped carrier.The web-shaped carrier can be or be guided through the roll gap, and one or both of the rolls 102 can be configured to apply a coating material to the web-shaped carrier. The bearing adjustment device 1 can serve to vary the roll gap 104 in order to adjust, for example, the thickness of the coating and / or the coated web-shaped carrier, and / or their quality. In some other embodiments, the calender 100 can be configured to be used in powder milling and / or to produce a polymer-metal dry film. In some other embodiments, the calender 100 can be configured to produce an electrode, in particular a dry electrode, and / or an electrode precursor, or can be used in the production thereof.

[0085] The bearing adjustment device 1 can support a lateral end of a roller 102. If the central axis A of the receptacle 4 of the bearing adjustment device 1 is adjusted in the adjustment direction V (and / or in some embodiments alternatively or additionally in the direction H), the rotational axis of the roller 102 can be adjusted accordingly. In some embodiments, both ends of the roller 102 can be supported by a respective bearing device 1. In some embodiments, both rollers 102 of the roller pair, and / or both lateral ends of both rollers 102 of the roller pair, can be supported by a respective bearing device 1. By adjusting one, several, or all central axes A of one or more bearing adjustment devices 1, one or both of the rollers 102 can be pivoted or axially crossed relative to the other roller 102 of the roller pair.It can be provided that none, several, or all of the bearing adjustment devices 1 are or will be adjusted equally. Thus, the axis intersection of the rollers 102 and / or the thickness of the roller gap 104 can be or will be adjusted flexibly and easily, even during operation.

[0086] The calender may have a powder hopper 101. A powdered electrode film precursor material may be filled into the powder hopper 101. The powder hopper 101 may be configured to discharge the electrode film precursor material into the nip 104. The electrode film precursor material discharged into the nip 104 may be compressed by the nip rollers 102. In some embodiments, the calender 100 may have a support roller 103. The support roller 103 may be arranged such that it can laterally support a roller 102 of the roller pair, for example, to support the roller 102 against lateral transverse forces. In some embodiments, the support roller 103 may contact the roller 102. It can be provided that the calender 100 can have two support rollers 103, wherein each of the rollers 102 of the roller pair can be supported laterally by one of the support rollers 103.

[0087] In some embodiments, one or both of the support rollers can be supported at one or both lateral ends by a respective additional bearing adjustment device 1. Thus, the support roller 103 can be adjusted accordingly when adjusting the roller 102 (e.g., in the adjustment direction V and / or direction H), in order to ensure lateral support even when the roller 102 is adjusted.

[0088] The bearing adjustment device 1 can, for example, also be used to adjust engraving rollers or embossing rollers. Engraving devices or embossing devices can have one or more bearing devices 1. An engraving device can, for example, have at least one engraving roller, which can be mounted with a bearing device 1. An embossing device can, for example, have at least one embossing roller, which can be mounted with a bearing device 1. For example, the bearing device 1 can adjust an engraving and / or embossing force exerted by the engraved roller and / or embossing roller on an object to be engraved or embossed by adjusting the height and / or position of the engraved roller and / or embossing roller. Depending on the material of the object to be embossed or engraved, and / or type, shape, or e.g.also depth of the engraving or embossing, the bearing adjustment device 1 can adjust the engraving roller and / or embossing roller suitably or accordingly, and / or the engraving roller and / or embossing roller can be or will be adjusted by the bearing adjustment device 1.

[0089] The invention further relates to a method for producing an electrode film (not shown in the figures). Powdered electrode film precursor material can be compressed by a calender 100 as described above. As described above, at least one of the rollers can be pivoted relative to the other roller and / or axially crossed to ensure a good and uniform quality of the compressed electrode film precursor material.

[0090] After compression, the compressed electrode film precursor material can be film-shaped. In some embodiments, it can be provided that the electrode film precursor material is compressed to a thickness that is greater than the thickness of the electrode film precursor material to be subsequently laminated to a metal foil. It can be provided that, after compression, the compressed electrode film precursor material is further compressed. For this purpose, for example, an additional pair of rollers can be provided. The additional pair of rollers can have a suitable roller gap width, which can, for example, be smaller than the gap width of the roller gap 104 of the rollers 102 for compressing the powdered electrode film precursor material. It can be provided that one or both rollers of the roller pair are mounted with one or more of the bearing adjustment devices 1 described above for further pressing the compressed electrode film precursor material.

[0091] After further pressing, the further pressed electrode film precursor material may be film-shaped. The thickness of the further pressed electrode film precursor material may be smaller than the thickness of the compressed electrode film precursor material. The thickness of the further pressed electrode film

[0092] Precursor material may correspond to the thickness of the electrode film precursor material to be subsequently laminated onto a metal foil.

[0093] The further compressed electrode film precursor material can then be laminated onto a metal foil to form an electrode film. The lamination can be performed using a further pair of rollers, wherein in some embodiments, the further pair of rollers can be supported by at least one bearing adjustment device 1. In some embodiments, a further compressed electrode film precursor material can be laminated onto both sides of the metal foil, so that a double-sided laminated electrode film can be formed.

[0094] In some embodiments, the compressed electrode film precursor material may already have a thickness with which it can be laminated to the metal foil to form the electrode film. In these cases, it may be provided that further pressing can be omitted, so that the compressed electrode film precursor material can be laminated to the metal foil during lamination. In some embodiments, it may be provided that a compressed electrode film precursor material is laminated to both sides of the metal foil, so that a double-sided laminated electrode film can be formed.

[0095] The formed electrode film can then be used, for example, to produce a dry electrode.

[0096] The features disclosed in the claims, the description and the figures may be essential for the realization of the invention, individually or in any combination.
